摘要(Abstract)：
文章建立了PCA源解析和PCDDs/PCDFs比值相结合的源解析方法,对我国福建省某工业园区生活垃圾焚烧厂(MSWI)周围的环境空气和土壤中四氯八氯代二恶英(2,3,7,8-PCDD/Fs)含量和分布特征进行了分析,结果表明,在环境空气和土壤中PCDD/Fs含量变化范围分别为0.437 4八氯代二恶英(2,3,7,8-PCDD/Fs)含量和分布特征进行了分析,结果表明,在环境空气和土壤中PCDD/Fs含量变化范围分别为0.437 40.936 4 pg/m0.936 4 pg/m3(0.0333(0.0330.046 pg ITEQ/m0.046 pg ITEQ/m3)和265.533)和265.53598.07 ng/kg(1.424598.07 ng/kg(1.4242.231 ng I-TEQ/kg).此外,土壤样品中08CDD单体在PCDD/Fs中的贡献率变化范围为93.18%2.231 ng I-TEQ/kg).此外,土壤样品中08CDD单体在PCDD/Fs中的贡献率变化范围为93.18%97.51%.分别采用PCA源解析和环境空气、土壤中PCDDs/PCDFs比值分析,结果均说明K4点外不受热源影响,其他取样点都受到热源的影响.最后计算17种单体的逸度值分析PCDD/Fs在土壤和环境空气中传递情况,得出了PCDD/Fs净含量由环境空气传递到土壤中的重要结论.
