Pesticide Exposure in Womb Linked to Lower IQ

Children exposed to pesticides in the womb are more likely to have measurable problems with intelligence, memory, and attention, three new studies show.

The pesticides in question, a class of chemicals called organophosphates, have long concerned both scientists and regulators because they work by irreversibly blocking an enzyme that’s critical to nerve function in both bugs and people.

Even at relatively low levels, organophosphates may be most hazardous to fetuses and young children, where healthy brain development depends on a carefully orchestrated sequence of biological events.
