Abstract:

Dust emission has significant influences on the air quality of Nanjing. Annual emissions of soil, paved road, and construction dusts in 2010 were estimated by using AP-42 methods and their spatial distributions with a 3 km×3 km grid resolution are given. Results showed that the emissions of PM10 in Nanjing were 261, 67 270, and 7 540 tons, respectively. The largest dust emission was from the paved road, and the emission value gradually decreased from downtown to suburban area. Overall, the dust emission of PM10 in Nanjing was less than that in Shanghai and was about 67.3% of the local industry emission.

Key words: emission inventory, soil dust, paved road dust, construction dust, Nanjing
