“…In a recent study, SARIC and MARELJA [54] found that 67% retained their bronchial hyperreactivity after cessation of exposure, even though symptoms improved or disappeared in 60% of the workers. In a Norwegian study of 12 subjects relocated because of potroom asthma, a twofold increase in PC 20 was observed in 7 of the 8 subjects who were hyperreactive at the time of relocation [10]. Symptoms improved or disappeared in seven workers during 2 yrs of follow-up, whilst no improvement in FEV 1 was observed.…”

ABSTRACT: Work-related asthma in aluminium potroom workers, is reviewed and discussed, mainly on the basis of own investigations. The occurrence of work-related asthma has been shown to be associated with the duration of potroom employment, although the prevalence of asthmatic symptoms is not significantly different from that of the general population. Typical manifestations of occupational asthma are described in potroom workers, and a close relationship between the levels of fluoride exposure and work-related asthmatic symptoms has been observed. The existence of occupational asthma in aluminium potroom workers has been confirmed by characteristic patterns of repeated peak flow measurements, supported by changes in methacholine responsiveness in workers with suspected work-related asthma. However, no immunological test is available to establish the diagnosis. Methacholine challenge appears to be inappropriate for screening aluminium potroom workers in order to detect work-related asthma. Current smoking, but not self-reported allergy, is a risk factor for potroom asthma. A family history of asthma and previous occupational exposure may have some effect on the risk of developing symptoms.The prognosis of potroom asthma seems to depend on early replacement to unexposed work. The pathogenetic mechanisms are unknown, although some studies indirectly imply a hypersensitivity reaction.Future studies involving specific bronchial challenge appear to be necessary to find the causal agent(s) of aluminium potroom asthma.

“…The registration of chronic symptoms is of the same magnitude or slightly lower than that found by Eduard and Lie [1981]. They demonstrated a relationship between dust exposure and pulmonary complaints without, however, distinguishing between smokers and nonsmokers.…”

“…Pulmonary fibrosis (aluminosis) may occur after exposure to y-A1203 [Stacy et al, 19591. The studies of Eduard et al [1980] and Eduard and Lie [1981], which were performed at the same plant as the present investigation, revealed a higher prevalence of pulmonary symptoms of a chronic recurrent nature than expected, and there may be an augmented risk for workers to develop chronic pulmonary lung disease, although this question is still being disputed [Bjdrseth, 19831. Respiratory complaints have also been described, and a doseresponse relationship between personal exposure to total dust and subjective acute airway complaints has been shown [MowC, 19761. Our aim in the present study is to use the AM numbers as a dose indicator and look for a covariation between AMcounts and chronic symptoms/subjective complaints. The hypothesis is that the AMtest can serve as an effect indicator as well as a dose indicator.…”

“…Information on the prevalence of chronic symptoms and acute complaints may be obtained from self-administered questionnaires [Eduard and Lie, 1981;van der Lende and Orie, 1972;Lebowitz and Burrows, 1976;Gulsvik, 19791. The same type of questionnaire was used in the present study and was distributed to the workers at the aluminum plant and to the reference group in advance and collected at the time of sampling the expectorates.…”

According to a method (the AM-test) previously developed by us, the counting of alveolar macrophages (AM) from expectorates provides an estimation of the potential pulmonary insult from occupational air pollution +/- smoking. In this article we demonstrate a relationship between the number of AM and self-registered pulmonary symptoms and complaints. Employees from different workplaces in a primary aluminum reduction plant gave expectorate samples for the AM-test. A gradient in the number of AM was observed, with increasing AM numbers from the controls to the administration employees to the potroom workers, who had the highest numbers. Pulmonary symptoms and complaints were recorded by means of a questionnaire. A clear covariation between AM numbers and respiratory symptoms and complaints was observed and was most pronounced at the highest pollution levels (in the potrooms). We therefore suggest that the AM-test may serve as an effect indicator as well as a dose indicator.
