Executive Summary: Air Quality in Our Area Air Quality in Leeds City Council Air pollution is associated with a number of adverse health impacts. It is recognised
as a contributing factor in the onset of heart disease and cancer. Additionally, air
pollution particularly affects the most vulnerable in society: children and older people,
and those with heart and lung conditions. There is also often a strong correlation with
equalities issues, because areas with poor air quality are also often the less affluent
areas1,2.
The annual health cost to society of the impacts of particulate matter alone in the UK
is estimated to be around £16 billion3.
Air quality monitoring in Leeds shows that air quality in the majority of the city, it’s
suburbs and rural areas achieve UK and EU objectives.
The main pollutants of concern within Leeds are Nitrogen Dioxide (NO2) and
particulate matter. The main source of nitrogen dioxide in Leeds is from vehicle
emissions. The principal source of particulate matter is road traffic emissions,
particularly from diesel vehicles. It is also emitted from industrial combustion plants
and public power generation, commercial and residential combustion, and some non-
combustion processes (e.g. quarrying). Natural sources can include airborne dust
and sea salt from vast distances away.
Long term trends show an ongoing improvement in air quality but there are areas in
Leeds that remain above the annual mean air quality objective for NO2. Monitored
levels of particulate matter, both PM10 and PM2.5 are well within UK and EU
objectives and are close to World Health Organisation guideline levels.
Leeds has six Air Quality Management Areas (AQMA’s) in response to exceedances
in NO2 objectives. Monitoring at the AQMA’s shows a generally reducing trend in
pollution with levels in 2018 now compliant with the annual average objective in four
of our AQMA’s. In addition a number of city centre locations, not declared as
AQMA’s, have shown exceedances of the annual average for NO2. The

implementation of the Clean Air Charging Zone in 2020 and traffic management
proposals are expected to address these concerns.
The current AQMA’s are shown in Appendix D and can also be viewed online at
https://uk-air.defra.gov.uk/aqma/details?aqma_ref=665
Real time monitoring is undertaken at eleven sites across Leeds. This allows hourly
and daily air quality objectives to be assessed as well as annual objectives.
Permitted exceedances for the hourly average objective for NO2 and the daily
average objective for PM10 were not breached during 2018 at any of our monitoring
sites.
Following ministerial approval Leeds is on course to introduce a Clean Air Charging
Zone (CAZ) in 2020. The CAZ, one of the largest of its kind in the country, will reduce
air pollution in Leeds by encouraging businesses to transition to cleaner, less
polluting vehicles. Further details of CAZ can be found at
www.leeds.gov.uk/cleanairzone
Actions to Improve Air Quality Leeds City Council is committed to improving air quality in the city and has
undertaken a vast array of work to this end, with a particular focus on targeting
nitrogen dioxide emissions associated with road transport. The CAZ is the most
pivotal piece of this broad programme of work. Due to go live in 2020, the CAZ has
been modelled to deliver significant air quality improvements across the city,
incentivising affected sectors to upgrade their vehicles to cleaner, less polluting,
compliant vehicles that will not be charged to enter the zone.
The Council and the West Yorkshire Combined Authority (WYCA) have secured
almost £2 million from the government’s Office for Low Emission Vehicles (OLEV) for
the installation of 88 new, free electric vehicles rapid charge points (EVCPs) across
West Yorkshire. 30 of these charge points will be in Leeds as the council continues to
work toward a hub model of strategically placed EVCPs across the city. Using
planning conditions, the council will also ensure that new developments include
provision for EVCPs.
Improving the cycling and walking infrastructure in Leeds also remains a top priority
and a significant amount of work has been delivered so far. The Cycle Superhighway
Leeds City Council
LAQM Annual Status Report 2019 iii
connecting Leeds and Bradford, upgrades to the Leeds Liverpool Canal towpath, and
the Leeds City Centre Cycle Superhighway have all been completed.
A table detailing measures to improve air quality across the city can be found at
Table 2.2 within the main body of the report.
Conclusions and Priorities As was the case in last year’s Annual Status Report, reducing pollutant
concentrations continues to be the common trend in Leeds. Four of our AQMA’s are
now indicating results below objective levels and can be considered for revocation in
the near future.
The Clean Air Charging Zone is a hugely significant piece of work that will see a step
change in the emission standards of vehicles driving in the city.
Further schemes will improve access to cycling routes whilst public transport is of
course a key focus. On street car parking provision in the city centre continues to
decrease whilst the popularity of the city’s park and ride sites increases, removing
thousands of cars from the city centre each week.
Local Engagement and How to get Involved Clean Air Leeds is the platform for Leeds’ air quality behaviour change campaign.
The campaign is aimed at three key audiences: residents, schools and organisations.
Its objective is to raise awareness of the things these groups can do to improve the
quality of air we breathe. Reducing air pollution will require a city-wide effort, and
even small anticipated changes in behaviour will have a significant positive impact on
air quality.
The campaign has built a following on social media, and was ‘launched’ alongside
the National Clean Air Day campaign in June 2017. Since its launch there has been
engagement with schools through competitions, encouraging children to walk, cycle
or ‘park & stride’ to school, and we have developed toolkits with activity packs that
can be used by teachers. We have been providing businesses with one-to-one
briefings to discuss how they can reduce air pollution or emissions through their fleet,
supply chain, staff travel and heating. Residents are regularly communicated with
through the Clean Air Leeds inbox, through which the council provides advice on the
Leeds City Council
LAQM Annual Status Report 2019 iv
Clean Air Charging Zone, electric vehicle charge points, idling, and air quality issues
(advising on both citywide and localised trends).
The Clean Air Leeds website has had an extensive amount of content added over the
course of the previous 12 months. Individual pages now advise each of the three
target audiences (residents, schools, organisations) on what they can do to reduce
their carbon footprint and subsequently their contribution to air pollution.
This year, much of the focus of the Clean Air Leeds campaign has been on engine
idling. There has been a citywide communications campaign to spread awareness of
the issue, and anti-idling road signs are to be installed outside a number of Leeds
schools and all city centre taxi ranks. Over two hundred schools so far have also
received free anti-idling banners, to encourage those dropping children off or picking
them up at the end of the school day, to switch off their engines and reduce their
emissions.
Further information on the campaign and the council’s progress to date can be found
at www.CleanAirLeeds.co.uk or connect with the team on social media via

LAQM Annual Status Report 2019 1
1 Local Air Quality Management This report provides an overview of air quality in Leeds City Council during 2018. 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 Status Report (ASR) is an annual
requirement showing the strategies employed by Leeds City Council to improve air
quality and any progress that has been made.
The statutory air quality objectives applicable to LAQM in England can be found in
Table E.1 in Appendix E.
Leeds City Council
LAQM Annual Status Report 2019 2
2 Actions to Improve Air Quality 2.1 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 12-18 months setting out measures
it intends to put in place in pursuit of compliance with the objectives.
A summary of AQMAs declared by Leeds City 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, https://uk-air.defra.gov.uk/aqma/local-
authorities?la_id=143 Alternatively see Appendix D: Maps of Monitoring Locations

2.2 Progress and Impact of Measures to address Air Quality in Leeds City Council
Defra’s appraisal of last year’s ASR concluded that the report was well structured, and
provided all the information required by the DEFRA Guidance.
Specific points raised by the appraisal are set out below with the updated response
from Leeds City Council:
1. The 2018 report highlighted the ongoing work that is taking place, with regard
to the development of the CAZ. Response: Development of the CAZ continues
as a priority with implementation expected in 2020.
2. The development of a full set of action plan measures will need to follow on
from, and be designed to complement the Caz in order to be effective.
Response: A comprehensive set of complimentary measures are in place (see
Table 2.2).
3. Monitoring results at 3 of the 6 AQMA’s are below objective levels. It is
recommended that monitoring continues at all sites for the time being.
Response: Monitoring has continued at all 6 AQMA sites in 2018.
4. Results in Table B1 suggest there are only 5 diffusion tube sites with
exceedances representative of relevant exposure (DT’s 59,105,114,121,165).
However none of these sites are located within an AQMA, highlighting there
may be significant uncertainty in the boundary of the current AQMA’s.
Response: DT’s 59, 121 and 165 are located within the proposed CAZ and it is
expected that the implementation of the CAZ will address these exceedances.
DT105 is located in a position of limited relevant exposure characteristics.
DT114 is located within the Pool in Wharfedale AQMA.
5. Four automatic monitoring sites (A2,A6,A21,A22) have exceedances
representative of relevant exposure. Notable site A22 in City Square is
exhibiting results above 60 μg/m3 and requires further investigation in order to
determine the extent of potential exceedances of the hourly mean objective.
Sites A2, A21,A22 are not located within AQMA’s. Response: A2, A6, A21, A22
monitoring sites are located within the proposed CAZ and it is expected that the
implementation of the CAZ and associated traffic management measures to City
Leeds City Council
LAQM Annual Status Report 2019 7
Square will address these exceedances. Further investigation of NO2 hourly
mean levels at A22 identified there were no exceedances of the hourly limit in
2018.
Leeds City Council has taken forward a number of direct measures during the current
reporting year of 2018 in pursuit of improving local air quality. Details of all measures
completed, in progress or planned are set out in Table 2.2.
Leeds City Council expects the following measures to be completed over the course
of the next reporting year:
1. Implementation of a Clean Air Charging Zone.
2. Delivery of funding packages to support HGV, bus, coach, taxi and private hire
operators to replace or upgrade their vehicles to be CAZ compliant.
3. Continued replacement of existing Council Fleet vehicles with ULEV’s.
4. Expansion of the anti-idling campaign with a particular focus on schools.
5. Roll out of electric vehicle rapid charging points across the city.
Leeds City Council anticipates that the implementation of a CAZ and the measures
stated in Table 2.2 will support compliance in the Normans AQMA.
Burley in Wharfedale AQMA is outside of the CAZ boundary and whilst air quality is
improving and there is likely to be further improvements linked to the CAZ and other
measures in place across the city it is recognised that further measures specific to the
AQMA may be required to ensure compliance. To this end ANPR data for the AQMA
has been used to understand the likely contributions of vehicle types and age to
emission source apportionment. Portable real time analysers have been installed to
identify concentrations of pollutants at specific times of the day. This information may
then be used to inform any microsimulation and instantaneous emission modelling to
determine whether it is possible to improve the situation through traffic management
methods.

Note:
(a) In relation to the ‘Reduction in Pollutant/Emission from Measure’ column, all are intended to have a positive benefit in the Council’s efforts to tackle traffic emissions
across the whole of the city, reducing the highest pollution levels where they occur and reducing background concentrations elsewhere.

2.3 PM2.5 – Local Authority Approach to Reducing Emissions and/or Concentrations
As detailed in Policy Guidance LAQM.PG16 (Chapter 7), local authorities are
expected to work towards reducing emissions and/or concentrations of PM2.5
(particulate matter with an aerodynamic diameter of 2.5µm or less). There is clear
evidence that PM2.5 has a significant impact on human health, including premature
mortality, allergic reactions, and cardiovascular diseases.
Leeds City Council is taking the following measures to address PM2.5:
There are a number of sources of PM2.5 particles, many of which relate to traffic and
transportation. Tailpipe emissions from diesel vehicles have been identified as a
major source in the past but others, including brake, clutch and tyre wear all
contribute to the overall burden as well as re-suspension from the road surface in the
wake of a moving vehicle.
Although tyre wear and re-suspension will prove difficult to tackle, hybrid and full
electric vehicles deliver reduced emissions from tailpipes and clutch use while also
benefiting from regenerative braking systems.
A number of the measures described in Table 2.2 above seek to reduce the more
polluting vehicle types, while increasing the proportion of ULEVs, the use of Park &
Ride sites and car clubs esp. with ULEVs.
Particulate pollution from domestic sources is recognised an emerging issue in Leeds
as it is across the country. Most areas of Leeds are designated as Smoke Control
Areas. Advice and enforcement protocols are in place within the Council’s Cleaner
Neighbourhood Teams to take the appropriate action in cases of non compliance
with Smoke Control and Environmental Protection legislation.
Demolition and construction dust is controlled by planning conditions requiring
demolition and construction management plans.
All measures outlined in Table 2.2 that aim to reduce NO2 and PM10 will also have a
beneficial impact on PM2.5.
Measures to reduce and control PM2.5 emissions will continue although it is noted
that both AURN monitoring sites in Leeds (Leeds Centre and Headingley kerbside)
that measure PM2.5 recorded annual mean concentrations of 12 µg m-3 and
Leeds City Council
LAQM Annual Status Report 2019 18
11 µg m-3 respectively in 2018. Both within air quality objectives and close to the
World Health Organisation Guideline of 10 µg m-3.
Leeds City Council
LAQM Annual Status Report 2019 19
3 Air Quality Monitoring Data and Comparison with Air Quality Objectives and National Compliance 3.1 Summary of Monitoring Undertaken The data capture target of 85% was attained at nine of the eleven automatic monitors
located in Leeds. Two sites failed to meet the target due to technical issues. Actions
are in place to ensure capture targets are met at all sites going forward.
Additional diffusion tube sites were included in the 2018 monitoring programme to
support a range of projects including the Local Public Transport Infrastructure
Programme (LPTIP), the East Leeds Orbital Route (ELOR) and further baseline
measurements prior to the CAZ implementation and planned city centre
transport/public realm improvements.
A number of diffusion tube monitoring sites were removed in 2018 on the completion
of short term projects looking at local air quality following Ward Member and resident
queries. All sites showed compliance and were not of concern.
No changes to the AQMA’s are proposed.
3.1.1 Automatic Monitoring Sites
This section sets out what monitoring has taken place and how it compares with
objectives.
Leeds City Council undertook automatic (continuous) monitoring at 11 sites during
2018. Nine of the sites were operated exclusively by the city council while one is part
of the Automatic Urban and Rural Network (AURN) and the other an affiliated site
owned by the city council but with results accepted into the national network.
Table A.1 in Appendix A shows the details of the sites. National monitoring results
are available at https://uk-air.defra.gov.uk/imnteractive-map where a full data set from
the Leeds Centre site is available (monitoring includes NOx/NO2, PM10, PM2.5, SO2,
CO, O3 and benzene). Full data from the Headingley Kerbside site (NOx/NO2, PM10
and PM2.5) is also available on this site. In 2018 the council maintained its own TEOM
Leeds City Council
LAQM Annual Status Report 2019 20
at the Corn Exchange site to monitor PM10 and VCM adjusted results are available in
Tables A.5 and A.6.
Maps showing the location of the monitoring sites are provided in Appendix D.
Further details on how the monitors are calibrated and how the data has been
adjusted are included in Appendix C.
3.1.2 Non-Automatic Monitoring Sites
Leeds City Council undertook non-automatic (passive) monitoring of NO2 at 282 sites
during 2018. Table A.2 in Appendix A shows the details of the sites.
Maps showing the location of the monitoring sites are provided in Appendix D.
Further details on Quality Assurance/Quality Control (QA/QC) for the diffusion tubes,
including bias adjustments and any other adjustments applied (e.g. “annualisation”
and/or distance correction), are included in Appendix C.
3.2 Individual Pollutants The air quality monitoring results presented in this section are, where relevant,
adjusted for bias, “annualisation” and distance correction. Further details on
adjustments are provided in Appendix C.
3.2.1 Nitrogen Dioxide (NO2)
Table A.3 in Appendix A compares the ratified and adjusted monitored NO2 annual
mean concentrations for the past 5 years with the air quality objective of 40µg/m3.
For diffusion tubes, the full 2018 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 5 years with the air quality objective of 200µg/m3,
not to be exceeded more than 18 times per year.
The Jack Lane automatic monitoring site (A9) recorded one hour exceeding the 200
µg m-3 objective in 2018.
Leeds City Council
LAQM Annual Status Report 2019 21
The following diffusion tubes recorded annual averages above 60 µg m-3,
DT 181 City Square/Boar Lane 61 µg m-3
DT183 Neville Street NW tunnel exit 88 µg m-3
DT 184 Neville Street NE tunnel entrance 65 µg m-3
DT 403 Bishopgate Street road side 60 µg m-3
To further investigate the potential for exceedances of the NO2 hourly mean
concentration objective of 200 µg m-3 the Bishopgate Street automatic monitoring
site (A21) was established as close as reasonably practicable to the elevated results
obtained on the north side of the Neville street tunnel with the rail station platforms
and station approach above. There were no exceedances of the 200 µg m-3
objective during 2018.
A number of diffusion tubes were introduced in 2018 to support the LPTIP and other
infrastructure improvements. Whilst a number of the locations recorded annual
averages above 40 µg m-3 these locations were not relevant to long term exposure
characteristics. However all these locations are within the CAZ boundary and will
benefit from its implementation.
D377 recorded an annual average of 46 µg m-3 and is relevant to long term
exposure. Again this location is within the CAZ boundary and will benefit from its
implementation. Additional diffusion tubes have been located around the vicinity in
2019 to better understand the localised air quality.
3.2.2 Particulate Matter (PM10)
Table A.5 in Appendix A compares the ratified and adjusted monitored PM10 annual
mean concentrations for the past 5 years with the air quality objective of 40µg/m3.
Table A.6 in Appendix A compares the ratified continuous monitored PM10 daily
mean concentrations for the past 5 years with the air quality objective of 50µg/m3, not
to be exceeded more than 35 times per year.
There have been no exceedances of these objectives for several years.
3.2.3 Particulate Matter (PM2.5)
Table A.7 in Appendix A presents the ratified and adjusted monitored PM2.5 annual
mean concentrations for the past 5 years.
Leeds City Council
LAQM Annual Status Report 2019 22
Annual mean concentrations monitored in Leeds in 2018 were well within the
objective.
3.2.4 Sulphur Dioxide (SO2)
Table A.8 in Appendix A compares the ratified continuous monitored SO2
concentrations for 2018 with the air quality objectives for SO2.
Although air quality issues around SO2 were confidently dismissed more than ten
years ago, monitoring of this pollutant continues at the Leeds Centre site to inform
the national network. There have been no breaches of any of the objectives applying
to this pollutant.

☒ Diffusion tube data has been bias corrected ☒ Annualisation has been conducted where data capture is <75% Notes: Exceedances of the NO2 annual mean objective of 40µg/m3 are shown in bold. NO2 annual means exceeding 60µg/m3, indicating a potential exceedance of the NO2 1-hour mean objective are shown in bold and underlined. (1) Data capture for the monitoring period, in cases where monitoring was only carried out for part of the year. (2) Data capture for the full calendar year (e.g. if monitoring was carried out for 6 months, the maximum data capture for the full calendar year is 50%). (3) Means for diffusion tubes have been corrected for bias. All means have been “annualised” as per Boxes 7.9 and 7.10 in LAQM.TG16 if valid data capture for the full calendar year is less than 75%. See Appendix C for details.

LAQM Annual Status Report 2019 101
Appendix C: Supporting Technical Information / Air Quality Monitoring Data QA/QC C.1 QA/QC of Automatic monitoring network and data
The Leeds City Council monitoring network is managed and operated by a team of
officers within the Environmental Protection Team (EP Team) of the Communities
and Environment Directorate. The combined expertise of this group covers all
aspects of the management of the network from routine site procedures through
calibration to data ratification. Appropriate training both internal and from external
agencies such as EMAQ has been received by officers within the team.
The QA/QC for the Leeds Centre AURN site and the affiliated Leeds Headingley
Roadside site is carried out by Ricardo Energy & Environment (E&E). Officers within
the EP Team provided LSO support for the Leeds Centre site between 1993 and
2009 and continue in the LSO role at the Headingley site.
C.1.1 Instrumentation
In 2018 a combination of API and Monitor Labs instruments were used to monitor
oxides of nitrogen (NOx) to establish NO2 concentrations in the network together with
an R&P TEOM to monitor PM10 particles at the Corn Exchange site in the city centre.
All stations are air conditioned with the exception of Temple Newsam where the
analyser is sited in a large brick-built store room/unused office.
C.1.2 Servicing
Service contracts are in place so that all analysers are serviced every 6 months
together with 6 monthly GPT testing of the gas analyser at the Headingley site and
annual GPT testing elsewhere. The contract also requires attendance to
breakdowns within 48 hours of callout.
All service and breakdown visits by engineers are recorded in the form of engineers’
reports and stored within the Department for later use (during data ratification,
assessment of long-term analyser performance etc.).
C.1.3 Calibration
Sites are attended for regular manual calibrations, routine site checks and
maintenance. The procedures for these site visits are documented in internal
Leeds City Council
LAQM Annual Status Report 2019 102
guidance documents based on the instrument manufacturers’ operation manuals and
the AURN Site Operators Manual.
Pre-calibration checks are made which check ancillary equipment such as modems
and air conditioning and to record instrument status.
Zero response to clean air is carried out through the use of in-line scrubbers.
Span checks are carried out using nitric oxide calibration gas of known concentration
with a certified concentration.
Instrument and TEOM filters are changed if required followed by post-zero and span
checks to ensure that everything is operational before leaving site.
All Calibration visits are recorded on calibration forms and on site specific
spreadsheets kept within the Department.
C.1.4 Data collection
Automatic data collection from the stations is achieved using the Airviro data
administration module. 15-minute un-scaled data is collected from the on-board
memory of each analyser.
The data is reviewed daily to determine that the collection protocols are working, that
the data looks sensible and to identify faults. This involves viewing and comparing
data from different locations.
Should assessment of the data lead to action being taken, this is recorded within site
spreadsheets kept by the Department.
C.1.5 Site Audits
In addition to regular calibrations and six monthly servicing of the equipment, an
annual GPT test (when testing is carried out on the equipment with a separate
calibration gas) to confirm the ongoing acceptable performance of the analysers is
carried out.
Site audits of the Headingley and Leeds Centre sites are carried out independently
as part of the AURN national network.
C.1.6 Data ratification
While this process was carried out in-house, in recent years data ratification has
been carried out externally by Air Quality Data Management.
Leeds City Council
LAQM Annual Status Report 2019 103
Electronic analysers suffer drifts in their response to the zero (baseline) gas and
sensitivity changes with time. Raw data from the NOx instruments are therefore
scaled into concentrations using the latest values derived from the manual and
automatic calibrations.
The ratification process finalises the data to produce the measurements suitable for
reporting. All available information (including calibrations results, service records and
audit reports) is critically assessed so that the best data scaling is applied and all
anomalies are appropriately edited. Generally this operates at three, six or twelve
month intervals. However, unexpected faults can be identified during the instrument
routine services or independent audits which are often at 6-monthly intervals. In
practice, therefore, the data can only be fully ratified in 12-month or annual periods.
The data processing performed during the three and six monthly cycles helps build a
reliable dataset that is finalised at the end of the year.
In addition to overcoming the drift in analyser performance, anomalies in the
collected data can occur for a variety of reasons that could result in data being
discarded. Instruments and infrastructure can fail in numerous ways that significantly
and visually affect the quality of the measurements. These may include:
• ignoring calibrations that were poor e.g. a spent zero scrubber
• closely tracking rapid drifts or eliminating the data
• comparing the measurements with other pollutants and nearby sites
• corrections due to span cylinder drift
• corrections due to flow drifts for the particulate instruments
• corrections for ozone instrument sensitivity drifts
• eliminating measurements for NO2 conversion inefficiencies
• eliminating periods where calibration gas is in the ambient dataset
• identifying periods were instruments are warming-up after a powercut
• identification of anomalies due to mains power spikes
• correcting problems with the date and time stamp
• observations made during the sites visits and services
Leeds City Council
LAQM Annual Status Report 2019 104
The identification of data anomalies, the proper understanding of the effects and the
application of appropriate corrections requires expertise gained over many years of
operational experience.
C.1.7 PM10 corrections
Monitoring of PM10 (and PM2.5) as part of the national AURN is carried out using
FDMS (filter dynamics measurement system) equipment. However, the PM10 monitor
installed in the Corn Exchange monitoring station is an older TEOM (Tapered
Element Oscillating Microbalance) instrument. Results from this equipment are
corrected to a ‘gravimetric equivalent’ (ie the FDMS system) using the TEOM VCM
(Volatile Correction Model).
C.2 QA/QC of diffusion tube monitoring
C.2.1 Diffusion tube precision and ‘AIR NO2 PT’ performance
The West Yorkshire Analytical Services laboratory (WYAS) supply nitrogen dioxide
diffusion tubes to the city council for its investigations. AIR NO2 PT is an independent
analytical proficiency-testing scheme run on behalf of Defra. Performance reports on
all analytical laboratories taking part in AIR NO2 PT are described as satisfactory.
The AIR NO2 proficiency testing scheme reported that WYAS achieved the following
percentage of results determined as satisfactory in 2018:
Table C.1
In terms of the precision associated with the analysis of multiple tubes there are no
occasions in the last three years when the performance of WYAS was described as
anything other than ‘Good’.
C.2.2 Diffusion tube bias adjustment factors
The preparation method of the nitrogen dioxide diffusion tubes supplied to the city
council has been 50% TEA in acetone manufactured by Harwell Scientific Services.
A spreadsheet compiled by the National Physical Laboratory reports bias corrections
reflecting the difference between results obtained from automatic analysers

compared with those obtained from co-located diffusion tubes analysed by individual
laboratories. The NPL reported bias correction to be used for this diffusion tube and
WYAS as the analyst is 0.80 for 2018 tube data.
C.2.3 Diffusion tube annualisation
The reported diffusion tube results have been annualised in accordance with TG (16)
where data collection has been less than 75% (and no less than 25%). Data used for
each annualisation of bias corrected diffusion tube results has been the appropriate
periods of the ratified hourly data from the two AURN sites in Leeds used in
conjunction with the annual mean result from those two sites.
C.2.4 NO2 fall-off with distance correction for diffusion tube data
Where it was appropriate to calculate the annual mean NO2 concentration (typically
at the nearest residential property), the LAQM distance correction tool was used.
Data collected in relation to source (ie Kerb) to tube location and source to receiver
was used together with the Defra predicted 2017 background concentration for the
1km x 1km grid square in which the measurement/property was located.
