Nanoparticles arent necessarily safe or dangerous, he said, You have to know what their constituents are. Their toxicity is influenced by their size, chemical composition, shape, surface structure, surface charge, solubility, how they aggregate and the presence of other chemicals. A multitude of factors need to be taken into consideration when assessing the safety and impacts of nanoparticles, and they need to be studied in complex realistic environments over time to accurately predict their effects. For the next five years, the Center for the Environmental Implications of Nanotechnology will look at how nanomaterials are transferred between organisms, how they bioaccumulate in food webs, the interaction between nanoparticles and environmental contaminants, and the impact of low-dose and long-term exposure to nanoparticles on ecosystems.
