对某金矿工人199人（对照组108人）进行的神经行为功能研究表明：接触组情绪状况得分（除有力-好动一项）和其余各项行为学指标得分均低于对照组。且随接触汞浓度增加，大多数行为功能得分呈递减趋势．在较低汞浓度接触组（平均为0．0114mg／m3）神经行为功能得分明显低于对照组。尿汞含量＜49．85nmol／L的汞作业工人神经行为异常人数明显高于对照组。提示：长期职业接触汞蒸气在未引起明显的临床损害之前神经功能已经受到不良影响，表现为注意力、手眼配合协调能力、记忆力、学习能力下降及情绪状况异常。
The neurobehavioral study on 199 gold miners (control group 108) showed that the score of emotional state (except vigorous-active) and the rest of the behavioral indexes in the contact group were lower than those in the control group. And with the increase of exposure to mercury concentration, most of the behavioral functional scores showed a decreasing trend. Neurobehavioral scores of the exposed group (mean, 0.0114mg / m3) were significantly lower than those of the control group in the lower mercury concentration group. Mercury mercury content <49.85nmol / L of mercury workers exposed to neurobehavioral disorders was significantly higher than the control group. Hint: Long-term occupational exposure to mercury vapor has been adversely affected in neurological function without causing significant clinical damage, with attention, hand-eye coordination, memory loss, decreased learning ability, and abnormal mood conditions.
