摘要
采用预浓缩仪-气相色谱/质谱联用系统对上海某工业区的6个点位进行一年的监测。结果表明:该地区共检出46种挥发性有机物,平均VOCs浓度为228.91μg/m3,其中含量最高的为酯类55.97μg/m3、卤代烷烃55.15μg/m3、苯系物41.95μg/m3。苯系物中甲苯含量最高。分析该地区VOCs时空变化规律发现12月质量浓度最高、10月最低,季节变化规律为冬>秋>春>夏。居民敏感点和清洁对照点的VOCs浓度较低,某化工企业点位浓度最高、其卤代烷烃污染较为严重。
This research monitored 6 points of a certain industry park in Shanghai for one year by preconcentrator- GC- MS system. Results showed that 46 kinds of VOCs were detected. The average concentration of VOCs was 228. 91 μg / m^3,and the highest three kinds were esters 55. 97 μg / m^3,halogenated alkane 55. 15 μg/m^3 and benzene series 41. 95 μg / m^3. Methylbenzene owned the highest concentration in benzene series. Study on the temporal and spatial variation found that VOCs＇ concentration was highest on December while lowest on October. The season variation indicated winter autumn spring summer. The VOCs of the resident sensitive point and clean control point were lower. While the Chemical Plant point owned the highest VOCs,whose halogenated alkane pollution was more serious.
