Proinflammatory effects and oxidative stress within human bronchial epithelial cells exposed to atmospheric particulate matter (PM2.5 and PM>2.5) collected from Cotonou, Benin

Key Points

• Bronchial epithelial cells exhibit significant oxidative stress after exposure to particulate matter.
• Exposure to PM2.5 and PM>2.5 notably increased levels of proinflammatory markers in these cells.
• The analysis assessed the impact of atmospheric particulate matter from Cotonou, indicating diverse sizes of PM.
• Findings suggest a need for better air quality measures to reduce health risks associated with air pollution.
