%X This paper concentrates on the study of the long-time behavior of Leslie system, located in a polluted environment. A new model is obtained by considering the effect of the variance of the population on the internal and environmental toxicant density. Sufficient criteria on weak persistence and extinction of the consumer population are obtained. The threshold between weak persistence and extinction can be established in some cases.
