The results of commissioned research by Aberystwyth University (AU) have shaped decision-making that led to the relocation of refugee Roma, Ashkali and Egyptian (RAE) communities in Mitrovica, northern Kosovo. In 2009/2010 AU research unequivocally identified the source of elevated lead (Pb) levels in soils that had been blamed for high infant and adult mortality rates in RAE refugee camps, and established that Roma Mahalla had sufficiently low soil Pb levels to permit the construction of a purpose-built housing development for the RAE communities. Following the relocation of the RAE families to Roma Mahalla in 2010/2011 there has been a significant reduction in blood Pb levels in children with no reported deaths attributable to Pb poisoning. This AU research project has had a demonstrable positive impact on life quality and human health of the resettled RAE communities living in Mitrovica.
The science conducted in environmental radioactivity and radioecology ranges from the development and deployment of detection systems to the characterisation and implementation of radiological risk assessment tools. This has led to impacts in international standards, regulation development and regulation enforcement, including: advising the Scottish Environment Protection Agency (SEPA) on hot particle hazard, risk, detection and recovery; developing the framework for environmental protection through the International Commission on Radiological Protection; developing standard specifications for the manufacture of environmental monitoring equipment for the International Electrotechnical Commission; and providing training courses through the International Atomic Energy Agency.
UK and international government departments, agencies and the nuclear industry have benefitted from improved understanding of environmental radioactivity and the development of novel, in situ gamma spectroscopy by researchers at the Scottish Universities Environmental Research Centre (SUERC, University of Glasgow). The provision of advice and novel data has helped to develop management, monitoring, regulation and human dose assessments for authorised and accidental releases of radionuclides, and to build plans for geological disposal facilities for high and intermediate level radioactive waste.
The development and marketing of the Chemcatcher passive sampler has significantly improved the way water quality is monitored. These cost-effective devices are either used alongside or can replace established approaches that rely on infrequent spot or bottle sampling. We have contributed to the development of national and international standards for the use of passive samplers, and the dissemination of results to end users has facilitated the uptake of passive sampling technology worldwide. Our passive samplers have been used to monitor a diverse range of environmental problems, from pharmaceuticals in drinking water to the release of radioactive caesium after the Fukushima nuclear reactor incident in Japan.
Researchers at the University of St Andrews have changed the way environmental monitoring and impact assessment data are collected and analysed, particularly in the marine environment. We have developed new statistical models of wildlife population dynamics that, for example, form the basis for population assessment of most of the world's grey seals, allowing the UK and Canadian governments to implement effective management of the populations. Other research carried out by us has led to reformulation of the recommended standard statistical practice for impact assessment in the UK marine renewables industry, enabling marine regulators such as Marine Scotland to make better-informed licensing decisions concerning large-scale offshore renewable energy developments.
The Green Guide to Specification is an environmental profiling system that enables designers and constructors to select building materials and components which have the lowest environmental impact. Designed and developed at Oxford Brookes University, the Green Guide methodology provides the construction industry with reliable environmental evaluations based on quantitative Life Cycle Assessment (LCA) data. Now in its 4th edition and part of the BREEAM and Code for Sustainable Homes programmes, Green Guide has been used to reduce environmental impacts for over 230,000 recorded construction projects, with a further 1.07 million projects registered awaiting certification worldwide. In 2009, the Green Guide was adopted as the official design standard for all construction materials used in the London 2012 Olympics.
The mapping and monitoring of land cover, habitats and forest structure through satellite-based observation by government and commercial organisations around the world has been enhanced by data analysis techniques and tools developed by the Earth Observation and Ecosystem Dynamics (EOED) Laboratory at Aberystwyth University (AU). This has allowed new commercial services to be provided and has change professional working practices. The key impacts include (i) improved knowledge and information about land cover and environmental change in forest and brigalow ecosystems in Australia, supporting effective management strategies; (ii) the completion of a comprehensive digital map of habitats in Wales to inform policy-making; and (iii) the increased capacity of the global remote sensing community in forest characterisation using open source software developed by AU.
OxCal is the most popular software package world-wide for calibrating and analysing dates within the carbon dating process, enabling the accurate dating of objects from the past. The brainchild of Prof. Christopher Bronk Ramsey, Director of the Oxford Radiocarbon Accelerator Unit (ORAU), OxCal is based on chronologies refined by the use of Bayesian statistical methods, and provides users with access to high-quality calibration of chronological data, now the basis for global chronologies. It is available online and free to download, and has played a highly significant role in establishing the ORAU as one of the pre-eminent international radiocarbon dating facilities. Funded by the NERC, and used widely within professional archaeology as well as other disciplines, OxCal has also played a key role in research projects (within Oxford and beyond) brought to the attention of the general public by the media.
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.
In May 2013 the UN Environment Programme's Stockholm Convention on Persistent Organic Pollutants agreed to ban the widely-used flame retardant Hexabromocyclododecane (HBCD), following evidence that there may be harmful human exposure. Since the Convention came into force in 2004, only 21 compounds have had their use either banned or tightly restricted under its terms. Research findings from Stuart Harrad and his group at the University of Birmingham formed a significant element of the case used to support the ban on HBCD. Harrad's group provided the first measurements made anywhere in the world on concentrations of individual HBCD isomers in indoor dust leading to the realisation that the ingestion of indoor dust was a significant pathway of human exposure to HBCD. The group has also contributed important evidence of the capacity of HBCD to bioaccumulate and of its environmental persistence.
