摘要
用实验生态学方法,观察浓度为0．1、1、10ng／dm3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．
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/dm^3 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 compaired to control, and the activity of alkalinephosphatase in 1,10 ng/dm^3 groups was induced with prolonged exposure. The activity of aaciphosphatase, to TBT. The results suggested that Na^＋、K^＋-ATPase tot TBT pollution. Na^＋、K^＋-ATP ase were inhibited after exposure activity would be a potential biomarker to monitor TBT pollution.
