简单地说,铅中毒就是血液中含过量的铅。世界卫生组织对血铅含量的安全标准是10微克每分升,高于这个标准就属于铅中毒。铅中毒对儿童的智能发展、身体发育均会产生不利影响。儿童摄入的铅主要来自环境。铅多集聚在贴近地面1米左右的大气中,离地面越近,铅的浓度越高,而距地面1米处正好是儿童的呼吸带。因此,儿童从空气中所吸入的铅比成人高数倍。此外,儿童特有的手——口行为也造成儿童较其他人群有更多接触铅的机会。防治儿童铅中毒的重点在于预防。△培养良好的卫生习惯,教育婴幼儿不吸吮手指,不将异物放入口中,进食前必须洗手。家长要经常清洗儿童的玩具和其他一些有可能被孩子放到口中的物品。食品及婴儿的餐具要随时盖好,以免尘土落入。指甲缝是特别容
In short, lead poisoning is the excess lead in the blood. WHO safety standards for blood lead is 10 micrograms per liter, higher than this standard belongs to lead poisoning. Lead poisoning can have adverse effects on children’s intellectual development and physical development. Lead intake of children mainly from the environment. Lead is concentrated in the atmosphere about 1 meter close to the ground, the closer to the ground, the higher the concentration of lead, and just 1 meter away from the ground is the breathing zone of children. As a result, children breathe in air several times more often than adults. In addition, child-specific hand-mouth practices also give children more access to lead than other groups. Prevention of lead poisoning in children focused on prevention. Train good health habits, educate infants and young children do not suck your fingers, do not put foreign matter into the mouth, must wash their hands before eating.
