The level of pollution has reached the dimensions that threaten human health, with the rapid urbanization and the increase of energy consumption especially in developing countries. Every year in the world, millions of people lose their lives because of air pollution. Heavy metals have a separate precaution in pollutants, especially in terms of human health, because they can remain intact in nature for long periods of time, they tend to bioaccumulate and some are toxic or carcinogenic even at low concentrations. Therefore, monitoring of heavy metal pollution and determination of risky areas is very important. Biomonitors are the most commonly used methods for monitoring heavy metal pollution. However, determining which organelles are more suitable for monitoring the metal is essential in order to ensure that the monitoring is reliable. In this study, it was aimed to determine the variations of the concentration of Ba, Na, Al, B, Ca, Fe, K, Mg and Mn elements depending on the traffic density in leaves, seeds and branches of Tilia tomentosa which are grown in areas with heavy, low dense and non traffic areas. As a result of the study, it was determined that the heavy metal concentrations in leaves and seeds except Fe were increased due to traffic density. This situation can cause serious problems for human health, especially since the leaves and seeds of linden individuals grown in traffic-intensive areas are consumed as tea.
This study aimed that the increasing population and the number of vehicles in the cities have brought air pollution. It has become one of the most important problems of the modern age. Many pollutants emerge from city roads due to exhaust gases, car wheels, vehicles and vehicle wear, and these sources of pollution are affecting the development and health of living things in their environment. Among these pollution factors, heavy metals have a huge important role of air pollution. The heavy metals tend to bioaccumulate and some have toxic effects even at very low concentrations. Therefore, monitoring of the change in heavy metal concentration is extremely important. Plants are used as a biomonitor for determining heavy metal pollution. In this study, it was tried to determine the possibilities of using Prunus cerasifera as biomonitor which is frequently used in landscape studies. So concentrations of Ba, Al, Ca, Fe, K and Mg elements were determined by analyzing Prunus cerasifera leaves, seeds and branches collected from some areas including no traffic, mid-intensity, intense traffic. As a result of the study, it was determined that the elements other than K were significantly changed at confidence level of least 95% on the basis of organelles. When the changes of the elements on the basis of organelle depending on traffic density were examined, it was found that the concentrations of Ca in leaf, Ba and K in seed, Ba, Fe and Mg in branch increased depending on traffic density.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
