In this paper, the authors considered a single-species model with stage-structure in a polluted ecological environment. Subject to the outside toxin input quantity being stable, the authors established the sufficient conditions under which the species will be permanent using Lyapunov method. At the same time biological implications briefly of these results are discussed.
