Abstract

Abstract

In order to explore the magnetic response of environmental pollution about dust-loaded leaves on main road in Baoji city, different types of leaves on both sides of streets were collected for systematic environmental magnetic tests. The results showed that the concentration of magnetic minerals on street leaves were higher than that in the campus and the main magnetic minerals were multi-domain magnetite and maghemite. The diameter of magnetic mineral was concentrated in 0.1~5 μm, among which the herbaceous far from the traffic lines had a relatively fineer particle size of 0.1~1 μm. Environmental pollution recorded by vegetation leaves at the same height and at different times (May and November) was different. Pollution recorded by herbaceous at 0.05 m height and trees leaves at 4 m height was more serious in May than in November, while that of the leaves of shrubs at 0.25 m and 1 m was worse in November. The spatial distribution of urban main roads presented two pollution peak areas, the zone A including Jiangtan road and Baofu road, and the zone B where Dongfeng road was located in, which are related to heavy traffic and heavy industrial enterprises.
