Lung function and functional capacity among foundry workers using effective risk control measures.

Area of Science:

• Occupational Health
• Environmental Medicine
• Pulmonary Physiology

Background:

• Inhaled environmental dust can induce airway reactions and respiratory illnesses.
• Foundry work involves exposure to metals, posing potential respiratory risks.

Purpose of the Study:

• To assess lung function and functional capacity in Brazilian foundry workers exposed to metals with implemented control measures.
• To compare respiratory health outcomes between metal-exposed workers with controls and unexposed workers.

Main Methods:

• A cross-sectional study involving 108 workers from a bronze foundry and a university maintenance department in Brazil.
• Workers were categorized into a metal-exposed group with risk controls and an unexposed control group.
• Evaluations included respiratory symptom questionnaires, physical activity assessments, spirometry, peak expiratory flow, and the six-minute walk test.

Main Results:

• No significant differences were observed in spirometry or peak expiratory flow between the exposed and control groups.
• Functional capacity, assessed by the six-minute walk test, also showed no statistically significant differences between the groups.
• Personal characteristics and job tenure were similar across both study groups.

Conclusions:

• Foundry workers exposed to metals, when utilizing risk control measures, exhibited comparable lung function and functional capacity to unexposed individuals.
• The positive outcomes may be attributed to effective occupational hazard controls, age, and exposure duration.
• Continued monitoring through longitudinal studies is recommended for these workers.
