Concentrations of As, Cu, Fe, Hg, Pb and Zn and activity concentrations from 234,238U and 210Po in water, fillet, liver and gills were determined in three stocked fish species from the Luis L. Leon reservoir, located in Northern Mexico. The considered species were Lepomis cyanellus, Cyprinus carpio and Ictalurus furcatus. 238U and 234U activity concentration (AC) in fillet samples showed values of 0.007-0.014 and 0.01-0.02 Bq∙kg-1 wet weight (ww), respectively. Liver samples for L. cyanellus, C. carpio and I. furcatus present 210Po AC of 1.16-3.26, 0.70-1.13 and 0.93-1.37 Bq∙kg-1 ww. Arsenic, mercury and lead concentration intervals in fillet samples were 0.13-0.39, 0.005-0.126 and 0.009-0.08 mg∙kg-1 ww, respectively, while in gill samples they were 0.11-0.43, 0.002-0.039 and 0.02-0.26 mg∙kg-1 ww. The elemental Bioaccumulation Factor (BAF) for fish tissues with respect to their concentrations in water was determined. L. cyanellus showed the highest BAF values for As and total U, being BAFAs = 37 and 40 L∙kg-1 in fillet and gills, respectively, and BAFU total = 1.5 L∙kg-1 in fillet. I. furcatus showed the highest BAF values for Hg and Pb, being BAFHg = 40 and 13 L∙kg-1 in fillet and gills, and BAFPb = 6.5 and 22 L∙kg-1 in fillet and gills, respectively. Some metal(loid) concentrations are slightly higher than European regulations for fish fillets. The difference in concentrations of metal(loid)s in fillet among the studied species is probably due to their differences in diet and habitat.
在位于墨西哥北部的 Luis L. Leon 水库中，对三种养殖鱼类（蓝鳃太阳鱼、鲤鱼和斑点叉尾鮰）的水、鱼片、肝脏和鳃中的砷（As）、铜（Cu）、铁（Fe）、汞（Hg）、铅（Pb）和锌（Zn）浓度以及 234U、238U 和 210Po 的活度浓度进行了测定。鱼片样本中 238U 和 234U 的活度浓度（AC）分别为 0.007-0.014 和 0.01-0.02 Bq·kg-1 湿重（ww）。蓝鳃太阳鱼、鲤鱼和斑点叉尾鮰的肝脏样本中 210Po 的 AC 分别为 1.16-3.26、0.70-1.13 和 0.93-1.37 Bq·kg-1 ww。鱼片样本中砷、汞和铅的浓度范围分别为 0.13-0.39、0.005-0.126 和 0.009-0.08 mg·kg-1 ww，而在鳃样本中分别为 0.11-0.43、0.002-0.039 和 0.02-0.26 mg·kg-1 ww。确定了鱼类组织相对于其在水中浓度的元素生物积累因子（BAF）。蓝鳃太阳鱼的 As 和总 U 的 BAF 值最高，分别为鱼片和鳃中的 37 和 40 L·kg-1，以及鱼片中的 1.5 L·kg-1。斑点叉尾鮰的 Hg 和 Pb 的 BAF 值最高，分别为鱼片和鳃中的 40 和 13 L·kg-1，以及鱼片和鳃中的 6.5 和 22 L·kg-1。一些金属（类）的浓度略高于欧洲对鱼片的规定。在所研究的物种中，鱼片中外源金属（类）的浓度差异可能是由于它们的饮食和栖息地的不同。
