Mercury, lead, cadmium and chrome concentration levels were determined in liver tissue of two different fish species of Adriatic Sea, Red mullet (Mullus barbatus) and European hake (Merluccius merluccius). The concentration levels of heavy metals were measured by using atomic absorption spectrophotometer (AAS). Heavy metals concentration in both liver tissue of fish species ranged as follows, Hg: 0.02-0.15, Pb: nd-0.04, Cd: 0.11-0.22, Cr: 0.10-0.13 (mg/kg wet weight). As expected, liver tissue of red mullet showed different variation of mercury (p<0.001), as well as variation between same fish species with different weight. The result of the study confirmed the fact that liver tissue of Red mullet and European hake are an important location and indicator of heavy metal pollution. Based on the economic and culinary importance of both fish species among consumers it will be of specific interest the further monitoring with the goal to safeguard the consumers health.
