Assessment of the Spatial Distribution of Carbondioxide Pollution Emitted by Cement Industry Located in Sagamu, Nigeria

Abstract

Cement factory produces air pollutants that contaminate and cause adverse effects on the health of dwellers of the affected environment. These pollutants enter the body and become injurious by initiating or aggravating problems in the respiratory, circulatory and nervous systems. During the production of cement, many processes like crushing, raw milling, calcining, burning and cements milling, release pollutants to the immediate environment. This study aimed at estimating the discharge rate of carbon dioxide (CO2) pollutant emitted from the production/combustion unit of Lafarge Cement Factory Sagamu Ogun State. Six points on each of the three major routes that lead to the factory were used as the sampling points for the study. Gaussian plume model method was applied in developing the model equation. Raw data obtained from the field was used to determine the spread of CO2 concentration. The study showed that there were emissions of CO2 within the study area, with an average monthly highest discharge rate of 773.333 ppm on Ikorodu route, and the lowest discharge rate on Abeokuta route (689.875 ppm). Consequently, the findings can be used to formulate and validate models as well as develop co-correlation among the three routes in the study area.
