摘要
为了监测八十年代末以来广东沿海海洋环境中Ｈｇ的变化趋势，作者利用海洋双壳类牡蛎作为指示生物，测定了自１９８９年至１９９３年间广东沿海１４个观测站位的牡蛎体中的Ｈｇ。结果表明，牡蛎体中的Ｈｇ呈逐年下降之势，即从１９８９年的０．０４６×１０－６降为１９９３年的０．０２８×１０－６。Ｈｇ的主要化学形态为有机汞，作者还对Ｈｇ的季节变化特点。
In order to monitor the change tendency of mercury in Guangdong coastal environment since the late 1980's, we used marine bivalves as biological indicator, and analyzed the concentrations of mercury in oyster collected from 14 stations along Guangdong coast The result shows that the mercury in oyster declined annually from 1989's 0 046ppm to 1993's 0 028ppm And the major chemical speciation was organic mercury The seasonal and spatial change characters were also studied
