摘要:

运用美国环保署AP-42方法及观测资料,估算2010年南京市土壤扬尘、铺装道路扬尘和城区施工扬尘的排放,并给出3 km×3km分辨率的空间分布.研究结果表明,3类扬尘PM10排放分别为0.0261、6.727、0.754万t.铺装道路扬尘的贡献最大,从市区向南北城郊方向,排放逐渐减少.比较而言,南京市3类扬尘PM10的排放总量小于上海,约相当于本市工业排放的67.3%.

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
