大庆地区总悬浮微粒乙醇溶物和水溶物污染状况分析

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。

Analyses of the pollution conditions of ethanol/water solvent total suspended particle in the air of Daqing region

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.
