The first histologically and clinically documented case of pneumoconiosis
caused by prolonged polyvinyl chloride (PVC) inhalation was described in
1970. A series of human epidemiological as well as some experimental studies
confirmed the existence of PVC pneumoconiosis. Pyrolytic products of PVC,
of vinyl chloride and of plasticisers and stabilisers may irritate the respiratory
organs, causing fibrosis, asthma, bronchitis and even cancer of the lung. Workers
employed in PVC plants are at high risk with respect to PVC-induced lung
disease.
