Which of the following materials is often associated with high levels of lead exposure?

Paint is often associated with high levels of lead exposure, particularly in homes built before the 1978 ban on lead-based paint in the United States. Many older homes and buildings used lead-based paint for its durability and aesthetic qualities. When this paint deteriorates or is disturbed during renovations or repairs, it can produce lead dust or chips that are hazardous if ingested or inhaled. This makes lead-based paint a significant health risk, especially for children, as lead exposure can cause serious developmental and health issues.

While each material listed has its own properties and applications, paint's historical use and the specific regulatory measures regarding its lead content make it particularly relevant in discussions of lead exposure risks. In contrast, wood, glass, and concrete do not typically carry the same associated risks for lead exposure.
