Cigarette smoke is the most common source of exposure to cadmium, a toxic metal found in the earth’s crust, used in batteries, pigments, metal coatings and plastics. Lead, a toxic metal also found in the earth’s crust, is used in a variety of products, such as ceramics, pipes, and batteries. Common sources of lead exposure in the United States include lead-based paint in older homes, lead-glazed pottery, contaminated soil, and contaminated drinking water (PMID: 20933593).
