Extremely tiny PCB concentrations cause permanent fetal brain and IQ damage

Evidence

In 2000, researchers calculated that a PCB concentration of just 5 parts per billion in a pregnant mother’s blood can have adverse effects on a developing fetal brain, giving rise to attention and IQ deficits that appear permanent.60 Five parts per billion is equivalent to one drop in 118 bathtubs full of water. — Harriet A.
