Study of cement dust retentivity of various plant
Author(s): Dr. Prakash Dubey, Jyoti Bhadauriya
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 103 / A, where A is area of leaf in cm2 and W is weight of dust retained in gm. For several decades, air pollution from cement industry has remained one of the most serious man made problems. Over 105 cement factories produce 500 lakh tones per annum and cause dust pollution in and around the factory area. In general, dust pollution by cement industry causes a variety of leaf injury ranging from excess water loss and impairment of photosynthesis by blocking the stomatal aperture. A study was conducted on cement dust retention capability of different species in and around a cement factory.
