Sanhe's air quality reflects the flat Hebei North China Plain position adjacent to Beijing's eastern metropolitan corridor, with vehicle traffic and the manufacturing, logistics, and residential corridor contributing local sources. The Beijing-Tianjin-Hebei regional background and winter anticyclonic inversions elevate readings and Sanhe generally maintains moderate to elevated Beijing eastern metropolitan fringe readings throughout the year.
