Cross-sectional Study of Health Effects of Cryolite Production
Occupational Health Clinics, Rigshospitalet Copenhagen, Denmark
A cross-sectional health study of 101 cryolite workers was performed, using spirometry and a questionnaire. Multiple regression analysis revealed a significant correlation between the index of smoking and a decrease in FEV1 (per cent). There was no significant correlation between work-related exposure and lung function.
Many cryolite workers described a group of symptoms appearing after 15 to 30 min of heavy dust exposure: nausea, followed by epigastric pain with relief after spontaneous or provoked vomiting. Thirty-four (336 per cent) workers complained of nausea, vomiting or diarrhoea in relation to work, compared to 38 per cent of 1752 men participating in the Copenhagen Male Study.
