The
environmental impacts of nanotechnology techniques (in English:
environmental implications of nanotechnology) in that the potential for
the use of materials and hardware techniques for minor effects on the
environment. Considering
that the field of nanotechnology techniques is a newly arising field,
it has spread discussion and debate about the extent to which he has
been the industrial and commercial use of the materials minor impact on
living organisms and ecosystems. And it can be divided into the environmental impacts of nanotechnology
techniques into two: the possibility to take advantage of technical
innovations in miniature to help improve the environment, and the new
type of pollution caused by nanotechnology techniques in the case of
materials emitted to the environment.The
pollution-year term nanotechnology techniques and comprehensive for
each waste resulting from the use of micro-technical or during the
manufacturing process materials nanotechnology techniques devices. That waste may be considered a high degree of risk, due to their size. Where you can float in the air may easily animal and plant cells, thereby causing penetrate the unknown effects of each. Most
of the particles trivial things man-made invisible in nature, and thus
may not have the organisms and liquid appropriate to deal with these
mini waste. Perhaps one of the huge challenges facing the nanotechnology
techniques is: how to deal with pollutants and waste nanotechnology
techniques.The
environmental assessment process is justified on the grounds that the
particles minor range of modern environmental impacts. Scrinez
and raises concerns about the pollution caused by minor techniques, and
explains that it is not possible at the present time that "are
accurately predict or even control the environmental impacts of the
emission of waste that technology in the environment." The
environmental impacts are still toxic molecules nanotechnology and
bio-accumulation factories and micro-organisms in question. Also
it raised particles minor's ability to operate as a mechanism tanker
anxiety and concern about the process of heavy metals and other
environmental contaminants transfer. According
to the May 2007 report by the UK Department for Environment, Food and
Rural Affairs Commission has expressed concern over the environmental
impacts of toxic molecules trivial things for each of the risk and
spread. The report recommended a thorough examination and testing to
environmental toxins as well as to conduct independent tests as well as
for fuel additives.Noting
the lack of sufficient information enables us to make sure whether the
particles minor negative undesirable effects on the environment. We
find here two points linked to that case taken: in: (1) nanotechnology
free particles emitted into the air or water during the production
process (or production) accidents or emitted as waste from the
production process and then accumulate in the soil, water and plant
life. (2)
In the fixed condition, when it is a part of manufactured articles or
final product, then it must be recycled or disposed of as waste. It is still not known to us whether the particles will be trivial things a new class of non-biodegradable pollutants fully. In the case that this is done, it is not known as well as how to get
rid of these contaminants and remove them from the air or water because
of that traditional filters inappropriate to perform such tasks (as the
very large pores to be able to catch the particles to be ejected trivial
things).And
the share of funding that was spent in 2002 on environmental impact
assessments from within the total amount of 710 million US dollars the
US government by spending on technology research trivial things about US
$ 500,000. Risks
identified Ooscokovic which included (2007) as follows: self-repetition
of Nanobut strongly that through increased expansion and slowly lead to
a full erase biosphere; in addition to the further destabilization of
the biosphere diversity at risk already increased the gap between rich
and poor. and it has been increasing concern over the silver nanoparticles and
used by Samsung in many household appliances such as washing machines
and air purifiers.Responsibility for the life cycle
To
assess the health risks of nanotechnology particles manufactured, must
assess the full life cycle of these particles, including the
manufacturing process, storage and distribution as well as application
and ill-use and disposal as well. The effects on humans and the environment may vary and change during the many stages of their life cycle.And
may select the Royal Society report particles emitted or tubes minor
risk during the disposal process or destroyed and recycled. The
report also recommended that "manufacturers of various products that
fall under extended producer responsibility regimes such as end-of-life
legislation, publish procedures that summarize how to deal with such
material as well as to reduce the chances of human and environmental
exposure," p. 13. In
a move of the Institute for Food and Agricultural Standards reflects
the challenges that ensure the organization of the life cycle, the
proposal need to integrate search criteria and developing technology
that nanotechnology within the consumer and the worker and environmental
standards. It also suggested that both the non-governmental organizations and
other civil groups play an essential role in the development of those
standards.
And the effects of nanotechnology torrent of human and medical,
ethical and psychological, legal and environmental applications, and
associated with many fields, including engineering, biology, chemistry,
computing, materials science, and military applications, and
communications, but that its impact incalculable.And
it includes the benefits of nanotechnology to improve manufacturing
techniques, and water purification systems, power grids, and promote
physical health, nano-medicine, and improve methods of food production
and feeding on a large scale and infrastructure for the automotive
industry. Products made with nanotechnology may require a bit of work, and the
earth, or maintenance, and be of high productivity, low cost, and have
modest requirements for materials and energy.However,
the risk may be linked to both the environmental and health fields, and
safety issues and the negative effects of micro-particles that are
studied before being released; transitional effects such as displacement
of traditional industries and products of nanotechnology has become
dominant; military applications such as biological weapons, and
monitoring through sensors nano , and of concern to defenders of privacy rights.There
is debate about whether the subject of a special technique of
nano-governmental organizations is, and regulatory agencies, the US
Environmental Protection agency and the Health Directorate of the
European Commission and that the consumer has begun to deal with the
potential of this controversial technical risk and protect. It is worth mentioning that the Arab world lacks these institutions. As the organic food sector a head start in dealing with the systematic
exclusion of nano particles Jsaat of organic production process approved
in both Australia and the UK
The
rapid development of nanotechnology applications in many fields, and
the corresponding significant lack of knowledge of the implications of
this, calls for a lot of caution. Nano materials
industry is a fast-growing industry, both in terms of the total size or
terms of the number knowledge of the potential health
and environmental risks of nanotechnology are almost rare. This also applies to how it affects the human who does not doubt that he will be more prone to micro-nano materials.
Although
there is enough evidence to suggest that the development and use of nano materials brings risks to health and the environment. However, studies in this area is still very slim. Rapid
evolution in nanotechnology unfortunately offset by a significant lack
of information on the extent of the risk of their use. It is the results of initial tests of the impact of nano-materials on
animals indicate that inhalation of nano particles kills the animal and
this indicates which leaves no doubt on the harmful effects on human
health.
The urgent need for more research on the dangers of nanotechnology:There
is not enough information about the environmental impacts of nano materials, and the effects absorbed by living organisms, and the
effect of accumulation within the body of the organism. Moreover, the development of methods for the detection of nano materials in the environment will be a major technical challenge. Is likely to be the most important childhood respiratory routes of
exposure to micro-materials, it has mainly been research in this area.
Experience
at the University of Rochester have been conducted on rats inhaled nano particles It later turned out that the nano-particles lodged in the
brain and lungs, leading to health complications that nano particles will be able to spread to other parts of the body. However, the knowledge about the harmful effects of it is very limited. Also
studied the effect of nano particles on the airways, and the factors
that affect them end up like molecules properties (composition, size and leach ability), and the impact of the formation of the airways and the
impact of differences Alferd ihvi breathing patterns. Next
to that a few of the studies conducted cared absorbing nano materials
through the digestive tract, and these studies show that most nano materials that are entered in the digestive tract, quickly disappear
from there. In
addition to other studies focused on absorbing nano materials through
the skin, which may be an important window for the absorption of nano particles, but the underlying mechanisms behind it are still not small micro can reflect the different membranes of cells, for
example, it has been found yet to penetrate the skin in the mitochondria and the nucleus of the cell. This information may be of paramount importance for the toxicity of nano materials.
Other
studies suggest that some nano materials can be absorbed by biological
tissue, but it is not possible to draw any general conclusions about the
tendency of nano materials on the accumulation biology
conducted indicate that there is an urgent need for new tools to
understand and appreciate the size of the exposure and determine the
doses. But there is also no information about the availability of these tools at the present time. And
it increases it complicated that you can not devise the impact of
nano-particles to study materials on a wider range of materials in the
nanometer size range. General assumptions can not be for all nano-materials nano materials regarding how to deal with situation.
The absorption is intended to nano materials can be made through inhalation, or through the mouth, or through the skin. And through the eye and the other ways also we can envisage in the future. Inhalation
and is currently considered the most important by exposure to fine
particulates, and the shrine of the first search at the present time. There are a few studies on the environmental poisoning nano materials. Therefore,
it is not possible to draw any general conclusions about whether nano materials pose a significant threat to the environment or not. There
is a fundamental problem in the evaluation of exposure to nano particles
estimates and are not specific because of a lack of information. The studies on the toxicity of nano materials is relatively limited.
Hack into your body without your permission:The
impact of nano materials to human health as a significant risk that nano particles are able to enter the human body very easily through the
pores and without any resistance and can spread within the body which
cause health damage to humans. You
can imagine that the particle size of 300 NM can enter with ease in the
human body cells and that the particle size of 70 NM can enter with
ease in the nucleus of the cell and this shows the great danger that can
be exposed human has the interaction between the nano particles and
cells of the human body happen leading to cell properties or poisoned her death and change.
Risks of nanotechnology .. international outlook:The complexity of the global environment and health organizations in
conferences all over the world to discuss the risks that may result from
the use of this technique was the first global meeting was organized to
discuss nanotechnology damage in Brussels.
The
organization published a Green world peace recent statement indicated
that they would not call for a ban on nanotechnology research. Pointing
out that the human today is on the threshold of a new era in all
respects should not generally stand for this development but called to
try to reduce the negatives as much as possible. in nano-size can of her sneak behind the immune system in the
human body and can also sneak through the membrane skin and lung cells
and that it can go beyond the blood brain barrier.
Oxford
University study showed that nano-titanium dioxide found in ointments
anti-sun hit the molecules of DNA damage to the skin. A study of the Johnson Space Center and NASA have shown that carbon nano tubes are more harmful than quartz dust that causes a fatal disease
Alsellakoshis gets in the workplace.
Recent
developments in the nanotechnology It turns out that was developed
socks containing Nano Silver particles prevent the smell of feet but it
turns out to have serious consequences on the human body. These bacterial molecules and is able to kill the task beneficial
bacteria break down organic material in the waste treatment plants or
farms.
As
between Seton Anthony from the Institute of Medicine in Edinburgh
(Scotland) in the study finally published the nanometer carbon nanotube,
which is technological revolution unprecedented may be harmful and
deadly organisms, including humans so must be dealt with this science
very carefully demanded the exclusion of Food and Agriculture of this technological development in order to preserve human beings. It
is well known that if the absorption of nanoparticles through the roots
of plants and trees or through the air, it will inevitably lead to
humans and animals through food. Herein lies the danger, especially if these molecules contained through the stages of processing harmful substances. Whatever the case is, the nanotechnology is important, but before that
we develop Let Us in the negative effects of which will provide
technical reconciled with the environment.
She
foreign studies that nanotechnology has attracted multi its
applications attention of both groups, scientists, businessmen and
governments of developed countries alike, when they saw the new
industrial revolution that will lead to changing the way that commends
them most of the material and produce the most products, including
reducing the raw materials needed for production and energy, and increases the
efficiency of the products, and the properties were not earned by her,
which would result in increasing the value of things.While
recognizing that they present and future technology, the question about
the extent of its impact on the health and lives of human beings and
the environment also continues to exist? Where controversy arises about the possibility of containment of
materials and products created by those promising technology on the high
degree of toxicity, which is alarming and represents a serious
challenge to the environment.In
spite of the potential negative effects of the products manufactured in
this promising technology on human health are still unknown and growing
to a large extent, despite all safety procedures are followed, the
hundreds of them markets may submerge already in all areas of clothing
to medicine to pulp teeth cleaning and whitening to roads food and materials to maintain the vitality and beauty and fitness ..
etc, and research and experiments and production processes carried out
in full swing to produce more of them still.It
could be argued that the human addresses many of these manufactured
goods from nanotechnology with its food and drink, they are carried out
to the body through the pores of the skin through cosmetics and a number
of oils and creams, especially species used for protection from UV and
custom anti-wrinkle, along with a number of cleaning materials private dental species used for bleaching, which arises doubts about
the possibility of its creation to scratches gum and reduce tooth
thickness, as well as the water that washes or rinses out and swimming
pools represent the wounds and scars and cracks and Inayat skin more
positions to the permeability of hazardous substances to the body.So we have to recognize the benefits gained and the negative effects
of this new technological revolution and the changes that Sthdtha our
lives to reap the fruit and avoid or minimize disadvantages and to be
sure that it will not Tzmna at the same time.
Scientists
also warned at the University of Hai from the inability to identify the
impact of dark colors carried by particles micro outstanding water and
air and the extent of their authorities to use and its impact on plant
photosynthesis, scientists have expressed more concern about the
increased potential for health risks, and raised many questions about
the speed the reaction of molecules of different materials when smaller to the
nanometer scale, as well as pollution caused by soaring rates of
absorption of that minute, where behave mini elements of the size of the
nanometer, due to the small extreme size and area of the large
particles, attitude different from the typically reported in its normal
size.Most
of the research addressed the larger particles, and went out the
results emphasize the need for a scientific approach to monitor and
address or mitigate the high degree of toxicity of pollutants, there is
an urgent need to determine the composition of heavy metals such as
cadmium, mercury and arsenic particles in the air, and the traditional
technologies are often not sufficient to reduce concentrations of these toxic elements in the waste water to acceptable levels.Growing concernAlthough
it is not yet the case of one poisoning materials engineered
nanotechnology monitors, there is growing concern among researchers
about the toxic substances carried by particles finite, and their
ability to penetrate the cell walls and effect with the current
circulation and penetration of the membranes of brain, which protects
the brain from vulnerability to harmful chemical substances that carried in the blood.More
and the relevant science toxins studies anxiety, and about the ways in
which these materials can enter the body, especially to the most likely
and dangerous is the way inhalation Human them with air, and they
penetrate the respiratory system to settle all part of his lungs,
leaving interactions more dangerous than carbon black particles or quartz, as well as that of the hard particles that exposure to
hazardous substances for long periods (normal or nanometer size)
increases the likelihood of exposure to lung cancer and heart disease
significantly.For
his part, Vicki Colvin, director "nanotechnology, biological and
environmental technology" center at Rice University more concern
expressed about the adverse effects of the particles of inorganic and
other consequences of Nano materials to public health since the
Industrial Revolution, and said that more areas of concern currently
fields is the impact Particle
micro on the lungs, and the possibility of leakage unwanted body during
surgical operations, as will switch their ability to penetrate human
cells and which is seen as one of the most prominent achievements of
applications Nanotechnology in medical science to reverse intended to,
and become detrimental effect if they operate outside the scope of control, and so there is an urgent need to discover new ways
completely to identify whether these materials will interact with the
human body which invaded by force or remain inactive and measure the
extent of this interaction and monitor the results and continues to
discover new means and tools opportunities to measure this interaction
and determine the degree of toxicity open.For
this and what is more, many of the opposition and civil groups of
genetic engineering and directed worldwide efforts to urge scientists
with an interest in research and applications of nanotechnology to
explore the potential impacts of these promising and technical risks,
and to carry out their responsibilities due in this regard, and the
preservation of agricultural soil Association issued decision to ban the use of nanotechnology in the field of agriculture
and the granting of certificates bearing the first sign of the world's
benefit is established by the free agricultural product issued to him
these certificates from nanotechnology, which is now used on a large
scale in the United Kingdom, it carried about 80% of the bio-agriculture
products there
