谭裕沟隧道CO,SO_2和NO_x排放因子研究

Study on Emission Factors of CO,SO_2 and NO_x in Tanyugou Highway Tunnel

通过 1997年 7月谭裕沟隧道内CO ,SO2 和NOx 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NOx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NOx,在城市中CO和NOx 有相当大的部分来源于机动车排放 ,而SO2

Pollution status and characteristics are studied in this work on the basis of results of continuous monitoring of CO,SO\-2 and NO x in Tanyugou highway tunnel during July 17 and July 19,1999.Meanwhile,average emission factors of CO,SO\-2 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 SO\-2.
