Abstract

Background: Rapid industrialization has significantly altered air quality profiles in urban centers, leading to adverse health outcomes. This study investigates the correlation between key air pollutants (PM_2.5, PM₁₀, NO₂, SO₂) and the prevalence of respiratory diseases in industrial zones compared to non-industrial control areas. Methods: A retrospective ecological study was conducted utilizing data from 2019 to 2023. Air quality data was obtained from monitoring stations, while respiratory morbidity data (COPD, asthma, acute respiratory infections) was collected from regional health bureaus. Statistical analysis involved Pearson correlation coefficients and multiple regression models. Results: The study revealed a statistically significant correlation between elevated levels of particulate matter (PM_2.5) and hospital admissions for acute asthma exacerbations (r = 0.72, p < 0.01). Residents in the industrial zone exhibited a 35% higher incidence of chronic respiratory conditions compared to the control group. Conclusion: There is a direct, quantifiable link between industrial air pollution and respiratory morbidity. The findings necessitate urgent policy interventions, including stricter emission controls and the establishment of green buffer zones to mitigate public health risks.
