黄冈市城区空气污染的变化趋势及其防治对策研究

The tendency and countermeasures of air pollution in Huanggang city proper

对黄冈市城区近5年来造成空气污染的三个主要因子SO2、NO2和TSP的连续监测结果进行了系统分析,发现SO2年日平均浓度值的变化呈下降趋势,而NO2和TSP年日平均浓度值的变化呈上升趋势,该地区的空气污染已从煤烟型污染向媒烟——汽车尾气混合型污染转变.从继续控制煤烟型污染,加强控制汽车尾气污染、扬尘污染和工业污染等四个方面提出了防治对策.

The paper analyses systematically continuous monitoring results of 3 major pollution factors SO2, NO2 and TSP in current 5 years in Huanggang city proper. It is found that yearly daily average concentration value of SO2 comes down year by year, but yearly daily average concentration value of NO2 goes up year by year. The air pollution of the area has being changed from coal combustion type into the mixed type with coal combustion and waste gas emission of motor vehicles. The controlling countermeasures are suggested as the following; controlling pollution of coal combustion continuously, strictly controlling waste gas emission of motor vehicles, floating dust and industrial pollution.
