What affects air quality for runners in Beijing
Beijing's air quality reflects both urban emissions and regional transport within a broad northern plain setting. Traffic and combustion sources remain important, but citywide episodes often involve secondary particle formation and imported pollution. Under unfavorable meteorology, concentrations can increase rapidly and persist despite local control measures.
