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 (33.6 per cent) workers complained of nausea, vomiting or diarrhoea in relation to work, compared to 3.8 per cent of 1752 men participating in the Copenhagen Male Study.
对101名冰晶石工人进行了一项横断面健康研究，采用了肺活量测定法和问卷调查。多元回归分析显示吸烟指数与第一秒用力呼气量（FEV1，百分比）下降之间存在显著相关性。工作相关暴露与肺功能之间无显著相关性。许多冰晶石工人描述了在重度粉尘暴露15至30分钟后出现的一组症状：恶心，随后是上腹部疼痛，自发呕吐或催吐后缓解。34名（33.6%）工人抱怨与工作相关的恶心、呕吐或腹泻，而参与哥本哈根男性研究的1752名男性中有3.8%有此类抱怨。
