Longitudinal study assesses air quality impacts on urban health outcomes, suggesting regulatory measures are effective.
Key Points
There was a year-by-year decrease in PM2.5 and NO2 concentrations, showing the effects of improvements in city infrastructure and regulation.
Pollutants like O3 and seasonal spikes were linked to increased respiratory and cardiovascular disease rates among vulnerable populations.
Using analyses including the Mann-Kendall trend test and linear regression, health correlations were quantified while accounting for confounding factors.
Findings highlight the need for ongoing air quality monitoring to protect health in rapidly urbanizing megacities.
