Megjegyzések:	Rapid industrialization and urbanization during recent decades are having dramatic effects on urban soil properties and lead to large discharges of pollutants, which inevitably affect the health of the soil, ecosystems and human populations. The soil, an important component of the Earth that provides vital functions for human society. There are both direct and indirect effects of the soil on human health. Humans are directly exposed to contaminants in soil through skin contact, inhalation, ingestion and consumption of plants grown in soil, whereas indirect effects include interactions between soil, the soil microbial community, vegetation and the nutritional value of foods and human health. In this study, laboratory column experiments were conducted for over 30 days to investigate the transport of nitrate between soil layers. During the experiment the irrigation schedule of the trial was based on the rainfall distribution of a typical summer month in Hungary. Experiment was set up at three soils (loamy sand and two sandy-loam-loam) with similar organic carbon content (between 0.8 and 1.1%) and pH (7.90 and 7.25) but different texture (78-54% sand and 22-46% of silt+clay, respectively). Soils were then analyzed at different depths and vertical concentration profiles were plotted. Overall, highest concentrations were measured in the upper layers for contaminants in the soil column with higher clay content (C), whereas vertical profiles were more uniform in that with lower clay content (S). The results of laboratory column experiments were used to validate solute transport models built-up in HYDRUS modeling environment. Based on the validated models, different scenarios had been considered with variable initial nitrate concentration to predict the vertical nitrate distribution in the investigated soil profiles.
