Abstract:
Based on the data of mean air pollutant concentrations(TSP, PM10,SO_2,NO_2) and meteorological factors(visibility,wind speed,temperature,humidity,precipitation,total cloud cover and lower cloud cover) in 2002 over the urban areas of the central Liaoning Province,an analysis was made of the status and extent of pollution in theses areas and the correlation of pollutants and various meteorological factors.The results show: the predominant air pollutants are TSP and SO_2;air pollution is the most serious in winter,the most slight in summer.The air pollution is the most serious in Benxi,the second in Anshan,the third in Shenyang,then in Fushun,and the least in Liaoyang.The correlation of pollutants with visibility and temperature is very good,and the correlation of pollutants with various meteorological factors is better in plain cities than that in mountainous cities.
