为探讨污水灌溉所致环境铅污染及人群健康效应,应用WHO推荐的神经行为核心测试组合对某污水灌溉区52名儿童进行神经行为功能检查并测定血铅含量,同时测定污水灌溉区土壤、河水、农作物铅含量。结果表明,污水灌溉区土壤、河水、农作物铅含量明显高于对照区;污水灌溉区儿童血铅高于对照组,最慢反应时、数字译码、圣他·安娜手工敏捷度、视觉保留、目标追踪测试成绩较对照组明显降低。提示用含铅工业废水灌溉不仅使环境受到铅污染,而且使儿童铅负荷增高,中枢神经系统受到早期损害。
In order to explore the environmental lead pollution caused by sewage irrigation and the population health effects, 52 children in a sewage irrigation area were tested for neurobehavioral function and blood lead content by the combination of core behavioral tests recommended by the WHO. Soil and water of the irrigated area Crop lead content. The results showed that the content of lead in soil, water and crops in the sewage irrigation area was significantly higher than that in the control area. The blood lead level in the sewage irrigation area was higher than that in the control group, the slowest reaction time, digital decoding, Saint-Ana handwork agility, visual preservation, Target tracking test scores significantly lower than the control group. Prompted irrigation with lead-containing industrial waste water not only lead to environmental pollution, but also lead to increased child lead, the central nervous system suffered early damage.
