The effect of linear alkylbenzene sulphonate (LAS) on copper and lead bioaccumulation in Ruditapes philippinarum was studied. The in vitro and in vivo effect of LAS on acid and alkaline phosphatase activities was also examined. For lead, significant differences (P<0.01) were observed between organisms exposed to lead and to the mixture of LAS and lead. In the case of copper, these differences were only significant in the digestive gland (P<0.05). In vitro acid phosphatase was inhibited by LAS and the mixture of LAS with copper showed the effect of decreasing the enzymatic activity. Nevertheless, in vivo no significant differences in the digestive gland and gills (P < 0.05) were observed. 相似文献
