【摘要】 本文于1994年11月用气相色谱法研究了旱季珠江口区环境中BHC和DDT的含量与分布。结果表明，表层海水BHC含量为0.187μg/L，DDT为0.080μｇ/L；底层海水BHC为0.117μｇ／L，DDT为0.506μｇ／L。沉积物BHC为11.15×10－9（干），DDT为33.46×10－9（干）。海水中的盐度、DO、C更多还原

【Abstract】 The project is a part of CRP organized by IAEA and FAO on the distribution,fate and effect of pesticide on biota in the tropical marine environment.The results divided into several special subject.In Oct.1994,11 stations (Fig.1) in the Zhujiang Estuary were set up.The surface sea water,bottom sea water and the surface sediment were sampled. The result showed that the average of BHC was 0.087 μg/L in the surface water, 0.117 μg/L in the bottom water,in the surface water,DDT was 0.080 μg/L ,bottom water 0.506 μg/L .The average of BHC in the surface sediment was 11.15×10 -9 (dry),DDT 33.46×10 -9 (dry).The influences of salinity,DO and COD on the contents of BHC and DDT havent been discovered in the seawater.It can be illustrated that the distribution regular of BHC and DDT reflects the hydrodynamic character in Zhujiang Estuary.更多还原
