Impact type: Public Policy
Significance: The research provided evidence for formulation of government policies to ameliorate poor air quality, to which fine particulate matter (PM2.5), O3 and NO2 are the most important contributors; PM2.5 alone reduces average life expectancy in the UK by 6 months and costs £9bn-£20bn a year. The research has been incorporated into UK national guidance and policy-evidence documents for Defra, the Health Protection Agency, and the Environment Agencies.
Beneficiaries are the public and the environment.
Research; date; attribution: EaStCHEM research (1995-2011) (a) established reliable techniques to measure NO2 for a national protocol, and (b) quantified the impact of pollutant emissions on PM2.5 and O3 concentrations, and on hospital admissions and deaths. Heal (EaStCHEM) led the research and wrote, collaboratively in some cases, the reports and the work cited.
Reach: UK wide.
Data generated by sensors on-board satellites orbiting the Earth have become extremely important to businesses and public sector organisations. They are the essential ingredient in satellite-enabled consumer services, from GoogleEarth to disaster management, insurance and agriculture. The Earth Observation Science group at Leicester has played a leading role in the transfer of cutting-edge Earth Observation techniques and know-how to the private and public sectors, enabling more businesses to use the technology for commercial gain. Leicester experience in technology translation led to its invited contribution to the UK space industry-led report to government, an Innovation and Growth Strategy for Space.
Evidence from research at UWE Bristol has enabled UK local and national governments and international governments (South Africa, Nigeria) to enhance their processes and procedures for managing air quality. UWE researchers have contributed to the policy and technical guidance issued by UK Governments, and they have directly advised the UK Government and devolved national and London administrations on legislation, regulation and official guidance. The research has contributed to the widespread recognition of the spatial extent of air quality problems, ensuring continued support of air quality management at a local level. The research activity and experience gained has been shared through international agencies, learned societies and interest groups. This extends to the EU, China, Brazil, and India, and specifically the Republic of South Africa through the development of the National Framework for Air Quality Management and in Nigeria through collaboration with the National Space Research and Development Agency.
Bristol ChemLabS (part of the School of Chemistry) has used School of Chemistry research on the atmosphere (air quality, atmospheric chemistry and the history of greenhouse gases on Earth) to enhance dramatically the quality and uptake of chemistry education in the UK and approximately 20 other nations. This radical advance has been achieved through ChemLabS' outreach activity, which has involved running more than 1,200 events for over 250,000 students over the past six years (and over 1,000 events since 2008). ChemLabS' atmospheric chemistry education packages are now being delivered in other countries, its textbooks/articles have been taken up across Europe, and it has trained more than 500 teachers directly. As a result of its activities, which are grounded in rigorous research, Bristol ChemLabS has been able to document increased interest in science and higher uptake at post-16 level.
Climate change is one of the most critical challenges facing modern society and there is a paramount requirement for government policy informed by science, and scientifically credible public information. Observations of sea surface temperatures, and their corroboration, are a focus for governments — climate change mitigation is economically important in a warming world. This UoA has provided the science leadership for a major satellite programme, the ATSRs, specifically designed to provide high-quality sea temperature data. Results from our research reduce uncertainties on global temperature change with unexpectedly wide benefits also to operational oceanography and weather forecasting. Public visibility through the Science Museum is also high.
Air pollution is a major health concern and government policy driver. Leeds researchers and colleagues have developed a detailed chemical mechanism which describes reactions in the lower atmosphere leading to the formation of ozone and secondary particulate matter, key air pollutants. The so-called `master chemical mechanism' (MCM) is considered the `gold standard' and has been used by the UK government and industry groups to inform their position on EU legislation and by the US EPA to validate and extend their regulatory models. The Hong Kong Environmental Protection Department has used the MCM to identify key ozone precursors and provide evidence for abatement strategies.
In the UK, 20-25% of the population (around 15 million people) sufferer from allergic rhinitis (hay fever) resulting in about 4 million `sick days' per year. Research undertaken by the National Pollen and Aerobiology Research Unit (NPARU) over a period of 20 years has resulted in the development of a national pollen forecasting system for the UK which has had direct benefits on the health and wellbeing of hay fever sufferers. This research has also raised awareness of the importance of pollen information for sufferers, fed into policy on allergy services (and subsequently practice of these services), underpinned training of health professionals, and informed clinical trials of anti-allergy products and devices.
Mineral separation by froth flotation is the largest tonnage separation process in the world, and is used to recover the very small fraction (<0.5%) of valuable mineral from the mined ore. Typically, 5-15% of the valuable minerals are not recovered due to sub-optimal process settings, most important of which is the air rate. A methodology to determine the optimal air rate range to use, Peak Air Recovery (PAR), was developed by the Froth and Foam Research Group at Imperial College London.
Anglo American Platinum produces 40% of the world's platinum. They use the PAR methodology on all their flotation plants to establish to air rate control limits, tightening the operating range and improving the separation performance. Rio Tinto annually produce 300 000 tons of copper and 500 000 oz gold from their Kennecott Copper mine. They have implemented PAR as a control strategy, and statistical comparative tests have shown an increase in copper and gold recovery from this mine alone of the order of 1%, with a nominal value of approximately $30m per annum.
Atmospheric science research in the Department of Chemistry, University of Cambridge has played a leading role in demonstrating the depletion of the ozone layer following anthropogenic emissions of halogenated compounds and other Ozone Depleting Substances (ODS). This research has been a key input into the series of assessment reports that have made the case to policy makers for the strengthening of the Montreal Protocol. The research underpinning these reports has made a vital contribution to a number of changes to the Protocol that have ensured a more rapid phase-out of a wider range of ODS and their replacements, leading to significant global health and climate benefits during the REF period. Researchers at Cambridge have helped to raise global awareness of these benefits, helping to maintain support for the Protocol among policy makers and the public, and supported European legislation to limit the environmental impact of ODS and their replacements.
Global waste disposal strategies and chemical regulations have been transformed through LEC's world-leading research into the environmental sources, fate and behaviour of persistent organic pollutants (POPs). Firstly, our research has directly supported controlled high temperature incineration as a long-term option for the disposal of municipal waste, by showing that well regulated incineration is not an environmentally significant source of dioxin emissions. Secondly, our research has maintained the controlled utilisation of sewage sludge (biosolids) on agricultural land as an effective risk-based management solution that re-cycles valuable carbon and nutrients to soil. Our research has underpinned the development of the UK's Dioxin Strategy and supported international chemicals regulation for one of the most important global flame retardant chemicals in current use under the Stockholm Convention.
