On July 6, 2012, the U.S. Environmental Protection Agency (EPA) announced the establishment of a registration review docket for nanosilver. EPA states that registration review is its “periodic review of pesticide registrations to ensure that each pesticide continues to satisfy the statutory standard for registration, that is, the pesticide can perform its intended function without unreasonable adverse effects on human health or the environment.” Registration review dockets include information intended to assist the public in understanding the types of information and issues that EPA may consider during the course of registration reviews. According to the preliminary work plan, EPA has information that there are silver-based pesticide products that were registered without the registrant disclosing to EPA the presence or characteristics of the nanosilver in their products. EPA sent a letter in August 2009 to each registrant with silver-based products requesting a statement as to whether their products contained any amount of silver in any form having a dimension that measures between 1 and approximately 100 nanometers. Four registrants responded that their products, which were registered using data for conventional silver, contain nanosilver. In the preliminary work plan, EPA states it is identifying several other products, registered using data for silver chloride, as potentially containing nanosilver. The registration review for nanosilver includes these products, as well as the two HeiQ nanosilver products conditionally registered in December 2011. According to the preliminary work plan, EPA believes that additional data are needed to determine whether the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) standard for maintaining these registrations is met “due to nanosilver’s unique physical and chemical properties, and thus nanosilver’s potentially different health and safety properties as compared to silver.”
