Effects of Air Pollution on Some Chemical Compounds of Cherry Laurel (Prunus Laurocerasus L.) in Kastamonu
Abstract
Industrialization and overuse of automobiles result in the release of
toxic matter in the air which may induce harmful effect on the living system
such as plant, animal, soil fauna. All pollutants from traffic and factories
suppress plant growth and development by preventing physiological and
biochemical reactions. However, trees can play an important role in improvement
the air quality by prevention of environmental pollution in the urban environment.
The present study was conducted in Kastamonu city. It purpose was to point out
the impacts of air pollution caused traffic on chemical compositions in Prunus
laurocerasus L. For this purpose, we collected leaf sample of trees from areas
away from the traffic for control, while polluted sample were selected from
regions where the traffic was heavy (Salıpazarı) and less dense (Kısla park) in
Kastamonu city center. In each of leaf sample, the amount of chlorophyll
pigments, carotenoid, total soluble protein, MDA-malondialdehyde, H2O2,
enzymatic antioxidants such as APX, CAT, GPOX and SOD activities, and
non-enzymatic antioxidants measurements were performed. According to data, the
amount of chlorophyll b and total chlorophyll, and CAT and GPOX activities was
determined higher in non-polluted plant but chlorophyll a, proline, total
soluble carbohydrate and SOD activity enhanced excessively contaminated leaf.
APX activity was the highest in lighter contaminated leaf samples but H2O2 was
the lowest. As a result, it could be concluded that the growth and development
of cherry laurel was found to be affected traffic pollution depended on the
severity of pollution. And also, on the basis of this study it can be said that
cherry laurel is resistant to air pollution, and the results could be used in
the future research to understand the role of individual tree species in air pollution.
