Abstract: Common compounds of lead include lead lead, yellow lead, honey soil ginseng, black tin lead, lead acetate, etc. There are many opportunities for exposure in daily life. Some traditional Chinese medicine prescriptions used to treat epilepsy, asthma, psoriasis and other chronic diseases also contain large amounts of lead. Some people mistakenly eat lead white as potato powder or alkaline noodles, causing lead poisoning. Since lead can be excreted through breast milk, breastfeeding women should be more careful. Young mother Xiaojuan has been very troubled recently. Her 5-month-old baby was diagnosed with lead poisoning! Xiaojuan didn\’t understand. How could the baby get lead poisoning if he was almost exclusively breastfed? It turns out that Xiaojuan had breast cancer a while ago.
