What are two common sources of hazardous lead in homes?

Hazardous lead in homes primarily comes from older sources that were commonly used in construction and renovation. Older paint often contained lead as a pigment for color and durability, making it a significant source of lead exposure, especially in homes built before 1978 when the use of lead-based paints was banned in residential properties in the United States. As paint deteriorates and creates dust or chips, it can pose health risks, particularly to young children who may ingest or inhale lead particles.

Additionally, lead pipes were frequently used in plumbing systems before the 1980s, and homes that have these old pipes can leach lead into drinking water, creating another significant health hazard. This combination of older paint and lead pipes accounts for the two prevalent sources of hazardous lead in many homes. Recognizing these risks is crucial for homeowners and professionals involved in renovation or maintenance work to ensure safety and compliance with health regulations.
