In 2015, EPA scientists recommended banning all uses of the insecticide, chlorpyrifos, on crops, because of the risks to the IQ of children.  However, EPA leadership did not sign off on the ban.  Leonardo Trasande, MD, MPP, explains the evidence of hazard for chlorpyrifos, as well as the economic cost to the nation from lost IQ due to chlorpyrifos and related insecticides.   Although chlorpyrifos was finally banned earlier this year, this case reminds us of the need to act when the science is solid, even if—and especially if—policymakers dismiss the science.
