%X The ammonia emission survey in Beijing showed that the contribution of NH 3 emission from fertilizers,animal waste,human,industrial facilities,and wastewater treatments is 41%,34%,22%,2%,and 1% respectively.The analysis of the effects of atmospheric ammonia on the formation of secondary particles in Beijing indicated that NH3 concentrations in atmosphere is the key factor in the formation of secondary particles in spring,autumn,and winter in Beijing.
