Respiratory Abnormalities among Occupationally Exposed, Non-Smoking Brick Kiln Workers from Punjab, India

Area of Science:

• Occupational Health
• Environmental Medicine
• Pulmonology

Background:

• The brick manufacturing industry in India is a major employer, with workers facing significant occupational exposure to air pollutants.
• Limited research exists on the respiratory health impacts on brick kiln workers.

Purpose of the Study:

• To assess respiratory impairment in brick kiln workers.
• To determine the relationship between exposure duration and lung function decline.

Main Methods:

• A cross-sectional study involving 110 non-smoking male brick kiln workers (aged 18-35) in Punjab, India.
• Spirometric parameters were compared to 90 age-matched unexposed individuals.

Main Results:

• Brick kiln workers exhibited significantly reduced forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), forced mid-expiratory flow rate (FEF25-75%), and peak expiratory flow rate (PEFR) compared to controls.
• Workers with over 8 years of exposure showed significantly lower lung function values than those with less than 8 years of exposure.

Conclusions:

• Occupational exposure to workplace pollutants in brick kilns is significantly associated with lung function deterioration.
• The duration of exposure is a critical factor in the extent of respiratory impairment among these workers.
