Master's Thesis from the year 2018 in the subject Environmental Sciences, grade: 76, , language: English, abstract: Rivers are the major sources of water being used in cities and its environs. This water may either be treated or untreated. River banks could be very busy, varied activities ranging from farming to industrial activities and other domestic household activities are conducted. The present study aimed at investigating the potential sources of selected heavy metal contaminants in River Mukurumudzi, Kwale County. Water and sediments were sampled in four points along the river impacted by mining, human settlements and agricultural activities for three different seasons. The samples were analyzed for Iron, Lead, Cadmium, Copper and Arsenic using an AAS. Sediment quality was also analysed by the calculation of CF and I-geo values. Interpretation of results was conducted using Minitab statistical software and Excel spreadsheets. The range of metals in water during the dry season was Fe (0.19-0.32) mg/l, Pb, Cu, Cd and As were below the detection limits. The range of metals in water during the short rain was Fe (0.12-1.25) mg/l and BDL for all other analysed metals. The range of metals in water during the long rain season was Fe (0.07-1.82) mg/l, Cu (0.08-0.11) mg/l and BDL for all the other analysed metals. The range of metals in sediments during dry season was Fe (0.13-1.44) ppm, Pb (0.08-0.54) ppm, and BDL for all other analysed metals. The range of metals in sediments during short rain season was Fe (0.23-1.73) ppm, Pb (0.12-0.27) ppm, and BDL for all other analysed metals. The range of metals in sediments during the long rain season was Fe (0.25-2.75) ppm, Pb (0.09-0.34) ppm, Cu (0.10-0.14) ppm, and BDL for all other analysed metals. The CF values for sediments were all

Written for researchers and practitioners in environmental pollution, management and ecology, this interdisciplinary account explores the ecological issues associated with industrial pollution to provide a complete picture of this important environmental problem from cause to effect to solution. Bringing together diverse viewpoints from academia and environmental agencies and regulators, the contributors cover such topics as biological resources of mining areas, biomonitoring of freshwater and marine ecosystems and risk assessment of contaminated land in order to explore important questions such as: What are the effects of pollutants on functional ecology and ecosystems? Do current monitoring techniques accurately signal the extent of industrial pollution? Does existing policy provide a coherent and practicable approach? Case studies from throughout the world illustrate major themes and provide valuable insights into the positive and negative effects of industrial pollution, the provision of appropriate monitoring schemes and the design of remediation and restoration strategies.

This third edition of the book has been completely re-written, providing a wider scope and enhanced coverage. It covers the general principles of the natural occurrence, pollution sources, chemical analysis, soil chemical behaviour and soil-plant-animal relationships of heavy metals and metalloids, followed by a detailed coverage of 21 individual elements, including: antimony, arsenic, barium, cadmium, chromium, cobalt, copper, gold, lead, manganese, mercury, molybdenum, nickel, selenium, silver, thallium, tin, tungsten, uranium, vanadium and zinc. The book is highly relevant for those involved in environmental science, soil science, geochemistry, agronomy, environmental health, and environmental engineering, including specialists responsible for the management and clean-up of contaminated land.

After decades of regulation and investment to reduce point source water pollution, OECD countries still face water quality challenges (e.g. eutrophication) from diffuse agricultural and urban sources of pollution, that is disperse pollution from surface runoff, soil filtration....

Throughout British history rivers have been of profound economic, social and cultural importance – yet as we see with increasing frequency they have the potential to wreak great destruction. This book describes the natural and not-so-natural changes that have affected British rivers since the last ice age and looks at the many plants and animals that live along, above and within them. Detailed case studies of the Meon, Dee and Endrick illustrate the incredibly varied nature of our river ecosystems, and the natural and human factors that make each one different. Written by two widely respected river ecologists, the book looks not only at rivers as they were and are but also at how they can be managed and cared for. Full of interesting facts and stunning images, Rivers is essential reading for anyone professionally involved in rivers and for the naturalist, conservationist and layman alike. It is the one book you need to understand this singularly important and often contentious feature of the British landscape.
