Nanopollution Revised

Since naturally occurring nanoparticles are not pollutants (according to my personal opinion and of some authors), nanopollution only began after the appearance of nanofabrication of nanoengineered nanoparticles that are hazardous to the environment. Therefore, nanopollution is a considerably recent phenomenon.

Preface

In my last article ("nanopollution") I wrote about this subject briefly. After publishing the article, I reviewed some concepts. My ideas were consolidated and I believe that my perspective changed for the better. Thus, for reasons of loyalty to my readers, here are my revised concepts of nanopollution.


Introdution

Following my article "The Roots of Nano-Fear Decoded", I start here an attempt to point out ways and propose solutions in order to demystify the nano-fear.

From what I can understand, the roots of fear seem to be of the fasciculate type. In other words, there are not a "primary root" and "secondary roots". I choose to state that they all have approximately an identical importance.

Addressing nanopollution without addressing nanotoxicity is in theory and in practice an artificial effort, I'd say. Nanopollution exists in the environment and affects the biosphere (including Humans). The biosphere is exposed to nanotoxicity and, in turn contaminates the environment. We are therefore facing an indissociable circle. However, due to space limitations, this article will try to address nanopollution revised. Later I will write about combating nanopollution. Only then I will address nanotoxicity. Naturally, what I write is in line with my way of understanding this issue, in the present.

Before I start writing about nanopollution, I propose a brief analysis of pollution as a concept.


Pollution

Pollution is the introduction of contaminants in the natural environment. Pollution causes instability, several disorders, harm or discomfort to the ecosystem.

The ecosystem comprises:

• Physical systems;
• Systems of living organisms (including humans)

Pollution may involve:

• Chemicals;
• Energy in various forms (e.g. heat, noise, radiation).

The presence of pollutants in the environment is the cause pollution. Pollutants may be coming from either:

• Naturally occurring substances (or energies);
• Substances (or energy) which is strange to the environment (contaminants).

Nanopollution


I will continue to follow the same thinking regarding pollution.

Nanopollution is the introduction of nanosized contaminants in the natural environment. Nanopollution causes instability, several disorders, harm or discomfort to the ecosystem.

The ecosystem is the same, whether we are addressing pollution or nanopollution. The ecosystem comprises:

• Physical systems;
• Systems of living organisms (including humans)

The presence of nanopollutants in the environment is the cause nanopollution.


Nanoparticles

Some authors claim that the nanopollutants can be naturally occurring nanoparticles or nanoengineered nanoparticles.

In the case of naturally occurring particles, however, some authors claim that these are non-polluting. Personally, I share this position. Nature produces and always produced nanoparticles. I believe that naturally occurring nanoparticles have always existed on our planet, even before there was life. Naturally occurring nanoparticles have never constituted an obstacle to that life came up our planet. These naturally occurring nanoparticles also have never been an obstacle to biological evolution of species until today.

Follow some examples of naturally occurring nanoparticles:

• Nanoparticles expelled by volcanoes, along with ash and other natural materials;
• Nanoparticles naturally occurring on the ocean spray; formed by the violent burst of waves;
• Nanoparticles naturally occurring in mineral composites;
• Nanoparticles naturally produced by living organisms.

Nature produces mechanisms for its own balance. If naturally occurring nanoparticles are produced by nature, then, not only are not pollutants as also play a necessary role in establishing the ecological equilibrium. This is my personal opinion about naturally occurring nanoparticles.

Regarding, nanoengineered nanoparticles, as I pointed out on "The Roots of Nano-Fear Decoded", nanoengineered nanoparticles are nanoparticles produced by Humans that have been specifically designed for a specific function (e.g. packaging coating, protection of radiation in sunscreens).

In the case of nanoengineered nanoparticles, I have to put this idea very clearly. Nanoegineered nanoparticles do not necessarily have to be nanopollutants: some may be nanopollutants to the environment; others may be harmless to the environment and some can even be beneficial to the environment. Only through intensive study and detailed nanocharacterization (among other scientific studies) it is possible to demonstrate - based on scientific evidence - the degree of hazard (or the degree of benefit) of each nanoengineered nanoparticle to the environment.

Still with respect to nanoengineered nanoparticles, I believe they only recently came into existence through the processes of nanofabrication.

Studies suggest that nanoparticles are, by nature, extremely reactive. This means that the nanoparticles are most commonly found clustered in groups or linked to other atoms, nanostructures, organic material or blends than in its native form. With respect to the nanoengineered particles that are pollutants to the environment, and the ones which are nanotoxic, these authors claim that, through high reactivity, the degree of hazard or toxicity is greatly reduced.


How Can The Environment Spread Nanoparticles to The Entire Biosphere?

Nanoparticles are present in the air, in the water and in the soils. All requirements for the entire biosphere is contaminated with the ubiquity of nanoparticles are gathered.

For example, nanoparticles present in the air:

• Mix with humidity also present in the air. Consequently, precipitation (e.g. rain, sleet, snow) become contaminated with nanoparticles. Precipitation reaches the soils and the open water (oceans, seas, rivers, lakes); 
• Are incorporated in plants through their by the aerial components, for the processes of photosynthesis and respiration; 
• Are incorporated in animals through respiration; 
• Contaminate food exposed to air; 
• Contaminate drinking water exposed to air; 
• Are mixed with open water (e.g. oceans, rivers, streams, creeks, lakes); 
• Are infiltrated in soils.

For example, nanoparticles present in the water:

• Pass into the atmosphere accompanying the water vapour during the evaporation of water;
• Contaminate soils (trough groundwater);
• Are absorbed by roots of aquatic plants;
• Are absorbed by aquatic animals;
• Contaminate food during the process of washing with water and when water is used to cook.

Nanoparticles present in soils:

• Pass into the atmosphere accompanying the water vapour during the evaporation of water; 
• Are absorbed by underground roots of terrestrial plants; 
• Are absorbed by underground and terrestrial animals; 
• Contaminate groundwater. 

On the other hand, nanoparticles present into plants and animals traverse the entire food chain until reach Humans.


Final Comments

There are some ideas that I want to present here:

• Since naturally occurring nanoparticles are not pollutants (according to my personal opinion and of some authors), nanopollution only began after the appearance of nanofabrication of nanoengineered nanoparticles that are hazardous to the environment. Therefore, nanopollution is a considerably recent phenomenon; 
• Regardless of the degree of risk of nanoengineered nanoparticles (pollutants, harmless or beneficial), they are present in the environment and human beings are exposed to them.

Nanopollution

This is an indisputable fact: regardless of the origins of nanoparticles (naturally occurring nanoparticles or nanoengineered nanoparticles), they are present in the environment. Nanopollution exists in the environment and affects the entire biosphere (including Humans).

Introduction

Following my last article ("The Roots of Nano-Fear Decoded"), I start here an attempt to point out ways and propose solutions in order to demystify the nano-fear.

From what I can understand, the roots of fear seem to be of the fasciculate type. In other words, there are not a "primary root" and "secondary roots". I choose to state that they all have approximately an identical importance.

Only then I will address nanotoxicity. Naturally, what I write is in line with my way of understanding this issue.

Before I start writing about nanopollution, I propose a brief analysis of pollution as a concept.


Pollution

Pollution is the introduction of contaminants in the natural environment. Pollution causes instability, several disorders, harm or discomfort to the ecosystem.

The ecosystem comprises:

• Physical systems;
• Systems of living organisms (including humans)

Pollution may involve:

• Chemicals;
• Energy in various forms (e.g. heat, noise, radiation).

Pollutants are the components of pollution. Pollutants may be coming from either:

• Naturally occurring substances (or energies);
• Substances (or energy) that are strange to the environment (contaminants).

Let us focus on chemical substances as pollutants.


Nanopollution


I will continue to follow the same thinking regarding pollution.

Nanopollution is the introduction of nanosized contaminants in the natural environment. Nanopollution causes instability, several disorders, harm or discomfort to the ecosystem.

The ecosystem is the same, whether we are addressing pollution or nanopollution. The ecosystem comprises:

• Physical systems;
• Systems of living organisms (including humans)

Nanopollutants are the components of nanopollution. Nanopollutants may be coming from either:

• Naturally occurring nanosized substances;
• Nanosized substances that are strange to the environment (nanocontaminants).

Translating "nanosized substances" to a more accurate term, I would use the term nanoparticles (NPs).

In fact, there are two types of NPs causing nanopollution:

• Naturally occurring nanoparticles;
• Nanoengineered nanoparticles (NENPs) or, in other words, engineered nanoparticles.

Regarding naturally occurring nanoparticles, nature produces and always produced nanoparticles. I believe that naturally occurring NPs have always existed on our planet, even before there was life. Follow some examples of naturally occurring nanoparticles:

• Nanoparticles expelled by volcanoes, along with ash and other natural materials;
• Nanoparticles naturally occurring on the ocean spray; formed by the violent burst of waves;
• Nanoparticles naturally occurring in mineral composites.

How easily it can be concluded, naturally occurring nanoparticles have never constituted an obstacle to that life came up our planet. These naturally occurring nanoparticles also have never been an obstacle to biological evolution of species until today.

With regard to NENPs, I believe they only recently came into existence through the processes of nanofabrication.

As I pointed out on "The Roots of Nano-Fear Decoded", NENPs are nanoparticles produced by Humans that have been specifically designed for a specific function (e.g. packaging coating, protection of radiation in sunscreens).


How Can The Environment Spread Nanoparticles to The Entire Biosphere?

Nanoparticles are present in the air, in the water and in the soils. All requirements for the entire biosphere is contaminated with the ubiquity of nanoparticles are gathered.

For example, nanoparticles present in the air:

• Mix with humidity also present in the air. Consequently, precipitation (e.g. rain, sleet, snow) become contaminated with nanoparticles. Precipitation reaches the soils and the open water (oceans, seas, rivers, lakes); 
• Are incorporated in plants through their by the aerial components, for the processes of photosynthesis and respiration; 
• Are incorporated in animals through respiration; 
• Contaminate food exposed to air; 
• Contaminate drinking water exposed to air; 
• Are mixed with open water (e.g. oceans, rivers, streams, creeks, lakes); 
• Are infiltrated in soils.

For example, nanoparticles present in the water:

• Pass into the atmosphere accompanying the water vapour during the evaporation of water;
• Contaminate soils (trough groundwater);
• Are absorbed by roots of aquatic plants;
• Are absorbed by aquatic animals;
• Contaminate food during the process of washing with water and when water is used to cook.

Nanoparticles present in soils:

• Pass into the atmosphere accompanying the water vapour during the evaporation of water; 
• Are absorbed by underground roots of terrestrial plants; 
• Are absorbed by underground and terrestrial animals; 
• Contaminate groundwater. 

On the other hand, nanoparticles present into plants and animals traverse the entire food chain until reach Humans.

Therefore, this is an indisputable fact: regardless of the origins of nanoparticles (naturally occurring nanoparticles or nanoengineered nanoparticles), they are present in the environment and humans are exposed to them.

The Roots of Nano-Fear Decoded

In my opinion, it is impossible to isolate the responsible for the roots of nano-fear. The world and society are too complex and dynamic for such a task. However, it is possible to identify "clouds of higher probabilistic density" where responsibility for the roots of nano-fear is more likely to be located. This article will try to decode the roots of nano-fear. Or rather, I will try to decode those which are the main roots of nano-fear (or at least some of them).

Introduction

Whenever a new technology with relevance emerges; whenever the science shows to the world an important discovery, usually a whole range of complex and dynamic processes are initiated. Follow some of them (not necessarily in that order):

• The industry triggers a race to introduce new product offerings and services into commercial channels;
• If applicable, the field of medicine or health care develops applications of this new emerging technology or scientific discovery with relevance, to improve the health and welfare of populations; 
• Regulatory authorities study, monitors, discuss and evaluate the whole process of innovation under various angles and develop work that will generate legislation;
• Communication professionals communicate (or deliver) to the world news, stories and a whole range of information regarding this new emerging technology or scientific discovery with relevance;
• Part of the population (usually with less access to information) reacts with fear and suspicion (although this is not a generalized rule, it often happens).

It is also generally known and common sense that a new emerging scientific or technological discovery with relevance can be used for various purposes (whatever they are).

The principles that I presented above are also applicable to nanoscience and nanotechnology. Processes and their dynamics did not happen suddenly. However, succeeded very gradually, over the years.

After Richard Phillips Feynman, December 29th, 1959 presented the famous talk at the annual meeting of the American Physical Society at the California Institute of Technology (Caltech), called "There’s Plenty of Room at the Bottom" the world in general was not prepared for the reach of his message.

The words of Richard P. Feynman needed interpretation, the recognition that he obtained through a Nobel Award and the development of many scientific studies, so that a significant part of the world could understand the importance of he said.

In fact, as I wrote in "The Origins of Nanotechnology", the Nobel Prize in Physics 1965 was awarded jointly to Sin-Itiro Tomonaga, Julian Schwinger and Richard P. Feynman "for their fundamental work in quantum electrodynamics, with deep-ploughing consequences for the physics of elementary particles".

Thus, the scientific and technological advances in nanoscience and nanotechnology gradually succeeded over the years. In the last decade, the number of discoveries and published articles has increased in a way - I would say - approximately exponential.

During this last decade, the media also focused their attention on the theme of nanoscience and nanotechnology and all issues that spin around.

Finally, what do we have now?

1. We have, on one hand, a notorious progress in nanoscience and nanotechnology which has been welcome, or reasonably recognized by the scientific community, industry and other players as well;
2. On the other hand, we have citizens adopting a position of scepticism, suspicion and fear towards the dissemination and communication of advances in nanoscience and nanotechnology;
3. We also have a third group which comprises people who have not yet formed a consolidated opinion. 

Regarding the first group, those have access to information published on scientific articles. This group is well informed, on a scientific and technological perspective.

In my opinion, it is impossible to isolate the responsible for the roots of nano-fear. The world and society are too complex and dynamic for such a task. However, it is possible to identify "clouds of higher probabilistic density" where responsibility for the roots of nano-fear is more likely to be located.

This article will try to decode the roots of nano-fear. Or rather, I will try to decode those which are the main roots of nano-fear (or at least some of them).


Nanotoxicity And Nanopollution

Populations are exposed to (1) naturally occurring nanoparticles present in the environment and to (2) nanoparticles produced by Humans during their work activity (e.g. into R&D laboratories, industrial facilities and surroundings).

In what concerns to nanoparticles produced by Humans present in products produced by Humans, these are normally nanoengineered nanoparticles (NENPs) or, in other words, engineered nanoparticles. NENPs are nanoparticles that have been specifically designed for a specific function (e.g. packaging coating, protection of radiation in sunscreens). 

In addition, Humans are exposed to a wide range of nanoparticles incorporated into consumer goods. As consumer goods, the waste is thrown into the trash and follows (seeing this process through an optimistic perspective) the entire cycle of garbage separation and subsequent treatment.

Therefore, nanoparticles are present in (1) the air, (2) the water and (3) the soils. Thus, all requirements for the entire biosphere is contaminated with the ubiquity of nanoparticles are gathered.

On the other hand, nanoparticles present into plants and animals traverse the entire food chain until reach Humans.


The Tremendously Enormous Complexity of Nanoregulation

In fact, nanoregulation is an intricate network of interconnected processes that require expertise and experience of many people currently working in an articulated, coordinated way, under the auspices of the positive and constructive debate, cooperation and collaboration. Nanoregulation is anything but easy. At a certain point and in many cases it is necessary to understand science, nanoscience, nanotechnology and legislation at the same time.

Explained the matter this way, it is not surprising that nanoregulation had begun to be developed with some delay. In my personal opinion, I believe that is extremely unfair to throw responsibilities to regulatory authorities. The nanoregulation is complex and complicated by nature and definition. I dare to state that nanoregulation is one of the aspects (or the aspect) of nanoscience and nanotechnology with greater complexity, higher degree of difficulty to be solved and that requires more resources.

Even then, the regulation started with some delay and that's a fact. The reasons, these I already explained above.

The consequence: fear ("what will happen to our world, our planet, we and the environment, if the authorities do not implement nanoregulation?").

Anyway, the regulation is currently (at least in some parts of the world) being developed at full speed. One among several examples, I have already presented in a previous article: "Good Winds From FDA".


Gaps (which will disappear) in Regulation

From what I've observed, most of the industries that operate totally or partially in the field of nanotechnology adopt a policy of transparency and good practices. Also from what I've seen, only a minority of industries has chosen the path of the lack of transparency, good practices, thus leading to poor credibility.

As I pointed above, nanoregulation is extremely complex.

Drugs that require medical prescription are, due to statutory requirements, introduced in the commercial channels after being approved on clinical trials. This principle applies to drugs that do not rely on nanotechnology, but also to nanotechnology-enabled drugs.

However, health care products (such as a lot of cosmetic products) do not require medical prescription and are not subject to legal requirement for clinical trials. This applies to products which do not use nanotechnology, but also those nanotechnology-enabled medical products.

Nanotechnology-enabled medical products contain (as it is understandable) nanoparticles. This is not necessarily bad. Rather, it can be highly advantageous. If clinical trials clearly show that the following requirements (with respect to nanoparticles of the drug) are met, then the nanotechnology-enabled drugs present an added benefit and are highly advantageous from the therapeutic point of view:

• Nanoparticles are not toxic to the patient;
• Nanoparticles are not toxic to the workers;
• Nanoparticles are not toxic to the environment;
• Nanoparticles actually contribute to increase the therapeutic efficacy of the drug.

Industries in general, even with an absence of regulation, choose the path of transparency to consumers - the right choice, that reveals responsibility and clear thinking and brings high benefits to the corporate credibility.

However, on the other hand, the absence of regulation for certain medical products creates opportunity for some industries (which I believe to be a minority) to adopt a posture less transparent to consumers.

Again, this absence of transparency to customers, once communicated to citizens (specially if the information is communicated by communication professionals who have a poor knowledge of what they are talking or writing about) produces fear and suspicion.

Intensive work is under development now in order to eliminate or minimize these regulatory gaps. I personally believe that the nanoregulatory landscape will change the rules within a relatively short time.


Nanoeducation

Nanoeducation has been undervalued. Today the perception of nanoeducation is wrong and dysfunctional. It is common practice to perceive nanoeducation as a set of academic programs (e.g. courses, degrees, masters, doctorates, post docs) directed to nanoscientists or other scientists interested in career advancement and enrich their curriculum vitae. This is in fact nanoeducation. More precisely, this is just a tiny part of nanoeducation (according to my personal way of thinking).

An excellent nanoeducation would complement and fill an enormous range of gaps in the entire nanotechnology framework – something that unfortunately does not happen.

A world population with a wrong, distorted or dysfunctional perception of nanotechnology and the benefits it can bring to society can trigger the decline of nanotechnology.

Bioethics, Nanoethics and Nanobioetichs / Bionanoethics. In One Word: Ethics

The vast majority of the promises that nanoscience and nanotechnology bring us, when evidence-based (in most cases); fill us with hope for a better life and better world.

However, there are a whole range of ethical issues that require serious debate, intensive and comprehensive, carried out by experts from various sectors. Many of these debates are already being carried out in a serious, intensive and comprehensive way, by experts from various sectors.

Follow some aspects that are the object of debate:

• Nanotoxicity and nanopollution. Although this issue has already been described above, it does have a serious ethical component;
• Bad practices carried out by a minority of industries in contrast to the good practices undertaken by most industries. Although this topic has also been identified above, has also a serious ethical component;
• Consumer protection. This point is raised by the existence of bad practices carried out by minority of manufacturers of consumer goods. As expected, this aspect also contributes to the nano-fear and suspicion;
• Nanomedicine, increased life expectancy, increasing world population, Human enhancement and sustainability. As evidence of many scientific papers published, nanomedicine offers tremendous potential for populations: (1) earlier and more accurately diagnostics of diseases; (2) more effective treatment of diseases; (3) more effective cure of diseases; (4) significantly increase of the welfare of the population; (5) significantly increase the life expectancy of human beings. Directly or indirectly, nanomedicine will help the populations having better health and living up later. This contribution reinforces the estimates of the global population growth and increased average life expectancy of populations. So here we all have a real and serious problem of sustainability for all our descendants. Human enhancement is the set of efforts, actions and technologies to overcome (temporarily or permanently) the current limitations of the human body employing natural or artificial means. The definition of "Human enhancement" is not very clear and there are divergences in relation to this matter. Some bioethicists and  nanobioethicists prefer to restrict this term to the non-therapeutic application of specific technologies to Human biology. Some examples: nanotechnology, gene technologies, neurotechnologies and cybertechnologies. This issue unleashes controversy about what is acceptable and what is not acceptable to do. The debate also discusses where must begin and where must end the Human Enhancement Technologies (HET). The debate involves ethical, bioethical, nanoethical, nanobioethical, anthropological, philosophical, religious aspects among many others;
• Applications of nanotechnology in defence. Just the mere mention of this aspect alone creates fear and suspicion. Applications can even serve only to make the equipment lighter, for example. However, fear and suspicion are emotional and therefore irrational feelings;
• Unauthorized access to nanotechnology by individuals or groups of individuals with bad intentions. We live in an era of innovation and reinvention. Developing this idea with some irony, even terrorist groups need to innovate and reinvent their methods of spreading terror;
• Theft of private health information. The development of nanotechnology applications is reflected in the development of nanoelectronics, the construction of new semiconductors, and computers with processing speed, storage capacity and number of functionalities incomparably more powerful of the ones currently used. This development paves the way to an enormous benefit: the development of management systems for health information, which will benefit not only patients but also all health systems. As happens today, there may be a risk of theft of private health information.

The Responsibility of Media Professionals

Regarding the second and third groups (on Introduction), people in general (the average citizen) are informed through the media:

• If the information is independent, accurate, accessible and of quality, people are well or acceptably informed;
• However, if the information is partial, speculative, unfounded, inaccurate, explained in a confusing way and of dubious quality, people get a distorted picture of reality. 

In my personal opinion, communication professionals are divided into two main groups:

• Those who are well informed or know the bare minimum about what the subject is about and, in this case, communicate seriously;
• Those who simply know nothing about it and due to their profession, treat the information with negligence and with a doubtful credibility;

Those communication professionals, who simply know nothing about nanoscience and nanotechnology (or even science) and due to their profession, treat the information with negligence and with a doubtful credibility are the ones who deliver partial, speculative, unfounded, inaccurate information. This bad information is also explained in a confusing way and is of dubious quality. Consequently, people start to have a distorted view of reality.

What are the direct consequences of this? Fear and suspicion.

Are those communication professionals who simply know nothing about nanoscience and nanotechnology (or even science) and treat the information with negligence and with a doubtful credibility the solely responsibles for the nano-fear? By no means.

Media professionals (in general) are simultaneously:

• The last link of a complex and dynamic chain of actors and processes, placed immediately before being triggered various discussions and an atmosphere of (1) acceptance, (2) indifference or (3) fear and suspicion;
• The most influential communication interface with the average citizen.

Final Comments

In this article I tried to decode the roots of nano-fear (or rather, those that seem to be the main roots of nano-fear or at least some of them).


As everything in Life, pointing out what is (or was) wrong (or has room for improvement) is not enough. It is also necessary to point out ways and solutions. This is what I will do in some of my next articles.

Good Winds From FDA

The U.S. Food and Drug Administration (FDA) published yesterday (April 9, 2012) in YouTube a video entitled "Innovation Pathway at FDA."

Personally I really like the video and especially the positive message it conveys. Here in my blog I give my Sincere Congratulations to the FDA by the video, and especially by the highly positive message it sends.

This message is a very strong set of clear positive signs of optimism, hope, constructive spirit, innovative spirit, proactive and highly dynamic attitude announced to the world.

As far as I know, FDA is among their counterparts around the world an entity with an unquestionable credibility and effectiveness. My perception is that FDA is the reference with respect to regulations in the areas it is responsible.

However, FDA has been discussed in the most recent years with destructive attacks and comments. For example:

• Apparently innocent criticism;
• Explicit accusations of not updating (or updating very slowly) its regulations when confronted with new challenges brought by an emerging new reality which includes the requirement for innovation and new and emerging sciences and technologies;
• Unfounded conspiracy theories which proliferate throughout the Internet;
• Sensationalist news trying to undermine the credibility of this organization.

Some of these attacks had eventually caused some abrasion on the image of FDA as an organization.

Therefore, FDA needed to launch a campaign containing a very strong message of positivism, optimism, hope and confidence addressed to the world.

The reality has changed in recent years. It is a fact that reality has changed and will change constantly. Thus, FDA and similar organizations must adapt to new realities, new paradigms and the requirements they entail.

But what really happened in the most recent years that really made ​​this change and therefore lead to attacks on FDA and similar organizations, and consequently the release of this video?

Several changes took place.

Firstly, the counterfeit medicinal products began to proliferate in practically the entire world. The counterfeit drugs have become a real scourge in terms of public health and a threat to the pharmaceutical industry.

Moreover, nanoscience and nanotechnology grew and developed at an impressive speed.

Similarly, nanomedicine grew and developed at a considerable speed. Nanomedicine gained critical mass and is proving to have potential to contribute constructively to improve medicine and biomedicine. This is just the beginning. Many more discoveries are to be announced and to a higher speed.

Likewise also grown and developed the applications of nanotechnology-based products in the food & beverages sector. This includes not only food, but also packaging and manufacturing processes.

With the fast development of nanotechnology with applications in medicine (nanomedicine) and in the food & beverages industry, have also emerged real risks associated with toxicity, both environmentally and in terms of public health. These risks are directly related to nanoengineered nanoparticles (nanoparticles intentionally modified by humans for the fulfilment of certain specific purposes). Scientific studies show that these nanoparticles (in opposition to naturally occurring nanoparticles) present the greatest risks to the environment and public health, with respect to toxicity.

Anyway, regulating with quality and adjusted to the real needs of today's society (especially regarding nanotechnology-based health products and food & beverages) is an enormous task, having a complexity of unique proportions. I would say, of historic proportions. It is a complicated challenge and only give good results if integrated, coordinated, standardized and implemented with much committed collaboration with different players, such as innovators, scientists, R&D institutions, universities, industries, health professionals, consultants, IT professionals and many more players.

It is notorious that the video puts much emphasis on technological innovation and collaboration. It is an extremely strong reinforcing of confidence message. In my opinion this message is fully justified, to calm down conspiracy theories and media sensationalism.

This version was published on April 11, 2012, since the original one was removed.

In these areas of science and technology, the worst that can happen is a lack of regulation, which causes a gray zone, providing opportunities to bad professional journalists to make pieces of questionable quality, thus generating fears, suspicions and unfounded conspiracy theories.

FDA is really working hard. I did not learn that with this video. I had already noticed with various press releases issued recently, mainly during the year of 2011 and during the current year. This video just confirmed what I already knew.

However, the ordinary citizen, who is not involved in these matters, did not know. Through this video, the ordinary citizen gets to know.

The tasks that FDA faces are of odd proportions and dimensions absolutely gigantic in the history of our civilization. I can only wish the greatest success to FDA and give them strength.
