The Asian clam Corbicula fluminea exposed in situ for periods of 1, 5, 15 and 30 days along a stream which receives landfill leachate effluent showed increased Cr accumulation in gills and digestive gland, although Cr concentrations have been found to be low in sediment. Other metals such as Pb, Ni, Al and Cu were also analyzed but were found to accumulate in clam tissues in lower concentrations or without showing a consistent pattern. Thus, the accumulation of a single contaminant such as Cr is proposed to be used as a tool to assess exposure to a complex mixture such as landfill leachates.
在一条溪流中，亚洲河蚌 Corbicula fluminea 被原位暴露 1、5、15 和 30 天，尽管沉积物中铬的浓度较低，但在鳃和消化腺中积累的铬却有所增加。其他金属如 Pb、Ni、Al 和 Cu 也进行了分析，但在蛤组织中的积累浓度较低或没有表现出一致的模式。因此，建议将单一污染物（如 Cr）的积累用作评估复杂混合物（如垃圾渗滤液）暴露的工具。
