Health Effects of Lead
Lead is a potent neurotoxin with no safe level of exposure. In children, lead causes developmental delays, reduced IQ, and behavioral problems. In adults, it causes high blood pressure, kidney damage, and cardiovascular effects. Pregnant women face increased risk of premature birth.
