Question
The child has a blood lead level of 126, is hyperactive with poor memory, and often experiences knee pain. They have previously taken calcium and zinc supplements, but the effects were not significant. Is taking a lead-chelating oral solution effective? If not, what should be done?
Answer
For the vast majority of children with blood lead levels below 250 micrograms per liter, correcting poor lifestyle and hygiene habits can help restore normal blood lead levels within a short period without the need for medication or lead-chelating foods. It is recommended to strengthen hand hygiene education, avoid prolonged stays in heavily polluted areas, and help children develop good hygiene habits. Additionally, dietary measures should include drinking more milk, eating fewer lead-containing foods, and supplementing with adequate calcium, iron, and zinc. Consuming high-fiber and iodine-rich foods can also help prevent the body from absorbing lead.
