The concentrations of As, Cd, Hg, Pb and Zn have been determined in oysters and sediments from the Lynher Estuary, U.K. The sediments contained high levels of Cu, Fe, Pb and Zn probably associated with run off from a metalliferous catchment area and high Hg associated with a local sewage input. In contrast, the analyses of the oyster tissue showed that only Cu and Zn were concentrated in the flesh. The majority of samples contained coliform bacteria in excess of 1000 organisms per ml of tissue. It is concluded that the quality of the oysters from this fishery was limited by the bacteriological cleanliness rather than toxic metal content.
已对英国林赫河口的牡蛎和沉积物中的砷、镉、汞、铅和锌浓度进行了测定。沉积物中含有高含量的铜、铁、铅和锌，这可能与来自一个含金属集水区的径流有关，而高汞含量则与当地的污水排放有关。相比之下，对牡蛎组织的分析表明，只有铜和锌在肉中富集。大多数样本每毫升组织中的大肠菌群细菌数量超过1000个。得出的结论是，该渔场牡蛎的质量受细菌清洁度而非有毒金属含量的限制。
