[Hygienic rationale maximum allowable concentrations of 1,2,4-triazole in atmospheric air]. / Gigienicheskoe obosnovanie predelno dopustimykh kontsentratsii 1,2,4-triazola v atmosfernom vozdukhe.

Toxicological study of the 1,2,4-triazole determined the maximum one-time MAC of it in the ambient air at level of 0,1 mg/m3, average daily MAC of it - 0,05 mg/m3.

Average daily MAC of the sebacic acid in the ambient air established at the level of 0.05 mg/m3 (3-d class of hazard). Data of acute and chronic experiments were noted.

[Substantiation of the maximum permissible level of ambush in the air]. / K obosnovaniiu predel'no dopustimoi kontsentratsii ambusha v atmosfernom vozdukhe.

The article is devoted to the substantiation of ambush MAC in the ambient air. Resorptive action of the insecticide on the organism of experimental animals has been studied under the conditions of 3-month 24-hour chronic inhalational exposure. On the basis of the studies the maximum single and average 24-hour ambush MACs in the ambient air have been developed, which are 0.05 and 0.03 mg/m3 respectively.
