摘要
将泥鳅暴露于不同浓度的废旧干电池污染液中,于48 h、72 h测定其超氧化物歧化酶(SOD)及过氧化氢酶(CAT)的活性,结果显示低浓度、短时间内SOD、CAT活性被诱导,随着废旧干电池污染液浓度的增大和暴露时间的延长,酶活性被抑制.因此SOD、CAT可作为生物标志物来监测水生态系统的污染.
Loaches were exposed to different extent polluted water with waste cells and the SOD and CAT activity in animals was detected after 48 hours and 72 hours exposed. The result shows that SOD and CAT activity was induced by exposing to low extent polluted water in short time, which was restrained when the pollution extent of water was higher or the exposing time longer. The conclusion is that SOD or CAT can be used as biomarkers in monitoring pollution of water ecosystem.
