The conference will take place at the conference facilities of The Business School at Manchester Metropolitan University, Manchester UK between 1 and 5 July 2019.

This annual conference provides a forum for international scientists, consultants, regulatory authorities and other practitioners to debate the current-day environmental challenges. The conference will focus on the links between environmental health and the broad area of environmental geochemistry and will broadly follow the following themes:

Urban and industrial sustainable development

Environmental Pollution & Change

New technologies

Monitoring the environment

Environmental Health

Sustainable nutrition and agriculture

In addition to the presentations (posters and orals), exhibitions and academic debates, an exciting social programme is planned, including visits to and events at iconic places of interest in Manchester. The formal dinner will be at the Midlands Hotel (https://themidlandhotel.co.uk/) and an interactive session on sustainable nutrition (MetMUnch http://metmunch.com/) will precede a pub-crawl. Please watch this space for more information.

Interested in presenting at our conference?

Submissions should be written from a strong technical background and should clearly demonstrate a familiarity with the related work and field. Further information can be found on https://www2.mmu.ac.uk/segh-19/ 

 

Interested in EXHIBITING at / SPONSORING our conference?

 The organising committee invites you to participate as a cooperate sponsor to ensure your visibility at this prestigious conference and to provide an excellent opportunity to network and market your company/agency. Please find further information here: https://www2.mmu.ac.uk/segh-19/ OR contact the SEGH 2019 chair at s.potgieter@mmu.ac.uk  

Additional information (accommodation, travelling to the conference, registrations options and fees, etc.) will be available shortly via our website, with registration opening in the autumn.

We look forward to welcoming you to Manchester, UK.

  • Membrane fouling control by Ca 2+ during coagulation–ultrafiltration process for algal-rich water treatment 2019-04-16

    Abstract

    Seasonal algal bloom, a water supply issue worldwide, can be efficiently solved by membrane technology. However, membranes typically suffer from serious fouling, which hinders the wide application of this technology. In this study, the feasibility of adding Ca2+ to control membrane fouling in coagulation–membrane treatment of algal-rich water was investigated. According to the results obtained, the normalized membrane flux decreased by a lower extent upon increasing the concentration of Ca2+ from 0 to 10 mmol/L. Simultaneously, the floc particle size increased significantly with the concentration of Ca2+, which leads to a lower hydraulic resistance. The coagulation performance is also enhanced with the concentration of Ca2+, inducing a slight osmotic pressure-induced resistance. The formation of Ca2+ coagulation flocs resulted in a looser, thin, and permeable cake layer on the membrane surface. This cake layer rejected organic pollutants and could be easily removed by physical and chemical cleaning treatments, as revealed by scanning electron microscopy images. The hydraulic irreversible membrane resistance was significantly reduced upon addition of Ca2+. All these findings suggest that the addition of Ca2+ may provide a simple-operation, cost-effective, and environmentally friendly technology for controlling membrane fouling during coagulation–membrane process for algal-rich water treatment.

  • Evaluation of the raw water quality: physicochemical and toxicological approaches 2019-04-13

    Abstract

    Environmental degradation has increased, mainly as a result of anthropogenic effects arising from population, industrial and agricultural growth. Water pollution is a problem that affects health, safety and welfare of the whole biota which shares the same environment. In Goiânia and metropolitan region, the main water body is the Meia Ponte River that is used for the abstraction of water, disposal of treated wastewater and effluents. In addition, this river receives wastewater from urban and rural areas. The aim in this present study was to evaluate the quality of raw water by some physical, chemical and toxicological tests. The physicochemical results found high levels of turbidity, conductivity, aluminum, phosphorus and metal iron, manganese, copper and lithium when compared to the standards of the Brazilian legislation. The values found of toxicity demonstrated a high degree of cytotoxicity and genotoxicity. Therefore, it was concluded that the Meia Ponte River has been undergoing constant environmental degradation, causing the poor quality of its waters. Thus, measures for the prevention and recovery should be adopted for the maintenance of the Meia Ponte River.

  • Review of the nature of some geophagic materials and their potential health effects on pregnant women: some examples from Africa 2019-04-11

    Abstract

    The voluntary human consumption of soil known as geophagy is a global practice and deep-rooted in many African cultures. The nature of geophagic material varies widely from the types to the composition. Generally, clay and termite mound soils are the main materials consumed by geophagists. Several studies revealed that gestating women across the world consume more soil than other groups for numerous motives. These motivations are related to medicinal, cultural and nutrients supplementation. Although geophagy in pregnancy (GiP) is a universal dynamic habit, the highest prevalence has been reported in African countries such as Kenya, Ghana, Rwanda, Nigeria, Tanzania, and South Africa. Geophagy can be both beneficial and detrimental. Its health effects depend on the amount and composition of the ingested soils, which is subjective to the geology and soil formation processes. In most cases, the negative health effects concomitant with the practice of geophagy eclipse the positive effects. Therefore, knowledge about the nature of geophagic material and the health effects that might arise from their consumption is important.
