Adewole Michael Gbadebo a Professor of Environmental Geochemistry at the Department of Environmental Management and Toxicology, Federal University of Agriculture, Abeokuta, Nigeria shares his experience of SEGH2019

I arrived at Manchester Metropolitan University (MMU), venue of the 35th SEGH conference at around 4 pm on Monday 1st July 2019  where  I was welcomed by Prof. Sanja Potgieter-Vermaak. On the morning of  Tuesday 2nd July 2019, I came to the venue of the conference from my hotel registered for the conference, mounted my poster on the assigned billboard, attended the welcome and introduction section and attended the day’s sessions (comprising of morning and afternoon sessions). Each session started with keynote speakers’ presentation followed by 15 minutes of Platform /Oral presentations and 2-minute flash presentations with an interlude of lunch break before the afternoon section. I was at my poster stand during the break periods to present my work to poster viewing conference-participating-audience. This I did routinely from Tuesday 2nd – Thursday 4th July 2019.

I also attended behind the scenes evening social at the Manchester City Football Stadium on the evening of Tuesday 2nd. I remember hearing Prof Sanja Potgieter-Vermaak mention that participants at the conference were from 15 countries of the world including Nigeria. At the end of the conference, during the closing ceremony/remarks, hosts of the 36th and 37th SEGH in Kenya and China were announced and acceptance speeches were given by Prof Odipo Osano from Kenya and China representatives. Prizes were given to the best poster presenter and people who worked with Prof Sanja Potgieter-Vermaak to make the conference a huge success. This was capped with SEGH AGM which took place on Thursday at the same venue of the conference with the delegates (conference participants) in attendance and Dr Michael Watts from BGS was re-elected as the chair of SEGH.

With regards to networking opportunities, the conference afforded me opportunities for meeting professional colleagues from diverse institutions and fields of specialization and interests. I was able to discuss with these scientists, possibilities of research collaborations. Some of these people include but not limited to: Michael Watts (BGS); David Manning (on carbon-capturing); Ricardo Godoi (on Pollen & Hospitality); Paul Preton (on Brownfield Sciences); Khadija and Jane (on Household Dust); Alex Stewart (on Iodine Diseases in Nigeria, Nee Africa).

I am grateful for the SEGH bursary I received as an international participant from a developing country.

  • Agro-ecological suitability assessment of Chinese Medicinal Yam under future climate change 2019-10-15

    Abstract

    Chinese Medicinal Yam (CMY) has been prescribed as medicinal food for thousand years in China by Traditional Chinese Medicine (TCM) practitioners. Its medical benefits include nourishing the stomach and spleen to improve digestion, replenishing lung and kidney, etc., according to the TCM literature. As living standard rises and public health awareness improves in recent years, the potential medicinal benefits of CMY have attracted increasing attention in China. It has been found that the observed climate change in last several decades, together with the change in economic structure, has driven significant shift in the pattern of the traditional CMY planting areas. To identify suitable planting area for CMY in the near future is critical for ensuring the quality and supply quantity of CMY, guiding the layout of CMY industry, and safeguarding the sustainable development of CMY resources for public health. In this study, we first collect 30-year records of CMY varieties and their corresponding phenology and agro-meteorological observations. We then consolidate these data and use them to enrich and update the eco-physiological parameters of CMY in the agro-ecological zone (AEZ) model. The updated CMY varieties and AEZ model are validated using the historical planting area and production under observed climate conditions. After the successful validation, we use the updated AEZ model to simulate the potential yield of CMY and identify the suitable planting regions under future climate projections in China. This study shows that regions with high ecological similarity to the genuine and core producing areas of CMY mainly distribute in eastern Henan, southeastern Hebei, and western Shandong. The climate suitability of these areas will be improved due to global warming in the next 50 years, and therefore, they will continue to be the most suitable CMY planting regions.

  • Application of stable isotopes and dissolved ions for monitoring landfill leachate contamination 2019-10-15

    Abstract

    We evaluated groundwater contamination by landfill leachate at a municipal landfill and characterized isotopic and hydrogeochemical evidence of the degradation and natural attenuation of buried organic matter at the study site. Dissolved ion content was generally much higher in the leachate than in the surrounding groundwater. The leachate was characterized by highly elevated bicarbonate and ammonium levels and a lack of nitrate and sulfate, indicating generation under anoxic conditions. Leachate δD and δ13CDIC values were much higher than those of the surrounding groundwater; some groundwater samples near the landfill showed a significant contamination by the leachate plume. Hydrochemical characteristics of the groundwater suggest that aquifer geology in the study area plays a key role in controlling the natural attenuation of leachate plumes in this oxygen-limited environment.

  • Lead transfer into the vegetation layer growing naturally in a Pb-contaminated site 2019-10-10

    Abstract

    The lead was one of the main elements in the glazes used to colour ceramic tiles. Due to its presence, ceramic sludge has been a source of environmental pollution since this dangerous waste has been often spread into the soil without any measures of pollution control. These contaminated sites are often located close to industrial sites in the peri-urban areas, thus representing a considerable hazard to the human and ecosystem health. In this study, we investigated the lead transfer into the vegetation layer (Phragmites australis, Salix alba and Sambucus nigra) growing naturally along a Pb-contaminated ditch bank. The analysis showed a different lead accumulation among the species and their plant tissues. Salix trees were not affected by the Pb contamination, possibly because their roots mainly develop below the contaminated deposit. Differently, Sambucus accumulated high concentrations of lead in all plant tissues and fruits, representing a potential source of biomagnification. Phragmites accumulated large amounts of lead in the rhizomes and, considering its homogeneous distribution on the site, was used to map the contamination. Analysing the Pb concentration within plant tissues, we got at the same time information about the spread, the history of the contamination and the relative risks. Finally, we discussed the role of natural recolonizing plants for the soil pollution mitigation and their capacity on decreasing soil erosion and water run-off.
