The air quality is generally good for most of the time. The main sources of air pollution are residential home heating during winter and vehicle emissions, especially in busy roadside areas. The monitored concentrations of NO2 meet national environmental standards for air quality. While PM10 concentrations usually meet national environmental standards for air quality, occasional exceedances do occur.
