An indicator that describes the amount of dissolved oxygen (mg O₂/L) that microorganisms consume when breaking down organic matter in water over 7 days
Shows the level of organic pollution and biodegradability of water
A high BDS₇ value indicates intensive organic pollution, which can lead to oxygen deficiency in water bodies, posing a danger to fish and other organisms
This indicator is one of the main environmental parameters used to assess the impact of wastewater and the condition of water bodies
In occupational health and safety assessments (water quality control, sanitary risk)
In the control of industrial facilities (wastewater analysis, monitoring of technological processes)
In environmental studies (assessment of the condition of water bodies, organic pollution monitoring, identification of pollution sources)
