Özet:

This paper presents data on the mineral and heavy metal contents of warty crab and brown shrimp caught along Sinop coast of the Middle Black Sea. Mineral and heavy metal analysis of the samples were done by TUBITAK Marmara Scientific Research Center (Gebze-TURKEY). Minerals were determined according to AOAC (1998); heavy metals were determined according to AOAC (1999); arsenic (Ar) was determined according to EPA (1992) and mercury (Hg) quantities were determined according to EPA (1994) methods. P, Zn, K and Na amounts in crab and P, Fe and Mg amounts in shrimp meats were higher than the daily recommendation. The amount of all mineral substances other than potassium in the shrimp and crab was significantly different from each other (P<0.05). P, Ca, Cu, Zn, Ni, Cr and Mn contents in the shrimp were less than crab while Fe, Ni, and Mg contents in crab were less than shrimp (P<0,05). The ratios of minerals in the crab and shrimp were P> K> Na> Ca> Mg> Zn> Cu> Fe> Mn> Cr> Ni and K> P> Na> Ca> Mg> Fe> Cu> Zn> Mn> Cr> N, respectively. The heavy metals (Ar, Hg, Cd, Pb, Co) detected in crab and shrimp. Except for Ar, heavy metal contents were higher in crab than in the shrimp.The heavy metal contents of the crab and shrimp were within food safety limits recommended by FAO/WHO, European Union and Turkish Food Codex. However, Pb contents of crab were over of the acceptability limit values.
