Join a lively, research focussed network, which values and encourages interdisciplinary work across the spectrum of interactions between humans and the environment.
SEGH has established a series of international conferences and meetings and promotes task force activities to address research and knowledge gaps in the area. SEGH works with other societies and interest groups to further a better understanding of human interaction. SEGH members receive a discount against SEGH conference fees.
SEGH has strong links to training and research projects, with a strong emphasis on encouraging young scientists. Opportunities are developed to enable young researchers to participate in events where experienced professionals from industry and the public sector and academics meet under informal conditions to discuss research findings and relevant gaps in knowledge.
SEGH supports its own cutting edge, impact factor journal: Environmental Geochemistry and Health. In cooperation with Springer, SEGH members can enjoy online access to the journal.
You are warmly invited to join us as returning members or new applicants to the SEGH community.
Full membership: £40, Retired Membership: £22, Student membership: £22
(Both Full, Retired and Student membership with EGH on-line journal access - please note this includes access to the back catalogue)

Secure payments are handled by SagePay and will be charged in £GBP, but you will be billed in your local currency.
Membership runs from January to January. You will need to renew each year using the Join Us button on the homepage and re-enter your details to ensure we have up-to-date information.
Members can keep in touch with their colleagues through short news and events articles of interest to the SEGH community.

Over the past decade, ambient air particulate matter (PM) has been clearly associated with adverse health effects. In Brazil, small and poor communities are exposed to indoor dust derived from both natural sources, identified as blowing soil dust, and anthropogenic particles from mining activities. This study investigates the physicochemical and mineralogical composition of indoor PM10 dust samples collected in Minas Gerais, Brazil, and evaluates its cytotoxicity and inflammatory potential. The mean PM10 mass concentration was 206Â Î¼g/m3. The high dust concentration in the interior of the residences is strongly related to blowing soil dust. The chemical and mineralogical compositions were determined by ICP-OES and XRD, and the most prominent minerals were clays, Fe-oxide, quartz, feldspars, Al(hydr)oxides, zeolites, and anatase, containing the transition metals Fe, Cr, V, Ni, Cu, Zn, Ti, and Mn as well as the metalloid As. The indoor dust samples presented a low water solubility of about 6Â %. In vitro experiments were carried out with human lung alveolar carcinoma cells (A549) to study the toxicological effects. The influence of the PM10 dust samples on cell viability, intracellular formation of reactive oxygen species (ROS), and release of the pro-inflammatory cytokine IL-8 was analysed. The indoor dust showed little effects on alamarBlue reduction indicating unaltered mitochondrial activity. However, significant cell membrane damage, ROS production, and IL-8 release were detected in dependence of dose and time. This study will support the implementation of mitigation actions in the investigated area in Brazil.
The history of uranium mining in Portugal during almost one century has followed international demand peaks of both radium and uranium, which in turn were driven by medical, military, and civil applications. Nowadays, following price drop in the 1980s, mining activities decreased and ceased in 2001. The current challenge is to deal with environmental legacies left by old uranium mines, mainly located in Viseu and Guarda districts. In 2001, based on several radiological surveys carried out, the Portuguese government assumed the remediation costs of abandoned mine areas for environmental safety and public health protection. Detailed environmental and public health risk assessments were performed under the scope of studies both requested by the government and by funded research projects. It was found that the existing risks, due to radiological and chemical exposures to metals and radionuclideâ€™s, were particularly high at the old milling facilities and mines where in situ and heap leaching of low-grade ore occurred. The different studies, involving both humans and non-human species from different trophic levels, demonstrated the existence of effects at different levels of biological organization (molecular, cellular, tissues, individuals, and populations) and on ecosystem services. To mitigate the risks, the environmental rehabilitation works at the UrgeiriÃ§a mine complex are almost complete, while at Cunha Baixa mine, they are presently in progress. These works and environmental improvements achieved and expected are described herein.
