Statistics from Altmetric.com

Fluoropolymer-associated illnesses induced by direct inhalation of fluorocarbon monomers and pyrolysis products (FMPPs) have been rarely reported. We report 11 cases of accidental inhalation of FMPPs, including 5 cases of acute respiratory distress syndrome (ARDS) and 1 death.

Twelve workers from a local factory presented dry cough on a January morning after their night shift. They were treated with supplemental oxygen in a local hospital, and one of them died of respiratory failure that evening. Open-air discharge of FMPPs by a neighbouring factory between 20:00 and 00:00 the previous night was confirmed after investigation. During the disposal stage of FMPP residue generated during production of fluorocarbon coating, the step of spraying water over the residue was inadvertently left out, leading to the accident. The workshop the patients worked at was about 35 m from the site of discharge. Perfluoroisobutylene, hydrogen …
