ВИЗНАЧЕННЯ ЕКОЛОГІЧНИХ НОРМАТИВІВ ДЛЯ БАСЕЙНУ РІЧКИ УДИ В МЕЖАХ ХАРКІВСЬКОЇ ОБЛАСТІ

Abstract

The article improves the method of establishing ecological norms of surface water quality in accordance with Ukrainian legislation and the Water Framework Directive of the European Union, which represents the scientific novelty of work. For the first time environmental norms for water flows of the Udy river basin have been determined on the basis of the forecast of their qualitative condition, taking into account the landscape-geographic features of the functioning of aquatic ecosystems. Ranking of the observation posts for the quality status of the Udy River in terms of the ecological index value for the permissible and target ecological standard makes it possible to identify the most polluted watercourses. The improvement of the methodology for establishing ecological norms of surface water quality has a purpose to introduce an iterative approach to the management of surface water quality into the water protection practice of Ukraine and its adaptation to the environmental legislation of the EU countries.
