Description

Sediment pollution and accumulation in harbours are major environmental issues and studies that advance their solutions are essential for harbour sustainability. This book provides the first comprehensive assessment of chemical pollution in sediments and sediment accumulation rates in the tropical Tema Harbour (Ghana). This book contributes to improving our ability to use an integrated approach involving sediment chemistry and bioassays in one comprehensive assessment of the contamination state of a tropical coastal environment. Whole-sediment toxicity bioassays using the amphipod Corophium volutator and the polychaete Hediste diversicolor as bioindicators were combined with data on concentrations of total metal and metal binding forms, radionuclides, organochlorine pesticides and polycyclic aromatic hydrocarbons in bottom sediments as well as total metal concentrations in settling silt-clay particles collected by sediment traps to characterise the hazard, risk and impact of sediments from the tropical coastal Tema Harbour.

About the Author

Benjamin O. Botwe is an Assistant Lecturer in the Department of Marine and Fisheries Sciences, University of Ghana, where teaches introductory courses in oceanography, limnology, aquatic ecology, marine biogeochemistry and pollution. He holds a Master of Philosophy degree in Chemistry, with a specialization in Analytical/Environmental Chemistry. Currently, he is a PhD fellow at the UNESCO-IHE Institute of Water Education in Delft, The Netherland, where he belongs to the pollution prevention and control chair group. His research interest include coastal/marine pollution and ecotoxicological risk assessment, sediment/pollutant dynamics, metal and organic contaminant biogeochemistry, seafood contamination and human health risks assessment, water quality, environmental radioactivity and ocean acidification. He has several scientific publications including journal articles and book chapters and has participated in scientific conferences and workshops around the world.

About the Series

IHE Delft PhD Thesis Series

IHE Delft PhD programme leads to a deepening of a field of specialisation. PhD fellows do scientific research, often with conclusions that directly influence their region. At IHE Delft, PhD researchers from around the world participate in problem-focused and solution-oriented research on development issues, resulting in an inspiring research environment. PhD fellows work together with other researchers from many countries dealing with topics related to water and the environment.

PhD research is often carried out in the ‘sandwich’ model. Preparation and final reporting – the first and last portion of the programme – are carried out in Delft, while actual research is done in the fellow’s home country, under co-supervision of a local institute. Regular contacts with the promotor are maintained through visits and long-distance communication. This enables researchers to employ solutions directly to problems in their geographical region.

IHE Delft PhD degrees are awarded jointly with a university. The degrees are highly valued and fully recognised in all parts of the world.
