Asthma due to grinding epoxy resin cured with phthallic anhydride


Dr M. J. Ward, Department of Thoracic Medicine, City Hospital, Nottingham NG5 1PD


A man developed asthma after grinding epoxy resin moulds made from bisphenol-A, with phthallic anhydride as a hardener. He was shown to have a dual asthmatic response after the inhalation of phthallic anhydride fumes. It is postulated that his asthma was caused by the release of phthallic anhydride during the grinding of cured mouldings.
