STATION PAGES

Each page details the location of the station and the quality of the air being monitored. Highly accurate data is collected hourly every day of the year and checked for how often acceptable limits are exceeded.  For information on Local Air Quality Management please visit the DEFRA website http://laqm.defra.gov.uk/chart

  • Each monitoring station details a pollution summary level and graph charts, detailing levels of air pollutants monitored throughout the day / week based on the Daily Air Quality Index (DAQI)
  • The DAQI covers the 5 air pollutants most likely to affect health on a day to day basis;
        1. Ozone,
        2. Nitrogen dioxide (NO2),
        3. Sulphur dioxide (SO2),
        4. Particulate matter (as PM10),
        5. Fine particulate matter (as PM2.5)
  • The DAQI uses a scale of 1 to 10 to describe air pollution, divided in 4 bands as per the chart to the right
  • The pollutant concentrations that correspond to the air pollution bands are different for each pollutant, reflecting their typical concentrations in outdoor air, and the concentrations at which health effects may occur. For information on the Impact to your Health click HERE

 

The data is provided as a scale as defined by the Defra Air Pollution Health Bandings. We do not want anyone to panic but if you are concerned DEFRA provide a free automated telephone service on 0800 556677.
