英文摘要	Magnetic properties of atmospheric dusts collected during the period of Beijing Olympic Games in Chaoyang, and some topsoil samples were measured in order to disclose the source of air pollutants. Thermomagnetic, isothermal remanent magnetization and hysteresis measurements reveal that the dominant magnetic minerals are magnetite. Compared with topsoil samples, the concentration of magnetic particles in atmospheric dust samples are higher, and the magnetic grains are coarser. These results suggest that the magnetic particles in atmospheric dust samples come from anthropogenic rather than natural sources. Correlations between magnetic susceptibility and temporal variations of concentration of air pollutants indicate that magnetic particles mainly originated from industrial and traffic emissions in summer, whilst the coal burning for heating is a prominent contribution to the high magnetic mineral concentrations in winter. The temporal variations of magnetic parameters imply that the traffic control regulations in Beijing were essentially remarkable during the period of Olympic Games. These results suggest that magnetic measurement can serve as an efficient complementary tool for monitoring environmental pollution.
