Lead poisoning
Lead poisoning is especially hazardous to children under six years of age. High levels of lead at this age can produce impaired neurological development that results in lifelong problems. A 1996 study showed 43% of children ages 1–5 had blood lead concentrations above the threshold considered dangerous by federal standards though more recent reports show this number to be lower. Another indication of hazard is the 24% miscarriage rate for women in the area, compared to a national average of 10%.
