1979) concluded that originally healthy survivors of phosgene intoxication recover fairly well over a period of years. However, individuals with preexisting chronic bronchitis may suffer significant chronic deterioration of lung function after acute phosgene intoxication, as an additional observation over 25 y showed. The individual, a light smoker who had mild chronic bronchitis since childhood, was exposed to phosgene and smoke at age 35. He developed severe pulmonary edema and was hospitalized for 7 weeks (wk) following the exposure.

APPENDIX 29 (74%). Thus, partial protection from phosgene-induced lethality was obtained by the phosgene pretreatment.

Guinea Pigs The few acute lethality studies of phosgene in guinea pigs do not contain experimental details such as strain or gender, number of animals exposed, or analytical methodology.
