Groups of 6 male Crl:CD(50)BR rats were exposed to a combination of gaseous and aerosol atmospheres of RC-H-67836 for single, 4-hour perio4s. Under the conditions of this test, the ALC for RC-H-67836 was 320 mg/m3 of particulate combined with 2100 ppm of isopropano1. Based on the particulate concentration, this material is considered moderately toxic by inhalation.
