Yŏngju's air quality reflects the Gyeongbuk Nakdong River upper valley position at 210 metres, with vehicle traffic on surrounding roads and the apple farming, traditional Korean ginseng — Yeongju producing Korea's finest ginseng — and manufacturing corridor contributing local sources. Seasonal Chinese dust transport elevates PM10 during spring yellow dust episodes, while the surrounding Sobaek mountain ranges create topographic variation and Yeongju generally maintains moderate South Korean inland Gyeongbuk provincial city readings throughout most of the year.
