California is banning a widely used pesticide that has been linked to brain damage in children, a major victory for public health advocates who have long fought to outlaw the toxic chemical in the agricultural industry.

The state ban on chlorpyrifos, a pesticide used on almonds, citrus, cotton, grapes, walnuts and other crops, follows years of research finding the chemical causes serious health effects in children, including impaired brain and neurological development. The US Environmental Protection Agency (EPA) had moved to ban the chemical under Barack Obama, but the Trump administration reversed that effort, rejecting the scientific conclusions of its own government experts.

“Countless people have suffered as a result of this chemical,” the California EPA secretary, Jared Blumenfeld, said in an interview on Wednesday. “A lot of people live and work and go to school right next to fields that are being sprayed with chlorpyrifos … It’s an issue of environmental health and justice.”

Epidemiological studies have linked chlorpyrifos to a number of health conditions. Pregnant women living near fields and farms that use the chemical have an increased risk of having a child with autism. Exposure to low to moderate levels of chlorpyrifos during pregnancy have also been associated with lower IQs and memory problems. California officials cited a recent review by a state panel on toxic air contaminants, which found the effects in children could occur at lower levels than previously understood.

Activists have accused the Trump administration of backing the interests of DowDuPont, a chlorpyrifos manufacturer whose predecessor donated to the president.

Climate change is expected to worsen pest challenges in agriculture, which means the need to find alternatives to toxic chemicals is urgent, said Blumenfeld: “It’s not just about chlorpyrifos. It’s making sure we have a more holistic and nature-based approach.”
