Lead Lead poisoning has been linked to lower IQ scores in children exposed to even low levels of lead. Lead can increase blood pressure and cause fertility problems, nerve disorders, muscle and joint pain, irritability, and memory or concentration problems. It takes a significantly greater level of exposure to lead for adults than it does for kids to sustain adverse health effects. Most adults who are lead poisoned get exposed to lead at work. Occupations related to welding, renovation and remodeling activities, smelters, firing ranges, the manufacture and disposal ofcar batteries, and the maintenance and repair of bridges and water towers, are particularly at risk for lead exposure. Long-standing National surveys,such as the National Health and Nutrition Examination Survey, show that lead levels have decreased in all children, black children and poor children continue to have higher levels of lead detectable in their blood.
