This study evaluates the potential human health risks of environmental pollutant loads carried by consumption of roach (Rutilus rutilus, Linnaeus, 1758), a bioindicator of environmental pollution from the Cyprinidae family in freshwater systems. We analyzed the concentrations of 26 potentially toxic elements (PTEs) in the muscle, gills, and liver, and 18 organochlorine pesticides (OCPs) in the muscle of roach originating from reservoirs (artificial lakes) with different uses (power generation and water supply) and anthropogenic impacts. Elemental concentrations were compared to maximum allowable concentrations and used to calculate pollution indices, including the metal pollution index and liver/muscle Hg index, health risk and benefit indices (target hazard quotient-THQ, target cancer risk-TR, Se:Hg, Na:K, and Ca:Mg ratios), and contributions of selected trace elements and macronutrients in roach meat. Additionally, the condition factor and histopathology were applied as biomarkers. The results showed that element accumulation varied between sites and tissues, with muscle tissue having the lowest pollution load and gills being the most exposed. OCP concentrations were below the maximum residue levels at all sites. Health risk and benefit indices determined no significant risks from the consumption of roach meat. The biomarker analysis showed diverse results with regard to pollutant accumulation. The highest anthropogenic pressure was observed in reservoirs used for power generation. Additionally, reservoirs at higher elevations were less polluted compared to reservoirs at lower elevations. Overall, the study suggests that the roach is a suitable bioindicator of environmental pollution.
本研究评估了食用拟鲤（Rutilus rutilus，林奈，1758年）所携带的环境污染物负荷对人类健康的潜在风险，拟鲤是淡水系统中鲤科的一种环境污染生物指示物。我们分析了来自具有不同用途（发电和供水）及人为影响的水库（人工湖）的拟鲤肌肉、鳃和肝脏中26种潜在有毒元素（PTEs）的浓度，以及肌肉中18种有机氯农药（OCPs）的浓度。将元素浓度与最大允许浓度进行比较，并用于计算污染指数，包括金属污染指数和肝脏/肌肉汞指数、健康风险和效益指数（目标危害商数 - THQ、目标癌症风险 - TR、硒：汞、钠：钾和钙：镁比率），以及拟鲤肉中选定微量元素和常量营养素的贡献。此外，将状况因子和组织病理学用作生物标志物。结果表明，元素积累在不同地点和组织之间存在差异，肌肉组织的污染负荷最低，鳃暴露程度最高。所有地点的OCP浓度均低于最大残留水平。健康风险和效益指数确定食用拟鲤肉不存在重大风险。生物标志物分析显示在污染物积累方面结果各异。在用于发电的水库中观察到最高的人为压力。此外，海拔较高的水库与海拔较低的水库相比污染程度较低。总体而言，该研究表明拟鲤是环境污染的合适生物指示物。
