Sažetak
Mercury (Hg) concentrations were determined in nine marine fish species and two freshwater fish species obtained from the market. Concentrations ranged from 6.3 to 276.6 μg/kg. The lowest mean value of 15.2 μg/ kg was determined for trout and the highest of 141.3 μg/kg for tuna. Similar mean Hg concentrations (31.8, 32.2 and 48.0 μg/kg) were measured for the marine fishes: hake, Atlantic mackerel and mackerel. Similar mean Hg values (74.4 and 80.9 μg/kg) were determined for gilthead sea bream and salmon-bass. Hg concentrations were statistically significant higher in tuna and European sea bass compared to hake, sardine, Atlantic mackerel, mackerel, cod, trout and carp (p<0.05 to p<0.0001). Hg levels in gilthead sea bream were significant lower than in tuna (p<0.01), but significantly higher than in trout (p<0.01). Sardines and common dentex showed significantly higher Hg content in comparison to Atlantic mackerel and cod (p<0.01 to p<0.001). Salmon-bass had a significantly higher Hg content than Atlantic mackerel, cod, mackerel, and trout and carp (p<0.01 to p<0.0001). In this study, no Hg concentration exceeded the maximum permissible limits of 1000 μg/kg for tuna or 500 μg/kg for other fish species. Comparing the obtained concentrations with the literature
data, it can be concluded that the measured Hg levels in the analysed fish species are lower than those from the Mediterranean Sea. The health risk deriving from the measured Hg levels was estimated using the available toxicological limit of tolerable weekly intake (TWI) of 1.3 μg/kg/b.w/week. The contribution of the Hg levels to the TWI value using the average daily consumption of fish in Croatia is low, and the highest percentage was determined for tuna (7.54%) and European sea bass (6.08%). For other fish species, the contribution to the TWI ranged from 0.85 to 4.23%. The contribution to the TWI value based on a fish meal of 150 g/day exceeded 100%, i.e. 163.1% and 134.6% for tuna and European sea bass, giving 2.12 and 1.75 μg/ kg/day (the safety margin is 0.19 μg/kg/day). Therefore, the frequently consumption of tuna and European sea bass per week over longer periods may have toxicological consequences on consumers. Therefore, the intake of Hg via the consumption of tuna and European sea bass is significant, especially compared to other fish species, and therefore regularly monitoring and evaluation of the Hg content in these two species is necessary.
