MONITORING OF TRAFFIC AIR POLLUTION USING MAGNETIC PROPERTIES OF TREE LEAVES IN ISFAHAN, IRAN

Isothermal remanent magnetization (IRM3oomT) of three types of tree leaves namely Ulmus carpinifolia, Platanus orientalis and Ligustrum ovalifolium determined and IRM3oomT normalized for the leaf area. The normalize 2-D magnetization of leaves as shown by results controlled by leaf morphology, and traffic density. Platanus orientalis leaf has highest 2-D magnetization and Ligustrum ovalifolium leaf having least 2-D magnetization suggesting greater ability of Platanus orientalis tree leaves to reduce magnetic particulate. Therefore, a magnetic survey of tree leaves recommended as an inexpensive and rapid tool for monitoring of air pollution in urban areas.
