Abstract
In this study, mercury concentrations in freshwater fish from Lake An-dong basin were investigated and were compared with the results of the national freshwater fish monitoring survey. The mercury concentrations of fish from Lake An-dong were in the range of 37~611 ng/g and Korean piscivorous chub, the top predator showed the highest average mercury concentrations, 198±97 ng/g. Most of fish caught from upstream of Lake An-dong were herbivorous and omnivorous, and goby minnow and pale chub showed relatively lower mercury concentrations of 21±16 ng/g and 33±24 ng/g, respectively. Especially, mercury concentrations of long nosed barbel and largemouth bass caught from Lake An-dong were found to be higher than those of the average of the national survey monitoring data.
