| Abstract: | The main factors of ambient air monitoring in Xuchang City were SO 2,NO X,total suspended particulate (TSP),dustfall and sulfation rate during the 9 th Five Year Plan.The ordering of the main pollutants in the urban air was dustfall quantity,TSP,NO X and SO 2.Its seasonal change law usually was winter>spring>autumn>summer.The annual change in the main pollutants was SO 2,NO X,TSP and dustfall quantity.These pollutants were all decreased with a fluctuation trend during the period of the 9 th Five Year Plan. |
