Ecological theories relevant to estimate hazard of chemical exposure to populational proliferation are reviewed. The Leslie matrix model describes dynamics of age or stage-structured populations under stochastic environments. If toxicants' effects are different between ages or stages of test organisms, and the chemical exposure to environments is time-dependent, the Leslie matrix model is the most straightforward method to simulate population dynamics and extinction. The life-cycle sensitivity analysis evaluates relative importance of age-specific or stage-specific toxicants' effects to population growth. This method may be relevant to know important life stages for chemical pollutants t decrease population growth. If life stages that are not important for population growth are excluded from ecotoxicological experiments, the ecological bioassays may be greatly simplified.
