The purpose of this survey is to investigate the current status of metal pollution of the soil in Ulaanbaatar, the capital city of Mongolia. During the last decade, the city has been rapidly urbanized. The most soil erosion occurs in gher districts of Ulaanbaatar city. It was recently found that the arsenic(As) concentration in the soil was higher than the guideline value and the lead (Pb) content in some samples was higher than normal. The source of As pollution appears to be the coal combustion in three power plants in the city. The sources of the increase in Pb pollution might be the remarkable increase in the number of used vehicles and the increase in the use of leaded fuel in the last few years. Additionally, the concentration of heavy metals in the urban soils of Ulaanbaatar was compared with the mean values of the heavy-metal concentrations in the soils of other countries; the comparison results will shown this study.
