SOURCE IDENTIFICATION OF INHALABLE PARTICLES OF FOG AND HAZE IN SHIJIAZHUANG
In recently years, it draws peoples attention to the high frequency of fog and haze. Shijiazhuang is a city where fog and haze high frequency. With the inhalable particles of fog and haze of the town of Shijiazhuang as the main research target, according to the data of the chemical element analyzed?adopted two kinds of method of elemental composition in source identification of Enrichment factors(EF) and factor analysis(FA), four main sources of inhalable particle are identified. The EF results showed that in Shiazhuang, the elements EF>10 is mostly Zn, Pb, and EF of Pb is be close to 500, and Enrichment valus of Al, K, Cr, Mn, Zn, Pb of the inhalable particles of fog and haze is more than of the inhalable particles of normal days, especially K、Zn and Pb is more markedness. The PM10 FA results indicated that K element and Al element of the inhalable particles of fog and haze is more than of the inhalable particles of normal days, and winter is more than other seasons, and the main sources and contribution rates in fog-haze were respectively: coal and refuse combustion source 33.65 %, soil source and cement/limestone source 33.18%, traffic source 17.486%, and steel source 11.02%. The main sources of inhalable particles of fog-haze in Shijiazhuang are the coal and refuse combustion dust and soil and cement/limestone construction dust.
