الملخص الإنجليزي

This thesis treats the qualitative behaviour of the dynamics for some toxicology models.

Two types of models are proposed, one deal with a single species, and another deal with two species in competition, and both are analyzed analytically as well as numerically in different cases.

In the first model, the proposed system consists of three nonlinear differential equations.

While the proposed system, in the second model, consists of five nonlinear differential equations.

The existence and uniqueness of the solution of these two proposed systems are investigated.

The existence conditions for all possible equilibrium points are established.

The local and global dynamical behaviours are studied. Numerical simulation for both the systems is also included.

Finally, the effect of toxicants on the living species in the polluted environment is discussed
