A stochastic model for the risk of biota exposure in case of accidental environmental pollution

We describe a stochastic model for the risk of biota exposure in case of accidental environmental pollution. The model is based on the formalization of the notions of accident, environmental pollution, biomass, biota sensitivity, and their consecutive dependence on each other in case of an accident. The result of the article is the determination of a risk function which includes all elements of the considered model and quantitatively assesses the reduction of the biota in case of an accident.
