The government’s plan for research on potential health and
environmental risks posed by the use of nanomaterials has been bashed in the
latest report by the National Research Council, who found it to be faulty. As
nanomaterials begin expanding their use in consumer goods and the industry in
general, the need for a risk assessment, but also for public acceptance for
these emerging products, become mandatory.
The committee said the National Nanotechnology Initiative
document can ultimately be an effective tool for communicating the breadth of
federally supported research associated with developing a comprehensive
understanding of the implications of nanotechnology, however, in its present
form, it lacks essential elements for the complete understanding of
nanomaterials’ health and safety impact.
The report clearly states that the government plan does not
describe a strategy for nano-risk research, it lacks input from a diverse stakeholder
group, it also lacks vision and a clear set of objectives, a
comprehensive assessment of the state of the science, a plan or roadmap on how
research progress will be measured, and the estimated resources required to
conduct such research.
Although admitting to finding a lot of specific topics on which
more research is needed to address environmental, health and safety issues, the
committee also found that although the research needs are sufficient for some
research categories, they are poorly defined and incomplete in others,
specifically risk management and exposure assessment.
Furthermore, the report also reveals that the governmental strategy
document does not present concrete research notes, measurable objectives, and
that the implementation plan fails any sense of how success toward specific
goals will be measured or what resources might be needed to achieve them.
As Committee chair David Eaton, professor of environmental and
occupational health sciences, School of Public Health, and associate vice
provost for research at the University of Washington, Seattle, explained, the
plan catalogs nano-risk research across several federal agencies, but it does
not present an overarching research strategy needed to gain public acceptance
and realize the promise of technology.
Nanotechnology deals with atomic and molecular scale
materials, under 100 nanometers, and has the potential to be used in a wide
range of domains, from medicine, to electronics, to energy production and more.
Products using nanomaterials are already available on the
market today, in health and fitness products mostly, such as skin care and
cosmetics, but their number and applicability are expected to grow
significantly within the next few years.
But despite their usefulness and increasing popularity,
there are also concerns over their impact on human health, but also on the
environment. Specialists warned that nanoparticles created lung and brain
damage in mice, and that some nanoparticles could destroy beneficial bacteria
important for breaking down organic matter in waste treatment plants of farms.
