Dust exposure and health complaints were recorded by means of personal samplers and a questionnaire for potroom workers in a primary aluminum plant situated at the west coast of Norway. The study revealed a higher dust exposure and a higher prevalence of acute health complaints during a period when fluoride recovery alumina from a dry-cleaning process was used compared to another period when pure alumina was used. Weather conditions and work conditions were otherwise similar during the two periods. This finding indicates that the use of recovery alumina increases the pollution of the work atmosphere and thereby causes more health complaints. The study also revealed a higher prevalence of pulmonary symptoms of a chronic recurrent nature than expected, in spite of the thorough selection which takes place before and during employment, and may therefore indicate that potroom workers are under the risk of developing chronic pulmonary disease.
粉尘暴露和健康问题通过个人采样器和问卷记录在案，这些采样和问卷针对的是位于挪威西海岸的一家初级铝厂的电解车间工人。研究显示，在使用来自干洗过程的氟回收氧化铝的时期，与使用纯氧化铝的时期相比，粉尘暴露更高，急性健康问题的发生率也更高。在这两个时期，天气条件和工作条件基本相同。这一发现表明，使用回收氧化铝会增加工作环境的污染，从而导致更多的健康问题。该研究还显示，尽管在就业前和就业期间进行了严格的筛选，但仍有比预期更高的慢性复发性肺部症状的发生率，这可能表明电解车间工人有患慢性肺部疾病的风险。
