Air quality and pollution

Under the Environment Act 1995, we are required to regularly review and assess air quality within our area against national air quality objectives for key pollutants.  

If you think there is an issue with pollution or air quality in Lincoln being impacted by a premises or business you can report this to us online.

Report air quality problem       

The pollutants for which air quality objectives exist are:

  • Nitrogen dioxide     
  • Sulphur dioxide
  • Benzene   
  • 1, 3 - butadiene   
  • Carbon monoxide   
  • Lead   
  • Particulates   

A review of the Local Air Quality Management by central government placed focus on assessing and taking action on three pollutants in particular:

  • Nitrogen dioxide   
  • Particulates 
  • Sulphur dioxide

We produce annual reports on the state of air quality within the city, which now also provide updates on any action plan measures.

In order to keep a check on air quality, we maintain a number of monitoring sites for nitrogen dioxide and particulates throughout the city.

For areas in the city where the air quality is not likely to meet the required objectives we have to declare an Air Quality Management Area (AQMA). We then produce an action plan that seeks to identify ways in which the air quality can be improved within that area.

Taking action

We first completed a review and assessment of air quality in 2002, which resulted in an AQMA being declared as it was discovered that the levels of nitrogen dioxide were likely to exceed the annual mean air quality objective. This o rder was amended in February 2014 to include reference to the hourly mean objective due to the likely breach of this additional objective on parts of Broadgate. A further amendment was made to this AQMA in 2018 to reflect improvements in nitrogen dioxide levels and to remove reference to the hourly mean objective as this is no longer likely to be breached. 

A detailed air quality assessment in 2007 identified that the level of particulates were likely to exceed the national objectives. This meant that an AQMA for particulates was declared at the end of February 2008. This AQMA was revoked in August 2018 due to particulate levels consistently complying with the relevant objectives.

The main source of both nitrogen dioxide and particulates within the city is road transport.

Air Quality Action Plan 

We produced an Air Quality Action Plan in 2006, which outlines a number of potential measures that may be taken to improve air quality. As the majority of the proposed actions are aimed at trying to reduce the impact from road transport, the action plan has been incorporated into Lincolnshire County Council’s current Local Transport Plan through the Lincolnshire Strategic Air Quality Partnership. 


Information on air quality can be obtained by contacting the Pollution Control Team or by reviewing the latest reports in the downloads section.
