Executive Summary: Air Quality in Our Area
Air Quality in East Dunbartonshire
This report is the 2022 Annual Progress Report undertaken in accordance with East Dunbartonshire Council’s statutory obligation under the National Air Quality Strategy.
The report considers measured pollutant concentrations across East Dunbartonshire for the calendar year of 2021 and considers the potential for exceedences of the air quality objectives.
In East Dunbartonshire, the main pollutants of concern are NO2, PM10 and PM2.5 and the source of pollutant is mainly due to the volume of traffic and congestion. Across East Dunbartonshire, traffic flows have returned to pre pandemic levels however, pollutant levels remain satisfactory.
East Dunbartonshire Council has four continuous automatic analysers; one in Bishopbriggs, one in Bearsden, one in Kirkintilloch and one in Milngavie. This equipment downloads automatically and pollutant levels can be viewed via the Council web page or Scottish Air Quality website.
Monitoring over 2021 indicates a continuing overall downward trend in line with what has been experienced across Scotland over the last few years and this trend continued on the whole for all pollutants. The annual mean NO2 level at three of our four automatic monitoring sites rose slightly post pandemic to levels between 16 and 24 µg/m3 as opposed to the objective level of 40µg/m3 however, the level at our Bishopbriggs site dropped from 20 µg/m3 in 2020 to 18.6 µg/m3 for 2021.Unfortunately, data capture at the Bishopbriggs site was poor resulting in annualisation being required with a final annual mean NO2 of 16.8 µg/m3 being recorded for 2021.Milngavie recorded the lowest annual mean level of 16 µg/m3. It was 15 µg/m3 at the same site the previous year following various periods of lockdown.No exceedences of the hourly mean were recorded.
All four sites recorded levels well below 10% of the air quality objective for annual mean NO2.
There is no discernible pattern to annual mean PM10 levels during 2021. PM10 levels at three out of four of our automatic monitoring sites recorded slight increases varying between 9.5 µg/m3 at Bearsden and 10.7 µg/m3 at Kirkintilloch however, the level at our Milngavie site dropped from 10 µg/m3 in 2020 to 8.7 µg/m3 in 2021; all well below the annual mean objective level of 18µg/m3.
Annual mean PM2.5 levels at all four sites are well within the Scottish objective level of 10 µg/m3. Although annual mean PM2.5 levels increased slightly at three of our four sites, the increase was very slight and the overall level at Bishopbriggs decreased, dropping from 6 µg/m3 in 2020 to 5.9 µg/m3 in 2021.
There are no new major sources of emissions although the installation of domestic wood burning stoves, and complaints concerning their use, continue to be received.
There are two AQMAs in East Dunbartonshire: one in Bishopbriggs and one in Bearsden. No new AQMAs were declared during 2020. NO2 tubes which were added to the network to further investigate background levels have mostly been removed.
East Dunbartonshire Council intend to revoke the Bearsden AQMA designation for exceedences of both the NO2 and PM10 annual mean however; it is not our intention to revoke the Bishopbriggs AQMA at this stage. Committee approval for revoking the Bearsden AQMA was forthcoming in November 2021 and the revocation has been approved by both the Scottish Government and Sepa. Statutory consultation yielded no adverse comments.
Air quality is a material consideration in terms of planning which means that all local development is considered in terms of air quality to ensure implications are examined and considered in advance and appropriate consultation takes place with such partners as the Scottish Environment Protection Agency (SEPA), Transport Scotland and Scottish Natural Heritage (SNH).
Actions to Improve Air Quality
East Dunbartonshire has a successful iBike programme operated in partnership with Sustrans Scotland. The iBike officers work intensely across local schools delivering practical lessons on active travel embedded within the school curriculum. This includes learning to cycle sessions, bike skills sessions, led rides, led walks, bike maintenance sessions, bike clubs etc. This encourages younger people to travel more actively and evidence shows that iBike schools tend to have higher levels of active travel on average than non-iBike schools.
Officers across the Council worked with Education to deliver the Climate Change Challenge in 2021. This included delivering 'Meet the expert' sessions where staff attended online question and answer sessions with local primary pupils about their individual relevant subject and created materials to help them create projects and ideas that will help tackle climate change. There was a final presentation from the schools themselves with presentations relating to transport, flooding, and housing. An example of the work related to transport is this video/song from Killermont Primary School [opens in a new window].
Local Priorities and Challenges
Our priority in the coming year is to ensure the smooth running of our monitoring network to gain as accurate a picture as possible of air quality levels across East Dunbartonshire.
We intend to revoke the Bearsden AQMA Order although we will continue to monitor and move forward with any outstanding and ongoing actions in the Bearsden Air Quality Action Plan. Complaints concerning smoke and smell associated with wood burning stoves remain a challenge and have possibly been exacerbated due to people being at home and being more aware of what is going on in their neighbourhood. There has also been an increase in the number of complaints concerning bonfires,chimineas, fire pits and BBQs.

Local Air Quality Management
This report provides an overview of air quality in East Dunbartonshire Council during 2021. It fulfils the requirements of Local Air Quality Management (LAQM) as set out in Part IV of the Environment Act (1995) and the relevant Policy and Technical Guidance documents.
The LAQM process places an obligation on all local authorities to regularly review and assess air quality in their areas, and to determine whether or not the air quality objectives are likely to be achieved. Where an exceedance is considered likely the local authority must declare an Air Quality Management Area (AQMA) and prepare an Air Quality Action Plan (AQAP) setting out the measures it intends to put in place in pursuit of the objectives. This Annual Progress Report (APR) is summarises the work being undertaken by East Dunbartonshire Council to improve air quality and any progress that has been made.

Actions to improve Air Quality
Air Quality Management Areas
Air Quality Management Areas (AQMAs) are declared when there is an exceedance or likely exceedance of an air quality objective. After declaration, the authority must prepare an Air Quality Action Plan (AQAP) within 12 months, setting out measures it intends to put in place in pursuit of the objectives.
A summary of AQMAs declared by East Dunbartonshire Council can be found in Table 2.1. Further information related to declared or revoked AQMAs, including maps of AQMA boundaries are available online at the DEFRA AQMA webpage [opens in a new window].
We propose to revoke the Bearsden AQMA (see monitoring section).

Cleaner Air for Scotland 2
Cleaner Air for Scotland 2 – Towards a Better Place for Everyone (CAFS2] [opens in a new window] is Scotland’s second air quality strategy. CAFS2 sets out how the Scottish Government and its partner organisations propose to further reduce air pollution to protect human health and fulfil Scotland’s legal responsibilities over the period 2021 – 2026. CAFS2 was published in July 2021 and replaces Cleaner Air for Scotland – The Road to a Healthier Future (CAFS) [opens in a new window], which was published in 2015. CAFS2 aims to achieve the ambitious vision for Scotland "to have the best air quality in Europe". A series of actions across a range of policy areas are outlined, a summary of which is available on the Scottish Government’s website.
Progress by East Dunbartonshire Council against relevant actions for which local authorities are the lead delivery bodies within this strategy is demonstrated below
Placemaking - Plans and Policies
Local authorities with support from the Scottish Government will assess how effectively air quality is embedded in plans, policies, City Deals and other initiatives, and more generally in cross departmental working, identifying and addressing evidence, skills, awareness and operational gaps.
Air quality is embedded in the Local Development Plan with specific policy on addressing air quality through planning applications and accompanying Air Quality Planning Guidance. The Strategic Environmental Assessment (SEA) process also includes the assessment of impact on air quality. SEA Officers assess every Council plan and policy and air quality impact assessment is part of the process.
Transport - Low Emission Zones
Local authorities working with Transport Scotland and SEPA will look at opportunities to promote zero-carbon city centres within the existing LEZs structure.
East Dunbartonshire Council has decided to take no further action at this stage on introducing Low Emission Zones as there are currently no exceedences of any of the air quality objectives across the East Dunbartonshire area. The Council does intend introducing a Climate Action Plan with a net zero target for the East Dunbartonshire area and, as transport is one of the main sources of emissions, this will be a key area of focus for carbon reduction.
Progress and impacts of measures to address Air Quality in East Dunbartonshire
East Dunbartonshire Council has taken forward a number of measures during the current reporting year of 2021 in pursuit of improving local air quality. Details of all measures completed, in progress or planned are set out in
Table 2.2. More detail on these measures can be found in the air quality Action Plan relating to each AQMA. Key completed measures are shown in the table.
Progress on the following measures has been slower than expected due to the pandemic and the cancellation of a number of planned projects such as the Air Quality/Active Travel in Schools Project. This measure is currently in the process of going back out to tender.
East Dunbartonshire Council expects this measure to be completed over the course of the next reporting year.

Air Quality Monitoring Data and Comparison with Air Quality Objectives
Summary of Monitoring undertaken
Automatic monitoring sites
This section sets out what monitoring has taken place and how local concentrations of the main air pollutants compare with the objectives.
East Dunbartonshire Council undertook automatic (continuous) monitoring at four sites during 2021. Table A.1 in Appendix A shows the details of the sites. National monitoring results are available at Air Quality in Scotland [opens in a new window].
The annual mean ranged from 16 – 24 µg/m3 across East Dunbartonshire demonstrating compliance with the 40 µg/m3 air quality objective.
Further details on how the monitors are calibrated and how the data has been adjusted are included in Appendix C.
Maps showing the location of the monitoring sites are provided in Appendix D.
Non Automatic monitoring sites
East Dunbartonshire Council undertook non- automatic (passive) monitoring of NO2 at 48 sites during 2021. The diffusion tubes were analysed by Glasgow Scientific Services (GSS), which is a UKAS accredited laboratory, and the data from these tubes was compared against the annual average objective for NO2. Table A.2 in Appendix A shows the details of the sites.
Further details on Quality Assurance/Quality Control (QA/QC) and bias adjustment for the diffusion tubes are included in Appendix C.
Maps showing the location of the monitoring sites are provided in Appendix D.
Other monitoring activities
East Dunbartonshire Council installed two Zephyr mobile monitoring units in the area in February 2020, just prior to the first lockdown. One was installed outside a local primary school in order to utilise the data as part of a school educational programme. To date, neither of these units has been utilised and consideration needs to be given as to whether there is a worthwhile purpose in their installation.
Individual Pollutants
The air quality monitoring results presented in this section are, where relevant, adjusted for annualisation and bias. Further details on adjustments are provided in Appendix C.
Nitrogen Dioxide (NO2)
Table A.3 in Appendix A compares the ratified and adjusted monitored NO2 annual mean concentrations for the past five years with the air quality objective of 40 µg/m3.
For diffusion tubes, the full 2021 dataset of monthly mean values is provided in Appendix B.
Table A.4 in Appendix A compares the ratified continuous monitored NO2 hourly mean concentrations for the past five years with the air quality objective of 200µg/m3, not to be exceeded more than 18 times per year.
There were no exceedences of the air quality objectives for this pollutant within East Dunbartonshire during the calendar year of 2021.
Particulate Matter (PM10)
Table A.5 in Appendix A compares the ratified and adjusted monitored PM10 annual mean concentrations for the past five years with the air quality objective of 18µg/m3.
Table A.6 in Appendix A compares the ratified continuous monitored PM10 daily mean concentrations for the past five years with the air quality objective of 50µg/m3, not to be exceeded more than seven times per year.
There were no exceedences of the air quality objectives for this pollutant within East Dunbartonshire during the calendar year of 2021.
Particulate Matter (PM2.5)
Table A.7 in Appendix A compares the ratified and adjusted monitored PM2.5 annual mean concentrations for the past five years with the air quality objective of 10µg/m3.
There were no exceedences of the air quality objectives for this pollutant within East Dunbartonshire during the calendar year of 2021.
Sulphur Dioxide (SO2)
East Dunbartonshire Council does not monitor sulphur dioxide.
Carbon Monoxide, Lead and 1,3-Butadiene
East Dunbartonshire Council does not monitor carbon monoxide, lead or 1,3 Butadiene.
New Local Developments
Proposed new local developments in East Dunbartonshire which may affect air quality are still subject to obtaining planning permission therefore have been detailed under Planning Applications. Several applications required air quality assessments and are under consideration and these have also been detailed under Planning Applications.
Road traffic sources
East Dunbartonshire Council Roads have reported as follows:
- Narrow congested streets with residential properties close to the kerb – no new roads that meet this criteria
- Busy streets where people may spend one hour or closer to traffic – no new roads that meet this criteria
- Roads with a high flow of buses and/or HGVs – no new roads that meet this criteria
- Junctions new junction to Allander Leisure Centre and housing has signals and a parking ban around it. Should improve traffic flow and so reduce pollution.
- New roads constructed or proposed – Proposed redesign of Canniesburn Toll programmed from October onwards. This will put signals on the Toll and should be better able to regulate traffic flow. It will also improve walking and cycling across/around the Toll
- Roads with significantly changed traffic flow – Roads with significantly changed traffic flows. Most roads had a dip in traffic last year (2021) and have risen towards normal levels this year (2022) however, traffic on Switchback towards Glasgow shown as down from average 11,000 to 8,000 vehicle per day. Also Milngavie Road down from 8,000 to 4,000 in both directions. Likely many who use these roads to Glasgow are able to work from home.
- Bus or coach stations – no new bus or coach stations to report.
The following was also reported:
New or adopted roads:
Cyprian Drive Lenzie
Rutherford Rd Lenzie
Crammond Drive Lenzie
Saltmarsh Drive Lenzie
Carresbrook Place Lenzie
Lumloch Drive Bishopbriggs
Westerhill Drive Bishopbriggs
All of the above are new roads within residential areas.
Other Transport sources
East Dunbartonshire Council confirms that there are no other transport sources as prescribed in the criteria viz: airports; locations where diesel or steam trains are regularly stationary for periods of 15 minutes or more, with potential for relevant exposure within 15m; locations with many movements of diesel locomotives, and potential long-term relevant exposure within 30m or ports for shipping.
Industrial sources
East Dunbartonshire Council confirms that to our knowledge, there are no new industrial sources as prescribed in the criteria viz: new or proposed installations for which an air quality assessment has been carried out or existing installations where emissions have increased substantially or new relevant exposure has been introduced or new or significantly changed installations with no previous air quality assessment; major fuel storage depots storing petrol; petrol stations or poultry farms.
Commercial and domestic sources
East Dunbartonshire Council confirms that to our knowledge, no new commercial or domestic sources have been identified during 2021 which may impact on air quality.
New Developments with Fugitive or Uncontrolled Sources
East Dunbartonshire Council confirms that no new developments with Fugitive or Uncontrolled Sources were identified during 2021.
A planning application for the proposed extraction of hard rock and inert waste landfill from a former colliery has not yet been decided however, the Air Quality Impact Assessment has been approved.
Planning Applications
East Dunbartonshire Council requests a full air quality impact assessment in line with our Planning Guidance and where we consider the application may affect air quality.
All East Dunbartonshire Council projects requiring planning permission come with a full air quality impact assessment as standard.
Environmental Health is consulted on many planning applications and the following included requests for full air quality impact assessments:
1. TP/ED/21/0365 | Residential Development, including associated infrastructure and landscaping on land off Market Road, Kirkintilloch | Site At Fauldhead Old Duntiblae Road Kirkintilloch East Dunbartonshire
An AQIA was requested on the basis that development would lead to 500 or more vehicle movements per day. The report concluded that there would be no significant impact on existing receptors.
2. TP/ED/21/0366 | Residential Development, including associated infrastructure and landscaping on the land off Chryston Road, Kirkintilloch. | Land At Chryston Road Kirkintilloch East Dunbartonshire
This application was raised in conjunction with the above application (0365) and dealt with as one. Conclusion as above.
3. TP/ED/21/0465 | Proposed erection of a Class 1 retail foodstore with associated car parking, access, landscaping and other works. | Land Adjacent To Initiative Road Woodilee Road Lenzie East Dunbartonshire
An AQIA was requested on the basis that development would lead to 500 or more vehicle movements per day. The report concluded that the site would be low risk during the construction phase with an insignificant impact for the operational phase. Mitigation measures in the form of a dust management plan were also submitted.
All of the above applications are still under consideration.
Conclusions and Proposed Actions
Conclusions from new monitoring data
Both automatic and passive monitoring for NO2 carried out during 2021 did not reveal any exceedences of the annual mean Air Quality Objective at any of the monitoring locations within East Dunbartonshire. There has been an overall downward trend across Scotland over the last few years and this trend continued on the whole for all pollutants. The annual mean NO2 level at three of our four automatic monitoring sites rose slightly post pandemic to levels between 16 and 24 µg/m3 as opposed to the objective level of 40µg/m3 however, the level at our Bishopbriggs site dropped from 20 µg/m3 in 2020 to 18.6µg/m3 (16.8µg/m3 after annualisation) for 2021.No exceedences of the hourly mean were recorded.
Similarly, PM10 levels at three out of four of our automatic monitoring sites recorded slight increases varying between 9.5 µg/m3 at Bearsden and 10.7 µg/m3 at Kirkintilloch however, the level at our Milngavie site dropped from 10 µg/m3 in 2020 to 8.7 µg/m3 in 2021; all well below the annual mean objective level of 18µg/m3.
PM2.5 was measured at all four automatic monitoring sites and again, rose slightly at three out of four of our monitoring sites however, the level reduced slightly at our Bishopbriggs site dropping from 6 µg/m3 in 2020 to 5.9 µg/m3 in 2021.
East Dunbartonshire Council has two Air Quality Management Areas – Bishopbriggs and Bearsden. All monitoring results within the AQMAs are below the air quality objective levels for which they were declared and have been for some time. Committee approval to revoke the Bearsden AQMA was forthcoming in November 2021 and approval from both the Scottish Government and Sepa has been confirmed. It is not our intention to revoke the Bishopbriggs AQMA just yet due to the number of planned infrastructure and development changes planned as part of the City Deal funding award.
Conclusions relating to new local developments
East Dunbartonshire Council has no exceedences of any of the relevant air quality objectives and new local developments are unlikely to introduce new exceedences. Although a number of applications for development have included air quality impact assessments, there is nothing to indicate that such development would introduce any new exceedences of any of the air quality objectives.
Proposed actions
Monitoring data for 2021 has not identified any new exceedences of the objectives for any pollutant and all monitored areas of East Dunbartonshire are not only in compliance but are well below the objective levels, even although traffic levels have gradually returned to pre pandemic levels.
A review of the NO2 tube network has seen the removal of a number of NO2 tubes which confirm there is no longer any need for concern in the particular area in terms of air quality objective levels.
The revocation of the Bearsden AQMA has been approved by committee and agreed with the Scottish Government and Sepa. The Revocation Order is due to be signed imminently at which time further consultation and relevant publicity will be undertaken.
It is not our intention to revoke the Bishopbriggs AQMA at this stage due to the extensive proposed redevelopment of Bishopbriggs in line with City Deal funding including an aspiration to complete phase 5 of the Bishopbriggs Relief Road (now referred to as Westerhill Development Road). It is anticipated that during construction over several years, local air quality data may be unreliable.
We will continue to implement Action Plan measures where funding allows.
The next Annual Progress Report will be submitted in 2023.

New or Changed Sources Identified Within East Dunbartonshire Council During 2021
East Dunbartonshire Council has not identified any new sources relating to air quality within the reporting year of 2021.
Additional Air Quality Works Undertaken by East Dunbartonshire Council During 2021
East Dunbartonshire Council has not completed any additional works within the reporting year of 2021.
QA/QC of Diffusion tube monitoring
The diffusion tubes are supplied and analysed by Glasgow Scientific Services (GSS) and are prepared using the 20% TEA in water method and in accordance with the procedures set out in the practical guidance. Glasgow Scientific Services (GSS) Laboratory is UKAS accredited for the analysis of Diffusion tubes. The duration of exposure is normally the 4/5 week period as suggested by the calendar provided by Defra. All results have been bias adjusted and annualised where required.
Glasgow Scientific Services (GSS) Laboratory also participates in the independent AIR-PT scheme for NO2 tubes analysis and GSS has performed to the following proficiency levels during the AIR-PT testing scheme in 2021.
January-February - 50%
May-June – 100%
July-August – 100%
September-October – no report
The above results were determined to be satisfactory based upon a z-score of £ ± 2.
Diffusion tube annualisation
All diffusion tube monitoring locations within East Dunbartonshire recorded data capture of 75% therefore it was not required to annualise any monitoring data. In addition, any sites with a data capture below 25% do not require annualisation.
Diffusion Tube Bias Adjustment Factors
East Dunbartonshire Council have applied a local bias adjustment factor of 0.97 to the 2021 monitoring data. A summary of bias adjustment factors used by East Dunbartonshire Council over the past five years is presented in Table C.1.
The local bias adjustment factor of 0.97 was derived from four co-location studies undertaken at Bishopbriggs, Bearsden, Kirkintilloch and Milngavie.

NO2 Fall-off with Distance from the Road
No diffusion tube NO2 monitoring locations within East Dunbartonshire required distance correction during 2021 therefore Table C.4 has been removed.
QA/QC of Automatic Monitoring
All automatic sites are part of the Scottish Air Quality Programme and are audited twice per year by Ricardo. Servicing and repair is carried out by Acoem UK and Horiba UK, the service contracts include a six monthly service of instruments, call outs to site for repairs and the routine replacement of consumables. All data is available in real-time, and regularly scaled and ratified by Ricardo on behalf of the Scottish Government.
PM10 and PM2.5 monitoring adjustment
The type of PM10/PM2.5 monitors utilised within East Dunbartonshire Council do not require the application of a correction factor.
Automatic Monitoring Annualisation
All automatic monitoring locations within East Dunbartonshire Council recorded data capture of greater than 75% apart from Bishopbriggs which recorded 56.7% for NO2 and has therefore required annualisation.
NO2 fall-off with distance from the road
No automatic NO2 monitoring locations within East Dunbartonshire Council required distance correction during 2021.
Table C.2 - Annualisation Summary (concentrations presented in µg/m3)
There is no LAQM annualisation tool to process annualisation for automatic monitoring, therefore guidance as per Chapter 7: NOx and NO2 Monitoring of the LAQM Technical Guidance 2016 has been followed and the results presented within Table C.2
