Lead is a heavy metal with strong accumulation, which is very toxic to human body and can cause damage to multiple organs, and lead pollution in the environment is the main cause of lead poisoning in children. Children’s bodies are growing and developing, and their absorption and toxic reactions to lead are higher than those of adults, so it is necessary to raise public awareness of lead poisoning in children. It is necessary to correct misconceptions and eliminate unnecessary panic. Scenario 1: Is lead poisoning when lead in trace elements exceeds the standard? Ms. Wang is a 1-week-old baby’s mother, who usually pays much attention to life hygiene and brings up her little one with great care. In the experience, she found that the lead in trace elements exceeded the reference value, could it be lead poisoning? The doctor only said to review the test, do we need to take medicine to treat it? Scenario 2: Can chewing pencils cause lead poisoning? Mr. Li’s baby is in elementary school and has been doing well in school, which Mr. Li is proud of. However, Mr. Li has not been happy recently because his baby has a bad habit of chewing on pencils, which Mr. Li is worried will cause lead poisoning. About metal lead, the public lacks proper scientific understanding. There are even unscrupulous businessmen who are making a big fuss about lead poisoning for the sake of profit, which leads to the abuse of lead repellent drugs, or advocate the lead repellent effect of certain food or health products for profit-making purpose. Let’s talk about the problems in the above scenario one. The test results of trace elements are affected by many factors, and the lead in them does not represent the real level in the body, which means that trace elements cannot be used as a criterion to diagnose lead poisoning, and the blood lead level in the veins should be checked. Therefore, when lead in trace elements is found to be over the limit, it is important to recheck it after 1 month or check the venous blood lead level. What parents should do is to check if their babies have been exposed to lead, such as toys with heavy oil colors containing lead. Rather than rushing to find medications to take. The key to the problem in Scenario 2 is whether the pencil contains lead. Parents do not need to be nervous about this, as pencils are made of graphite and clay, which have nothing to do with lead, so there is no need to worry about lead poisoning at all. However, the bad habit of chewing pencils should be corrected because it is unhygienic and also affects the development of teeth. China’s children lead poisoning problem is serious China’s children lead poisoning is mostly directly related to lead pollution in the environment, often in groups, and the cases are alarming: In September 2006, 373 children were diagnosed with severe lead poisoning in Shuiyang Township, Hui County, Gansu Province. The State Environmental Protection Administration sent experts to investigate that a lead ingot smelter in Shuiyang Township was the “culprit”; in July 2007, lead pollution in Xiangyou lead smelter in Putian, Fujian Province, caused 200 children to exceed the lead standard; in June 2009, Tianli Storage Battery Company in Lincheng Township, Changxing County, Zhejiang Province, caused environmental lead pollution, resulting in more than 500 people with blood lead exceeded the standard and accounted for 62.5% of the population tested; in August 2009, Fengxiang County, Shaanxi Province, Changqing Town, Dongling Smelting Company caused environmental lead pollution, 615 children’s blood lead exceeded the standard, accounting for 84% of the population examined; in October 2009, Jiyuan City, Henan Province, a major child lead poisoning incident in 3108 children’s blood lead above 250ug/L… … What are the manifestations of lead poisoning? The manifestations of lead poisoning in children are non-specific and can include abdominal pain, anemia, constipation, hyperactivity, and impulsivity. In severe cases, there can be coma, convulsions and other manifestations of encephalopathy. The diagnosis relies on the blood lead level in the veins, and the defined criteria are: two consecutive blood leads in the range of 100~199ug/L for hyperleademia; two consecutive blood leads above 200ug/L for lead poisoning. The treatment is based on getting out of the lead contaminated environment, and the blood lead level can drop significantly one month after no more exposure. When the blood lead level is above 250ug/L, it is necessary to consider the use of drug lead repellent treatment. The first choice is dithiobutyric acid, and lead repellent treatment must be carried out in regular medical units, not to listen to rumors and eat various health products. Staying away from lead pollution is the key to treatment When lead is found to be over the limit, parents should pay attention to find the cause. Industrial pollution includes lead mining, smelting, battery production and recycling enterprises, shipbuilding industry, cable manufacturing, etc.; pollution in life includes children’s painting paints, mothers’ cosmetics, tin foil for making egg tarts, tin pots for water, second-hand smoke environment, car exhaust, etc. Don’t take your child to play near lead work factories. Don’t give your baby toys with heavy oil paint during the baby’s micturition period, which may lead to lead poisoning due to the baby chewing on them. Pregnant women and children should stay away from second-hand smoke. Don’t play near the highway, car exhaust contains lead, which can enter your baby’s body through breathing. Families with old iron pipes should not use water that stays in the pipes for a long time for babies to drink or cook with. Lead poisoning in children should be a concern for the whole society, and we should find ways to reduce industrial pollution in order not to cause the above-mentioned mass incidents. Return a healthy environment to our children.
