Abstract

OBJECTIVES
This study was conducted to examine the effect of blood mercury on neurobehavioral performance in Korean elementary school students.
METHODS
We measured the blood mercury concentration in 1,077 elementary school students from Seoul, Busan, Daegu and Gwangju, then the students underwent computerized neurobehavioral test.
RESULTS
The mean concentration of blood mercury of study subjects was 2.10 microg/L. An increased blood mercury was associated with an increased reaction time in digit addition and symbol digit.
CONCLUSIONS
The blood mercury concentration of study subjects was very high compared to findings in a foreign country. We found several associations between blood mercury level and neurobehavioral performance.
