Abstract: In this paper a mathematical model is proposed to study the effect of environmental pollution on a predator-prey system. The conditions for the local and global stability of the equilibria are obtained. The possibility of occurrence of periodic solutions is analysed and further existence of Hopf Bifurcation with respect to the appropriate parameter is examined. The conditions for uniform persistence of the model are obtained. The results of persistence and Hopf Bifurcation with respect to the appropriate parameter are verified through numerical simulations.
