LAQM Annual Status Report 2019 i

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

https://uk-air.defra.gov.uk/aqma/details?aqma_ref=665

http://www.leeds.gov.uk/cleanairzone

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


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-

☒ Leeds city Council confirm the information on UK-Air regarding their AQMA(s) is up to date Note: (1) Although an Air Quality Action Plan for Leeds as a whole has been in place since 2004 and was informally updated to reflect ongoing proposals to improve air quality, the Action Plan is now complimented by the air quality improvement actions contained within the CAZ proposal and implementation plan.

Leeds City Council


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


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


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


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

https://uk-air.defra.gov.uk/imnteractive-map

Leeds City Council


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


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


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.

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


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


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


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.

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.
