The soils contaminant content is influenced mostly in the cities by antrophogenic effects, such as building operations, vehicular traffic, inefficient saverage or drainage problems, when different materials add to the soil. These materials location and movements are changing continuously in soils. The pollution degree depends on the distance fr
...om the surface, the composotion of the soil, the effect rate, the thickness of soil, the composition and proportion of soil-forming minerals. In our study the heavy metal contant in urban soils was examined in district XI. in Budapest, based on different chemical and mineralogical properties of soils.
