| Abstract: | The results are obtained by detecting benzopyrene concentration in PM_(10)samples in national ambient air monitoring sites of Nanjing.The monthly average concentration curve of benzopyrene shows double peaks shape,winterly autumnal vernal estival.Effected by local industrial emission,the level of benzopyrene concentration in ambient air of northern area of Nanjing is higher than that of southern area and the level of benzopyrene concentration in Nanjing is lower than that of other cities of China. |
