Lead levels can be measured in the blood to tell how much exposure to lead a person has had. Even low levels of lead in blood have been shown to affect children’s abilities to learn, pay attention, and do well in school. There is no safe level of lead. Children can be exposed to lead from different sources such as paint, gasoline, and other products such as some types of folk medicine. Children may also be exposed to air, food, water, dust, and soil that has lead in it. The most common source of dangerous lead levels in children is from lead-based paint in houses. In homes built before 1940, 87% of those homes have lead in the paint.
