English term

oral rat (sic!)

English Medical toxicology
Toxicology / hazard warnings and information:

"Single dose oral toxicity is low: LD50 (oral rat) >5000 mg/kg."

"Inhalation: LC50 (4 hours rat): 100 - 360 mg/m3 (aerosol and vapour)."

First I thought "rat" stands for "ratio" or "ration", but then I found this in the same text:

"Skin contact: Dermal LD50 (rabbit) >9000 mg/kg."

Shall I translate "rat" as an actual rat? Seems so strange here...

rat

yes, you should translate it as a rat. It's the laboratory animal in this context. Rabbits are also used for experiments.
