The International Center for Technology Assessment (CTA) and a coalition of consumer, health, and environmental groups today filed a legal petition with the Environmental Protection Agency (EPA), demanding the agency use its pesticide regulation authority to stop the sale of numerous consumer products now using nanosized versions of silver. The legal action is the first challenge to EPA's failure to regulate nanomaterials. The petition and supporting documents are available at: http://www.nanoaction.org/detail/news.cfm?news_id=205&id=244 Jaydee Hanson, NanoAction.org A Project of the International Center for Technology Assessment.

Our focus is nanoscale silver, titanium, zinc and carbonaceous materials. We are in the process of preparing several manuscripts currently and have given several talks, including a recent talk at SETAC - Europe as a keynote speaker. In addition to lab research we are monitoring full-scale WWTPs across the US. For example, this week we are evaluating the change in titanium dioxide across each process in a full-scale WWTP. We have developed analytical techniques to differentiate engineered from natural titanium in biosolids. Biosolids contain approximately 2 mgTi/kg dry biosolids. Liquid effluents contain 0.1 to 3 ugTi/L. Feel free to contact me for additional information.
