| Abstract: | In this paper we apply the theory of biomathematics to study the effects of toxicants on population in polluted enviroments.We put forward a mare rational mathematical model which is in keeping with the ecological demands and establish some mathematical criteria of the persistence and extinction of population.These criteria have extensive practical meaning of ecology. |
