Toxicity Profile
Route of ExposureInhalation; dermal. (2)
Mechanism of Toxicity'Oxadiazon is a member of the oxadiazole class of herbicides. While current data are limited, EPA has evidence that compounds within a class may share a common mechanism of toxicity. At this time, the Agency does not have sufficient data concerning common mechanism issues to determine whether or not oxadiazon shares a common mechanism of toxicity with other substances, including other oxadiazoles or other probable human carcinogens.' (2)
MetabolismAlthough, examples of all oxadiazole isomers are known, only the biotransformation pathways of compounds containing 1,2,4-oxdiazole rings have been reported so far. (1)
Toxicity ValuesLD50 >5000 mg/kg (oral, rat) (2); LD50 >2000 mg/kg (dermal, rabbit) (2); LC50 >1.94 mg/L (inhalation, rat) (2)
