摘  要：
在对浙东沿海某典型固废拆解区的水-土壤-农作物系统进行系统调查和分析的基础上,重点探讨了污水灌溉对土壤多氯联苯(PCBs)含量的影响程度,并通过建立数学模型,对污灌区土壤PCBs含量进行了预测。结果表明,研究区土壤、水体、底泥乃至农作物均检测出相当水平的PCBs,对当地的生态安全影响较大;经因子分析和对比分析发现,约有67.3%的土壤PCBs污染是由污水灌溉引起,污水灌溉对土壤污染的影响显著;在现有农田灌溉模式不变的情况下,污灌区的土壤PCBs含量将呈上升趋势,50a后含量将增加1倍。

摘  要：
In this paper,water,soil and crops were investigated and analyzed systematically in a typical solid waste's dumping and unpacking site of eastern Zhejiang Province,China. On the basis of the investigation,impact degree of wastewater irrigation on contents of polychlorinated biphenyls(PCBs) in soils was discussed deeply. The contents of PCBs in the soils of wastewater irrigation area were predicted through a mathematical model built. The results showed that contents of PCBs in the soil,water,sediment and crops were all in a high level,which impaired ecological security. Based on the results of factor analysis and comparative analysis,the impact degree of wastewater irrigation on the PCBs pollution of soil was significant,which contributed PCBs of 67.3% to the soil. If the current irrigation mode was constant,the PCBs contents of soil in the wastewater irrigation area would increase drastically,whose contents would be doubled after fifty years.
