摘要：

In this paper we have considered a two-species competitive system which is also affected by toxic substances. It has been observed that the ratio of the toxic substances of the two species plays a crucial role in shaping the dynamics of the system. Lastly, by using a suitable Liapunov function we have observed that the toxic substances have some stabilizing effect on the system.
