Mathematical models for estimation of gas pollutant dispersion

A mathematical model for computation of gas concentration due to its dispersion has been formulated. The equations deduced are suitable for estimation of gas concentration, within the limits of our study as shown by significance of the overall regression and most of the factors studied. The concentration of NO2 is inversely proportion to the height of the sampling station, and proportional to distance from traffic and population activities and from the sea. The level of pollution was inversely proportioned to wind speed. Day pollution concentrations were higher than night levels
