What affects air quality for runners in Shanghai
Shanghai combines dense urban traffic, major port operations, and heavy regional economic activity, creating complex pollution dynamics. Nitrogen dioxide peaks are common near transport corridors, while particulate levels reflect both city emissions and broader Yangtze Delta influence. Humid conditions can modify particle chemistry and affect perceived haze intensity.
