Asbestos, a highly regulated naturally occurring mineral, has been extensively utilized in common building & insulation materials in schools & other buildings beginning in the early 1900's.

Residential & occupational exposure to lead-based paint is one of the leading causes of high lead in blood levels in affected individuals.  In children, excessive blood-lead levels can seriously damage a child's brain & central nervous system.  In adults, high blood-levels can cause neurological disorders and infertility.
