Health News # 512-PCB Exposure Linked to Low IQ September 18 , 1996

A study published September 12, 1996, in the NEW ENGLAND JOURNAL OF MEDICINE confirms that children exposed to low levels of PCBs in the womb grow up with low IQs, poor reading comprehension, difficulty paying attention, and memory problems.[1] PCBs are a family of toxic industrial chemicals commercialized in 1929 by Monsanto, and now found in nearly all humans on earth. (See REHW #327.) This latest study describes a group of 11-year-old children whose mothers ate 2 to 3 meals per month of fish from Lake Michigan for at least 6 years before giving birth. The children's mental and physical growth have been followed since birth. The greatest mental deficits have occurred in the 11% of the children whose mothers ate the most fish.[2]
