A new study from the University of California, Davis, found a possible link between pesticide exposure in pregnancy and autism in children.
Researchers found that children with an autism spectrum disorder were more likely to have mothers who lived close to fields treated with certain pesticides while they were pregnant. Exposure was also linked to other types of developmental delay in children.
Lead author Janie F. Shelton said, "Ours is the third study to specifically link autism spectrum disorders to pesticide exposure," however she told Reuters that more research is needed before scientists can say that pesticides cause autism. Explaining why pesticides could do this, she says that they all affect signaling between cells in the nervous system.
