The aim of the paper was identification of the impact of transport pollution on soil and vegetation grown in roadside soil. These pollutants are not only exhaust fumes but also dust generated by the friction of tires on road surface, fluids leaking from leaky installations and trash thrown by drivers while driving. The plant living in this environment is exposed to various stresses and damage. The main reason negatively affecting plant growth and even causing their death, is constantly increasing air pollution, especially in downtown areas and along busy roads. As a result of the use of salt for deicing, we risk contamination of the soil, resulting in poor plant growth and reduction in soil acidity. In many of these areas contamination exceeds the standards of plant resistance, being the basic cause of diseases and mass dying. The object of the study was corn and its habitat of cultivation. For the purposes of analyses soil samples were collected in the field located in the village of Kośmidry, and the following determination were carried out: pH, salinity, organic carbon content and levels of heavy metals. In the cornfield of the maize the presence of bio-and abiotic factors was noted affecting the health status of plants and the level of weed growth.
