We aimed to investigate mercury level in three species of fish such as Sander lucioperca, Liza aurata, and Rutilus frisii kutum. Sampling was done in the southern coasts of the Caspian Sea. The ranges of mercury level in S. lucioperca, L. aurata, and R. frisii kutum were 104.67-675.33 ppb, 60.66-175.33 ppb, and 123.33-170.33 ppb, respectively. Results revealed that the mercury level in S. lucioperca was more than the allowable limit at several sites, while it was less than the allowable limit in R. frisii kutum and L. aurata at all sampling sites. Further, the target hazard quotient (THQ) index for S. lucioperca was >1 at some sites and <1 for other species at all sites. The maximum allowable consumption for each species at the study area was measured daily and monthly.
本研究旨在调查三种鱼类（北方欧鳗、欧洲鳗鲡和白斑狗鱼）中的汞含量。采样地点位于里海的南部沿海。北方欧鳗、欧洲鳗鲡和白斑狗鱼的汞含量范围分别为 104.67-675.33 ppb、60.66-175.33 ppb 和 123.33-170.33 ppb。结果表明，在几个采样点北方欧鳗的汞含量超过了允许的限度，而在所有采样点白斑狗鱼和欧洲鳗鲡的汞含量都低于允许的限度。此外，北方欧鳗的目标危害系数（THQ）指数在一些采样点>1，而其他两种鱼类在所有采样点均<1。研究区域内每种鱼类的最大允许日摄食量和月摄食量也进行了测算。
