谭裕沟隧道CO,SO₂和NO_x排放因子研究

摘要: 通过1997年7月谭裕沟隧道内CO,SO₂和NO_x的连续分析,研究了其污染状况和特征,根据分析结果计算了机动车排放CO,SO₂和NO_x的平均排放因子.结果表明,机动车能排放出较高水平的CO和NO_x,在城市中CO和NO_x有相当大的部分来源于机动车排放,而SO₂的排放量则非常小.

Abstract: Pollution status and characteristics are studied in this work on the basis of results of continuous monitoring of CO,SO₂ and NO_x in Tanyugou highway tunnel during July 17 and July 19,1999.Meanwhile,average emission factors of CO,SO₂ and NO_x are calculated.Results show that vehicles could emit high level of CO and NO_x and contribute a large portion in urban areas comparing with SO₂.
