SEGH celebrated its 50th anniversary in 2021; a special issue of Environmental Geochemistry & Health marked this event. We now look forward to the next 50 years. In 2022 we welcomed our new president. As we emerge from a global health crisis, and with conflict, economic insecurity and climate change clouding our horizons, the activities of SEGH were never more relevant. Our Fellows provide a core to SEGH. This status is awarded by the SEGH board to individuals who have made significant personal contributions to the promotion of the Society. Many have served as board members, Chair, hosted SEGH conferences and many other areas of contribution. They are also recognised for their contribution to the scientific knowledge base across the SEGH landscape and advancing understanding of the interaction between the environment and human health.
In 2022 we are launching a series of SEGH Live (online) presentations by SEGH Fellows which will share experience and knowledge and strive to transfer the ethos of the collaborative nature of our group.
The sessions will be invaluable to Early Career Researchers but also enable each of us to step into areas of expertise of other members of the society, which has a very broad reach.
These 35 minute presentations, with a 15 minute Q&A, will be held approximately monthly. The time of day is intended to enable as many people across the global time zones to attend as possible. However, for those unable to attend a live session, the recordings will be available to access after the event via the website.
Please refer to the website on a regular basis to see what has been added to the schedule.
Snippets from Nigeria: Evolution and State of the Science of Environmental Geochemistry and Health
Akinade Olatunji
Professor of Applied Geochemistry, University of Ibadan
Nigeria is the most populous country on the African continent with an estimated population of over 242 million people as of 2026. The Nigerian nation is endowed with huge natural resource and as the population grows, so does urbanisation and industrialisation, which most times are unplanned. These unplanned developmental activities have their negative effects on environmental media, and the consequences of these negative impacts are being felt in the type of prevailing health and medical cases that are now being reported in the country. The environmental geochemists and several environmentalists have been studying the impacts of these unplanned developments on the quality of environmental media such as soils, stream sediments, rivers, road dusts and particulate matter. The efforts of these professional scientists have evolved over the year from fringe scientific endeavour to mainstream scientific actions that have ultimately led to introduction of several government policies and agencies charged with responsibilities to ensure that environmental quality standards are maintained and regulated as the triple helix of population growth, urbanisation and industrialisation drive the economic growth of the Nigerian nation.

Olatunji Akinade is a Professor of Applied and Environmental Geochemistry at the Department of Geology, University of Ibadan, Ibadan, Nigeria. He is one of the renown experts in environmental geochemistry and health research in Nigeria. He and his team at the University of Ibadan are leadinghad undertakenresearch in urban geochemistry in Nigeria producing very well researched scientific publications in the process. Prof Olatunji and his team have undertaken urban geochemical mapping of major cities in Nigeria including Lagos, Abuja, Benin, Ibadan, Sagamu, Ijebu Ode among several others. These studies have produced baseline geochemical data for these cities and have been used to identify pollution hotspots in such cities thus providing scientific basis for deploying appropriate remediation mechanisms. Prof Olatunji is the immediate past president of the Nigerian Mining and Geosciences Society (NMGS), a past president of the Society for Environmental Geochemistry and Health and the Nigerian Leader of the International medical Geology Association (IMGA). He is a Fellow of the NMGS, SEGH, NAH, IAH, NAEGE, NSEG and NSME. Prof Olatunji has supervised fifteen completed Doctoral Theses and several M.Sc. Dissertations; He is also as associate editor to several reputable journals.
