摘要
突发性大气环境污染事件处于高发期，针对环境应急监测时效性强的特点，用便携式GC-MS快速测定大气中23种VOCs，探讨大气中VOCs测定在环境空气污染应急溯源中的应用。该方法在20．0μg／m^3～3200μg／m^3范围内线性良好，按采样1L计算，方法检出限为2．6μg／m^3～9．4μg／m^3，加标回收率为91．3％～103％，测定结果的RSD≤10．5％。将该方法用于突发性环境污染应急事件大气中VOCs的快速测定，通过对照企业特征污染物名录，能快速锁定污染源头。
The rapid determination of 23 volatile organic compounds( VOCs) in atmosphere by portable GC-MS and the application of VOCs analysis in the rapid tracing of atmospheric environmental pollution emergency were studied. The method detection limits of all the compounds were in the range of 2. 6 μg / m3to9. 4 μg / m3. The recoveries were in the range of 91. 3% to 103%,and RSD less than 10. 5%. The method is suitable for rapid determination of VOCs in emergent air pollution. Moreover,the pollution source could be sought out quickly according to air pollutant emission list of every enterprise.
