Today, air pollution is one of the most important problems that threaten human and environmental health. Although there are many components of air pollution, heavy metals are of particular importance. The reason for this is that some of the heavy metals are pure toxic at low concentrations, many heavy metals that are nutrients for living beings are harmful at high costs in bile, live biodegradation process, they are not easily degraded in nature and are used in addition to them. For this reason, it is of great importance to monitor the heavy metal concentrations in the air, especially in risky conditions such as traffic processing, industrial activities and populated areas. In this study, it is grown in Samsun city center and frequently used in landscape studies; Tilia tomentosa, Aesculus hippocastanum, Ligustrum vulgare and Catalpa bignoides species have been tried to determine the changes of Cr concentrations in individuals grown in areas where traffic is heavy, less dense and almost none. Within the scope of the study, leaf, bark and wood samples were collected from the plants, and washing operations were also carried out on the bark and leaves. As a result of the study, Cr concentrations in the species subject to the study changed significantly on the basis of species, organs and traffic density.
