A hidden opportunity: Collaborative Development of teaching and learning in Environmental Geochemistry and Health at the Department of Geology, University of Calabar, Nigeria


The topic of Environmental Geochemistry has existed as a postgraduate course of study in the Department of Geology, University of Calabar in Nigeria for the past eighteen years. After my Commonwealth Academic Fellowship in 2008-2009, hosted by Prof A.S Hursthouse at the School of Science, University of the West of Scotland, I became a member of SEGH. The skills acquired during this period and as a registered member of SEGH, we decided to review the existing environmental geochemistry curriculum during my tenure as the Head of Department in 2012, since being established in 1976, its first female to hold that post.


Through my colleagues in SEGH, I was able to consult widely with members of the International SEGH board to review and gather opinion on the programme topics and syllabus content. This exercise was of great help and a real benefit to get feedback from the environmental geochemistry and health community, giving a real international perspective. It has helped to provide a good justification for changes to the programme in discussion with our University. The course was approved as an area of specialization under Environmental Geoscience section starting from 2013/2014 session. It is among the courses currently being advertised by the graduate school for this session and it will be in cooperated into the new graduate school brochure of the University to help to give it a wider publicity. It is anticipated that in future this will be extended to the undergraduate level when the curriculum will be reviewed as well.

We also hope that with further support from the members of SEGH we will be able to carry out some collaborative research where we lack the necessary laboratory facilities and some graduate students will be able to benefit from the expertise of SEGH members as the need arises.

At this juncture, I would like to thank members of SEGH for their input in structuring of the curriculum.

  • Status, source identification, and health risks of potentially toxic element concentrations in road dust in a medium-sized city in a developing country 2017-09-19


    This study aims to determine the status of potentially toxic element concentrations of road dust in a medium-sized city (Rawang, Malaysia). This study adopts source identification via enrichment factor, Pearson correlation analysis, and Fourier spectral analysis to identify sources of potentially toxic element concentrations in road dust in Rawang City, Malaysia. Health risk assessment was conducted to determine potential health risks (carcinogenic and non-carcinogenic risks) among adults and children via multiple pathways (i.e., ingestion, dermal contact, and inhalation). Mean of potentially toxic element concentrations were found in the order of Pb > Zn > Cr(IV) > Cu > Ni > Cd > As > Co. Source identification revealed that Cu, Cd, Pb, Zn, Ni, and Cr(IV) are associated with anthropogenic sources in industrial and highly populated areas in northern and southern Rawang, cement factories in southern Rawang, as well as the rapid development and population growth in northwestern Rawang, which have resulted in high traffic congestion. Cobalt, Fe, and As are related to geological background and lithologies in Rawang. Pathway orders for both carcinogenic and non-carcinogenic risks are ingestion, dermal contact, and inhalation, involving adults and children. Non-carcinogenic health risks in adults were attributed to Cr(IV), Pb, and Cd, whereas Cu, Cd, Cr(IV), Pb, and Zn were found to have non-carcinogenic health risks for children. Cd, Cr(IV), Pb, and As may induce carcinogenic risks in adults and children, and the total lifetime cancer risk values exceeded incremental lifetime.

  • In vivo uptake of iodine from a Fucus serratus Linnaeus seaweed bath: does volatile iodine contribute? 2017-09-02


    Seaweed baths containing Fucus serratus Linnaeus are a rich source of iodine which has the potential to increase the urinary iodide concentration (UIC) of the bather. In this study, the range of total iodine concentration in seawater (22–105 µg L−1) and seaweed baths (808–13,734 µg L−1) was measured over 1 year. The seasonal trend shows minimum levels in summer (May–July) and maximum in winter (November–January). The bathwater pH was found to be acidic, average pH 5.9 ± 0.3. An in vivo study with 30 volunteers was undertaken to measure the UIC of 15 bathers immersed in the bath and 15 non-bathers sitting adjacent to the bath. Their UIC was analysed pre- and post-seaweed bath and corrected for creatinine concentration. The corrected UIC of the population shows an increase following the seaweed bath from a pre-treatment median of 76 µg L−1 to a post-treatment median of 95 µg L−1. The pre-treatment UIC for both groups did not indicate significant difference (p = 0.479); however, the post-treatment UIC for both did (p = 0.015) where the median bather test UIC was 86 µg L−1 and the non-bather UIC test was 105 µg L−1. Results indicate the bath has the potential to increase the UIC by a significant amount and that inhalation of volatile iodine is a more significant contributor to UIC than previously documented.
