32nd International SEGH conference, Universite Libre de Bruxelles, Brussels, Belgium, 4th-8th July, 2016.

Dear All,

On behalf of the Organising Committee of the 32nd International SEGH conference, I would like to invite you to join us at the Universite Libre de Bruxelles, Brussels, Belgium, 4th-8th July, 2016.

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 32nd SEGH we are keen to receive contributions on three core themes and three special sessions:

• Theme 1 – Dust and Aerosol: Environmental records of Anthropogenic

• Theme 2 – Isotopes and Speciation

• Theme 3 – Geochemistry and Health

• Special Session 1 – SpatioTemporal Trends of Metal Contaminants in the Atmosphere

• Special Session 2 – Nanoparticles in the Environment: Fate and Effects

• Special Session 3 – Geochemistry and Biomedical Issues

The conference venue is the city campus of Université Libre de Bruxelles, in the heart of the city of Brussels, Belgium, will offer you the opportunity to visit an amazing cultural heritage, rich in European History, to taste a fascinating cuisine (chocolates, beers, ...), and participate to the Belgian life style. The venue takes benefit of accessibilities from much of the world, and numerous good-quality affordable accommodations.

My research Lab, Laboratoire G-Time ( ), will be very happy to welcome you and offer you the opportunity to visit our analytical facilities. Our research focuses on applications of radiogenic and non-traditional stable isotopes in geosciences (Environmental Geochemistry, Mantle Geodynamics and Cosmochemistry). My main research interest is dedicated to the Biogeochemistry of Metal Trace Elements in the Environment. The core of our work remains the applications of non-traditional stable isotopes (Zn, Cd, Cu, Fe) in addition to traditional radiogenic isotopes (Pb, Hf, Nd, ...), as tracers of sources and processes of global biogeochemical cycles, environmental pollution and paleo-environmental reconstruction.

We look forward to welcoming you to Brussels in 2016.

Best Regards,

  • Improving arsenopyrite oxidation rate laws: implications for arsenic mobilization during aquifer storage and recovery (ASR) 2018-04-25


    Aquifer storage and recovery (ASR) and aquifer recharge (AR) provide technical solutions to address water supply deficits and growing future water demands. Unfortunately, the mobilization of naturally present arsenic due to ASR/AR operations has undermined its application on a larger scale. Predicting arsenic mobility in the subsurface during ASR/AR is further complicated by site-specific factors, including the arsenic mobilization mechanisms, groundwater flow conditions, and multi-phase geochemical interactions. In order to ensure safe and sustainable ASR/AR operation, a better understanding of these factors is needed. The current study thus aims to better characterize and model arsenic remobilization at ASR/AR sites by compiling and analyzing available kinetic data on arsenic mobilization from arsenopyrite under different aqueous conditions. More robust and widely applicable rate laws are developed for geochemical conditions relevant to ASR/AR. Sensitivity analysis of these new rate laws gives further insight into the controlling geochemical factors for arsenic mobilization. When improved rate laws are incorporated as the inputs for reactive transport modeling, arsenic mobilization in ASR/AR operations can be predicted with an improved accuracy. The outcomes will be used to guide groundwater monitoring and specify ASR/AR operational parameters, including water pretreatment requirements prior to injection.

  • Heavy metal exposure has adverse effects on the growth and development of preschool children 2018-04-25


    The purpose of this study was to investigate the associations between levels of lead (Pb), cadmium (Cd), chromium (Cr), and manganese (Mn) in the PM2.5 and blood and physical growth, and development parameters including birth length and weight, height, weight, body mass index (BMI), head circumference, and chest circumference in preschool children from Guiyu (e-waste exposure area) and Haojiang (the reference area). A total of 470 preschool children from Guiyu and Haojiang located in southeast coast of China were recruited and required to undergo physical examination and blood tests during the study period. Birth length and weight were obtained by birth records and questionnaire. Pb and Cd in both PM2.5 and blood were significantly higher in Guiyu than Haojiang. Remarkably, the children of Guiyu had significantly lower birth weight and length, BMI, and chest circumference when compare to their peers from the reference area (all p value < 0.05). Spearman correlation analyses showed that blood Pb was negatively correlated with height (r = −0.130, p < 0.001), weight (r = −0.169, p < 0.001), BMI (r = −0.100, p < 0.05), head circumference (r = −0.095, p < 0.05), and chest circumference (r = −0.112, p < 0.05). After adjustment for the potential confounders in further linear regression analyses, blood Pb was negatively associated with height (β = −0.066, p < 0.05), weight (β = −0.119, p < 0.001), head circumference (β = −0.123, p < 0.01), and chest circumference (β = −0.104, p < 0.05), respectively. No significant association between blood Cd, Cr, or Mn was found with any of our developmental outcomes. Taken together, lead exposure limits or delays the growth and development of preschool children.

  • Contamination characteristics of trace metals in dust from different levels of roads of a heavily air-polluted city in north China 2018-04-24


    Concentrations of eight trace metals (TMs) in road dust (RD) (particles < 25 μm) from urban areas of Xinxiang, China, were determined by inductively coupled plasma mass spectrometry. The geometric mean concentrations of Zn, Mn, Pb, As, Cu, Cr, Ni and Cd were 489, 350, 114, 101, 60.0, 39.7, 31.6, and 5.1 mg kg−1, respectively. When compared with TM levels in background soil, the samples generally display elevated TM concentrations, except for Cr and Mn, and for Cd the enrichment value was 69.6. Spatial variations indicated TMs in RD from park path would have similar sources with main roads, collector streets and bypasses. Average daily exposure doses of the studied TMs were about three orders of magnitude higher for hand-to-mouth ingestion than dermal contact, and the exposure doses for children were 9.33 times higher than that for adults. The decreasing trend of calculated hazard indexes (HI) for the eight elements was As > Pb > Cr > Mn > Cd > Zn > Ni > Cu for both children and adults.
