What affects air quality for runners in Buenos Aires
Buenos Aires air quality is shaped by dense road traffic, urban activity, and changing airflow from the Río de la Plata. Nitrogen dioxide peaks are usually strongest near major avenues and busy intersections, while particulate pollution can extend across broader neighborhoods during calm periods. Local wind shifts often determine which districts clear first.
