环境中低浓度铅对儿童神经行为功能的影响

Effect of environmental low concentration lead pollution on neurobehavioral function in children

对蓄电池厂周围环境的铅浓度和污染组77名儿童健康状况进行了检测，66名儿童作对照组。结果表明：污染区的大气、河水、大米、萝卜和土豆的铅浓度与对照地区相比，明显增高（P＜0．01）。污染组与对照组相比，6项神经行为功能中的4项有非常显著的下降（P＜0．01）。污染组儿童的血铅浓度明显高于对照组（P＜0．01）。提示：环境中低浓度铅污染可增加儿童血铅负荷，并可降低神经行为功能。

The lead concentration of the surrounding environment of the storage battery factoryand physical condition of 77 children of the contaminated group were measured,66 children as controlgroup. The results showed that the lead concentration of atmosphere, river water, rice, radish and potato in the contaminated area was higher, (P<0. 01). Four items out of 6 items in the neurobehavioralfunction for the children of the contaminated group were significantly lower (P<0. 001). The leadconcentration of blood in the children of the contaminated group was higher,too (P<0. 01). It suggesed that the environmental lead pollution of low concentration might enhance the blcod lead leveland might decline the neurobehavioral function.
