Overview of Childhood Lead Poisoning Prevention. Lead is a naturally occurring metal that can cause negative health effects. People are exposed to lead by eating lead paint chips, ingesting contaminated food or water, and/or by breathing in lead dust. Children younger than 6 years are more likely to be exposed due to their hand-to-mouth behavior.

Lead sulfide (PbS) is the world's primary source for lead, which is used in energy storage systems associated with power generation. The mineral contains an equal amount of Pb 2+ and S 2− ions, in a cubic structure. Zinc sulfide (ZnS) is a main source of zinc metal. It occurs as two polymorphs: a cubic sphalerite or a hexagonal wurtzite.
