空气中有害物质冬季污染情况的调查和分析

监测了2007年1月27号到2007年2月2号惠州市冬季主要交通干道空气污染情况，并采用气相色谱分析，结果显示在监测期间苯的含量为2μg／m^3-35μg／m^3，甲苯的含量为3μg／m^3-26μg／m^3,二甲苯的含量为0μg／m^3-95μg／m^3，乙酸正丁酯的含量为1μg／m^3-29μg／m^3，乙苯的含量为0μg／m^3-17μg／m^3，苯乙烯的含量为0μg／m^3-12μg／m^3，正十一烷的含量为0μg／m^3-22μg／m^3,CO的含量的为1．4ppm-4．1ppm，CO2的浓度为0．030％-0．060％，通过和国内其他城市的调查情况相比，其污染的程度较低，且监测结果表明，污染的情况受风速的影响较大，同时，还提出了改善城市污染状况的一些建议。

Investigation and Analysis of the Injure Pollution in Ambient Air in Winter

In this paper, injure pollution in ambient air at traffic road of Huizhou from Jan.27 to Feb.2, 2007 was examined. The results indicated that the concentrations of benzene, toluene, xylene n-butyl acetate, ethyl benzene, cinnamence styrene, andeane were in the ranges of 2-35μg/m^3, 3-26μg/m3, 0-95μg/m^3, 1-29μg/m^3, 0- 17μg/m^3, 0-12μg/m^3, 0-22μg/m^3, respectively. CO wasl.4-4.1ppm and CO2 was 0.03-0.06 %. It was less pollution than other cities in China. It was also found that injure concentrations had a great relationship with the wind speed. Some suggestions to improve the air quality were put forward.
