摘　　要：利用SPI-MS 2000在线走航监测系统对岳阳地区的11个区域进行了22d的监测分析。结果表明,岳阳地区整体ΣVOCs均值浓度为174μg/m^(3),VOCs组分占比从高到低依次为芳香烃、烯烃、含氧含氮烃、烷烃、有机硫、卤代烃。走航区域内共发现46个异常点,其中加油站油气挥发问题普遍存在。此外云溪区异常点位较多,ΣVOCs峰值浓度较高,受化工行业影响较大。对臭氧生成贡献较大的行业主要是涂料、油墨制造和石化。各行政区域中存在问题的企业和污染程度存在较大差异,可根据污染特征进行针对性管控。The SPI-MS 2000 on-line navigation monitoring system was used to monitor and analyze 11 areas in Yueyang area for 22 days.The results showed that the averageΣVOCs concentration in Yueyang area was 174μg/m^(3),and the components of VOCs were aromatic hydrocarbons,olefin,Oxygen and nitrogenous hydrocarbons,alkane,or-ganic sulfur and halogenated hydrocarbons in descending order.A total of 46 abnormal points were found in the navi-gation area,among which oil and gas volatilization at gas stations was common.In addition,there were many abnor-mal points in Yunxi area,ΣVOCs peak concentration is high,which is greatly influenced by the chemical industry.In-dustries that contribute significantly to ozone formation are mainly coatings,ink manufacturing and petrochemicals.Problem enterprises and pollution degree vary greatly among administrative regions,and targeted control can be car-ried out according to pollution characteristics.
