On August 13, 2010, the U.S. Environmental Protection Agency (EPA) announced that it is proposing to register conditionally a pesticide product containing nanosilver as a new active ingredient for a period of four years. According to EPA, the antimicrobial pesticide product, HeiQ AGS-20, is a silver-based product that is proposed for use as a preservative for textiles. As a condition of registration, EPA is proposing to require additional product chemistry, toxicology, exposure, and environmental data. EPA states that it will “evaluate these data as they are submitted during the period of the conditional registration to confirm the product will not cause unreasonable adverse effects to human health and the environment.” Under EPA’s new policy concerning public involvement in registration decisions, EPA is providing a 30-day opportunity for public comments on the proposed registration. Public comments will be accepted until September 11, 2010.
