Turkey ranked first in sea bass farming in Europe, and almost all extra-EU seabass come from this country. The share of Turkish sea bass in the fish consumption of Europeans has increased significantly, and assessment of potential health risks of trace metals via sea bass, cultured by Turkey, became important. The Netherlands is the main buyer of the Turkish sea bass. Therefore, potential health risks were determined for Turkish and Dutch consumers. In the study, the concentrations of lead (Pb) and mercury (Hg) were below the limits, but the level of cadmium (Cd) was above the guidelines, in spring and winter. Dietary intake and potential health risk were found higher for the Dutch consumer, but all target hazard quotients (THQs) and total THQ (TTHQ) values were well below 1, showing no significant health risk due to the consumption of sea bass, cultured and exported by Turkey. It was determined that these sea basses can be safely consumed in quite high amounts, such as at least 31 meals a month. Se/Hg molar ratios were all above 1 and selenium health benefit values (Se-HBVs) were positive, indicating that selenium (Se) had a protective effect on Hg toxicity and positive health effects. Considering the average annual intake in Turkey and Netherlands, the consumption of sea bass, cultured by Turkey, is safe. Since the risk levels of communities may differ due to their eating habits, it is important to determine the public health impacts of the international fish trade.
土耳其在欧洲鲈鱼养殖方面排名第一，几乎所有来自欧盟以外的鲈鱼都来自这个国家。土耳其鲈鱼在欧洲人鱼类消费中的份额显著增加，因此通过土耳其养殖的鲈鱼评估痕量金属的潜在健康风险变得很重要。荷兰是土耳其鲈鱼的主要买家。因此，确定了土耳其和荷兰消费者的潜在健康风险。在这项研究中，春、冬两季的铅（Pb）和汞（Hg）浓度均低于限量，但镉（Cd）水平高于指导值。研究发现，荷兰消费者的膳食摄入量和潜在健康风险更高，但所有的目标危害系数（THQ）和总目标危害系数（TTHQ）值均远低于 1，表明由于食用土耳其养殖和出口的鲈鱼，不存在显著的健康风险。研究表明，这些鲈鱼可以安全食用，每月至少 31 餐。硒/汞摩尔比均高于 1，硒健康效益值（Se-HBVs）为正值，这表明硒（Se）对汞毒性具有保护作用，对健康有积极影响。考虑到土耳其和荷兰的年平均摄入量，食用土耳其养殖的鲈鱼是安全的。由于不同社区的饮食习惯不同，风险水平可能存在差异，因此确定国际鱼类贸易对公共健康的影响非常重要。
