چکیده

The aim of the study is to investigate risks, prevalence, clinical forms of chronic bronchopulmonary diseases (CBPD) in aluminum workers and assess whether asthma and other respiratory conditions occur excessively among pot workers. The survey of 479 workers at Kandalaksha aluminum smelter has shown that the most prevalent respiratory disease is chronic bronchitis (CB) detected in 13,4-17,0 % of workers. Chronic obstructive pulmonary disease (COPD) and asthma (all forms) are diagnosed much less frequently (2,9 % each). The development of CB and COPD is closely associated with the degree of exposure to tobacco smoke and harmful production factors. Work experience lasting 6-14 years has led to an increased risk of CB / COPD to 5,11 (CI 1,26-20,80), work experience lasting for more than 14 years – up to 7,78 (CI 1,93-31,33) as compared with the employment duration of less than 6 years. CB/COPD are diagnosed in 31,3 % of smokers and only in 5,8 % of non-smokers (p < 0,01). In case of asthma, such a link is missing. Potroom asthma should be highlighted among the various pathogenetic variants of the disease identified in the aluminum industry workers. This variant of asthma with currently unclear causal factors and features of the pathogenesis is a specific health disorder to a given occupational group. The prevalence of CB, COPD and asthma (all forms) do not differ significantly among workers employed directly in servicing the electrolysers, and workers in other parts of the production of aluminum. The only exception is potroom asthma that develops more frequently in the exposed group of pot and anode operators. It has been concluded that the medical and social significance of potroom asthma requires further investigation of the unknown features of etiology and pathogenesis of this disease. Аннотация. Исследованы факторы риска, распространенности и клинических форм хронических бронхолегочных заболеваний (ХБЛЗ) у работников алюминиевой промышленности, а также особенности развития ХБЛЗ и астмы у работников, непосредственно обеспечивающих функционирование электролизеров. Анализ состояния здоровья 479 работников Кандалакшского алюминиевого завода показал, что наиболее распространенным респираторным заболеванием является хронический бронхит (ХБ), выявляемый у 13-17,4 % рабочих. Значительно реже диагностировались хроническая обструктивная болезнь легких (ХОБЛ) и астма (все формы) – по 2.9 %. Развитие ХБ и ХОБЛ оказалось тесно связанным со степенью экспозиции к табачному дыму и вредным производственным факторам. Стаж работы продолжительностью 6-14 лет приводил к увеличению риска развития ХБ/ХОБЛ до 5,11 (CI 1,26-20,80), а более 14 лет – до 7,78 (CI 1,93-31,33) по сравнению с длительностью работы менее 6 лет. ХБ / ХОБЛ были диагностированы у 31,3 % курящих работников и только у 5,8 % некурящих лиц (p < 0,01). В отличие от ХБ / ХОБЛ связь развития астмы с курением и продолжительностью воздействия вредных производственных факторов не выявлялась. Среди патогенетических вариантов астмы, выявляемых у работников алюминиевой промышленности, следует выделить "potroom" астму. Этот вариант астмы с невыясненными в настоящее время причинными факторами и особенностями патогенеза является специфическим заболеванием для данной профессиональной группы. Показатели распространенности ХБ, ХОБЛ и БА (все формы) существенно не отличаются у работников, занятых непосредственно обслуживанием электролизеров, и работников других участков производства алюминия. Только "potroom" астма развивается чаще у более экспонированной группы электролизников и анодчиков (2,9 % работников). Сделан вывод о том, что медико-социальная значимость "potroom" астмы обусловливает необходимость дальнейшего изучения неясных вопросов этиопатогенеза данного заболевания.

Mineralogical analysis of the respiratory tract in aluminium oxide-exposed workers.

A retrospective study was conducted in order to characterize the retention of fibrous and nonfibrous mineral particles in the respiratory tract in subjects with previous occupational exposure in the aluminium industry. Bronchoalveolar lavage (BAL) fluid (three samples) or lung parenchyma (two samples) were studied using analytical transmission electron microscopy in five patients. A high concen...

Occupational asthma caused by aluminium welding.

Work-related asthma has been documented in workers employed in the primary aluminium industry and in the production of aluminium salts. The role of aluminium in the development of occupational asthma has, however, never been convincingly substantiated. We investigated a subject who experienced asthmatic reactions related to manual metal arc welding on aluminium. Challenge exposure to aluminium ...
