- Executive summary:
This acute inhalation toxicity study of the test substance was carried out in Wistar rats as per the OECD guideline 403, OPPTS 870.1300. Five male and five female rats were exposed nose only to 5.00 mg/L IN-QEK31 for 4 hours. The rats were observed for mortality and clinical signs of toxicity during the exposure and daily for 14 subsequent days. Body weights were measured on test days 0, 1, 3, 7 and 14.
All rats exposed to 5.00 mg/L survived the exposure and the subsequent 14-day recovery period. The rats demonstrated no clinical signs of toxicity up to day 14. Male rats exposed to 5.00 mg/L test substance demonstrated body weight gain (up to 3 to 13 g) and four female rats demonstrated body weight gain (up to 2 to 11 g) on test day 1. One female rat demonstrated body weight losses (up to 5 g) on test day 1. Three male rats demonstrated body weight losses (up to 2 to 9 g) and two male rats demonstrated body weight gain (up to 4-6 g) on test day 3. Two female rats demonstrated body weight losses (up to 3-8 g) on test day 3 and the other female rats demonstrated body weight gain (up to 4-7 g). All the rats demonstrated body weight gains on test days 7 & 14. No abnormalities were observed in the gross pathological examination of animals conducted on day 14.
Under the conditions of this study, the 4-hour inhalation median lethal concentration (LC50) for the test substance was greater than 5.00 mg/L.
