Chemical Pneumonitis due to Exposure to Waterproofing Spray Containing Perfluoroalkyl Acrylate Copolymer

초록

Waterproofing spray is used to ensure that clothing, includingmountain wear, leather, and other surfaces are waterproof. Respiratory illnesses related to the use of waterproofingspray have been reported globally. The composition ofwaterproofing spray varies depending on the manufacturer. We treated a patient with chemical pneumonitis and alveolarhemorrhage due to exposure to waterproofing spraycontaining perfluoroalkyl acrylate copolymer. We diagnosedthe patient with chemical pneumonitis and alveolar hemorrhagebased on computed tomography (CT) and bronchoalveolarlavage (BAL) test performed within 24 h aftersymptom occurrence. We believe that further study regardingthe exact mechanism of pulmonary toxicity for waterproofingagents is required.
