When lead is released into the air from industrial sources or vehicles it can travel a long distance before reaching the ground. In some instances, it can move from the soil into groundwater.
Federal and state regulatory standards have helped to reduce the amount of lead in air, drinking water, soil, consumer products, food, and occupational settings.
Lead exposure can cause damage to many parts of the body. There is no known safe level of exposure to lead. Compared to adults, children are more likely to be harmed by lead. Even low levels can damage children's nervous systems resulting in:
- Lower IQs.
- Learning disabilities.
- Behavior problems.
In adults, the cardiovascular system is most sensitive to low-level lead exposure. Learn more about the dangers of lead poisoning.
