Title Exposures to respirable, airborne Penicillium from a contaminated ventilation system: clinical, environmental and epidemiological aspects
Bibliographic information Mar. 1983, Vol.44, No.3, p.161-169 Illus. 36 ref.
Abstract Symptoms compatible with hypersensitivity pneumonitis (HP) in 2 of 14 employees in a clerical office prompted an investigation. Improperly maintained forced-air heater-cooler units were found to be grossly contaminated with predominantly Penicillium moulds. Air sampling and analysis confirmed the presence of high concentrations of the same moulds in the office air. Despite a documented reduction of airborne fungi to background exposure levels after clean-up of the forced air units, a worker with persistent alveolitis has had occasional recurrences of symptoms consistent with HP. A multidisciplinary approach to research in establishing guidelines for control of occupational and non-occupational exposures to respirable fungal organisms which may contaminate cooling, heating and humidifying systems is described.
