Chlorpyrifos is an endocrine disrupter used in pesticides. There is strong evidence to suggest that even at very low doses, the chemical triggers effects among children ranging from lower IQ to higher rates of autism. The National Institutes of Health concluded that chlorpyrifos can cause “adverse developmental, reproductive, neurological, and immune effects.” Many public health experts, scientists, and environmentalists have for years been pushing for a ban on chlorpyrifos.
The EPA under Obama began the process of banning this chemical. Trump's EPA stopped this process. Last week a number of farm workers in Bakersfield, CA, were exposed to the chemical and became quite ill.
