Lead commonly occurs in which sources?

Lead exposure comes from materials and activities that historically contained lead. In drinking water, lead can enter from aging pipes, fixtures, and solder, with corrosion releasing lead into the water over time. In buildings, lead-based paints shed dust and chips that contaminate indoor environments and soil, posing ingestion or inhalation risks, especially for children. Industrial emissions from activities like smelting and refining release lead into air, which can settle as dust or contaminate soil and water supplies. These pathways make pipes, fixtures and solder, paints, and industrial emissions the most common sources of lead exposure. Fresh rainwater, microplastics, and fresh fruit are not typical sources of lead exposure.
