2011年夏、秋两季，在法国贝尔福特的Etueffont垃圾填埋场排水系统池塘中，测定了水、沉积物和普通roach （Rutilus Rutilus）鱼类组织（鳃、肝脏、肌肉和骨骼）中镉、铬、铜、铁、铅、锰、镍、锶和锌的浓度。除铅外，夏季水体中金属含量较高，秋季沉积物中金属含量较高。在鱼类组织中，平均金属浓度的变化趋势是：Zn > Fe > Sr > Mn > Cu > Cr > Cd近似于Pb近似于Ni。鳃和肝脏比肌肉和骨骼显示出更大的积聚，而骨骼则受到已知与钙相互作用的金属（如锰、锶和锌）浓度的影响。这些组织积累了铁、锌、铜、锰和锶等必需金属，这些金属在沉积物和水中的含量也很高。然而，蟑螂组织不太适合接触Cd、Pb和Ni，因为沉积物和水中的镉、Pb和Ni含量都很高，但在鱼类组织中根本没有检测到镉、Pb和Ni。因此，物理化学和生物分析的结合是筛选整体环境的好方法。因此，蟑螂可能是一种有用的生物指标，用于评估金属污染，尽管这个问题需要进一步的研究。(C) 2014 Elsevier B.V.版权所有
Concentrations of cadmium, chromium, copper, iron, lead, manganese, nickel, strontium and zinc were determined in water, sediment and fish tissues (gills, liver, muscle and bones) of the common roach (Rutilus rutilus) in the Etueffont landfill draining system pond (Belfort, France), during summer and autumn in 2011. Metal concentrations in the water were higher in summer, whereas in sediment they were higher in autumn, except for lead. In fish tissues, the trend in the mean metal concentrations was: Zn > Fe > Sr > Mn > Cu > Cr > Cd approximate to Pb approximate to Ni for gills and muscle. Gills and liver showed greater accumulation than muscle and bones, while bones were subjected to concentrations of metals known to interact with calcium such as Mn, Sr and Zn. The tissues accumulated essential metals such as Fe, Zn, Cu, Mn and Sr, which are also found in high concentrations in both sediment and water. However, roach tissues are less suitable for Cd, Pb and Ni exposure, as high levels were measured in both sediment and water but not detected at all in fish tissues. Thus, a combination of physico-chemical and biological analysis is a goodway to screen overall environmental circumstances. The roach may therefore be useful as a bioindicator for assessment of metal pollution, though this issue requires further study. (C) 2014 Elsevier B.V. All rights reserved.
