Regulation Return Water On Toxic Levels During Their Interception Into Water Bodies
In developing the substance interception maximum permissible into water bodies with return waters to the list of actual and approved indicators of return water quality was included the indicator of their toxicity level, determining by biotesting method. It considered the process of determining actual toxic levels maximum permissible by return waters, their assessment and correction, which intercept into water bodies. For presence or lack of toxic properties of return water the experimental data is obtained by determination of acute lethal toxicity on Ceriodaphnia crustaceans. Regulatory requirement to return waters to interception into water bodies is the lack of acute lethal toxicity for test-objects.
