摘　　要：Twice a year continuous samples of Rana Chensinensis and sediments have been collected near gold mine in the upstream region of Songhua River from 2000 to 2002, for analyzing the total mercury (THg), methylmercury (MeHg) concentration and correlation in sediments, muscles, livers of the frog. The study indicates that THg and MeHgconcentrations in polluted samples near the gold mine are higher than those in unpolluted ones. THg and MeHg con-centrations are higher in autumn, in female, and in livers than those in spring, in male, in muscles respectively. The order of concentration degree in the frog organizations is as follows: liver>muscle>ovum>Fallopian tube. MeHg is themain form of mercury (Hg) existing in autumn, while inor-ganic Hg is in spring. There is no distinct difference ofCMeHg/CTHg between male and female, livers and muscles. The correlation between MeHg concentrations in the river sedi-ments and in the frog’s livers and muscles are significant, which is related to disorderly discharge of Hg.Twice a year continuous samples of Rana Chensinensis and sediments have been collected near gold mine in the upstream region of Songhua River from 2000 to 2002, for analyzing the total mercury （THg）, methylmercury （MeHg） concentration and correlation in sediments, muscles, livers of the frog.
