Regular consumption of fish has been widely recommended by health authorities. However, it is known that some species accumulate high levels of contaminants including heavy metals (e.g., Hg, Cd, Pb, and As). In this study, Cu, Pb, Co, Ni, Cr, Mn, Cd, and Fe were determined in the muscle tissue of 11 commercially available fish species (Sparus auratus, Dicentrarchus labrax, Mullus barbatus, Belone belone, Psetta maxima, Epinephelus aeneus, Salmothymus, Soleidae, Pomatomus saltatrix, Engraulis encrasicolus, and Sarda sarda) supplied from retailers in Kayseri, Turkey. Determinations were carried out by flame atomic absorption spectrometry after the wet digestion method. The average metal concentrations of the 11 species were determined in the range of 0.54-1.79, 0.82-1.40, 2.38-4.54, 1.23-3.67, 5.01-5.97, 0.77-3.59, 0.48-1.06, and 5.05-122.8 μg/g wet weight for Cu, Pb, Co, Ni, Cr, Mn, Cd, and Fe, respectively. The permissible tolerable daily intake (PTDI) and calculated daily intake (CDI) values were compared, and the calculated daily intake values of the samples were found to be below the established values. Correlations between the metal contents in samples were investigated by performing correlation tests with SPSS 13.0 for windows.
卫生当局广泛建议经常食用鱼类。然而，已知某些鱼类会积累高水平的污染物，包括重金属（如汞、镉、铅和砷）。在本研究中，测定了从土耳其开塞利零售商处供应的11种市售鱼类（金头鲷、舌齿鲈、条尾绯鲤、欧洲颌针鱼、大菱鲆、斑鳍鲈、地中海鳎、鳎科、美洲狼鱼、欧洲鳀和狐鲣）肌肉组织中的铜、铅、钴、镍、铬、锰、镉和铁。采用湿法消解后，通过火焰原子吸收光谱法进行测定。11种鱼类的平均金属浓度分别在0.54 - 1.79、0.82 - 1.40、2.38 - 4.54、1.23 - 3.67、5.01 - 5.97、0.77 - 3.59、0.48 - 1.06和5.05 - 122.8μg/g湿重范围内，分别对应铜、铅、钴、镍、铬、锰、镉和铁。比较了允许每日摄入量（PTDI）和计算得出的每日摄入量（CDI）值，发现样品的计算每日摄入量值低于既定值。使用Windows版SPSS 13.0进行相关性测试，研究了样品中金属含量之间的相关性。
