摘要
采用毒性实验方法研究水体中铬离子 Cr6+(、、、、 mg L-1)胁迫1、3、5、7、9 d后对拟穴青蟹组织
器官中ATPase、SOD活性的影响,以未添加Cr6+的自然海水组为对照组. 结果表明,拟穴青蟹鳃中Ca 2+-ATPase、Na+,K+-
ATPase活性在 Cr 6+暴露1 d后即被显著抑制(P<),随胁迫时间延长,Cr 6+又可诱导拟穴青蟹鳃中 Ca 2+-ATPase、
Na+,K+-ATPase活性升高. Cr6+胁迫下拟穴青蟹鳃、肝胰腺、肌肉中SOD活性均可被显著诱导升高(P<),其中尤以鳃
中SOD活性受影响更大. 可见铬胁迫对拟穴青蟹生理生化影响显著. 图2 表1 参36
