Abstract

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.

Keywords: Caspian Sea; Liza aurata; Mercury; Rutilus frisii kutum; Sander lucioperca.
