Objectives: According to the 2007 Korea National Environmental Health Survey (KNEHS), some areas in theGyeongsang Provinces showed very high blood mercury levels in adults. We conducted this project to investigateany related health effects in children due to mercury levels in these areas. Methods: In total, 1,097 students between grades 3 and 6 at 19 elementary schools were recruited from fourareas with high mercury exposure as identified by the KNEHS. Total mercury levels in biological samples werecompared with health check-ups performed on the schoolchildren. Biological monitoring, supported byquestionnaires, a computerized neurobehavioral test, a posturography test and a personality test, were applied. Results: Triglycerides showed a significant relation with mercury in blood, urine and hair. Total mercuryconcentrations were divided into two groups: upper and lower concentration groups based on the median value. In the computerized neurobehavioral test, the upper blood mercury group showed a greater reaction time forcolor-word vigilance (p<0.05). In the posturography test, the intensity value of the tremor test showd highsignificant relations with mercury levels (p<0.01). In the personality test, self-consciousness, misdeeds and family relationships showed significant differencesbetween the upper and lower urine mercury groups (p<0.01), and specific reactions, ego resilience andhyperactivity also showed some differences (p<0.1). Conclusion: Some items in the neurobehavioral test, posturography test and personality test showed significantrelations with biological mercury levels. Therefore, monitoring and appropriate management of students showinghigh mercury levels are recommended in order to reduce their mercury exposure.
