空气中有害物质冬季污染情况的调查和分析

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

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/m3～35μg/m3,甲苯的含量为3μg/m3～26μg/m3,二甲苯的含量为0μg/m3～95μg/m3,乙酸正丁酯的含量为1μg/m3～29μg/m3,乙苯的含量为0μg/m3～17μg/m3,苯乙烯的含量为0μg/m3～12μg/m3,正十一烷的含量为0μg/m3～22μg/m3,CO的含量的为1.4 ppm～4.1 ppm,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。

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.
