Air quality

Local authorities have a duty to monitor air quality within their areas having regard to national air quality objectives and standards and report this information to the Department for Environment, Food and Rural Affairs (DEFRA) on an annual basis. There are seven pollutants which we are required to consider under European and UK Law, these include lead, benzene and sulphur dioxide.

Air quality in Wiltshire is predominantly good with the majority of the county having clean, unpolluted air. There are however a small number of locations where the combination of traffic, road layout and geography has resulted in exceedances of the annual average for nitrogen dioxide (NO2) and fine particulates (PM10).

All information relating to air quality monitoring in Wiltshire can be found on the Wiltshire Air Quality website.
