Air quality across Purbeck is reviewed annually against the National Air Quality Standards set by the government. You can view the annual reports from the latest round of review and assessment below:

In 2020 the former local authority areas were amalgamated into one report.  If you require a copy of the Dorset Air Quality Annual Status Report 2020 please send a request to our business support team at  and a copy will be sent out to you.

What is the air quality like in Purbeck?

Air quality in Purbeck has been regularly assessed against the National Air Quality Standards and there have been no occasions when these reviews have identified that the objectives contained within the standards are being exceeded.

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 we will have to carry out a more detailed assessment for that pollutant. If the exceedance is confirmed then we 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.

Radon in Purbeck

Generally the majority of the Purbeck area is at low risk from radon, however there are some areas in the south of the district which the Health Protection Agency have identified as being at higher risk.

Radon is a radioactive gas which originates from naturally occurring uranium in the ground. The gas seeps into the atmosphere from the ground and can concentrate inside houses and other enclosed spaces especially if there is no ventilation. The levels of radon vary widely across the country according the types of rock which are present. Since the 1980's the government has had a policy of controlling levels of radon in houses by identifying those most at risk and installing simple remediation measures. Newly built properties are also protected in high risk areas.
