What is the method for reducing lead exposure in homes?

1. Regular cleaning and maintenance

2. Use of lead-based paints only

3. Ignoring peeling paint

4. Vacuuming without a HEPA filter

The correct answer is: Regular cleaning and maintenance

Regular cleaning and maintenance is a fundamental method for reducing lead exposure in homes because it helps to eliminate lead dust and prevent the accumulation of lead-contaminated materials. Dust that contains lead, which can be found in homes with lead-based paint or from contaminated soil, poses a significant risk, particularly to children who may ingest lead by putting their hands or objects that have come into contact with these surfaces into their mouths. By routinely cleaning surfaces, especially where children play and in areas prone to dust accumulation, households can significantly lower the potential for lead exposure. Maintenance also includes repairing any peeling or chipping paint, which can release lead particles into the environment. Conversely, using lead-based paints, ignoring peeling paint, and vacuuming without a HEPA filter can actually increase the risk of lead exposure. Lead-based paints are hazardous where lead is present, and neglecting deteriorating paint can exacerbate the problem by allowing lead to disperse further into the environment. Vacuuming without a HEPA filter may not effectively trap lead dust, allowing it to remain airborne or settle on other surfaces. Therefore, regular cleaning and maintenance serves as a proactive strategy to mitigate the risks associated with lead exposure in homes.
