| 摘 要： | 对污灌土壤中 1 4种多环芳烃的分析表明 ,各灌区土壤中 PAHs的积累一般以渠首最高 ,渠中次之 ,渠尾含量与对照相当 .但在沈抚石油灌区上、中和下游土壤中均有PAHs的积累 .此外 ,水稻生长期污灌可明显增加土壤中 PAHs的总量 ,各单一污染物的增、减趋势有所不同 .

| Abstract: | The analysis of 14 polycyclic aromatic hydrocarbons(PAHs)in wastewater irrigated soils shows that in general,soils at up stream of irrigation channel have highest accumulation of PAHs,the second is the soils at the mid stream,and those at the down stream are similar with control.But in Shenfu area irrigated with petroleum wastewater,the accumulation of PAHs is found in all soils at up ,mid and down streams of irrigation channel.Application of wastewater during rice growing season can increase the total amount of PAHs in soil,the trend of increase or decrease of each pollutant is different. |
