Engineers explore environmental concerns of nanotechnology http://apocadocs.com/s.pl?1265055160
History has shown that previous industrial revolutions, such as those involving asbestos and chloroflurocarbons, have had some serious environmental impacts. Might nanotechnology also pose a risk? ... Scientists and engineers at the center have outlined plans to conduct research on the possible environmental health impacts of nanomaterials. The plans include new approaches, such as creating a predictive toxicology model based on cell assays and building ecosystems to track nanoparticles.... In their preliminary studies, results indicate that "oxidation does impact solubility, as absorbance after resuspending in water is lower for fullerenes exposed to ozone." The implication is that reactions in the atmosphere can transform nanoparticles and make them more likely to dissolve in water once they deposit back to earth. There, they can travel farther and come in contact with more organisms than if they were stuck to soil.
