摘　　要：为研究环境空气中挥发性卤代烃的污染特征,在广东省珠三角某工业城镇中的5个功能区设置采样点进行了挥发性卤代烃的监测。采用气相色谱/质谱联用系统共定性定量检测出23种挥发性卤代烃,其中检出率为100%有二氯甲烷、1,2-二氯乙烷等11种卤代烃,前5种挥发性卤代烃的平均浓度从高到低依次为:二氯甲烷>1,2-二氯乙烷>1,2-二氯丙烷>四氯化碳>1,1,2-三氯-1,2,2-三氟乙烷。该镇工业园区卤代烃的总浓度明显高于居住区和教学区,二氯甲烷浓度远高于广州、开平等其他地区。In order to study the pollution characteristics of volatile halogenated hydrocarbons in ambient air,the monitoring of volatile halogenated hydrocarbons was carried out at five functional zones in an industrial town in the Pearl River Delta of Guangdong Province.A total of 23 volatile halogenated hydrocarbons were detected by gas chromatography/mass spectrometry.The detection rate was 100%.There were 11 halogenated hydrocarbons such as dichloromethane and 1,2-dichloroethane.The average concentration of volatile halogenated hydrocarbons from high to low is:dichloromethane>1,2-dichloroethane>1,2-dichloropropane>carbon tetrachloride>1,1,2-trichloro-1,2,2-trifluoroethane.The town industry.The total concentration of halogenated hydrocarbons in the park is significantly higher than that in residential areas and teaching areas.The concentration of methylene chloride is much higher than that in other areas of Guangzhou and Kaiping.
