| Summary: | The work was initiated to study hygienic and toxicological indices of a synthetic analogue for the Sitophilus weevil aggregation pheromone. The toxicity testing of 5-hydroxy-4-methyl-3-heptanone demonstrated its extremely low toxicity for the warm-blood animals, as compared to the one of the typical pesticides. The average lethal dose of the product per orally administered to the white mice was established to be 4375.0 mg kg-1 LD16 and LD84 being 2225.0 mg kg-1 and 6550.0 mg kg-1, respectively. The average lethal dose for rabbits was 5900.0 mg kg-1 5-hydroxy-4-methyl-3-heptanone proved to have a mild skin and conjunctival irritant action, and equally mild functional cumulation. As to chronic toxicity, the acceptable daily dose of 4.3 mg/person/d was calculated and scientifically substantiated. The odor threshold was determined at the dose ranging from 0.35 to 0.7 mg l-1 with the practical limit ranging from 0.35 to 1.5 mg l-1, taste sensation threshold was found at the dose ranging from 1.0 to 3.0 mg l-1 with the practical limit ranging from 3.0 to 7.0 mg l-1 |
