对某蓄电池厂周围环境的铅浓度和污染组儿童的健康状况进行了检测。６６名儿童为对照组。结果表明污染区的大气、河水、大米、萝卜和马铃薯的铅浓度与对照地区相比明显增高（Ｐ＜０．０１）。污染组儿童与对照组相比，６项中的４项神经行为功能明显下降（Ｐ＜０．００１）。污染组儿童的血铅浓度、淋巴细胞染色体畸变率和微核率分别为４３１．０±１３．０μｇ／Ｌ、１．８７±１．０１％和７．１４±１．９‰，明显高于对照组（Ｐ＜０．０１）。这表明，环境中低浓度铅污染可增加血铅负荷和遗传物质损伤，并且可降低神经行为功能。
The lead concentration in the environment around a battery factory and the health status of children in the contaminated group were tested. 66 children as control group. The results showed that the concentrations of lead in the air, water, rice, radish and potato in the contaminated area were significantly higher than those in the control area (P <0.01). Compared with the control group, four of the six children in the contaminated group had significantly lower neurobehavioral functions (P <0.001). The levels of blood lead, lymphocyte chromosome aberration and micronucleus in the contaminated group were 431.0 ± 13.0 μg / L, 1.87 ± 1.01% and 7.14 ± 1.9 ‰, respectively, which were significantly higher than those in the control group Control group (P <0.01). This suggests that low concentrations of lead contamination in the environment may increase blood lead load and genetic material damage and may reduce neurobehavioral function.
