- Executive summary:
The acute oral toxicity of undiluted Methyltin tris (2ethylhexylthioglycolate) was evaluated in compliance with the conditions specified in the regulation for the enforcement of the Federal Insecticide, Fungicide, and Rodenticide Act (40 CFR), the Toxic Substances Control Act (40 CFR) and OECD Guideline 401.
The test material was administered undiluted to groups of five male and five female Sprague Dawley rats at a dose level of 3.15 g/kg, 1.25 g/kg, 0.80 g/kg, and 0.50 g/kg. Following a single oral administration, the animals were observed for 14 days.
Based on the mortality observed, the acute oral LD50 value was calculated to be 0.88 g/kg with the 95% Confidence Limits of 0.67 g/kg and 1.15 g/kg. Clinical signs noted during the observation period included varying degrees of depression, comatose, piloerection, eye squinting, hunched posture, labored breathing, ataxia, fecal stains, urine stains, and masticatory movement. All surviving animals exhibited body weight gain at day 14. Gross necropsy findings for animals that died during the observation period included lungs pale, reddened, or mottled, liver mottled, liver pale and mottled with lower edge of lobes of liver darkened, areas of liver exhibit white blanching, areas of liver pale, spleen pale, darkened, or mottled, pancreas darkened, kidneys pale and/or congested, kidneys enlarged, stomach distended with gas, intestines reddened, intestines distended with gas, intestines contain a viscous yellow to orange fluid, urinary bladder contains a pale red fluid, and external staining. No gross pathological changes were noted in animals that survived the observation period.
