ABSTRACT Pearl oysters (Pinctada im

ABSTRACT Pearl oysters (Pinctada imbricata) were held in the laboratory and exposed to various levels of the heavy metals lead and zinc and the aliphatic hydrocarbons hexadecane and octacosane for 2 months. Individual oysters were followed over the course of the experiment, allowing specific calculation of total oyster growth (wet weight) and shell growth. Significant reductions in total oyster growth were observed when oysters were exposed to high concentrations (270
g L−1) of either zinc or lead. Exposure to the aliphatic hydrocarbons had no effect on total oyster growth. High concentrations of lead completely halted shell growth, the first demonstration of pollutant induced cessation of biomineralization in pearl oysters.Conversely, exposure to moderate levels of lead and the long-chain hydrocarbon octacosane resulted in significant increases in shell width growth. The results from this study indicate that P. imbricata is relatively tolerant of the selected pollutants and could be deployed within a remediative context in moderately polluted coastal areas.

摘要珍珠牡蛎（珠母玳瑁）在实验室中保持并暴露于各种级别的重金属铅和锌和脂肪烃十六烷和十八碳烷为2个月。个别牡蛎随访在实验的过程中，使总牡蛎生长（湿重）和壳的生长的特定的计算。当牡蛎被暴露于锌或铅的高浓度的（270？克L- 1）中观察到在总牡蛎生长显著减少。暴露于脂肪烃对总牡蛎生长没有影响。高浓度的铅完全停止外壳的增长，在珍珠oysters.Conversely，暴露于铅和长链烃二十八烷中等水平的生物矿化的污染物引起的停止的第一个示范导致壳宽的增长显著上升。这项研究的结果表明，P.玳瑁是相对宽容所选择的污染物，并且可以在中度污染沿海地区remediative范围内部署。

摘要珍珠牡蛎（合浦imbricata）举行了在实验室和遭受不同程度的重金属铅、锌和脂肪烃烷和二十八烷2个月。个别牡蛎随后在实验过程中，允许特定的计算总牡蛎生长（湿重）和壳生长。在总的牡蛎生长观察到显着减少当牡蛎暴露于高浓度（为我−1）或锌或铅。暴露于脂族烃的总牡蛎生长没有影响。高浓度的铅完全停止壳增长，污染物引起的珍珠牡蛎生物矿化戒烟的第一个示范。相反，暴露于中等水平的铅和长链碳氢化合物除导致壳宽生长显著增加。这项研究的结果表明，P. imbricata相对宽容的污染物，可以部署在一个remediative语境在中度污染的沿海地区。关键词：贝、牡蛎、污染、生物矿化、珍珠、金属、贝壳、水产养殖
