Analysis, Evaluation and Stochastic Modeling of Emission Levels of Three Greenhouse Gases (CO 2 , H 2 O and SO 2 ) through Vehicular Activities within Enugu Metropolis

Research was conducted to determine the level of emission of three greenhouse gases (CO 2 , H 2 O and SO 2 ) through vehicular activities within Enugu Metropolis using gaseous pollutant sampler envirotech ARM 433 and fourier transform infra-red spectroscopy. The analysis showed that CO 2 emission was above the permissible limits of 350mg/m 3 in nine out of the 12 calendar month of the study year, 2015. SO 2 and H 2 O were within their respective emission permissible limits across the length of the year studied. Stochastic model equations showed that relative humidity and traffic density greatly influenced the levels of emission of pollutant/greenhouse gases through vehicular activities in any given environment. Stochastic modeling equation successfully predicted the level of gaseous emissions in 2017 within Enugu metropolis which could be adopted by relevant government agencies towards pollution control measures.
