中文摘要：
对太原市污灌区进行系统的野外调查,采集了污灌水样、浅层孔隙地下水样以及农田中7个不同深度的土样,使用GC、GC/MS等仪器对样品进行定性定量分析。结果表明,污水有机污染成分多且特别复杂,主要污染物为增塑剂,如酞酸酯类、粪臭素、甾醇类、多环芳烃等;土壤中多环芳烃污染最严重,附近的浅层地下水也检测到相关的多环芳烃类化合物,但距离污灌区较远或者水位较深的地下水有机污染程度相对较轻。研究成果为灌区进行合理灌溉规划提供了科学的参考依据。
英文摘要：
We made a systematic field investigation on sewage irrigation area in Taiyuan City.The samples of sewage irrigation water,shallow pore water and soil of farmland in seven different depths were collected.GC、GC/MS and other instrument were used to make qualitative and quantitative analysis on samples.The results show that the organic pollution components are complicated and large in amount.The main pollutants are plasticizer such as phthalo-ester compound,skatole,steroles and polycyclic aromatic hydrocarbons.The soil is severely polluted by polycyclic aromatic hydrocarbons,which is detected in the shallow pore water nearby;however,the underground water which is relatively far from the sewage area or in deeper level is relatively less polluted.The results provide a scientific reference for the reasonable irrigation schedule in sewage area.
