Male and female albino Wistar rats were exposed to concentrations of 0, 1, 10 or 20 ppm formaldehyde vapour during 6 h/day, 5 days/wk for 13 weeks. Treatment-related changes observed at 20 ppm included in both sexes: stared coats, uncoordinated locomotion and excitation during the first 30 minutes o

β¦ Synopsis
Azinphos-methyl was evaluated for its subchronic inhalation toxicity.
The exposure of rats to concentrations of 0.195, 1.24, and 4.72 mg/m 3, respectively, for 12 weeks, 6 hrs daily, 5 times weekly, resulted in effects only in those animals which inhaled aerosols of the highest concentration. This group showed a significant depression of the cholinesterase activity in plasma and erythrocytes. The males of this group had a lower body weight gain. The results are in agreement with the established maximum allowable concentration of 0.2 mg/m 3.
