Dr Jane Entwistle is Head of Department of Geography at Northumbria University and is organising the 2014 SEGH conference. Here she gives some insight into the host organisation and city.

The Department of Geography at Northumbria University are delighted to host the 2014 SEGH conference. The conference oral and poster sessions will run over 3 days (1st – 3rd July), with a pre-conference workshop (30th June) led by Dr Mark Cave and Dr Joanna Wragg of the British Geological Survey, and a post-conference excursion (4th July) taking in some of the sights the North East of England has to offer, including a stop on Hadrian’s Wall. For specific details of the conference programme, keynote and invited speakers please go to www.northumbria.ac.uk/segh2014.

Northumbria University, in Newcastle upon Tyne, is renowned for the excellence of its teaching, as well as its research. Based in the popular, safe and vibrant city of Newcastle upon Tyne, Northumbria offers you one of the best academic and social experiences possible. Newcastle is known for its lively nightlife and friendly inhabitants, and is home to the world famous Newcastle United premier league football club and its 'Toon Army' (St James's Park stadium is situated in the city centre, only a 10 minute stroll from the campus). Newcastle also has its own Chinatown, several art galleries and museums, and Antony Gormley's Angel of the North stands on a low hill next to the main A1 southern road approach to Newcastle. The city is steeped in history having originated as a Roman settlement on the banks of the River Tyne over 2000 years ago. Newcastle is also the gateway to the spectacular Northumberland Coast with its sandy beaches and stunning coastal castles.

The University itself was formed in 1969 from the amalgamation of three regional colleges and today is the largest university in the North East of England with a student population of around 33,000 from over 125 countries. The Department of Geography sits within one of four faculties, the Faculty of Engineering and Environment. Research in the Department focuses around three research groups, with strong synergies between these groups:

Cold and Palaeo Environments. Members of the group work in polar and high mountain environments addressing key problems in Earth Systems Science. Current research includes: glacier mass balance, ice/water/sediment interaction and ice sheet dynamics; slope and coastal cliff processes and large landslide deposits; palaeo-biogeography and palaeo-biome reconstruction for modelling past climates; fluvial processes in large Arctic river systems; environmental microbiology; and subglacial lakes, as part of the Lake Ellsworth Consortium.

Communities and Resilience. Members of the group work in diverse topics from the localism of community engagement and social inclusion to the internationalism of world city economics and disaster risk reduction across Africa and Asia. The group also hosts the Disasters and Development Network (DDN), which aims to develop through research, teaching and learning, the knowledge and skills to address hazards, disasters and complex emergencies from the perspective of different development debates and experience.

Environmental Geochemistry and Ecology. Research in this area is focused upon the sustainability of the physical, chemical and biological environment. There is a strong focus on the application of these fields to problems from the local to global scale. This approach is supported by the Northumbrian Environmental Training and Research Centre (NETREC), a dedicated research, consultancy and training unit that has been running since 1996. NETREC operates the North of England Air Quality in Major Incidents Service on behalf of the UK Environment Agency. Current research includes: environmental analysis to detect and model bioavailability and bioaccessibility of metals and other pollutants in the environment and the associated risks to human health; ecological resilience and climatic impacts on biodiversity; carbon capture and ecosystem services.

Recently refurbished laboratories provide facilities for environmental geochemistry and microbiology, in addition to a dedicated laboratory (including core storage, HF fume cupboard, micro-balance and microscope rooms) for palaeo-environmental research. Available instrumentation includes Inductively Coupled Plasma Atomic Emission Spectrometry; High Performance Liquid Chromatography; Gas Chromatography and Liquid Chromatography Mass Spectrometry; Scanning Electron Microscope with energy dispersive spectrometry; and a Flash 2000 organic elemental analyser. Over £0.5 million has been invested in field equipment including: terrestrial laser scanner with ~2km range; sub-bottom profiler for lakes and offshore surveys; portable XRF system; global positioning systems for precise point positioning; state-of-the-art unmanned aerial vehicles with high-resolution cameras for DEM generation and change detection; novel bespoke borehole radar equipment; ground-penetrating radar; seismic equipment; meteorological and air-monitoring equipment; and lake coring equipment.

We look forward to welcoming you to Newcastle and to Northumbria University and of course we will be happy to arrange a tour of the facilities during the conference.

  • Date palm waste biochars alter a soil respiration, microbial biomass carbon, and heavy metal mobility in contaminated mined soil 2017-04-19

    Abstract

    A 30-day incubation experiment was conducted using a heavy metal-contaminated mined soil amended with date palm feedstock (FS) and its derivative biochars (BCs) at three pyrolysis temperatures of 300 (BC-300), 500 (BC-500), and 700 °C (BC-700) with different application rates (0.0, 5, 15, and 30 g kg−1) to investigate their short-term effects on soil respiration (CO2–C efflux), microbial biomass carbon (MBC), soil organic carbon (SOC), mobile fraction of heavy metals (Cd, Cu, Pb, Zn, Mn, and Fe), pH, and electrical conductivity (EC). The results showed that FS and BC-300 with increasing addition rate significantly reduced soil pH, whereas SOC, CO2–C efflux, and soil MBC were increased compared to the control. On the contrary, BC-500 and BC-700 increased soil pH at early stage of incubation and have small or no effects on SOC, CO2–C efflux, and MBC. Based on the results, the date palm biochars exhibited much lower cumulative CO2–C efflux than feedstock, even with low-temperature biochar, indicating that BCs have C sequestration potential. Applying BC-700 at 15 and 30 g kg−1 significantly reduced cumulative CO2–C efflux by 21.8 and 45.4% compared to the control, respectively. The incorporation of FS into contaminated soil significantly increased the mobile content of Cd and Mn, but decreased the mobile content of Cu. However, BC-300 significantly reduced the mobile content of Cd, Cu, Pb, and Zn. It could be concluded that low-temperature biochar could be used as a soil amendment for reducing heavy metal mobility in mining contaminated soil in addition to minimize soil CO2–C efflux.

  • Historical record of anthropogenic polycyclic aromatic hydrocarbons in a lake sediment from the southern Tibetan Plateau 2017-04-17

    Abstract

    High-altitude lake sediments can be used as natural archives to reconstruct the history of pollutants. In this work, the temporal distribution of polycyclic aromatic hydrocarbons (PAHs) was determined in a sediment core collected from the southern Tibetan Plateau (TP), which was dated by using the 210Pb dating method and validated with the 137Cs fallout peak. The concentrations of the anthropogenic PAHs (Σ8PAH) in the sediment core ranged from 0.83 to 12 ng/g dw, and the fluxes of the Σ8PAH were in the range of 2.1–27 g/cm2/year. The temporal variations in the concentration and input flux of anthropogenic PAHs were low with little variability before the 1950s, and then gradually increased from the 1950s to the 1980s, and an accelerated increase was observed after the early 1980s. The content of total organic carbon played an insignificant role in affecting the time trends of PAHs in the sediment core. Diagnostic concentration fractions of PAH components indicate PAHs in the lake sediment of the southern TP which are mainly from biomass burning and/or from long-range atmospheric transport.

  • Determination of the potential implementation impact of 2016 ministry of environmental protection generic assessment criteria for potentially contaminated sites in China 2017-04-12

    Abstract

    The Ministry of Environmental Protection of China issued a 3rd draft edition of risk-based Generic Assessment Criteria (the MEP-GAC) in March 2016. Since these will be the first authoritative GAC in China, their implementation is likely to have a significant impact on China’s growing contaminated land management sector. This study aims to determine the potential implementation impact of the MEP-GAC through an in-depth analysis of the management context, land use scenarios, health criteria values adopted and exposure pathways considered. The MEP-GAC have been proposed for two broad categories of land use scenarios for contaminated land risk assessment, and these two categories of land use scenarios need to be further delved, and a MEP-GAC for Chinese cultivated land scenario ought to be developed, to ensure human health protection of Chinese farmers. The MEP-GAC have adopted 10−6 as the acceptable lifetime cancer risk, given the widespread extent and severe level of land contamination in China, consideration should be given to the decision on excess lifetime cancer risk of 10−5. During risk assessment process in practice, it is better to review the 20% TDI against local circumstances to determine their suitability before adopting it. The MEP-GAC are based on a SOM value of 1%, for regions with particularly high SOM, it might be necessary to develop regional GAC, due to SOM’s significant impact on the GAC developed. An authoritative risk assessment model developed based on HJ25.3-2014 would help facilitate the DQRA process in practice. The MEP-GAC could better reflect the likely exposures of China’s citizens due to vapour inhalation by using characteristics of Chinese exposure scenarios, including China-generic building stock, as inputs into the Johnson and Ettinger model as opposed to adoption of the US EPA parameters. The MEP-GAC once implemented will set the trajectory for the development of the investigation, assessment and remediation of land contamination for years.
