30th SEGH Conference

30 June 2014
Newcastle, UK
Northumbria University, Newcastle-upon-Tyne, UK. 30th June to 4th July 2014 International Conference of the Society for Environmental Geochemistry and Health

Dear colleagues,

On behalf of the Organizing Committee of the 30th International SEGH conference (European Section), I would like to extend a warm welcome and invite you to join us at Northumbria University, Newcastle-upon-Tyne, UK, 30th June – 4th July, 2014.

This annual conference of the Society for Environmental Geochemistry and Health provides a forum for international scientists, consultants, regulatory authorities and other practitioners (public health / environmental health) with an interest in the links between environment and health and working in the broad area of environmental geochemistry. For the 30thSEGH we are keen to receive contributions on three core themes and two special sessions:

  •           Theme 1 - Chemical bioavailability and bioaccessibility
  •           Theme 2 - Risk Assessment, environmental exposure and health
  •           Theme 3 - Air & dust pollution and human health
  •           Special Session 1 - ‘Hydraulic Fracturing (Fracking) and Health’
  •           Special Session 2 - ‘Environmental iodine and the deficiency disorders’

We would also welcome submission of papers for any topics relevant to the aims of the Society.

 

The conference venue is the city campus of Northumbria University, in the heart of the city of Newcastle-upon-Tyne, North-East England, UK.

 

Abstract submission will open on December 2nd, 2013.

Abstract submission deadline is March 3rd, 2014

Please save these key dates in your diary. More information will follow...

We look forward to welcoming you to Newcastle in 2014.

 

Best Regards,

Jane Entwistle [SEGH 2014 Chair]

  • Urinary stones as a novel matrix for human biomonitoring of toxic and essential elements 2015-03-04

    Abstract

    Monitoring of body burden of toxic elements is usually based on analysis of concentration of particular elements in blood, urine and/or hair. Analysis of these matrices, however, predominantly reflects short- or medium-term exposure to trace elements or pollutants. In this work, urinary stones were investigated as a matrix for monitoring long-term exposure to toxic and essential elements. A total of 431 samples of urinary calculi were subjected to mineralogical and elemental analysis by infrared spectroscopy and inductively coupled plasma mass spectrometry. The effect of mineralogical composition of the stones and other parameters such as sex, age and geographical location on contents of trace and minor elements is presented. Our results demonstrate the applicability of such approach and confirm that the analysis of urinary calculi can be helpful in providing complementary information on human exposure to trace metals and their excretion. Analysis of whewellite stones (calcium oxalate monohydrate) with content of phosphorus <0.6 % has been proved to be a promising tool for biomonitoring of trace and minor elements.

  • A novel method of microwave heating mixed liquid-assisted regeneration of V 2 O 5 –WO 3 /TiO 2 commercial SCR catalysts 2015-03-03

    Abstract

    An experimental study on the regeneration of deactivated SCR catalysts was carried out using a microwave-assisted method containing three steps of washing with mixed liquid of ethanol and water, impregnating, and drying. After the regeneration treatment, NO conversion at 320 °C increased from 39 to 90 % and vanadium content increased by 62.2 %, which were much higher than those regenerated by the traditional method. The more impregnated vanadium was due to the fact that the rapid evaporation of mixed liquid inside the catalyst channels led to the enlargement of surface areas by creating more pores on the catalysts. Meanwhile, with the increasing concentrations of ethanol, the heating rate of the mixed liquid increased, and the volume after complete evaporation of the mixed liquid was gradually reduced. Since higher heating rate and lager volume after the liquid evaporation could help to create more pores, therefore, when the volume ratio of ethanol/mixed solution was 20 %, the catalyst obtained the maximum specific surface area, which significantly increased to ca. 123 % compared with the deactivated catalyst. In addition, the catalyst dried by microwave exhibited better catalytic activity than that dried in conventional oven. Therefore, this method showed great potential in industrial applications.

  • Assessment of total and organic vanadium levels and their bioaccumulation in edible sea cucumbers: tissues distribution, inter-species-specific, locational differences and seasonal variations 2015-03-03

    Abstract

    The objective of this study is to investigate the levels, inter-species-specific, locational differences and seasonal variations of vanadium in sea cucumbers and to validate further several potential factors controlling the distribution of metals in sea cucumbers. Vanadium levels were evaluated in samples of edible sea cucumbers and were demonstrated exhibit differences in different seasons, species and sampling sites. High vanadium concentrations were measured in the sea cucumbers, and all of the vanadium detected was in an organic form. Mean vanadium concentrations were considerably higher in the blood (sea cucumber) than in the other studied tissues. The highest concentration of vanadium (2.56 μg g−1), as well as a higher degree of organic vanadium (85.5 %), was observed in the Holothuria scabra samples compared with all other samples. Vanadium levels in Apostichopus japonicus from Bohai Bay and Yellow Sea have marked seasonal variations. Average values of 1.09 μg g−1 of total vanadium and 0.79 μg g−1 of organic vanadium were obtained in various species of sea cucumbers. Significant positive correlations between vanadium in the seawater and V org in the sea cucumber (r = 81.67 %, p = 0.00), as well as between vanadium in the sediment and V org in the sea cucumber (r = 77.98 %, p = 0.00), were observed. Vanadium concentrations depend on the seasons (salinity, temperature), species, sampling sites and seawater environment (seawater, sediment). Given the adverse toxicological effects of inorganic vanadium and positive roles in controlling the development of diabetes in humans, a regular monitoring programme of vanadium content in edible sea cucumbers can be recommended.
