摘　　要：采用美国EPA TO-15的方法,研究了2011年3月份闽南城市区域空气中VOCs的含量及其污染特征。结果表明:1)漳州工业区空气的VOCs浓度为200.5μg/m3,污染较为严重;厦门交通干道VOCs浓度为74.0μg/m3,泉州商住区的VOCs浓度77.1μg/m3,污染较轻。2)漳州工业区采样点TOP5占TVOCs的比例最高,达77.3%;厦门交通干道与泉州商住区两采样点的TOP5占TVOCs的比例相近,分别为64.1%和62.0%。在所有的采样点中出现的TOP5组分比较集中,主要包括甲苯、苯、二氯甲烷、异丙醇、乙酸乙酯、1,1-二氯乙烯、萘等。3)机动车尾气的排放、工业溶剂的挥发和废气排放可能是厦漳泉三地大气VOCs的主要排放源。4)厦漳泉的BTEX主要来源于汽车尾气和汽油挥发;其中厦门和泉州BTEX浓度相比较处在较低污染水平,漳州处在中等水平。In March 2011,the air samples were obtained and their content and pollution characteristics of VOCs in the air of the cities in Southern Fujian were studied by US EPA method TO-15. The results showed that:( 1) in Zhangzhou industrial zone,the concentration of VOCs was 200. 5 μg/m3 and was the highest in the air samples; while 74. 0 μg/m3 and 77. 1 μg/m3 in the air samples of the traffic arteries in Xiamen and the commercial and residential areas in Quanzhou respectively.( 2) TOP5 was the most abundant in Zhangzhou industrial zone and constituted77. 3% of the detected TVOCs. The same situation was found in both the traffic arteries in Xiamen and Quanzhou,with 64. 1% and 62. 0% respectively. The detected TOP5 in all these areas contained a few kinds included Benzene,methylene chloride,isopropyl alcohol,ethylacetate,1,1-dichloroethylene and naphthalene.( 3) Vehicle exhaust,volatilization of industrial solvents and industrial exhaust may be the major sources of VOCs in the air of the three locations.( 4) BTEX analysis showed that benzene series compounds were mainly from vehicle exhaust and gasoline evaporation. The concentrations of BETX in Xiamen and Quanzhou were low and within the pollution range,while that of Zhangzhou was within middle pollution range.
