pneumonia caused by inhalation of toxic gas, such as phosgene or chlorine, used as weapons of war; exudation into alveoli causes the lungs to be edematous and hemorrhagic; large amounts of fluid that fill the air passages block gaseous exchange; recovery occurs, permanent damage of the lungs remains, and recurrent pulmonary infections are common.

chemical pneumoniaChonic lung inflammation secondary to inhaled toxins—e.g., phosgene or chlorine, organic dust, fungi or spores.
Cough, fever, shortness of breath, wheezing, decreased O2 exchange. Acute: oedema, hypoxia; chronic: interstitial fibrosis, possibly respiratory failure.
Chronic interstitial lung changes, pulmonary oedema.
