Scorpionfish (Scorpaena porcus) is a demersal fish species commercially important for its of which meat is tough and delicious. The aim of this study was to determine heavy metal (Al, Cu, Ni, As, Cd, Hg, Pb, U) concentrations in this fish species which is traditionally consumed in the Black Sea Area and, to compare the concentrations of various toxic elements in different organs of the fish specimens (muscle, liver, gill, and skin). Within this scope, the mineralization was performed using microwave digestion system. Thirty-two scorpionfish caught from Sinop Inland Port during 2010 were analyzed. The heavy metal concentrations were determined with the method of inductively coupled plasma mass spectroscopy (ICP-MS). Verification of the method was demonstrated by analysis of standard reference material (NRCC-TORT-2 lobster hepatopancreas). After evaluation of the results, it was determined that the highest heavy metal accumulation was generally found in the liver. The maximum aluminum level and the minimum uranium level were found in the analyzed tissues. In terms of heavy metals, Al, Cu, Cd, and Hg showed a statistically significant difference between tissues (p < 0.05). It was determined that heavy metal concentrations obtained from the muscle tissues did not exceed the national and international recommended limits; and also it was found that daily intake amounts did not exceed tolerable daily intake amounts. Furthermore, in THQ based risk evaluation, the value 1 which is crucial for children and adults was not surpassed. In terms of public health, it was found out that there was not any risk in consumption of scorpionfish in the study area.
鲉鱼（Scorpaena porcus）是一种底栖鱼类，因其肉质坚韧且美味而具有重要商业价值。本研究的目的是测定在黑海地区传统食用的这种鱼类中的重金属（铝、铜、镍、砷、镉、汞、铅、铀）浓度，并比较鱼样本不同器官（肌肉、肝脏、鳃和皮肤）中各种有毒元素的浓度。在此范围内，使用微波消解系统进行矿化处理。对2010年从锡诺普内陆港捕获的32条鲉鱼进行了分析。采用电感耦合等离子体质谱法（ICP-MS）测定重金属浓度。通过分析标准参考物质（NRCC-TORT-2龙虾肝胰腺）对该方法进行了验证。对结果进行评估后，确定重金属积累量最高的通常是肝脏。在所分析的组织中发现了最高的铝含量和最低的铀含量。就重金属而言，铝、铜、镉和汞在组织之间显示出统计学上的显著差异（p < 0.05）。确定从肌肉组织中获得的重金属浓度未超过国家和国际推荐限值；并且还发现每日摄入量未超过可耐受的每日摄入量。此外，在基于危害商数（THQ）的风险评估中，对儿童和成人至关重要的数值1未被超过。就公共卫生而言，发现在研究区域食用鲉鱼不存在任何风险。
