Penrose station was established in November 2000 and we currently monitor NO2, SO2, PM10 and PM2.5.
Air quality is generally good for most of time in many areas. Air pollution sources are mainly from vehicle emissions (particularly at busy roadside), residential home heating (during winter) and some industrial activities. The monitored CO, SO2 and NO2 concentrations meet national environmental standards for air quality. PM10 and PM 2.5 concentrations usually meet national environmental standards for air quality and guidelines although exceedances occur occasionally.
