The adverse health effects associated with childhood lead poisoning include reductions in mental and physical growth. Historically the main sources of lead in the home environment were:
lead based paint
lead contaminated soil from leaded gasoline
lead solder used in plumbing and lead pipes
Over time, the lead in these items has been lessened or removed, due to potential health hazards associated with lead. Today, however, the U.S. imports many products from foreign countries which don’t regulate lead; or if they do, their regulations are weak or not well enforced. Consequently we are seeing an increasing array of lead containing products in the United States.
