武汉市大气中TSP、SO_2、NO_x、CO的变化规律研究

The Study on the Variation of TSP、SO_2、NO_x and CO in Wuhan Urban Atmosphere

对武汉市大气中 TSP、SO2 、NOx、CO浓度的日、月、年变化规律以及 TSP、NOx 浓度和车流量之间的关系进行了研究。结果表明 :SO2 浓度与温度之间呈显著性负相关关系 ,NOx 浓度和车流量之间呈显著性正相关关系 ,TSP与 NOx、CO浓度的变化趋势一致 ,机动车尾气烟尘及行驶引起的扬尘 ,将是

In this paper,the day,month,year variation of TSP?SO 2?NO x ?CO concentration and flowing were studied in Wuhan urban atmosphere.It indicated that SO 2 conentration and temperature had notable positive interrelated relationship,NO x concentration and flowing had notable negative interrelated relationship.The variation tendency of TSP was the same with that of NO x ?CO concentration.The dust that cause by driving motor vehicle exhaust would be the main source of TSP.
