Abstract
研究了镉(Cd)、铜(Cu)2种重金属单一暴露下菲律宾蛤仔(Ruditapes philippinarum)肝胰腺和鳃组织内的重金属富集特征和抗氧化酶活力变化特点。结果表明,蛤仔肝胰腺与鳃对Cd、Cu的富集量随重金属浓度与暴露时间的增加而增大,具有明显的浓度效应与时间效应;菲律宾蛤仔对Cd的富集能力高于Cu,且肝胰腺中重金属的蓄积量高于鳃;蛤仔肝胰腺和鳃组织中超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GPx)和谷胱甘肽硫转移酶(GST)活力在暴露的某些时段被显著诱导(P<0.05),但随暴露时间延长或重金属浓度增加,SOD和GST活力则被显著抑制(P<0.05),而GPx活力随暴露时间延长..
