利用GC/MS/DS系统和保留指数,对运河(常州段)悬浮物和底泥上的有机污染物进行了概要分析。结果显示,该段河流的悬浮物和底泥上含有直链烷烃、多环芳烃、直链醛酮、烷基磺酸、苯酯类、邻苯二甲酸酯类、硝基联苯、二苯砜、醇类、羧酸类等有机污染物和致癌物。河流悬浮物和底泥上所鉴定出的有机污染物数量相当,浓度范围基本一致。同一段面底泥上的浓度稍高于悬浮物上的浓度;枯水期悬浮物上的浓度稍高于丰水期悬浮物上浓度。
Using the GC / MS / DS system and the retention index, an overview of organic pollutants in suspended solids and sediments of the canal (Changzhou section) was conducted. The results show that the suspended sediment and sediment in the section of the river contain straight-chain alkanes, polycyclic aromatic hydrocarbons, straight-chain aldehydes and ketones, alkyl sulfonic acids, phenyl esters, phthalates, nitrobiphenyl, Sulfone, alcohols, carboxylic acids and other organic pollutants and carcinogens. The amount of organic pollutants identified on suspended sediments and sediments of rivers is quite similar, and the concentration ranges are basically the same. The same section of the surface sediment concentration slightly higher than the concentration of suspended solids; dry season suspended solids slightly higher than the concentration of suspended solids during the wet season.
