MONITORING OF ECOLOGICAL SAFETY OF WATERCOURSES BY MEANS OF OXYGEN INDICATORS

All source information for the tasks of effective management water resources is based on results observations and measurements, ie monitoring. Despite apparent advantages assessing surface quality using comprehensive indicators, creation about 30 most well-known indicators since first attempts in this field hydrochemistry to date, only indicator that combines assessment natural masses different bodies objects does not exist. It proposed monitor one or two certain sections river, which characterize ecological state comprehensively, case emergencies non-stationary situations – conduct a complete chemical analysis water. For purpose it expedient use oxygen - dissolved biochemical consumption.
