US EPA extends comment on chlorpyrifos risks
The US EPA has extended the comment period on its revised human health risk assessment for the organophosphate insecticide, chlorpyrifos, by 45 days to April 30th. The Agency agreed to the extension due to the complexity and length of the risk assessment. The EPA is considering the imposition of further restrictions on chlorpyrifos to ensure that workers who use or work around areas treated with the insecticide are protected and that drinking water sources are protected. It issued the revised human health risk assessment in January.
