Assessment of Gaussian distribution Pattern of Pollutants in Lafarge Cement Factory Sagamu, Ogun State, Nigeria

Air pollution consequences have been evident both in rural and urban cities. A major source of air pollution is the cement factory, which releases pollutants such as nitrogen oxide, sulfur oxides particulate matters and many more. The aim of the research is to assess the distribution pattern of the seven (7) under study pollutants from Lafarge cement factory Sagamu, Ogun State. The study looked at the various types of distribution patterns in factories as well as the different types of Gaussian distribution in cement factories which include 3 parameter Log-Logistic, Log-Gamma, 3 Parameter Inverse Gaussian, Lognormal, 3 Parameter Gamma, Beta, Logistic, Uniform, Cauchy, Inverse Gaussian. Data of PM2.5, PM10, CO, CO2, NO2, SO2 and VOC were collected weekly for 37 weeks, along Ikorodu route, Lafarge cement factory Sagamu, Ogun State. Calibrated handheld Aeroqual series 500 was used for the measurement of the pollutants. Gaussian plume model was used in analyzing the data collected. Therefore, the finding showed that, PM2.5 and NO2 both have 3 parameter Log-Logistic distribution pattern, SO2 and CO have Uniform distribution pattern while PM10, CO2 and VOC have distribution patterns of Log-Logistic, Beta and Cauchy respectively.
