摘要/Abstract

摘要： 采用半静态水质接触染毒法，将太平洋牡蛎分别暴露在阿特拉津质量浓度为10 μg/L和100 μg/L的海水中，研究阿特拉津在太平洋牡蛎体内的蓄积特征、组织分布和消除规律。结果表明，不同暴露质量浓度下，各组织中阿特拉津含量在3～7 d达到平衡，半衰期为0.20～0.32 d，生物富集系数为1.68～3.46 mL/g，鳃和内脏团是太平洋牡蛎的主要蓄积靶组织，而闭壳肌中阿特拉津含量最低。太平洋牡蛎对阿特拉津的消除能力随暴露质量浓度的增大而增强，各组织中阿特拉津的含量随净化时间呈指数下降，净化1 d后的消除率为90.1%～97.1%，其主要代谢途径推测为鳃的作用。

Abstract: The accumulation characteristics, tissue distribution and elimination pattern of atrazine in Crassostrea gigas were studied by the semi-static water contact poisoning method after being exposed to seawater containing different atrazine concentrations of 10 and 100 μg/L. The results showed that for each exposure concentration, the content of atrazine in each tissue of C. gigas reached equilibrium between days three and seven days after being switched to clean seawater. Moreover, the half-life time of atrazine in C. gigas were 0.20–0.32 days with a bioconcentration factor (BCF) ranging from 1.68 to 3.46 mL/g. The gill and visceral mass were the major target tissues for the accumulation of atrazine, and the content of atrazine in the adductor muscle was the lowest. The elimination capacity of C. gigas for atrazine increased with increasing exposure concentration. Meanwhile, the content of atrazine in each tissue decreased exponentially with depuration time. The elimination rate of atrazine was 90.1%–97.1% after depuration for one day, and atrazine might be metabolized through the gill.
