工业化与城市化的进程加快,环境铅浓度不断增加,环境铅污染日趋严重。处于生长发育期的儿童,尤其是0-6岁儿童,因其生理和发育上的特点,对铅毒性作用更为易感和脆弱,即使低剂量铅暴露也可引起儿童全身性、多系统的损害。1铅的来源1.1大气铅污染含铅汽油燃烧后排出的废气及铅作业工厂排放的废气是大气铅污染的主要来源。1.2室内含铅涂料及油漆使用含铅油漆或涂料是造成室内环境铅污染的主要原因,使得生活在里面的儿童血铅负荷增加。1.3食物及饮水空气中的铅尘及铅作业工厂排放的含铅
The process of industrialization and urbanization is accelerating, the concentration of environmental lead is increasing, and the environmental lead pollution is worsening day by day. Children in their growth and development, especially those aged 0-6, are more susceptible and vulnerable to lead toxicity because of their physiologic and developmental characteristics, even though exposure to low doses of lead can also cause systemic, multisystemic damage. 1 Sources of Lead 1.1 Air Pollution Lead Dioxide and Lead Exhausted after Leaded Gas Burning Exhaust gas from factories is the main source of lead pollution in the atmosphere. 1.2 Indoor Lead Paint and Paint The use of lead paint or paint is the main cause of lead contamination in the indoor environment, resulting in increased blood lead load in children living therein. 1.3 Food and drinking water lead dust and lead in the air factory discharge of lead
