ENDANGERED WATER QUALITY: NEW HAZARDS. DISCOVERY OF HIDDEN HAZARDS AND PARADOX OF LOW CONCENTRATIONS OF CHEMICALS. New data show: low levels of pollutants in water can be as bad as very high toxic concentrations. Environmental hazards: small amounts of the aquatic pollutants that were studied do not kill organisms of ecosystems, however, they do not make the ecosystem stronger. They do just the opposite: the low non-lethal concentrations of the chemicals in water bring about very bad effects on functioning (vitality) of the entire ecosystem. Namely, the activity of ecosystem in water self-purification goes down. As a result, water quality goes down

New data show: low levels of pollutants in water can be as bad as very high toxic concentrations. Environmental hazards: small amounts of the aquatic pollutants that were studied do not kill organisms of ecosystems, however, they do not make the ecosystem stronger. They do just the opposite: the low non-lethal concentrations of the chemicals in water bring about very bad effects on functioning (vitality) of the entire ecosystem. Namely, the activity of ecosystem in water self-purification goes down. As a result, water quality goes down dramatically. This was discovered in the series of scientific articles. Authors, co-authors: Moscow University, scientific institutions of U.K. (Plymouth), Germany (Berlin):
