By Porter Wright on The NanoSafety Consortium for Carbon just submitted a proposed toxicity testing agreement to EPA under Section 4 of the Toxic Substances Control Act covering a range of nanoscale materials including multi-walled carbon nanotubes, double-walled carbon nanotubes, single-walled carbon nanotubes, and graphene. Key elements for the curious: The chemical substances to be tested … Continue Reading

By Porter Wright on Last Friday, EPA’s Office of Research and Development announced in the Federal Register a 45 day comment period for its new draft case study on the use of nanoscale TiO2 in water and sunscreens: "Nanomaterial Case Studies: Nanoscale Titanium Dioxide in Water Treatment and in Topical Sunscreen" FR 74,146 at 38188 (July 31, 2009). The report … Continue Reading
By Porter Wright on A recent paper published in Inhalation Toxicology suggests that reliance on ultrafine particle inhalation animal studies for nanoparticle health and safety purposes may be appropriate due to the lack of existing studies on nanoengineered particles. The article referenced several existing health and safety studies concerning nanoparticles, and noted their sometimes differing and conflicting conclusions. Specifically, the … Continue Reading
