摘要
研究了Hg2+对日本沼虾的急性毒性,在24℃下,测定了Hg2+对日本沼虾(Macrobrachiumnipponnensis)的24,48,72和96 h的LC50值分别为60.2,52.4,47.6和38.0μg/L.在几个Hg2+质量浓度梯度胁迫下,超氧化物歧化酶(SOD),Na+-K+-ATPase,谷丙转氨酶(GPT)、谷草转氨酶(GOT)活性均受到不同程度的抑制,随Hg2+质量浓度的升高,抑制作用越明显.
The toxic effects of Hg^2＋ on the shrimp（Macrobrachium nipponnensis） were studied. At 24,48, 72,96 h the median lethal concentrations of Hg^2＋ to the shrimp were 60.2,52.4,47.6 and 38.0 μg/L at 24℃ respectively. At the different concentrations of Hg^2＋ , the activities of SOD, Na^＋ -K^＋ -ATPase, GPT and GOT were decreased along with the rising concentration of Hg2^＋ .
