Occupational asthma in an electronics factory.
نویسندگان
چکیده
Workers in a modern electronics factory were surveyed by questionnaire and lung function testing to see if there was evidence of widespread work-related respiratory symptoms. Of the responding workers exposed to solder flux fumes on the shop floor, 22% had work-related breathlessness or wheeze or both. Exposed workers had a lower FEV1 and FVC than unexposed workers. Work-related rhinitis was also present in 22% of exposed workers. The most likely cause for these results is sensitivity to colophony fumes, released from solder flux during soldering. Levels of solder flux fume were below the threshold limit value in this factory during the survey.

Occupational asthma in a factory making flux-cored solder containing colophony.
The prevalence of work-related wheeze and breathlessness was measured in factory employees manufacturing flux-cored solder. The flux contained colophony which was heated in the production process, exposing the workers to colophony fumes. Measurement of colophony in the breathing zone defined three grades of exposure with median levels of 1.92 mg/m3 (six subjects), 0.02 mg/m3 (14 subjects), and ...

متن کاملOccupational asthma in electronics workers caused by colophony fumes: follow-up of affected workers.
Thirty-nine electronics workers were investigated by bronchial provocation testing to soldering fluxes containing colophony and were followed up one to four years later. At presentation and on follow-up each worker had nonspecific bronchial reactivity measured with inhaled histamine, and also had detailed measurements of lung function and estimation of total immunoglobulin levels. They complete...

متن کاملWork-related respiratory disease in employees leaving an electronics factory.
Examination of the records of employees leaving an electronics factory over three-and-a-half years showed that a significantly greater proportion left the shop floor (where soldering took place) because of ill health than left the stores and office areas. This difference was largely due to work-related respiratory disease in those whose job was soldering. Shop floor workers leaving for health r...
