Abstract-This study aims to give general idea about the risks of nanotechnology
There are lots of commercial uses in Nanotechnology.It has
an important roles in our lives and it will exponentially have a
significance in our future life. As this technology is used and
developed, we must understand any potential risks to human
health, safety and the environment. In this work, I want to
point out some risks about this developing area.
Nanotechnology is expected to be the basis of many of the
main technological innovations of the 21st century. Research
and development in this field is growing rapidly throughout
the world. [1]It is a broad and complex field of research and
manufacturing with many discrete decision-points. For
example, some decisions might be based upon an ability to
predict which nanomaterials will have favorable chemical
characteristics and lower toxicities, to identify important
knowledge and technology gaps, and to develop effective
communication with stakeholders and the general public [2].
Nanoparticles include carbon nanotubes, metal nanowires,
semiconductor quantum dots and other nanoparticles produced
from a huge variety of substances. Responsible development
of any new materials requires that risks to health and the
general environment associated with the development,
production, use and disposal of these materials are addressed.
This is necessary to protect workers involved in production
and use of these materials, the public and the ecosystem.
However, it also helps inform the public debate about the
development of these new, potentially beneficial, materials.
Assessment of health risks arising from exposure to
chemicals or other substances, requires understanding of the
intrinsic toxicity of the substance, the levels of exposure (by
inhalation, by ingestion or through the skin) that may occur
and any relationship between exposure and health effects [1].
Toxicity depends on dose and administration, even table salt
is toxic in high doses [3]. Fact is, that every new technology is
inherently risky - plenty of people are being injured or killed
every year by electricity, cars, chemicals, or nuclear energy,
just to name a few. In order to reap the benefits of a new
technology and make it acceptable to society there has to be a
general perception that the risks are fully understood, can be
managed and it is clear who is responsible for what. All of that
is currently missing in nanotechnology. Although the speed
and scope of nanotechnology risk research - and the emerging
field of nanotoxicology - is picking up, a lot of this work is
stand-alone research that is not being coordinated within a
larger framework [4].
