【摘要】 本文首先分析了2016年太原市城区环境空气PM₁₀浓度状况;其次根据太原市颗粒物源解析结果分析了开放源对太原市城区环境空气中PM₁₀的影响,并采用箱模型测算了太原市开放源PM₁₀起尘量;然后以环境统计数据为基础估算了人为源PM₁₀排放量;最后综合开放源起尘量和人为源排放量估算了太原市大气颗粒物PM₁₀的排放总量。结果表明:2016年太原市大气颗粒物PM₁₀排放总量约为6.44万t。其中,开放源PM₁₀起尘量约为3.37万t;人为源颗粒物PM₁₀排放量约为3.07万t。更多还原

【Abstract】 In this paper,the concentration of PM₁₀ in the ambient air of Taiyuan city in 2016 was analyzed,and the effect of open source on PM₁₀ in the ambient air of Taiyuan city was analyzed according to the results of particle source analysis in Taiyuan. The dusting amount of open source PM₁₀ in Taiyuan was calculated by using box model,and then the anthropogenic PM₁₀ emissions by sources were estimated on the basis of environmental statistics. Finally,the total PM₁₀ emission of atmospheric particulate matter in Taiyuan City was estimated by combining the amount of open source dust and anthropogenic source emissions. The results showed that in 2016,the total amount of PM₁₀ emission of atmospheric particulate matter in Taiyuan City was about 64400 tons,among which,the total amount of PM₁₀ emission from open source PM was about 64400 tons. The PM₁₀ emission of particulate matter from anthropogenic sources was about 30700 t,and that of 10 dusts was about 33700 t.更多还原
