Abstract: Objective To evaluate the children′s neurobehavioral functions after comprehensive management of Songhua River by mercury. Methods The polluted region by mercury of Songhua River after comprehensive management of Jilin City was used as survey group, and unpolluted region by mercury of Changchun City as control group. The mercury levels in water, soil, crops, and fish were detected in the two groups. Neurobehavioral Core Test Battery (NCTB) recommended by WHO was used to examine the neurobehavioral functions of 127 children in survey group and 156 children in control group. Results There were no significant differences of mercury content in river water, soil, and fish between survey and control groups, but the mercury content in crops of survey group was significantly higher than that of control group (P<0.05), and it was lower than that of national standards. There were no significant differences in six neurobehavioral functions between survey and control groups (P>0.05), only the wrong score of Pursuit Aiming Test Ⅱ in the survey group children was larger than that in the control group notably (P<0.01). Conclusion The comprehensive management of mercury pollution source has resulted in great improvement of environment quality, which has no significant effects on the children′s neurobehavioral functions.
