Excerpts from Documentation for IDLHs

Animal data: No acute intoxication occurred in animals exposed to concentrations as high as 10,000 mg/m3; serious pathologic changes occurred only at concentrations ranging from 1,000 to 2,000 mg/m3 in 1hour exposures on alternate days for 2 months [Roshchin 1952]. It was also reported that exposure of rats to 40 to 80 mg/m3 for 2 months caused bronchitis, interstitial sclerosis, and perivascular edema [Clayton and Clayton 1981].
