Evaluation of the Downwind Dispersion of Particulate Matter from Cement Manufacturing Facilities in Athi River, Machakos County, Kenya

Abstract

In this study, the transportation and dispersion of particulate matter (TSP, PM 10 and PM 2.5) from two cement milling and grinding facilities (Cement Factory 1, CF1 and Cement Factory 2, CF2) was determined using AERMOD software. Isokinetic sampling based on Environmental Protection Agency (EPA) standard methods 1 through 5 was used to determine the emission rates from the stationary emission sources. The results showed that the peak maximum concentration of particulate matter (TSP, PM 10 and PM 2.5) was below the permissible limits under the EMCA, 2014 and WHO Air Quality Guidelines, 2021.
