FUEL ADDITIVE COULD OFFER FIRST-TIME AIR ACT TEST FOR NANOTECHNOLOGY

An effort by a nanotechnology company to seek EPA approval to market an engineered nanomaterial that is believed to improve diesel fuel economy and reduce emissions may be a first test of how the Clean Air Act (CAA) applies to engineered nanomaterials, observers say. Because the materials are eventually dispersed in engine exhaust, the effort could also serve as an early test of EPA's response to "dispersive" uses of engineered nanomaterials, rather than as part of "captive" structures which currently...
