Harmful Effects of Lead

Lead is more harmful than you think. Children with elevated body lead burdens had a four to five-point deficit in mean verbal IQ scores compared with children from same communities with lower lead burdens. Early exposure may cause intelligence and learning disabilities, poor concentration and behavioral problems. The human brain has little capacity for repair, these effects are untreatable and irreversible. They cause diminution in brain function and reduction in achievement that last throughout life.
