What are the National Air Quality Standards?

The UK Air Quality Standards are set by central government for 7 pollutant parameters;

  • benzene

  • 1.3 butadiene

  • particulates (PM10)

  • carbon monoxide (CO)

  • sulphur dioxide (SO2)

  • nitrogen dioxide (NO2)

  • lead (Pb)

If an assessment of the air quality in Purbeck identifies an exceedance or likely exceedance of the objective for one of these pollutant parameters then the council will have to carry out a more detailed assessment for that pollutant. If the exceedance is confirmed then the council would declare an air quality management area (AQMA). An AQMA will define the area where the exceedance is occurring and will have an action plan to reduce the pollutant levels so that the objective is being complied with.

Purbeck District Council have carried out a detailed Air Quality Assessment of the Swanage Heritage Railway (pdf, 1Mb) (opens in a new window) which monitored the Sulphur Dioxide levels at the Northbrook Road Depot in April 2009.
