柴油机发电厂对大气环境影响的调查与分析

An Investigation of Air Pollution by Diesel Engine Power Station

通过对柴油机发电厂周围大气环境中污染物ＳＯ_２、ＮＯ_ｘ、ＴＳＰ、Ｂ（ａ）Ｐ、Ｐｂ的调查，表明受电厂排污影响，使调查区域出现一个高浓度大气污染带，污染物的时空变化有一定规律。因子分析结果表明主要污染物因子以ＳＯ_２和Ｂ（ａ）Ｐ为代表，尤以Ｂ（ａ）Ｐ污染为突出，应在区域污染防治中加以重视。

An investigation of air pollutants(SO_2,NOx,B(a)P& Pb)in the environment around one diesel engine power station indicates it is a high concentration belt of pollutants in the investigation area where the air environment have come to serious pollution,and the variations of pollutants have some regular pattern in time and space. The main pol lutants provedby the method of factor analysis are SO2 and B(a)P. B(a)P is obviously polluting and should be recog nized in the regional prevention and treatment of environ mental pollution.
