A mathematical statistical method for identification of unknown polluters of rivers

摘要

The paper presents a mathematical statistical method for assisting the identification of unknown polluters of rivers in the case of fish-damage. It is supposed that fish-damage is caused by the waste water of industrial plants and that we know the set of plants to be taken into consideration in this respect. Using the suggested method for every plant belonging to the above set, we are able to estimate the probability that a given plant is responsible for caused fish-damage. The method can be used not only in the case when we know the cause of fish-damage and the chemical characteristics of the waste water, but also in the case of uncertain information about these.
