Sand-Dust Aerosol´s Impact on Urban Environment in Xinjiang

Xinjiang is the emission region of sand-dust aerosol as well as the region suffering the severest damage from sand-dust aerosol, whose urban environment especially suffers greater impact from the particles of sand-dust aerosol. The impact on urban environment in Xinjiang is mainly attributed to the sand-dust weather in the multiple sand-dust seasons. The variation trend is in conformity with that of the sand-dust weather. Upon the occurrence of the sand-dust weather, PM10 of the city increases sharply. The sand-dust aerosol turns into the most important pollutant. In the multiple sand-dust seasons, the sand-dust aerosol is the primary pollutant. In the non-heating season, the content percentage of the sand-dust aerosol in the pollutants of Crumbs reaches up to 37% and PM10 during the sand-dust weather period changes obviously, indicating the sand-dust weather has great impact on the atmosphere quality of Xinjiang.
