交通来源颗粒物及其无机成分污染特征的研究

Study on Characteristics of Particulate Matters and Their Inorganic Compositions from Traffic Sources

摘要: 对谭裕沟隧道和梧桐山隧道TSP,PM₁₀和PM_2.5质量浓度和主要无机成分的分析结果表明,交通来源颗粒物中细粒子主要来源于机车尾气排放,粒径较大的颗粒物则主要来源于机动车行驶载带的地面扬尘.

Abstract: Analytical results of TSP,PM₁₀ and PM_2.5 mass concentrations and their major inorganic compositions obtained in Tanyugou highway tunnel and Wutongshan highway tunnel showed that the fine particulate matters mainly came from vehicle emission and the coarse particles were from the road dust raised up by the vehicles movement.
