At its most recent meeting a few weeks ago, the US Technical Advisory Group (TAG) to the International Standards Organization (ISO) Technical Committee on Nanotechnologies approved a motion to have ISO develop a Technical Report based on the EDF-Dupont Nano Risk Framework (NRF). Or to put it another way in acronym-laden Washington-speak, the US TAG to the ANSI-accredited ISO TC229 approved a TR based on the EDF-DD NRF. Read More

The insurance industry is out in front on nanotechnology yet again. As the giant reinsurer Swiss Re did way back in May 2004 with its groundbreaking report Nanotechnology: Small matter, many unknowns, it is once again the insurance industry sounding an early alarm about nanomaterials. In this case, it’s the Continental Western Insurance Group (CWG), which has just announced that it will exclude coverage for “the, as of yet, unknown and unknowable risks created by the products and processes that involve nanotubes.” Read More

I have just finished reading yet another depressing/infuriating publication by the Woodrow Wilson Center’s Project on Emerging Nanotechnologies. The new report delineates the many limitations faced by the Consumer Product Safety Commission (CPSC) in addressing nanotechnology health risks. The law governing the CPSC has significant weaknesses that prevent it from meeting critical needs, such as constraints on the ability to collect data, require reporting of known hazards, order recalls and promulgate mandatory safety standards.

EDF’s recent news release that gave a less-than-glowing review to the performance of EPA’s Nanoscale Materials Stewardship Program (NMSP) engendered a critique from Michael Heintz of Porter & Wright, accusing us of being “irresponsible” and potentially “sector damaging.” Our release had lamented the mediocre level of participation and lack of transparency surrounding the NMSP. I’ve posted a reply to Michael’s post, but also want to post it here. Read More

A growing number of observers of nanotechnology policy in the U.S. – at least those outside the U.S. government! – recognize that the Toxic Substances Control Act (TSCA) is poorly suited both to spur the generation of sufficient information about nanomaterials, and to ensure that information indicating potential risks will trigger meaningful action. So why not just tweak TSCA to make it work better for nano? Read More

Andrew Maynard, of the Project on Emerging Nanotechnologies, recently blogged about an Australian study that documented an odd effect of sunscreens containing nanoscale titanium dioxide (TiO2). The study was prompted by the observation that installers of metal roofs who used these sunscreens inadvertently transferred the product onto the roofs. In places where the workers’ skin had touched the painted metal surfaces, the paint showed accelerated weathering. Why? Because the particular type of nanoscale TiO2 in the sunscreen (the anatase crystal form) is photoactive – when it absorbs UV light, it releases free radicals that speed up the oxidation of the underlying paint.
