Abstract
The response range of Ceriodaphnia affinis and Daphnia magna from the collection of cultures of the laboratory of ecological and toxicological research of V. N. Karazin Kharkiv National University to the reference chemical substance K2Cr2O7 was determined experimentally under the conditions of using the OECD methodology “Daphnia sp. Acute immobilization test, OECD Guideline for the testing of chemicals”. The obtained results of the experiment became the basis for the inclusion of this method in the set of methods for establishing the standards - the ecological standards of water quality in Ukraine, in particular the water quality standards for the protection of the aquatic ecosystem from dangerous short-term effects of chemicals. Such a proposal is put forward on the basis of an analysis of modern surface water quality regulation systems in the EU, Canada and the USA. The implementation of such an approach will make it possible to make management decisions in the short term to eliminate the critical consequences of exposure to dangerous chemicals during military operations on the territory of Ukraine.
