[Substantiation of maximum permissible water level of the flotation reagent EFK-1].
Threshold concentrations of the flotation reagent EFK-1 in the water of reservoirs at 0.8 mg/l and 10.0 mg/l for organoleptic and total sanitary indices, respectively, were reported. Dl50 was 7469 mg/kg. The MAC of 0.8 mg/l for EFK-1 in the water of reservoirs (the limiting sign is organoleptic) was proposed.
