摘　　要：通过对大庆地区总悬浮微粒（TSP）中主要化学组成─—乙醇溶物和水溶物的测定分析得知，乙醇溶物占TSP的年均值为12．25％，高于北京市（6．41％），在空气中的平均浓度为0．0148mg／m3。乙醇溶物中有机物平均占58.6％，多为含羟基的有机物；无机物主要是控的硫酸盐和硝酸盐。水溶物占TSP的平均值为27.93％，高于北京市（11．29％），在空气中的平均浓度为0．0324mg／m3。从TSP中乙醇溶物和水溶物的测定结果可以看出各测点采暖期乙醇溶物、水溶物的浓度显著高于非采暖期，但其致突变强度比北京市弱。It is derived from the measurement analyses of the main chemicalcompositions of Total Suspended Particle (TSP) in the air of Daqing region, i. e.ethanol/water solvent pariticle,that the annual average value ratio of ethanol solvent toTSP is 12.25% (higher than the ratio of 6. 41 % in Beijing ) and the average concentra-tion value in the air is 0.0148mg/m3. The average percentage of organics, mostly hy-droxide,to ethanol solvent is 58. 6%. The inorganics are mainly ammonium sulfate andammonium nitrate. The annual average TSP of water solvent is 27. 93 % (higher than theratio of 11. 92 % in Beijing)and the average concentration value in the air is 0.0324 mg/m3. The measurement results of ethanol/water solvents in TSP show that the concentra-tion values of ethanol/water solvent collected from various measuring spots during heat-ing season are obviously higher that durinR non-heating season,however the changingintensities of concentration values are weaker than those in Beijing.
