SEGH 2015 Conference Report

24 September 2015
Bratislava welcomed over 100 delegates from over 25 countries to SEGH 2015.

The Society for Environmental Geochemistry and Health (SEGH) in collaboration with The State Geological Institute of Dionýz Štúr, Bratislava and the project team of GEOHEALTH organised the 31st International SEGH Conference in Bratislava, June 22-26th 2015. The conference was organised under the auspices of Ministry of Environment of the Slovak Republic and supported by financial instrument Life+.

Bratislava welcomed over 100 delegates from over 25 countries to SEGH 2015.

The main conference topic was the link between environment and health.

More than 80 contributions presented at SEGH 2015 as oral presentations or posters were specialized across the three main thematic groups:

1.         Effects of contamination of the geological environment on human health

2.         Effect of the deficit or excess of chemical elements in the geological environment on human health

3.         Linking of geochemical and medical data.

The first two topics have received global attention for decades. The third thematic group is relatively new. Investigating the influences of the geological environment on human health is a challenging task and linking geochemical and medical data could be an effective approach.

Topic 1 attracted the majority of speakers who presented their studies on aspects of contamination of the geological environment including water, soil, stream sediments, air, food-chain, and the urban environment. Keynote lectures were given by: Stanislav Rapant (opening lecture), Andrew Hursthouse (urban environment), Andy Cundy (contaminated sites and wastes) and Taicheng An (risk assessment and analytical procedures). Special afternoon session by Chinese delegates brought innovative views on the analytical methods and procedures used for risk assessment.

Topics 2 and 3 were opened by 3 keynote speakers. František Koíšek and Alex Stewart brought us an overview of current knowledge within the topic “Deficit and/or excess of chemicals in the geological environment and their health effects on humans”. Mark Cave approached this issue by linking geochemical and health data through the use of health deprivation indices.

This year a student prize was given to Daniela Zuzolo from Italy for her poster
"Assessment of th environmental conditions of the Calore river basin (South Italy): a stream sediment approach". Congratulations.

The scientific programme of SEGH 2015 was built up from highly diversified keynote, plenary and poster lectures from various fields of research on relationship between environment and health and brought us a various views on the issue of the impact of contaminated geological environment on human health.

All conference details, photos and book of abstracts are available downloading on the conference website

During SEGH 2015 board a transfer of the post of SEGH President happened. We would like to thank ex-president Andrew Hursthouse for his leading of SEGH as well as we wish success to Chaosheng Zhang as new SEGH president.

The scientific programme was accompanied by social events including sightseeing tour by historical city train through the main historical sights of Bratislava city and conference dinner with local music that took place in a very pleasant restaurant in Holiday Inn Bratislava. All delegates participated on these events have enjoyed these social events. 

The second part of the excursion was the visit of open-air mining museum in Banská Štiavnica – the most significant historical mining town in the Slovak Republic, innscribed in the UNESCO World Heritage list. Surface as well as undeground exhibition offered to delegates an overview of mediavel historical times of mining of silver and gold in this region.

A special visit of SEGH chairman´s summer cottage in beautiful mountainous area of Banská Štiavnica region was a top end of the day.

Finally, we would like to thank all delegates coming from over the 20 countries for their participation in SEGH 2015 and their support to us as organizers. We hope you have enjyoed Bratislava and you are warmly welcome to return to our country.

We hope we can all meet in Brussels for SEGH 2016. See for details.

  • Earthworms and vermicompost: an eco-friendly approach for repaying nature’s debt 2020-01-23


    The steady increase in the world’s population has intensified the need for crop productivity, but the majority of the agricultural practices are associated with adverse effects on the environment. Such undesired environmental outcomes may be mitigated by utilizing biological agents as part of farming practice. The present review article summarizes the analyses of the current status of global agriculture and soil scenarios; a description of the role of earthworms and their products as better biofertilizer; and suggestions for the rejuvenation of such technology despite significant lapses and gaps in research and extension programs. By maintaining a close collaboration with farmers, we have recognized a shift in their attitude and renewed optimism toward nature-based green technology. Based on these relations, it is inferred that the application of earthworm-mediated vermitechnology increases sustainable development by strengthening the underlying economic, social and ecological framework.

  • Plasticizers and bisphenol A in Adyar and Cooum riverine sediments, India: occurrences, sources and risk assessment 2020-01-23


    Adyar and Cooum, the two rivers intersecting Chennai city, are exposed to serious pollution due to the release of large quantities of dumped waste, untreated wastewater and sewage. Sediments can act as repository for emerging organic contaminants. Hence, we have monitored the occurrence and risk associated with plasticizers [six phthalic acid esters (PAEs), bis(2-ethyl hexyl adipate) (DEHA)] and bisphenol A (BPA) in surface riverine sediments of Adyar and Cooum rivers from residential/commercial, industrial and electronic waste recycling sites. Σ7plasticizers (PAEs + DEHA) in the Adyar riverine sediment (ARS) and Cooum riverine sediment (CRS) varied between 51.82–1796 and 28.13–856 ng/g, respectively. More than three-fourth of Σ7plasticizers came from bis(2-ethylhexyl) phthalate (DEHP), in accordance with the high production and usage of this compound. BPA varied between 10.70–2026 and 7.58–1398 ng/g in ARS and CRS, respectively. Average concentrations of plasticizers and BPA were four times higher in electronic waste (e-waste) recycling sites when compared with industrial and residential/commercial sites. BPA and DEHP showed a strong and significant correlation (R2 = 0.7; p < 0.01) in the e-waste sites thereby indicating common source types. Sites present at close proximity to raw sewage pumping stations contributed to 70% of the total BPA observed in this study. For the derived pore water concentration of plasticizers and BPA, the ecotoxicological risk has been found to be higher in ARS over CRS. However, sediment concentrations in all the sites of ARS and CRS were much below the recommended serious risk concentration for human (SRChuman) and serious risk concentration for ecotoxicological (SRCeco).

  • Distribution of metal(loid)s in particle size fraction in urban soil and street dust: influence of population density 2020-01-18


    Assessment of street dust is an invaluable approach for monitoring atmospheric pollution. Little information is available on the size distribution of contaminants in street dusts and urban soils, and it is not known how the population density would influence them. This research was carried out to assess the size distribution of trace metal(loid)s in street dust and urban soil, and to understand how population density might influence the size-resolved concentration of metal(loid)s. Three urban areas with a high, medium and low population density and a natural area were selected and urban soil and street dust sampled. They were fractionated into 8 size fractions: 2000–850, 850–180, 180–106, 106–50, 50–20, 20–10, 10–2, and < 2 µm. The concentration of Pb, Zn, Cu, Cd, Cr, Ni, As, and Fe was determined, and enrichment factor and grain size fraction loadings were computed. The results indicated that the concentration of Pb, Zn, Cu, Cd, and Cr was highly size dependent, particularly for particles < 100 µm, especially for street dust. Low concentrations of Ni and As in street dust and urban soil were size and population density independent. Higher size dependency of the metals concentration and the higher degree of elemental enrichment in the street dust fractions than the urban soils indicate higher contribution of human-induced pollution to the dust. Findings also confirm the inevitability of size fractionation when soils or dusts are environmentally assessed, particularly in moderately to highly polluted areas. Otherwise, higher concentrations of certain pollutants in fine-sized particles might be overlooked leading to inappropriate decisions for environmental remediation.
