The goal of the paper is improving the system of criteria for environmental hazards of chemicals that pollute environment. A conceptually new system of criteria (principles) for identification of environmental hazards is proposed by the author. The system includes four blocks according to the four levels of anthropogenous disturbances in living systems. As an example of a non-lethal but potentially important effect produced by a man-made chemical, some author’s new data on the inhibitory effects of a membranotropic xenobiotic (a synthetic surfactant) on bivalve molluscs are presented. A non-ionic surfactant inhibited the water filtration by bivalve molluscs.
