title: Sensory irritating properties of cyanuric chloride as revealed with plethysmographic method.
abstract: Sensory respiratory irritation properties of cyanuric chloride (2,4,6-trichlorotriazine; CC) were studied in mice. For this purpose, the respiratory rate was measured in Balb/C male mice by means of the whole body plethysmographic method. Each animal was placed in a body plethysmograph attached to a small (0.25 m3) dynamic inhalation chamber and exposed to various concentrations (2.1, 6.7, 9.1, 11.7 and 14.6 mg/m3) of CC. Respiratory rates were recorded before, during and after termination of the exposure. It was found that exposure to CC caused a concentration-dependant decrease of respiratory rates in mice. After termination of exposure fast and full recovery of respiratory rates were observed within 5 minutes. RD50 value calculated with probit method was established as 5.9 (1.3-13.9 for 95% confidence limits) mg/m3. The slope of the dose response curve was 1.366 (0.78). It is concluded that cyanuric chloride is a strong respiratory irritant.
