nationally the usage of wood burning stoves is on the increase, and emissions form them are a relatively small but important contributor to particulate matter in urban areas. Air Quality Monitoring results Air quality monitoring data for the three automatic monitoring stations in Eastleigh for 2018 so far can be found in appendix 3. The Council currently monitors nitrogen dioxide (NO2) and particulate matter which is 10 micrometres or less (PM10) concentrations in Eastleigh.
