Sulfur Dioxide- and Fluoride-Associated Declines in Lung Function Over an 11-Year Observation Among Aluminum Smelter Workers.

ABSTRACT:

Background

Work exposure-related declines in lung function among aluminum smelter workers are well documented, yet task-varying exposures are likely to contribute differently to respiratory outcomes. This study aimed to assess the association between potroom exposure and lung function changes over time among aluminum smelter workers.

Methods

A retrospective review of spirometric assessments of 265 potroom workers and their exposure to sulfur dioxide (SO₂) and fluoride was conducted. Cumulative exposure was described through job exposure matrices by job titles and exposure across the lifetime of employment. Associations between exposure and lung function were determined using mixed-effect models and a 1-year lag exposure.

Results

Exposures were within the pr
