Studying and comparing the efficiency of different types of trees to mitigate the problem of dust pollution

Abstract

Trees play a very important role in filter out the dust pollution, and other fine particles present in air by absorption or accumulation process. The tree species possessing higher dust escaping capacity has higher chances of survival in the polluted areas. This study indicates that evergreen plants with simple, rough, and fast growing trees are good dust arrestors. The study suggested a systematic way of selecting plant species on the basis of their efficiency in dust control (Callistemon , Casuarina equisetifolia, Ziziphus Lotus, and Eucalyptus Globu) .The objective of the present study is to estimate the amount of deposition of particulate on the leaves surface of various species, and estimate the efficiency of four types of trees and to suggest the most suitable plant species foe plantation in dusty area.The results shown that the highest amount of dust deposited on the leaves of Casuarina equisetifolia (8.336 grams), then Callistemon tree (4.635 grams), while the Ziziphus Lotus tree was (2.291 grams), and the smallest amount of dust deposited on the Eucalyptus Globu tree (1.320 grams).The highest dust deposited on the all types of plants were in June, While the smallest amount of dust deposited in September.
