The olfactory system of crustaceans as a model for ecologo-toxicological studies

Based on our own studies and on literature data, there are considered peculiarities of structural-functional organization of the crustacean olfactory system and effects of pollutants on it. The behavioral reaction changes based on chemoreception in the polluted aquatic environment are described. Usefulness of study of the crustacean olfactory system is substantiated as a perspective object of ecologo-toxicological investigations.
