摘 要：
本文根据１９８９－１９９３年广东沿海１０个地点牡蛎体ＢＨＣ和ＤＤＴ的测定数据，论述了广东沿海牡蛎体ＢＨＣ和ＤＤＴ的变化趋势。牡蛎体ＢＨＣ和ＤＤＴ含量的空间分布格局，１９８９年以前呈珠江口海区明显高于粤东和粤西海区的特点，１９８９年以后三个海区间已无显著差异。牡蛎体ＢＨＣ和ＤＤＴ含量的时间变化趋势相似，均表现出１９８３—１９８９年和１９８９—１９９１年两个明显下降时段。１９９２年以后，牡蛎体中二者的含量均已降至检测限水平

摘 要：
Based upon the data of BHC and DDT concentrations in oyster Crassostrae rivularis collected from the coast of Guangdong provice during 1989-1993 and the related historical data, this paper discribed variation tendency of BHC and DDT concentrations in this organism Spatial distribution of BHC and DDT concentrations showed that before 1989 BHC and DDT concentrations in the oysters collected from the Pearl River estuarine coast were significantly higher than those in the oysters collected from the East Guangdong coast and West Guangdong coast, and after 1991 BHC and DDT concentrations in the oysters collected from these three coasts were not significantly different The temporal variation tendencies of BHC and DDT concentrations were similar, which showed that 1983-1989 and 1989-1991 were two significant decline periods After 1992 BHC and DDT concentrations in the oysters along the coast of Guangdong province decreased to detectable limit levels
