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

We look forward to welcoming you to Newcastle in 2014.

 

Best Regards,

Jane Entwistle [SEGH 2014 Chair]

  • Positive anomalous concentrations of Pb in some gabbroic rocks of Afikpo basin southeastern Nigeria 2016-08-01

    Abstract

    Gabbroic rocks have intruded the sedimentary sequence at Ameta in Afikpo basin southeastern Nigeria. Petrographic and geochemical features of the rocks were studied in order to evaluate their genetic and geotectonic history. The petrographic results show that the rocks contain plagioclase, olivine, pyroxene, biotite, iron oxide, and traces of quartz in three samples. Major element characteristics show that the rocks are subalkaline. In addition, the rocks have geochemical characteristics similar to basaltic andesites. The trace elements results show inconsistent concentrations of high field strength elements (Zr, Nb, Th, Ta), moderate enrichment of large-ion lithophile elements (Rb, Sr, Ba) and low concentrations of Ni and Cr. Rare earth element results show that the rocks are characterized by enrichment of light rare earth elements, middle rare earth elements enrichment, and depletion of heavy rare earth elements with slight positive europium anomalies. Zinc concentrations are within the normal range in basaltic rocks. There are extremely high concentrations of Pb in three of the rock samples. The high Pb concentrations in some of these rocks could be as a result of last episodes of magmatic crystallization. The rocks intruded the Asu River Group; organic components in the sedimentary sequence probably contain Pb which has been assimilated into the magma at the evolutionary stage of the magma. Weathering of some rocks that contain galena could lead to an increase in the concentration of lead in the gabbroic rocks, especially when the migration and crystallization of magma take place in an aqueous environment. Nevertheless, high concentration of lead is hazardous to health and environment.

  • Estimated lead (Pb) exposures for a population of urban community gardeners 2016-08-01

    Abstract

    Urban community gardens provide affordable, locally grown, healthy foods and many other benefits. However, urban garden soils can contain lead (Pb) that may pose risks to human health. To help evaluate these risks, we measured Pb concentrations in soil, vegetables, and chicken eggs from New York City community gardens, and we asked gardeners about vegetable consumption and time spent in the garden. We then estimated Pb intakes deterministically and probabilistically for adult gardeners, children who spend time in the garden, and adult (non-gardener) household members. Most central tendency Pb intakes were below provisional total tolerable intake (PTTI) levels. High contact intakes generally exceeded PTTIs. Probabilistic estimates showed approximately 40 % of children and 10 % of gardeners exceeding PTTIs. Children’s exposure came primarily from dust ingestion and exposure to higher Pb soil between beds. Gardeners’ Pb intakes were comparable to children’s (in µg/day) but were dominated by vegetable consumption. Adult household members ate less garden-grown produce than gardeners and had the lowest Pb intakes. Our results suggest that healthy gardening practices to reduce Pb exposure in urban community gardens should focus on encouraging cultivation of lower Pb vegetables (i.e., fruits) for adult gardeners and on covering higher Pb non-bed soils accessible to young children. However, the common practice of replacement of root-zone bed soil with clean soil (e.g., in raised beds) has many benefits and should also continue to be encouraged.
