[Experimental study and standardization of propanide in water]

Hygiene-toxicological and ecotoxicological studies of amide herbicide propanide are performed in view of its standardization in waters. Experiments are carried out for defining its effect on the organoleptic quality of the waters, ecotoxicological effect in water medium and toxic effect on warm blooded organisms. Threshold and subthreshold concentrations and doses of harmful effect are defined. Differentiated hygiene norms (MAC) are developed for toxicological resources; for first category (after toxicological indication)--0.1 mg/l; for second and third (after ecotoxicological symptom) respectively 1.0 mg/l and 2.0 mg/l.
