«Our study found more recent exposures were more important for mortality risk than historic exposures, but we
need to do more work on how air pollution affects health
over a person's
entire lifetime.
Maynard et al. say nanotechnology
needs to: develop instruments to assess exposure to engineered nanomaterials in air and water within next 3 - 10 years; create and test ways of evaluating the toxicity of nanomaterials in 5 - 15 years; generate models to predict their possible impact on the environment and human health
over the next 10 years; develop ways to assess the health and environmental impact of nanomaterials
over their
entire lifetime, within 5 years; and, enable risk - focused research into nanomaterials, within the next 12 months.
