Heavy metals concentration (mercury, lead, cadmium, arsenic, copper, zinc and chromium) in tissues (muscles, liver, kidney and gonads) of Dalmatian barbelgudgeon, the nase, the souffie and brown trout, inhabiting waters of Busko Blato reservoir in Bosnia and Herzegovina, has been determined by atomic absorption spectrophotometry. The meat of the tested fish sorts does not contain elevated concentration of most analyzed heavy metals with exception of lead (higher than MAC in Italy, Germany and Denmark) and mercury (in muscles of brown trout higher than MAC in most countries). The lowest level of all heavy metals is always detected in gonads, with higher values in fry compared to milt for copper, zinc, chromium and arsenic. The highest copper concentration is observed in the liver from the souffie which is suggested as a suitable biomonitor for copper intoxication. In muscles of all fish sorts, lead was always present in much higher concentration than cadmium, while in kidneys of most fish sorts, lead and cadmium concentrations were similar. We showed that bioaccumulation of some heavy metals in the fish sorts analyzed is tissue and sex dependent. Also, we concluded that the small water exchange in reversible shallow reservoir does not induce elevated concentration of heavy metals in fish tissues inhabiting Busko Blato.
通过原子吸收分光光度法测定了生活在波斯尼亚和黑塞哥维那布斯科布拉托水库水域的达尔马提亚须鳅、雅罗鱼、苏氏雅罗鱼和褐鳟的组织（肌肉、肝脏、肾脏和性腺）中的重金属浓度（汞、铅、镉、砷、铜、锌和铬）。除铅（高于意大利、德国和丹麦的最大允许浓度）和汞（褐鳟肌肉中的汞含量高于大多数国家的最大允许浓度）外，受试鱼类的鱼肉中大多数分析的重金属浓度并未升高。在性腺中总是检测到所有重金属的最低水平，对于铜、锌、铬和砷，幼鱼中的含量高于精液中的含量。苏氏雅罗鱼肝脏中的铜浓度最高，这表明它是铜中毒的合适生物监测器。在所有鱼类的肌肉中，铅的含量总是远高于镉，而在大多数鱼类的肾脏中，铅和镉的浓度相似。我们表明，所分析鱼类中某些重金属的生物累积具有组织和性别依赖性。此外，我们得出结论，可逆浅水库中的小水量交换不会导致生活在布斯科布拉托的鱼类组织中重金属浓度升高。
