The Environmental Protection Agency issued comments regarding the journal Pediatrics study that concluded that "organophosphate exposure, at levels common among U.S. children, may contribute to ADHD presence."


EPA said its taking this study very seriously and is incorporating its findings in EPA's ongoing evaluation of the organophosphate pesticides, along with additional health data. EPA has completed a comprehensive reevaluation of all the organophosphate pesticides, and one of the outcomes of this process was the elimination of nearly all residential uses of organophosphate pesticides as well as some food uses to reduce risks to children. Data used in the Pediatrics study, from 2000-2004, would have been generated while these OP uses were being phased out and, thus, would not have reflected the new restrictions imposed by EPA.


Overall, EPA agrees with the authors' conclusion that the data do not currently prove that organophosphates cause ADHD and that there are limitations in the organophosphate exposure assessment through the use of a single metabolite from a single spot urine sample.
