✔️Increasing dietary calcium reduces lead absorption in the body because calcium and lead compete for the same binding sites in bones and tissues.

✔️Adequate calcium intake helps block the uptake of environmental lead, lowering the risk of toxicity.

✔️This approach is especially important for children and pregnant individuals, who absorb a higher percentage of ingested lead.

✔️Calcium-rich foods help strengthen bones, reducing the storage and retention of lead in bone tissue.

✔️ This is an evidence-backed prevention strategy used in public health guidelines for lead exposure prevention.

Ensure proper ventilation when using cleaning products.

✔️While ventilation is important for chemical exposure prevention, it does not reduce lead exposure, which is primarily from old paint, contaminated soil, or lead pipes.

✔️Cleaning products do not typically contain lead, so this intervention does not address the actual hazard.

✔️This option confuses general environmental safety with specific lead prevention.

✔️It provides no protection against ingestion or inhalation of lead dust.

✔️Therefore, it is not relevant to preventing lead exposure.

Let cold water run every morning to flush pipes out.

✔️Running cold water helps when pipes contain lead, but this step alone does not sufficiently reduce exposure.

✔️The most effective method is avoiding hot tap water for cooking and using certified filters—not just flushing lines.

✔️Flushing water may reduce lead concentration but is not reliable as a primary prevention strategy.

✔️Lead particles can still leach from older plumbing systems even after flushing.

✔️Thus, this is not the best or most effective preventive action.

Avoid using plastic containers when reheating food.

✔️Plastic reheating safety relates to BPA or chemical leaching, not lead exposure.

✔️Lead is not typically found in food-grade plastics, so this practice does not reduce lead risk.

✔️This option addresses a different health concern, unrelated to environmental lead.

✔️It provides no benefit in reducing lead ingestion, inhalation, or absorption.

✔️Therefore, it is incorrect for lead exposure prevention.
