环境铅污染问题日趋受重视，儿童铅损害已成为城市儿童最重要的公共保健问题。国内外研究表明〔１，２〕；由于发育中的神经组织对铅蓄积所致毒性较敏感，环境中低浓度的铅污染可影响儿童的神经行为发育，表现如易冲动、注意力下降、学习困难、智力低下等。铅的神经毒机理极复? The problem of lead pollution in the environment has gained increasing attention. Children’s lead damage has become the most important public health problem for urban children. Domestic and foreign studies have shown that [1,2]; due to the development of nerve tissue is more sensitive to toxicity caused by lead accumulation, the environment of low concentrations of lead pollution can affect children’s neurobehavioral development, such as impulsive performance, decreased attention, learning Difficulties, mental retardation and so on. Lead nerve poison extremely complex mechanism?
