Evaluation of Metallic Trace Elements (MTE) in the sediments of Ouémé delta in Benin

Article in Press

The Metallic Trace Elements (MTE) pollution of aquatic ecosystems and their intrusion and inclusion into the food chain exposes public health to enormous risks. This study assesses the risks associated with the pollution of surface sediments from Ouémé delta with Pb. Cu and Cd. In these sediments stratifications, the physicochemical characteristics of the sediments were evaluated. Total metal contents are determined by...

Climate Change Mitigation Efforts in Ghana

Article in Press

There is a strong correlation between energy, environment and sustainable development. Ideally, a society seeking sustainable development must utilize only energy resources which have little or no environmental impact. Technological changes such as energy savings on the demand side, efficiency improvements in energy production and consumption, and replacement of fossil fuels by renewable energy are the typical strategies...

Evaluation of sustainable use of underground water in peri-urban centers’ of Eldoret Municipality in Kenya

Article in Press

The Kenyan national water quality standard recommends that water should be safe for human consumption. If not protected, ground water can easily be contaminated with many pollutants including biological pathogenic microorganisms. Waterborne diseases can be effectively controlled through proper sanitary procedures that result in use of good quality water through proper sanitary procedures. The main purpose of the study was...

Distribution and Seasonal Variations of Polycyclic Aromatic Hydrocarbons in Sediment of Ala river in Akure Metropolis, Nigeria

Article in Press

This study was carried out to investigate seasonal variations of polycyclic aromatic hydrocarbon (PAHs) in sediments of Ala River, South-west, Nigeria. The total amount of PAHs (∑PAHs) concentration ranged from 4.6 μgg-1to 10.1 μgg-1 dry weights during wet season and from 3.8- 10.3μg.g-1dry weights during the dry season. The total concentrations of PAHs were higher in most of the sites during wet season 80 % and 20 %...
