[Experimental substantiation of the maximum permissible concentrations of acetone and acetaldehyde in regenerated drinking water].

The paper presents experimental data indicating maximum permissible concentrations of acetone and acetaldehyde in reclaimed potable water used for different periods of time--up to 1, 3 or 12 months. The recommended concentrations for reclaimed water used for a year are 14.0 mg/l and 0.2 mg/l for acetone and acetaldehyde, respectively. The recommended levels for reclaimed water used for 1--3 months are 39.6 mg/l and 0.2 mg/l for acetone and acetaldehyde, respectively.
