    Keywords: Volta River Watershed (Ghana) - Environmental condition. ; Electronic books.
    Description / Table of Contents: The Volta River Basin (VRB) is an important transboundary basin in West Africa. Its natural resources sustain the livelihoods of its population and contribute to economic development. This book provides a comprehensive, inter-disciplinary review and assessment of the issues and challenges faced.

    Notes: Abstract Studies were conducted to describe a method for the characterisation of natural and waste waters using plant seed germination as a technique for toxicity testing. Maize seeds were found to be more sensitive to differences in water quality than cowpea seeds and also showed more consistency in results. Trials conducted using natural waters and effluents from gold mining and textile manufacturing operations are also reported.

    Notes: Abstract Data collected over a ten year period have been used to review some characteristics of freshwater and coastal ecosystems in Ghana. Studies were conducted on two recently formed man-made lakes, one river, five coastal lagoons and waters along the ocean front. Freshwaters had near neutral pH while coastal waters were alkaline. In both ecosystems the pH of sediments were lower than those of corresponding waters. While the transparency of coastal waters varied within narrow limits, large variations were observed in freshwaters. The lowest concentration of nutrients occurred in the river and the highest in coastal waters. In general, differences in these physical and chemical characteristics do not depend on whether the aquatic systems were fresh, brackish or saline. They seem to be more influenced by such factors as whether a water body: (1) was lotic or lentic, (2) was influenced by industrial or domestic activities, (3) was affected by impoundment, (4) received turbid water inflows, or (5) was eutrophic.

    Description: Coastal water quality in urban cities is increasingly impacted by human activities such as agricultural runoff, sewage discharges, and poor sanitation. However, environmental factors controlling bacteria abundance remain poorly understood. The study employed multiple indicators to assess ten beach water qualities in Ghana during minor wet seasons. Environmental parameters (e.g. temperature, electrical conductivity, total dissolved solids) were measured in situ using the Horiba multiple parameter probe. Surface water samples were collected to measure total suspended solids, nutrients, and chlorophyll-a via standard methods and bacteria determination through membrane filtration. Environmental parameters measured showed no significant variation for the sample period. However, bacteria loads differ significantly (p = 0.024) among the beaches and influenced significantly by nitrate (55.3%, p = 0.02) and total dissolved solids (17.1%, p = 0.017). The baseline study detected an increased amount of total coliforms and faecal indicator bacteria (Escherichia coli and Enterococcus spp.) in beach waters along the coast of Ghana, suggesting faecal contamination, which can pose health risks. The mean ± standard deviations of bacteria loads in beach water are total coliforms (4.06 × 103 ± 4.16 × 103 CFU/100 mL), E. coli (7.06 × 102 ± 1.72 × 103 CFU/100 mL), and Enterococcus spp. (6.15 × 102 ± 1.75 × 103 CFU/100 mL). Evidence of pollution calls for public awareness to prevent ecological and health-related risks and policy reforms to control coastal water pollution. Future research should focus on identifying the sources of contamination in the tropical Atlantic region.

    Description: Coastal pollution is a worldwide environmental problem. The data provide current status of physico-chemical and microbiological status of Densu estuary, for management controls on environmental pollution. Continuous environmental monitoring is critical to understand ecosystem dynamics and health, for sustainable management of coastal waters.
