MODERN ECOTOXICOLOGY AND ITS MAIN MISTAKE S.A.Ostroumov Moscow State University, Moscow, Russia The aim of this short communication is to identify the main mistake of modern aquatic ecotoxicology, the main mistake in modern approach to aquatic pollution. The modern science of today will become the obsolete science of tomorrow. What the contemporary scientists consider modern concepts will become what the scientists of the future days will consider obsolete, out-of-date, pseudoscientific or antiquated, primitive and naïve interpretations of facts. This general truth is applicable to the modern concepts of how to deal with aquatic pollution. The modern concept is focused primarily on trying to find out which concentrations of pollutants are ‘toxic’, and which are not toxic. On the basis of this knowledge, the main effort is to limit the input of pollutants to surface aquatic ecosystems, with the aim to have the concentrations of the pollutants at the levels which are not ‘toxic’. The most convincing criterion of toxicity of the pollutant is death or pathology of organisms. This is the basic concept or paradigm of the modern science. This is the modern and naïve interpretation of facts of aquatic ecotoxicology, environmental science and ecology. What is a more advanced approach? It is formulated and explained in the following publications and online materials. Not only the input of pollutants is important. Equally important is another factor which is underestimated in modern ecotoxicology. This other – underestimated - factor is the hazard of a decrease in efficiency of the ecological machinery of the aquatic ecosystem, namely the ecological machinery of water self-purification. This decrease can be induced by relatively low - innocent in appearance – concentrations of relatively mild pollutants. This decrease is not associated with mortality or morphological pathology of organisms. That is why these relatively low concentrations, and the relatively mild, almost ‘innocent’ pollutants escape the attention of modern scientists and experts. Example which illustrates the argument formulated above: relatively low, ‘non-toxic’, and definitely non-lethal concentrations of synthetic surfactants (components of detergents and shampoos) induced a decrease in water-filtration by marine bivalve mollusks [1 ], freshwater bivalve mollusks [ 2 ], crustaceans exemplified by daphnia [ 3 ], and by rotifers [ 4 ].
