Establishing on Heavy Metal Accumulation in Some Economically Important Fish Species Captured from Kastamonu Costal

33648

This study aimed at examining heavy metal accumulation in haddock (Merlangius euxmus), bony fish (Sarda sarda), mackerel (Trachurus trachurus) and red mullet (Mullus barbatus) captured between İnebolu and Cide harbor region. Fish samples were collected during 2014 to 2015 covering a whole year. From each different fish samples, including at least 25-30 for each species were collected using appropriate crafts and gears, and transferred to the laboratory on the same day in cold chain. Two gill spines, whole liver and 5 g muscle tissues taken from each fish species. Heavy metal analysis results showed that iron content in the tissue of all species was higher compared to other metals. The lowest average was 23.23 mg kg^-1 in bony fish muscle and the highest level was 48.89 mg kg^ -1 in red mullet muscle. The lowest and the highest average values ranged between 189.65-267.45 mg kg-1. Cadmium content was measured as the lowest in mackerel muscle (0.16 mg kg-1) and the highest in bony fish muscle (0.28 mg kg-^1). Gills and liver contained higher cadmium accumulation compared to muscle tissue. Although, lead content was between 5.48 mg kg^-1 and 7.21 mg kg^-1 in muscle tissue, its higher level in gills and liver was between 8.87-12.26 mg kg^ -1. While the lowest nickel content was 2.21 mg kg^-1 in the muscle, cupper value in the muscle ranged between 2.35-4.52 mg kg^-1. In this context, iron, copper, nickel and zinc levels were found to be within acceptable limits in regard to Turkish Food Codex, European Union Directives and World Health Organization, although cadmium and lead contents were higher.
