| 摘 要： | 用实验生态学方法，观察浓度为0．1、1、10ng／dm^3的三丁基锡暴露2、8、20d以及恢复7、20d后对文蛤外套膜酸性磷酸酶、碱性磷酸酶以及Na^＋、K^＋-ATP酶活性的影响．结果表明各浓度组的三丁基锡在暴露早期（2d），外套膜中酸性、碱性磷酸酶和Na^＋、K^＋-ATP酶活性与对照组比较没有显著差异，随着暴露时间的延长，高浓度的TBT暴露对AKP表现出激活作用，对ACP和Na^＋、K^＋-ATP酶活性则具有抑制作用．结果显示Na^＋、K^＋-ATP酶可作为有机锡暴露的生物标志物．

| Abstract: | The effects on alkaline phosphatase, aaciphosphatase and adenosine triphosphatase activities in mantle of Meretrix meretrix exposed to tributyltin (TBT) at environmental levels (0. 1,1, 10ng/dm3 as Sn) for 2, 8, 20 days and recovered for 7 and 20 days in experimental condition were evaluated. The results showed that the activity of alkalinephosphatase, aaciphosphatase and Na+ , K+ -ATPase were not significantly differences at earlier period (2days) exposure to tributyltin com-paired to control,and the activity of alkalinephosphatase in 1,10 ng/dm3 groups was induced with prolonged exposure. The activity of aaciphosphatase, Na + , K+-ATP ase were inhibited after exposure to TBT. The results suggested that Na+, K+ -ATPase activity would be a potential biomarker to monitor TBT pollution. |
