What is a common source of lead exposure in residential settings?

Indoor air pollution
Household dust
Water pipes
Imported toys

The correct answer is: Household dust

Household dust is a common source of lead exposure in residential settings because it can accumulate lead particles from various sources, such as deteriorating lead-based paint, soil tracked in from outside, and other lead-containing materials. When paint containing lead chips or dust falls off surfaces, such as windows and doors, it can settle in dust, particularly in homes built before 1978 when the U.S. banned the use of lead-based paint in residential properties. Children, who are more likely to engage in hand-to-mouth behaviors, can ingest this dust, leading to potential lead poisoning. Regular cleaning and maintaining a dust-free environment are critical in minimizing lead exposure in homes with a history of lead-based paint use. This highlights the importance of addressing household dust as a significant vector for lead exposure, especially in older homes.
