Abstract

The purpose of this study was to determine and to compare the amount of heavy metals in the meat of white (N = 39) and blue (N = 35) sea fish, considering the spring (N = 38) and fall (N = 36) catch period to study the possible type and seasonal differences especially in Hg concentrations in fish, and to estimate if the amounts registered can have a harmful effect on consumer health. The fish were chosen as an indicator of eco-system contamination with mercury and other heavy metals. The amount of heavy metals, lead (Pb) and cadmium (Cd), in both groups was lower than the Highest Permissible Amounts regulated by law in Croatia and the European Union. Mercury (Hg) exceeded the maximum allowed value in just a number of samples 3/74 (0.04%), while it is relevant for arsenic (As) to be present in almost any sample, although it has simultaneously not been regulated by law. The statistically significant value of arsenic exists in blue fish during the spring period, and the amount of mercury is higher in white fish compared to blue fish. Also a statistically significant difference in mercury levels was recorded during fall compared to spring,. Given the dietary habits and frequent fish consumption in Croatia, there is no risk of harmful health effects.
