摘要
采用GC和GC/MS检测手段,定量出汾河太原段有机污染物46种,其浓度在ppb～ppm范围。采用多污染物评价方法,就有机物对健康和生态的潜在危害进行定量评价,结果表明,6个采样点的健康总环境影响度TAS和4个采样点的生态总环境影响度TAS分别大于1,对人体健康和生态有潜在危害。酚类是主要的危害健康污染物。1,4-二氯苯,1,3-二氯苯,萘是主要的危害生态污染物。
46 kinds of organic pollutants in the range of ppb-ppm of concentration in Fenhe river of Taiyuan section have been analysed by means of the complementary techniques of GC and GC/MS for the quantificaton of organic compounds. The potential hazard for the human health and the ecology caused by these organics is assessed quantitatively by using multipollutant evaluation method. The results show that the health TAS and the ecology TAS are more than 1 respectively in six sampling sites and 4 sampling sites. Phenols is the primary pollutant for the human health.1,4- (or 1, 3-)dichlorobenzene and naphthalene are the primary pollutant for the ecology.
