SEGH members were delighted to attend and participate in the 9th International Symposium on Environmental Geochemistry organised by staff from the University of Aveiro held during 15th - 22nd of July, 2012.

The local organising committee and international scientific committee was chaired by Professor Eduardo Anselmo Ferreira da Silva (Geosciences Department, Aveiro University, Portugal), supported by colleagues from across the University and by the IAGC - International Association of Geochemistry, the SEGH - Society of Environmental Geochemistry and Health and the IMGA - International Medical Geology Association, which were represented in the event by Clemens Reimann (President of the IAGC), Xiang-dong Li (President of SEGH), Andrew Hursthouse (European Chair of SEGH) and José Centeno (Chairman of the IMGA). The conference was sponsored by:

 

  • ·         GeoBioTec Research Unit
  • ·         Cesam Research Centre
  • ·         Delta Cafés
  • ·         PLM
  • ·         Fundação Calouste Gulbenkian
  • ·         TAP Portugal

The conference involved four pre-conference short-courses, a scientific program (plenary lectures, oral and poster presentations) of 5 days and a post-conference field trip.

The eight plenary sessions provided a wide range of topics across environmental geochemistry interests including:

  • “Environmental health impact of legacy uranium mining in Portugal” by Fernando Carvalho,
  • “Challenges in Environmental geochemistry & health: health and its costs and future research priorities?” a joint platform presentation by Alex Stewart and Andrew Hursthouse,
  • “Geochemical reactivity and risk assessment: from scientific data to policy applications” by Paul Römkens
  • “Petroleum contamination assessment and bio-remediation processes” by Joan Albaiges,
  • “Remediation of municipal waste waters by artificial wetlands” by Joan Bayona,
  • “The role of geostatistics in environmental epidemiology” by Pierre Goovaerts.

From the 259 abstracts submitted to the conference, 128 were selected for oral presentations and 131 for poster. Over 250 participants representing 37 countries (Argentina, Australia, Brazil, Canada, China, Croatia, Finland, France, Germany, Greece, Hungary, Iran, Ireland, Italy, Japan, Korea, Mexico, Mozambique, Namibia, Nigeria, Norway, Poland, Portugal, Republic of Macedonia, Russia, Serbia, Slovak Republic, Slovenia, South Africa, Spain, The Netherlands, Tunisia, Turkey, United Kingdom, USA, Venezuela, Vietnam), have attended the conference.

 

The sessions were organized according to the following themes:

1-Geochemical records of environmental changes: climate changes and human activities

Convener: Jonh Farmer, Malin Kylander and François de Vleeschouwer

2-Sustainability in Mining and Related Environmental Issues

3-Geochemistry and Health & Medical Geology

4-Environmental Toxicology & Epidemiology

5-Environmental contamination and remediation

6-Water resources and aquatic environments

7-Biogeochemistry of trace elements, organic pollutants and radio-nuclides

8-Environmental Analytical Geochemistry

9-Modelling Environmental Systems: GIS platforms and Data Analysis

10-Perception and communication of environmental health risks and social inequality

11- Observatoire Hommes-Milieux (OHM) Special session

Forty participants attended to the “Nanomaterials, Environment and Health”, "Arsenic and Mercury in the Environment", "Human bioaccessibility of potentially harmful elements in the solid phase: risk assessment aspects of using bioaccessibility data" and "International Short Course on Medical Geology Health and Earth ‐ Building a Safer Environment" short-courses, and twenty participated in the field-trip to the uranium mines.

About 100 participants attended to the Conference Dinner at the Aliança Cellars where delegates were treated to a tour of a remarkable display of art and rock and mineral specimens collected by the company.

During the meeting six prizes were awarded to post-graduation students, 3 for the best oral presentations and 3 for the best posters. Short articles on the winning presentations will follow on the SEGH website.

Finally, discussions amongst the board members of the supporting Societies agreed a mechanism to jointly promote the ISEG conference series and news of the venue of the next meeting will be made available shortly.

  • Spatial variability and geochemistry of rare earth elements in soils from the largest uranium–phosphate deposit of Brazil 2018-02-22

    Abstract

    The Itataia uranium–phosphate deposit is the largest uranium reserve in Brazil. Rare earth elements (REEs) are commonly associated with phosphate deposits; however, there are no studies on the concentrations of REEs in soils of the Itataia deposit region. Thus, the objective of the research was to evaluate the concentration and spatial variability of REEs in topsoils of Itataia phosphate deposit region. In addition, the influence of soil properties on the geochemistry of REEs was investigated. Results showed that relatively high mean concentrations (mg kg−1) of heavy REEs (Gd 6.01; Tb 1.25; Ho 1.15; Er 4.05; Tm 0.64; Yb 4.61; Lu 0.65) were found in surface soils samples. Soil properties showed weak influence on the geochemical behavior of REEs in soils, except for the clay content. On the other hand, parent material characteristics, such as P and U, had strong influence on REEs concentrations. Spatial distribution patterns of REEs in soils are clearly associated with P and U contents. Therefore, geochemical surveys aiming at the delineation of ore-bearing zones in the region can benefit from our data. The results of this work reinforce the perspective for co-mining of P, U and REEs in this important P–U reserve.

  • Seasonal occurrence, source evaluation and ecological risk assessment of polycyclic aromatic hydrocarbons in industrial and agricultural effluents discharged in Wadi El Bey (Tunisia) 2018-02-13

    Abstract

    Polycyclic aromatic hydrocarbons are of great concern due to their persistence, bioaccumulation and toxic properties. The occurrence, source and ecological risk assessment of 26 polycyclic aromatic hydrocarbons in industrial and agricultural effluents affecting the Wadi El Bey watershed were investigated by means of gas chromatographic/mass spectrometric analysis (GC/MS). Total PAHs (∑ 26 PAH) ranged from 1.21 to 91.7 µg/L. The 4- and 5-ring compounds were the principal PAHs detected in most of 5 sites examined. Diagnostic concentration ratios and molecular indices were performed to identify the PAH sources. Results show that PAHs could originate from petrogenic, pyrolytic and mixed sources. According to the ecotoxicological assessment, the potential risk associated with PAHs affecting agricultural and industrial effluents ranged from moderate to high for both aquatic ecosystem and human health. The toxic equivalency factor (TEF) approach indicated that benzo[a]pyrene and benz[a]anthracene were the principal responsible for carcinogenic power of samples.
