| 中文摘要 |
| 使用充填有Ｔｅｎａｘ、碳分子筛和硅胶的多层热解吸金属管，以０．２０Ｌ／ｍ ｉｎ 的流速采集垃圾填埋场空气样品，以Ｔｅｋ－ｍ ａｒ３０００／６０３２ 和ＨＰ５８９０／５９７２ ＧＣ－ＭＳＤ 组合仪器进行分析，共检测出６３ 种挥发性有机污染物（ＶＯＣｓ），其中有１６ 种为ＵＳＥＰＡ 优先控制污染物；通过对大多数化合物进行定量分析所得的结果表明，以苯及其衍生物含量最高，为７．９４～２０２．５５μｇ／ｍ3；其它氯代有机物含量虽然相对较低，但由于它们的毒性，因此其对环境的影响亦不容忽视． |
| 英文摘要 |
| The sample was collected at a rate of 0.20 L/min from a landfill gas using a multi layer heat desorption tube filled in three different polarities solid sorbents.The qualitative and quantitative determination of trace volatile organic compounds(VOCs) was carried out through the combined purge and trap and GC MS system.63 of the VOCs including 16 of USEPA priority controlled pollutants were detected.Benzene and its derivatives have the highest concentrations range of 7.94～202.55 μg/m3.The other pollutants such as chlorinated organic compounds,though there were a relatively low concentration,should not be overlooked due to their toxic effects. |
