The concentrations of six metals (Hg, Cd, Cu, Pb, Cr and Zn) individual total metal load (IMBI) values and its relation to condition index were determined in water, sediment and tissues of crab (Callinectes sapidus) and two fish species (Mugil cephalus and Anguilla anguilla) inhabiting Köyceğiz Lagoon System. The average distribution of the IMBI values ranged from 0.033 to 0.265. Distribution patterns of IMBI in species follow the sequence: A. anguilla > M. cephalus > C. sapidus. Results showed that there are positive relationships between species sizes and metal levels in most cases. The concentrations of Pb in muscle in the three studied species were in all cases considerably higher than the maximum levels set by law. Average Cd, Cu and Zn values in M. cephalus were also higher than the limits proposed for fish by FAO/WHO, EC and TFC. Therefore, the human consumption of all analysed species is not recommended.
测定了栖息在科伊切吉兹泻湖系统中的螃蟹（Callinectes sapidus）以及两种鱼类（ Mugil cephalus和Anguilla anguilla）的水、沉积物和组织中六种金属（汞、镉、铜、铅、铬和锌）的浓度、个体总金属负荷（IMBI）值及其与状况指数的关系。IMBI值的平均分布范围为0.033至0.265。IMBI在物种中的分布模式顺序为：欧洲鳗鲡＞鲻鱼＞美味优游蟹。结果表明，在大多数情况下，物种大小与金属含量之间存在正相关关系。在所研究的三种物种中，肌肉中的铅浓度在所有情况下均大大高于法律规定的最高水平。鲻鱼中镉、铜和锌的平均含量也高于粮农组织/世界卫生组织、欧盟委员会和土耳其食品法典委员会为鱼类建议的限值。因此，不建议人类食用所有分析过的物种。
