On February 9, 2012, the U.S. Environmental Protection Agency (EPA) posted a summary report on its January 2011 workshop on nanoscale silver. The workshop was the second in a series conducted by the National Center for Environmental Assessment (NCEA) to further the development of a research strategy for completing comprehensive environmental assessments of nanomaterials.  The basis of the workshop was the report Nanomaterial Case Study:  Nanoscale Silver...

The U.S. Environmental Protection Agency (EPA) has announced that, in response to public comments, it will provide the public more time to comment on the December 28, 2011, proposed significant new use rules (SNUR) for 17 chemical substances that were the subject of premanufacture notices (PMN). Of particular interest, seven of the PMN substances’ reported chemical names include the term “carbon nanotube” (CNT) or “CNT.” EPA states “the comment period is being...

On January 26, 2012, the Natural Resources Defense Council (NRDC) filed a lawsuit in the U.S. Court of Appeals for the Ninth Circuit against the U.S. Environmental Protection Agency (EPA) concerning its conditional registration of a pesticide product containing nanosilver as a new active ingredient for use as a preservative for textiles.  NRDC states that it seeks to limit public exposure to the nanosilver’s use in clothing, baby blankets, and other textiles. On December 1, 2011, EPA...

On January 25, 2012, the National Research Council (NRC) posted the pre-publication version of its report entitled A Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials. The U.S. Environmental Protection Agency (EPA) asked NRC to perform an independent study to develop and monitor the implementation of an integrated research strategy to address the environmental, health, and safety (EHS) aspects of engineered nanomaterials (ENM). NRC...

On December 30, 2011, the U.S. Environmental Protection Agency (EPA) Office of Inspector General (OIG) released a report entitled EPA Needs to Manage Nanomaterial Risks More Effectively. According to OIG, the purpose of its review was to determine how effectively EPA is managing the human health and environmental risks of nanomaterials. OIG states that it found “that EPA does not currently have sufficient information or processes to effectively manage the human health and...

The U.S. Environmental Protection Agency (EPA) published on December 28, 2011, proposed significant new use rules (SNUR) for 17 chemical substances that were the subject of premanufacture notices (PMN). Of particular interest, seven of the PMN substances’ reported chemical names include the term “carbon nanotube” (CNT) or “CNT.”  EPA states that because of a lack of established nomenclature for CNTs, the Toxic Substances Control Act (TSCA) Inventory names for CNTs are...

On December 7, 2011, the National Institute for Occupational Safety and Health (NIOSH) posted an item on its Science Blog entitled “Respiratory Protection for Workers Handling Engineered Nanoparticles.” The purpose of the blog item is to provide an update on the science and rationale behind NIOSH’s recommendations for the use and selection of respirators against engineered nanoparticles. The article summarizes respirator performance research and respirator...

The U.S. Environmental Protection Agency (EPA) announced on December 1, 2011, that it is conditionally registering a pesticide product containing nanosilver as a new active ingredient. HeiQ AGS-20 is a silver-based antimicrobial pesticide product approved for use as a preservative for textiles.  The final registration is not yet in the docket.  We believe, but cannot confirm, the final registration is largely similar to the draft proposed registration issued last year. As...

The U.S. Environmental Protection Agency (EPA) published in an October 26, 2011, Federal Register notice its final 2010 Effluent Guidelines Program Plan, which includes a request for comment and information for its 2011 annual reviews. EPA requests information on a number of topics, including discharges of nanosilver from industrial manufacturing. EPA cites nanosilver’s use as an active pesticide ingredient, an antimicrobial in fabric; a preservative in textile products,...

The U.S. Environmental Protection Agency (EPA) posted a September 2011 guidance document entitled Guidance to Facilitate Decisions for Sustainable Nanotechnology, which was prepared by the National Risk Management Research Laboratory of the Office of Research and Development. EPA states that it developed the guidance to assist in assessing the sustainability of nanoproducts, and it is intended “to lay the groundwork for developing a decision-support framework through continual updates as...
