对接铅工人的血铅、锌卟啉水平，行为功能和尿液中单胺类神经递质及其代谢产物的含量进行了研究。结果显示：血铅、锌卟啉的平均含量分别为３．４０μｍｏｌ／Ｌ和４．７μｍｏｌ／Ｌ，比对照组明显增高；尿液中高香草酸（ＨＶＡ）和肾上腺素（Ｅ）的含量显著高于对照组；工人的行为功能受到一定影响，表现为简单反应时、利手提转捷度、数字译码、视觉保留时间、目标追踪和情感状态的改变。结果提示：运用神经行为核心测试组合以及检测尿中肾上腺素、多巴胺及其代谢产物高香草酸和３，４－双羟苯乙酸的变化，有助于及早发现铅对神经系统的损害，以及探索铅致行为功能改变的生物学基础。
The lead, zinc porphyrin levels, behavioral function, and monoamine neurotransmitters and their metabolites in docked lead workers were investigated. The results showed that the average levels of blood lead and zinc porphyrin were 3.40μmol / L and 4.7μmol / L, respectively, which were significantly higher than those of the control group. The contents of HVA and E in urine were significantly higher In the control group, the worker’s behavioral function was affected to some extent, which was reflected in the following aspects: simple response, hand movement, digital decoding, visual retention time, target tracking and emotional status changes. The results suggest that the combination of neurobehavioral core testing and the detection of urinary epinephrine, dopamine and their metabolites homovanillic acid and 3,4-dihydroxyphenylacetic acid may contribute to the early detection of lead damage to the nervous system and to exploration The Biological Basis of Lead-induced Behavior Changes.
