摘要
本文采用较快速、简便的方法,用GC/ECD对珠江三角洲几个城市中的污水及深圳河、大沙河中的有机氯化合物进行了初步探查及半定量分析,结果表明,几种有机氯农药尽管已停止生产多年,但在污水及河水中仍有残留,其中DDT含量在0.007～0.230ppb范围内;BHC在0.006～0.380ppb范围内。氯苯类化合物及PCBs在污水及河水中也均可检出。
The GE/ECD approach,which is a simple and swift method ,is used tocarry out the investigation into and semi—quantity analysis of organic chlorine compounds in water of cities in Zhu Jiang delta region. It is dicovered that organic chlorine compound residue is still exist in water even though there is no more production of agricultural pesticides which contain organic chborine. It is fourd that the DDT concentration is within the range of 0. 007 — 0. 230ppb,BHC concentration is within the range of 0. 006 — 0. 380ppb. The chlorine benzene compounds and PCBs is also discoved in the water of the region.
