Air Quality samples detecting fine particulate matter (PM2.5) are being collected by volunteer cyclists. Samples are shared here to assist others in selecting the cleanest bicycling route.
Clusters (squares) are coloured based on the levels measured compared to the average taken that sample period.
The health hazards attributed to prolonged exposure to PM2.5 include cardiovascular and respiratory disease, asthma attacks, acute bronchitis and premature death.
Samples are clustered and displayed on the map as squares. Colours are based on the samples above the average during the period collected. As more samples are collected areas with chronically poor air quality will be revealed.
Current stationary PM2.5 air quality levels are also displayed as circles, updated every hour.
