When pregnant women are exposed to moderate
levels of a common pesticide, their children may experience lasting
changes in brain structure linked to lower intelligence, a US study said
Monday.
The study in the Proceedings of the National
Academy of Sciences examined New York City pregnant mothers who were
tested for exposure to chlorpyrifos, or CPF, which is widely used for
pest control in farms and public spaces.
The women in the study, which included 369
subjects total, took part prior to 2001 when CPF was banned from
household use in the United States, though the chemical continues to be
used worldwide in agriculture.
