    铅(Pb)元素是重金属元素中含有神经毒性的一种,一旦人体体内铅元素含量超标就会对人的健康产生极大的影响[1]。儿童正处于生长发育的关键时期,若体内铅超标就会导致中毒,使钙、锌、铁等的代谢受到影响,从而造成的儿童缺锌、缺钙和血红蛋白的合成障碍等现象。轻者免疫力下降,重者则出现智商水平明显下降,另外还伴随着身体生长缓慢、多动症、视力、听力衰竭、性格变化无常、心律失常和间断性腹痛等中毒现象[2]。目前国际社会各界都对儿童的铅中毒给予了高度的重视,我国政府卫生机构也颁布了《儿童高铅血症和铅中毒预防指南》及《儿童高铅血症和铅中毒分级和处理原则》。本文主要分析洞头县学龄前儿童血铅水平, 现报道如下。
