We know chlorpyrifos harms kids. It’s time to act.

EPA is taking another look at chlorpyrifos, and it’s about time. Scientists have known for years that it's especially harmful to children’s developing brains — that's why it was banned from home use back in 2001.

But 8-10 million pounds are still applied every year in agricultural fields, putting rural children in harm's way and leaving residue on apples, broccoli, strawberries and many other crops. EPA's current review overlooks the strong science showing that this pesticide can be very, very damaging to children — even at extremely low levels.

Due to widespread public concern, the agency has extended the period for public comment on this review for an extra 60 days. Sign the petition below, and we'll deliver it before the comment period closes on May 7th. It’s time to protect our kids!

Re: Docket # EPA-HQ-OPP-2008-0850

Dear Deputy Administrator Perciasepe,

We are very pleased that EPA is evaluating the health risks of the widely used organophosphate insecticide, chlorpyrifos. We are concerned, however, that your current assessment is overlooking important science about the health harms this chemical poses to children.

The findings of the current assessment — that volatilization drift puts farmers, workers and neighbors at risk — provide strong evidence that the potential harms of this pesticide far outweigh any benefits it may provide.

Yet we believe the agency may be seriously underestimating risk, given the strong science linking chlorpyrifos exposure to children's health harms via biological mechanisms that are not even considered in your review.

In particular, we are concerned that EPA continues to limit its analysis of chlorpyrifos health harms to the chemical's acute effects on the nervous system enzyme, cholinesterase. This fails to recognize many other long-term effects on developing children’s nervous systems, such as effects on brain architecture from "in utero" exposure and thyroid effects linked to a range of developmental harms.

The scientific community has understood that chlorpyrifos exposure is harmful to children for many years, as is clearly shown by the 2001 ban of home uses of this chemical. And the scientific evidence continues to mount. It is time to protect all children from the harms of chlorpyrifos, and the agency should take swift action to do so.

This petition is no longer active.
