Which is a common method for reducing lead exposure in homes?

Frequent cleaning and maintenance are essential practices for reducing lead exposure in homes, particularly in settings where lead-based paints or lead dust may be present. Dust is a major pathway for lead exposure, especially in homes built before the 1978 ban on lead-based paint. Regular cleaning helps to remove lead dust from surfaces such as floors, windowsills, and other areas where lead particles can accumulate.

Using wet cleaning methods, such as damp mopping or using wet cloths, can effectively capture and remove lead dust rather than simply dispersing it into the air. Maintenance practices that address peeling or deteriorating paint can also prevent the release of lead dust and chips, thereby reducing potential exposure risks.

While the other choices do have individual merits in promoting overall health and safety, they do not specifically target lead exposure in a direct manner. For example, encouraging outdoor play may reduce indoor exposure but does not eliminate lead hazards inside the home. Similarly, installing carpets can help to some extent by trapping dust but may not be as effective as regular cleaning in eliminating lead dust. Natural cleaning products may be environmentally friendly, but their effectiveness specifically in removing lead dust is variable and not a recognized best practice for lead reduction.
