AI Article Synopsis
- Researchers measured bicyclists' exposure to particulate matter (PM-10) while riding specific routes using GPS tracking.
- Personal exposure levels were recorded during rides, and pulmonary function tests were conducted before and after the rides, as well as up to 24 hours later.
- Significant declines in lung function were found immediately after biking, indicating that exposure to PM-10 on the road may harm bicyclists' respiratory health.
Article Abstract
We sought to measure bicyclists' roadway exposures to particulate matter and assess whether those exposures are associated with reduced pulmonary function. Thirty-one (31) volunteer participants riding bicycles on selected routes were tracked using the Global Positioning System. Personal exposures to particulate matter (PM-10) were measured during the rides and pulmonary function tests were administered at baseline, immediately after the ride, and 2 and 6-24 hours later. Post-ride decrements in pulmonary function were observed for several outcome measures, with the largest differences immediately post-ride. Statistically-significant declines in FEV (-38.42, 95% Confidence Interval (CI), -63.79 to -13.05 ml), FVC (-36.89, 95% CI, -62.96, -10.84 ml), and PEFR (-162, 95% CI -316.02 to -9.49 ml/sec) were observed for each increase in decile of peak exposure. PM-10 exposures encountered on roadways may put bicyclists at risk for pulmonary deficits.
