The concentrations of ten metals in rainbow trout (Oncorhynchus mykiss) farmed in the Karakaya Dam Reservoir (Turkey) on the Firat River were determined. The metal concentrations in rainbow trout did not exceed the maximum permissible levels. Biomagnification factors (BMF) of ten metals were <1, indicating that these metals were not biomagnified. The estimated daily intake (EDI) of each metal was much lower than the respective tolerable daily intake (TDI). The target hazard quotient (THQ) for individual metal and total THQ for combined metals were lower than 1, indicating no health risk for consumers due to the intake of either individual metal or combined metals. The cancer risk (CR) value for toxic inorganic As was below 10, indicating no carcinogenic risk. According to the calculated maximum allowable consumption rates (CR), an adult may safely consume 28 meals of rainbow trout from the dam reservoir per month with no adverse carcinogenic and non-carcinogenic health effects. According to these results, the consumption of rainbow trout farmed in this dam reservoir is completely safe for human health.
测定了在幼发拉底河的卡拉卡亚大坝水库（土耳其）养殖的虹鳟鱼（Oncorhynchus mykiss）中十种金属的浓度。虹鳟鱼中的金属浓度未超过最大允许水平。十种金属的生物放大因子（BMF）<1，表明这些金属没有生物放大。每种金属的估计每日摄入量（EDI）均远低于各自的可耐受每日摄入量（TDI）。单个金属的目标危害系数（THQ）和组合金属的总 THQ 均低于 1，表明由于摄入单个金属或组合金属，消费者没有健康风险。有毒无机砷的致癌风险（CR）值低于 10，表明不存在致癌风险。根据计算出的最大允许消费率（CR），成年人每月可以安全地食用来自大坝水库的 28 餐虹鳟鱼，而不会产生致癌和非致癌的健康影响。根据这些结果，食用该大坝水库养殖的虹鳟鱼对人类健康是完全安全的。
