In this paper, a non-linear mathematical model to study the effect of toxicants on the two or more interacting species systems is proposed and analysed. The cases of constant emission and instantaneous spill of a toxicant are considered in the model study. In competition species by assuming that the growth rate of the species increases as the uptake concentration growth rate of the equilibrium level of the population. It also pointed out the effect of toxicant on the survival species or competition species.
