There are two techniques used to monitor air quality:
1. Non-Automatic Sampling. Diffusion tubes located around the District sampling for Nitrogen Dioxide and Benzene.
2. Automatic Continuous Monitoring. Monitoring stations which report concentrations of nitrogen dioxide, sulphur dioxide and PM10 particulate matter automatically every hour of the day.
