Abstract: In order to verify the feasibility of using environmental magnetic methods in the environment monitor at scenic spots by the road dust, the environmental magnetic properties, spatial variation and environmental implications of road dust samples in Kanas, a 5A scenic spot of Xinjiang, were systematically analyzed. The results showed that road dust samples had high contents of magnetic minerals and that ferromagnetic minerals were predominated the magnetic materials in road dust samples. The samples also contained some amount of anti-ferromagnetic minerals. The magnetic grains were mainly coarse particles of multi-domain or stable single domain. Considering that the study area is far from pollution sources of industry zone and city, the magnetic enhancement of road dust samples in the scenic spot was mainly from magnetic pollutants inputs, such as tourism traffic activities, while the roadside soil and the natural dust from atmosphere were minor inputs. Speaking the spatial distribution of magnetic parameters in road dust samples, trends of spatial variations of χLF, SIRM and SOFT were similar, the high values was found at the transfer center of scenic spot, the middle values appeared in roads to the lake outlet and the low values were distributed in the new village and the main roads to villas around the lake outlet. The traffic volume and intensity of different roads played the main role in the spatial distribution of magnetic properties. Therefore, the environmental magnetic methods can be used in monitoring the environmental quality of roads, delineating potential pollution risks and identifying potential pollutant sources, and can provide references in preventing and controlling traffic pollutions at scenic spots.
