Indoor air quality and its effects on lung function and respiratory symptoms among textile spinning mill workers in India.

BackgroundTextile spinning mill workers are exposed to airborne cotton dust and particulate matter, which are associated with respiratory symptoms and impaired lung function.ObjectiveThis study aimed to evaluate the prevalence and severity of respiratory symptoms among textile spinning mill workers and to assess the impact of occupational dust exposure on pulmonary function.MethodsA cross-sectional study was conducted among 180 textile spinning mill workers. Data were collected using a structured questionnaire to assess respiratory symptoms and through pulmonary function tests to evaluate lung function. Indoor air quality was monitored by OIZOM Polludrone to measure particulate matters (PMand PMconcentrations), which were compared to permissible thresholds.ResultsThe study found that the levels of PMand PMin the textile spinning mills were much higher than the recommended limits, averaging 186.02 µg/mfor PMand 826.66 µg/mfor PM. The results showed a high rate of respiratory problems among workers. About 15-20% had byssinosis, 10-12% had chronic bronchitis, and 8-10% had asthma.ConclusionMany workers also reported frequent coughing, chest tightness, and shortness of breath. Pulmonary function tests indicated reduced lung function in workers exposed to cotton dust.

Pulmonary function tests indicated reduced lung function in workers exposed to cotton dust. Key measures like FEVand FVC were lower than normal, and the FEV/FVC ratio suggested obstructive lung conditions. The study highlights the severe respiratory health risks associated with cotton dust exposure in textile spinning mills. The findings emphasize the need for improved occupational health and safety measures to reduce dust exposure and protect worker health.
