Abstract
"Poor air quality is the largest environmental risk to Public Health in the UK" (DEFRA, 2017) and is consequently a focus of a range of regional and national policy interventions. However, since our transport systems, the way we heat our homes, our energy supply, our use of solvents and our agricultural systems are all changing, we know that profound changes in emissions and trends in air pollutants are likely in the coming years and indeed are already taking place. We need to understand our changing atmospheric composition, to ensure air quality policy has maximum benefit for the protection of human and environmental health.
The Clean Air: Analysis and Solutions Programme identifies the need for new capability to predict future changes in the sources, emissions and atmospheric processes responsible for air pollution. The OSCA project addresses this need through a multidisciplinary research activity, combining state-of-the-science atmospheric observations, laboratory studies, new data processing tools and integrated scientific synthesis to deliver new understanding of urban air pollution. OSCA will:
-Deliver improved quantification of emissions, combining lab measurements of brake & tyre wear sources, and measurements of the total fluxes of particulate matter (PM) and nitrogen dioxide (NO2) from the BT Tower in London. Nonexhaust emissions comprise up to 70% of traffic-derived PM10, are poorly quantified, and whose relative importance will increase with UK fleet decarbonisation. Real-world emission measurements underpin air quality predictions and avoid dependence upon manufacturer data.
-Provide a definitive, state-of-the-science assessment of UK urban air quality through exploitation of the new RCUK-funded urban air quality Supersites in London, Birmingham and Manchester to deliver comprehensive, continuous and long-term measurements of atmospheric composition. These data will characterise the changing UK pollution climate, identify subtle emission trends during implementation of regional air quality policies, and provide a key resource for evaluation of ongoing trends.
-Develop new mathematical analyses to identify emergent trends / responses to policies and apply these alongside established methods to address key science uncertainties - e.g.: to assess the trends and changing sources of NO2; to provide definitive quantification of the contributions of non-exhaust traffic, woodsmoke and cooking activities to PM; to identify trends in and contributions to ammonia emissions; to identify changes VOC emissions - precursors to ozone formation.
-Provide data and infrastructure to underpin the wider Clean Air Programme, including development and deployment of novel sensor networks (QUANT); data to validate models and health effect calculations (InSPIRE and DREaM); insight into air quality response to policy initiatives (ANTICIPATE); sensor testing and pollutant source identification (APEx).
-Enable community mobilisation through intensive field campaigns, targeted at understanding the changing gas-phase reactivity climate of the UK atmosphere (which governs production of secondary PM and ozone), and the sources and chemical composition of atmospheric aerosols.
OSCA findings will support policymakers through a range of established relationships the PIs already maintain. These include engagements within the supersite host cities, and links to relevant national bodies, including Defra, DfT, DoH, PHE and the EA. The OSCA deliverables provide important new data and novel scientific approaches central to the assessment of future changes in the sources, emissions and atmospheric processes governing air pollution in the UK - the core of WP1 of the Clean Air programme. OSCA is fully embedded into the wider programme, informing policy decisions, monitoring the impacts of decisions, and feeding public health research and outcomes.

Planned Impact
OSCA is an underpinning proposal to the UKRI Clean Air Programme and will deliver significant impact through support for multiple projects, whilst also generating wider impacts in its own right. The main direct beneficiaries of the research are the agencies invested in the activities of the programme, national and regional policy makers and public health professionals. Since the Met Office and STFC are delivering the Framework for Clean Air Analysis in WP4 they are clear beneficiaries of the outputs. The key stakeholders at national level are the Department for Environment Food and Rural Affairs; the
Department for Transport; and Public Health England. At regional level key stakeholders are the combined authorities in London; Manchester and Birmingham and Transport for Greater Manchester and Transport for London. PHE Consultants in the regions provide public health advice to regional government.
OSCA project outcomes result from PIs working closely with policy makers at regional and national level to identify key areas of concern. Emissions of NOx are of immediate and direct importance to UK air quality policy and evaluating ongoing changes in emissions has direct policy relevance given the traffic fleet is changing rapidly. Whilst particulate traffic
exhaust emissions are relatively well understood, the quantification of non-exhaust emissions that OSCA will deliver has direct benefit to national and regional policy making as the UK fleet electrifies and conventional exhaust emissions diminish. OSCA will provide policy makers with new information on the contributions to the urban mass burden from sources such as wood burning and cooking which can be used to base future decisions regarding PM control. OSCA will provide new data on urban ammonia and source attribution between agriculture and urban sources and so support policy makers in their prioritisation and strategies for reducing emissions.
Identifying the drivers of trends in pollutant concentrations and attributing changes to specific interventions and policies is extremely challenging, given the large number of confounders that exist. OSCA will develop approaches to tackle this problem, utilising a wide range of data currently available to assess the extent to which such causality can be attributed and will provide a framework for wider modelling work that will investigate this. Such tools will be widely disseminated for other stakeholders to use themselves.
OSCA measurements of the composition of air pollution, along with source attribution, will provide observational constraints to other projects within the Clean Air programme who are forecasting air quality, modelling policy interventions, assessing air quality sensor networks, measurement innovation, assessing exposure and identifying health impacts. The information and expertise from OSCA will therefore inform public health professionals investigating the health impacts of air quality in UK cities.
This work has the potential to generate significant impact with regional authorities in other areas of the UK, through the dissemination of findings, and the translation of tools. The project will seek out aspects of the research that have wider applicability to other cities and work to support decision-making more broadly in the UK.
Lastly, in many cases air quality improvements will not be delivered by policy alone but require public engagement, including technology uptake and behaviour change to deliver cleaner air. The willingness of the public to embrace change is very dependent on their knowledge of the problem, their trust in the solutions and engagement with the change process. By publicising our findings on local issues derived for example from local source apportionment, we have the potential to generate impact through region-specific public engagement, raising awareness of air pollution sources and the activities that drive emissions.

Description | Over half of direct particle emissions from road traffic is from non-exhaust emissions such as brake and tyre wear and resuspension. Highly time resolved measurements of the increment of key tracers for these sources at the busy central roadside measurement site, above the urban background, were used to calculate improved assessments of emission factors for these sources. Brake wear was found to be the highest average non-exhaust emission source. During Covid lockdown, changes in traffic flow and dryer weather allowed us to demonstrate that the tyre and resuspension non-exhaust emissions were dependent upon speed and road surface wetness conditions. We used these results to predict brake, tyre, and road wear emission estimates for passenger cars in the UK based on changes in modelled traffic volume and battery electric vehicle uptake (vehicle mass, and regenerative braking). We found that the reduction in emissions due to regenerative braking (~60-90% reduction depending on drive cycle used) was predicted to mitigate increased tyre and road wear emissions due to increased mass and vehicle use. We have also undertaken detailed modelling of the impact of regenerative braking on emissions to better quantify the emission reduction with industry partners (Bosch) |
Exploitation Route | There is a high level of uncertainty in current emission factors for non-exhaust emissions. The novel use of the CO2 dilution method provides a method for similar work to be repeated in other other locations. The new emission factors can be used by other researchers and policy makers to assess the impact of non-exhaust emissions currently and in the future. |

PI Contribution | The NTU-ICL collaboration aimed to set up a research partnership to study lead and other toxic contaminants in atmospheric particulate matter in Singapore and was supported by a £8,000 travel grant from Imperial College London for UK partners. This enabled knowledge exchange between specialist groups at ICL and NTU to produce a preliminary data set that will be critical for larger funding applications. During the pre-study, we aim (i) to identify the sources of lead and of atmospheric particulate matter and (ii) to determine the size fraction with the highest lead content. We sampled potential source materials for lead and PM (i.e., road dust, tires, brakes) and we will collect PM outdoors at different locations. We conducted different examinations of the PM in the relevant labs at ICL: magnetic properties, Pb isotope ratio and concentration analysis. The later also enabled the NTU group to get experience with isotope and concentrations measurements using new tri-pole mass spectrometers based at ICL. |

Results and Impact | Tyres shed approximately six million tonnes of material per year and are widely recognised as a considerable source of vehicle emissions. A limit on tyre wear is likely to be included in Euro 7 legislation. There is increased scrutiny regarding tyre ingredients and their environmental impact, particularly compounds such as the preservative 6PPD, cited for depleting fish stocks. This workshop engaged both industry experts and academia in sharing their research and perspectives. It resulted in a broadening of awareness from different participant groups and a deeper level of collaboration between industry and academia. |

Results and Impact | In the past few decades, research has focused on the question of how the toxicity of particulate matter (PM) varies by source, composition, and size. HEI previously supported the National Particle Component Toxicity (NPACT) Initiative, which involved coordinated epidemiologic and toxicologic studies to evaluate the relative toxicity of various chemical and physical properties of PM. The results indicated that component composition influences health effects, but that there was no "silver bullet" to guide regulatory efforts pointing to specific sources as being more or less toxic than other sources. More recently, HEI's program Assessing Health Effects of Long-Term Exposure to Low Levels of Ambient Air Pollution, funded three large epidemiological studies to evaluate long-term PM exposure and mortality in Canada, the United States, and Europe. The results demonstrated health effects at the lowest observed exposure concentrations, which were below the current regulatory standards in the United States. Now, HEI seeks to embark on the next stage of innovative and policy relevant research on PM health effects. Feedback from HEI sponsors, the Research Committee, and other experts identified several areas of interest, including further evidence of biological plausibility for PM toxicity and disease progression at low doses and a clearer understanding of how peak and long-term average PM exposures influence health effects. Although substantial evidence in support of a causal relationship between short- and long-term exposure to PM and adverse health effects exists, there are several factors that might preempt the justification to further lowering regulatory values. These factors include 1) the lack of mechanistic toxicity studies at low exposures to help explain observed human health effects, 2) insufficient clarity on different personal exposure patterns and their link with specific health effects, 3) how episodic PM exposures affect health, and 4) the evolving nature of PM components. Further clarity on these issues could inform interventions or policies to protect health. To identify specific research needs and priorities for the development of a new research program on PM health effects, HEI will host an invite-only 2-day scoping workshop with leading experts. Deliverables will include a summary document of the workshop findings that will be publicly disseminated for the greater scientific community, and recommendations for critical research needs that are feasible for HEI to address in a 2024 Research Funding Announcement. This workshop focused on research critical for informing policy in the United States where the HEI Core program has a long history of informing policy. However, participants will include experts and stakeholders from around the world. |
