Source information for DNEL derivation:
A key inhalation toxicity study was performed in Wistar rats (sighting exposure using 2 males and 2 females, followed by main study 5 males and 5 females) at target dust aerosol concentration of 5 mg/L Tin disulfide (Nagy, 2012). The animals were exposed for 4 hours using a nose-only exposure system, followed by a 14 day observation period. In the main study, the mean achieved atmosphere concentration was 5.02 mg/L. The MMAD was 3.91 µm ± 2.13 (GSD). Significant clinical signs were recorded on the day of exposure including laboured respiration and respiratory rate increase. All animals recovered by Day 2. Normal bodyweight gain was recorded, with the exception of one female where a slight bodyweight loss was recorded during the first three days of the observation period. No gross macroscopic observations were apparent at necropsy. LC50 > 5 mg/L.
A key 90- day repeated dose toxicity study in rats daily dosed with Tin sulfide was available (Slais, 2010). Four groups of rats (male/female Wistar rats) were daily administered with the test item suspension in 0.5% Carboxymethylcellulose (CMC) orally by gavage for 90 days.Three treated groups were administered with doses of 100, 300 and 1000 mg/kg bw per day. Dosing resulted in a slight increase in food consumption, associated with slight increases in body weight and serum glucose concentrations in females dosed at 1000 mg/kg. These were however not considered as adverse effects. Slight dose dependent decreases in serum Na and Cl, varying within physiological range, were observed. Except for the above mentioned changes, tin sulfide did not cause any negative effect on body weight, food consumption, ophthalmoscopy, hematology and clinical chemistry parameters and organ weights. Tin sulfide further did not cause any organ weight changes nor gross or histopathological changes in the liver, kidneys, gastrointestinal tract or other organs of survived animals indicative of a toxic effect. Under the test conditions used, 90 - day administration of the test item Tin sulfide to rats was safe and well tolerated up to the dose of 1000 mg/kg bw/day. The NOAEL was defined at 1000mg/kg and the NOEL at 300 mg/kg.
