The neurological and behavioural effects of lead are believed to be irreversible. There is no known safe blood lead concentration. But it is known that, as lead exposure increases, the range and severity of symptoms and effects also increases.
Repeated low levels of exposure to lead can alter a child's normal mental and physical growth and result in learning or behavioral problems. If you are pregnant, exposure to high levels of lead can cause miscarriage, premature births, and smaller babies. Exposure can cause decreased mental ability, learning difficulties, and reduced growth in the children exposed to lead during pregnancy.
