| 摘 要： | 从1997年9月～1998年7月对长春市空气中气相有机烃污染物进行布点监测.实测结果表明，气相有机烃类污染值冬季最高，春季最低．交通路口非甲烷总烃（NMHC）值目变化呈双峰规律，工业区NMHC值日变化呈单峰．随着采样高度的增加，NMHC值逐渐减小．

| Abstract: | Organic vapor pollutants were monitored in the atmosphere of Changchun city from September, 1997 to July, 1998. The results show that the concentrat1on values of vapor hydrocarbons were higher in w1nter and lower in spring. The concentration values of non-methane hydrocarbons (NMHC) showed an obv1ous bimodal type of charge,i. e., the one concentration peak occured once at 8: 00~ 10: 00 and the other at 15: 00~ 17: 00 in traffic road. The diurnal variation of NMHC concentration in the 1ndustrla1 area displayed a single peak at about 1o: oO. The concentration values of NMHC decreased obviously with the increased altitude of collecting samples. |
