[Establishment and Spatial Distribution of Anthropogenic Ammonia Emission Inventory in Zhejiang Province].

The ammonia emissions inventory of Zhejiang Province was established in 2017 using the activity data of various ammonia emission sources, emission factors, and an estimation method. Ammonia emissions for each source and city in Zhejiang Province were analyzed. The spatial distribution and intensity of ammonia emissions in 2017 were mapped using ArcGIS software.

[Diurnal Variations and Source Apportionment of Water-soluble Ions in PMDuring Winter in Nanjing Jiangbei New Area].

To gain a better understanding of the day-night variation characteristics of water-soluble ions, PM samples were continuously collected for two months in the Nanjing Jiangbei New Area during winter. The diurnal variation and sources of water-soluble ions were studied. Results showed that the mass concentration of water-soluble ions ranged from 17.

[Establishment and Characteristics of an Artificial Ammonia Emissions Inventory in Jiangsu Province from 2013 to 2017].

According to activity level data of various ammonia emission sources in Jiangsu Province, using a reasonable inventory calculation method and emission factor, an ammonia emission inventory in Jiangsu Province from 2013 to 2017 was established, and the trend of anthropogenic ammonia emissions over these years was analyzed. The distribution characteristics of anthropogenic ammonia emissions and emission intensity in Jiangsu Province were analyzed using ArcGIS software. The results showed that the ammonia emissions in Jiangsu Province decreased from 624.
