Mathematical analysis for the quantification of susceptible (S(t)), Infectives (I(t)) and Removal (R(t)) populations in
SIR model due to industrial pollution has been studied in the paper. The study concerns the analysis of SIR model to quantify
the varying populations of S(t), I(t) and R(t) with three different sizes in the populations. A system of non- linear ordinary
differential equations are solved using Runge - Kutta fourth order method to investigate the long term effect of industrial
pollution on the human population in terms of spread of diseases.
