EPA regulation of industrial nanomaterials: the good and the bad

Regarding EPA regulation of industrial nanomaterials ... let's take the good with the bad, shall we?

GOOD NEWS: According to Jim Alwood of EPA, its industrial chemical regulatory program (TSCA) has "regulated nearly all nanoengineered chemicals that it has reviewed" (as opposed to 10-15% of conventional chemistry submissions).

BAD NEWS: It takes 2-4x longer than a conventional review. 

GOOD NEWS: EPA has allowed most of the 160+ nano PMNs it has reviewed into the marketplace.

BAD NEWS: Beneficial uses are being delayed entry into the marketplace. perhaps due to EPA's conservative overestimate of risk when sufficient data is not submitted.
