Comparison of metal concentrations in tissues of blue crab, callinectes sapidus from mediterranean lagoons

Turkmen, Aysun/0000-0001-7461-4038; Turkmen, Mustafa/0000-0001-6700-5947; TEPE, Yalcin/0000-0002-8415-3754; TEPE, Banu/0000-0002-3428-8167WOS: 000293852900015PubMed: 21755288This study was performed to investigate the metal concentrations in muscle and gill of blue crab, Callinectes sapidus from Dortyol Lake, Akyatan Lagoon, Paradeniz Lagoon and CamlA +/- k Lagoon from the northeastern coastal area of Mediterranean Sea. So, the levels of cadmium, chromium, copper, iron, manganese, nickel, aluminum and zinc in tissues of specimens from the lagoons were determined by inductively coupled plasma optical emission spectrometer. The metal concentrations found in muscle tissue varied for Cd: 0.03-0.08, Cr: 0.05-0.13, Cu: 5.38-11.7, Fe: 21.1-38.2, Mn: 0.15-2.98, Ni: 0.24-0.45, Zn: 13.9-20.1 and Al: 1.2-13.7 mg/kg wet weight. Iron showed the highest levels in both tissues, and generally followed by zinc except gills. On the other hand, cadmium showed the lowest levels from all sites. Followed cadmium; chromium had the second lowest levels. The differences between mean metal concentrations from different sampling sites were statistically significant. Regional changes in metal concentration were observed in the tissues of the crabs, but these variations may not influence consumption advisories
