    Abstract: Cement dust retention capacity of leaves of different trees and plants has been investigated. The results indicate that Neem leaves have the highest capacity. The dust retention capacity of each type of leaf was calculated as- Dust retention capacity = W x 10 3 / A, where A is area of leaf in cm 2 and W is weight of dust retained in gm. For several decades, air pollution from cement
