Increasing population and industrialization have caused air pollution and air pollution in some cities has increased to such an extent that it has started to threaten human health and has become one of the most important agenda topics of our day. Many pollutants arise in cities due to exhaust gases, car wheels, vehicles and vehicle wear. Heavy metals are one of the most infamous pollutants, because they can remain in nature for a long time without degradation and the amount of heavy metal concentration in the environment is constantly increasing. Heavy metals also tend to bioaccumulate. Therefore, the determination of heavy metal concentration is of great importance in terms of identifying risk regions and risk levels. Determination of heavy metal concentrations in plants is important both for determining plants’ ability to remove heavy metals from the air and thus to improve air quality, as well as for monitoring air quality. Bio-indicators are the most important indicators of the change in the concentration of heavy metal in the atmosphere. This study aims to determine the usability potential of Scotch Pine (Pinus sylvestris) in monitoring the traffic related heavy metal concentration. For this purpose, samples of Scotch Pine individuals were collected from one of the busiest highways of Turkey, at the route of Ankara-Istanbul, from refuges, at roadsides and at distances of 3 m, 10 m, 30 m, 50 m and 100 m from the roadside, some of the branch and needle samples were washed and the change of Cu, Pb and Cd concentrations on these samples was determined. As a result of the study, the change of the concentrations of these heavy metals depending on distance to the road, organelle and washing conditions all seem to indicate that the Scotch Pine is a good bio-monitor which could be used especially to monitor the change of Cd concentration.

Heavy metals are one of the most infamous air pollutants. They do not deteriorate easily in nature and they tend to bioaccumulate in nature. Because of their significance in terms of potential damage to human and environmental wellbeing, the monitoring of heavy metal pollution and identifying risk-prone regions is of great importance. Bioindicators are the most important determinants of the change in the concentration of heavy metals in the atmosphere. While plants play the biggest and most important role in reducing pollution in all of its types, they are also the ideal bioindicators. However, some plant species are better equipped to detect heavy metal accumulation than others. This study aims to determine the usability potential of Scotch pine (Pinus sylvestris) in monitoring traffic-based heavy metal concentrations. For this purpose, samples of Scotch pine individuals were collected from one of the busiest highways in Turkey (along the Ankara-Istanbul route) from refuges at roadsides and at distances of 3m, 10m, 30m, 50m, and 100m from the roadside. Some of the branches and needles of the samples were also subjected to washing processes and the changes of Ni, Cr and Zn concentrations were determined for these samples. The change of Ni, Cr and Zn concentrations depending on the distance to the road, washing conditions and organelle were evaluated separately. We determined that Scotch pine is a good biomonitor – especially for monitoring changes in Cr concentrations.
