Henderson monitoring stations was established in December 1993 and we currently monitor NO2, PM10 and Black Carbon.
Air quality is generally good for most of time. Air pollution sources are mainly from residential home heating (during winter) and vehicle emissions (particularly at busy roadside). The monitored NO2 concentrations meet national environmental standards for air quality. PM10 concentrations usually meet national environmental standards for air quality.
