垃圾填埋场空气中微量挥发性有机物的组成和分布

 通过对广州一垃圾填埋场大气中微量挥发性有机污染物（VolatileOrganic Compounds,VOCs）的定性和定量分析，研究了其中部分VOCs的浓度分布规律并探讨了其对周围居民区环境的影响．结果表明，在检测到的 60种VOCs中，有 17种USEPA优先控制污染物，苯及烷基苯化合物浓度最高，在2.54～1508.48μg/m³之间；通过对比填埋场内外空气中 VOCs的浓度水平发现，填埋场内空气中各VOCs的浓度比场外的高，在地势较低的地方空气中各VOCs的浓度比地势较高的地方浓度高，这些VOCs对周围居民区的环境没有明显影响。

Composition and distribution of trace volatile organic compounds in the air from the field landfill of Guangzhou

The qualitative and quantitative determinations of the trace volatile organic compounds (VOCs) in the air from the landfill field of Guangzhou, China have been carried out. The VOCs concentration distribution and their effects on residential environment have also been discussed. The results showed that there were 17 USEPA priority-controlled pollutants in 60 irate VOCs detected. Benzene and alkylbenzenes have the highest concentrations ranging from 2.541508.48g/m3. The concentrations of VOCs in air from the field were higher than those in the air outside the field. Higher VOCs concentrations were detected on the lower area where VOCs were easy to accumulate. No obvious pollution effects on ambient residential environment were found.
