Influence of particle size and total organic carbon on heavy metal concentrations in sediments of Lake Baringo, Kenya

Heavy metals impair water and sediment quality and thus, can cause adverse impacts on aquatic organisms especially when they exceed the recommended threshold levels. Heavy metal concentrations in water and sediments are a reflection of the anthropogenic activities on the watershed as well as the geology of the area. Metal concentrations and subsequently their bioavailability are influenced by the sediment...

Spatio-temporal characterization of the physico-chemical quality of groundwater: Case of the Lobo watershed (Centre-west of Côte d'Ivoire)

Drinking water supply to rural communities is increasingly relying on finding groundwater. However, groundwater resources, although believed to be safe and free of pollution, are subjects to local and diffusive pollution. This work aims at assessing the groundwater quality in the Lobo catchment area in Nibéhibé and addressing the mineralization phenomena. To achieve such an objective, a statistical...

Mining the past for a better future of African waters: Historical changes in the fish and fishery of Lake Bam (Burkina Faso) before rehabilitation

Terrestrial waters provide multiple goods and services to human kind, but they have been severely diminished by increasing human exploitation of water and the landscapes surrounding aquatic communities. This research illuminates such dynamics in the recent history of exploitation of the Lake Bam fishery in Burkina Faso. To do so, from 2009 to 2015 we collected data on the ecology, exploitation and governance of the Lake...

Residents’ perception of the effects of soot pollution in Rivers State, Nigeria

Air pollution is a growing cause of morbidity and mortality globally. Nigeria is confronted with rising air pollution concerns due to activities of extractives, industrialisation and high population growth rate. Many areas of Rivers State, which provide 60% of Nigeria’s crude oil output, have recently been experiencing visible fallout of soot. To assess the perception of residents of Rivers State on the current...
