Renal degeneration and CNS depression with paralysis of respiration and cardiac arrest have also resulted from acute inhalation exposure in animals. (13) Tests involving acute exposure of rats, mice and rabbits have demonstrated epichlorohydrin to have high acute toxicity from inhalation, oral, and dermal exposure. (4) Chronic Effects (Noncancer): Chronic occupational exposure of humans to epichlorohydrin in air is associated with high levels of respiratory tract illness and hematological effects (decreased hemoglobin concentration and decreased erythrocyte and leukocyte counts). (1,5) Chronic inhalation exposure has been observed to cause pulmonary effects including inflammation and degenerative changes in the nasal epithelia, severe lung congestion, and pneumonia in rats and mice.g/m3 ( mg/m3) would result in not greater than a oneinten thousand increased chance of developing cancer. For a detailed discussion of confidence in the potency estimates, please see IRIS. (2) EPA has calculated an oral cancer slope factor of x 103 (mg/kg/d)1. (2) Physical PropertiesThe chemical formula for epichlorohydrin is C3H5OCl, and its molecular weight is g/mol. (1,7) Epichlorohydrin is a volatile and flammable clear liquid at room temperature and i
