Ten years and counting. That’s how long EPA has been trying to gather the most basic information on nanoscale materials in commerce. And that’s how long the nanotech industry has been throwing up roadblocks – despite its rhetoric that it supports EPA’s effort, which it sees (in theory) as a means to “favorably and efficiently address unwarranted concerns that have been raised” about the products of nanotechnology. This “say-one-thing, do-another” approach is both unfortunate and ironic, given that it has stymied getting to a well-informed government oversight system for nanotechnology that the industry should recognize is in its own best interest.
The latest round comes in the wake of EPA’s proposal of a reporting rule under the Toxic Substances Control Act (TSCA) that would call on makers and processors of nanoscale materials – those in the size range of 1-100 nanometers (nm) – to provide the agency with information relating to the materials’ manufacture, processing and use, as well as available data relevant to understanding their potential exposures and health or environmental impacts. Here’s EPA’s succinct summary of the rationale for the rule:
Nanoscale materials have special properties related to their small size such as greater strength and lighter weight, however, they may take on different properties than their conventionally-sized counterpart. The proposal is not intended to conclude that nanoscale materials will cause harm to human health or the environment; Rather, EPA would use the information gathered to determine if any further action under the Toxic Substances Control Act (TSCA), including additional information collection, is needed.
Despite this modest, common-sense objective, the proposal was met with vociferous opposition from the nanotech industry. Read More
