ENVIRONMENTAL CONDITIONS
not reported

Administration / exposure

Route of administration:
oral: gavage
Vehicle:
water
Doses:
4.0, 8.0, or 16 mL/kg bw, equivalent to 3.55, 7.10, or 14.21 g/kg bw
No. of animals per sex per dose:
5 males
Control animals:
not specified
Details on study design:
Animals were observed for signs of toxicity after dosing, and throughout the 14-day observation interval. Animals were weighed prior to dosing and at the end of the observation interval. Animals that died on study were subjected to necropsy; surviving animals were sacrificed at the end of the observation interval and necropsied.
Statistics:
Thompson's method of calculating the LD50 was applied to the 14-day mortality data.
