A study led by Columbia University links prenatal exposure to chlorpyrifos (CPF) with lasting brain changes and reduced motor skills in children in New York City.
The 270-participant study found higher CPF exposure correlated with brain differences and poorer motor performance.
Despite the U.S. Environmental Protection Agency (EPA) banning chlorpyrifos for household use in 2001, it remains in agricultural use, posing ongoing risks to farm workers and pregnant women.
