Occurrence, quantities and probable human health risks of indicatory polychlorinated biphenyls in processed Lates niloticus (L.) products from Lake Victoria in Tanzania

A study was conducted in Lake Victoria to assess the occurrence, levels and risks of indicator polychlorinated biphenyls (PCBs) in four processed Lates niloticus (L.) products (salted-sundried, trims, smoked and deep-fried). Samples extractions were done using QuEChERS method while detection and quantification of congeners was done using a GC- ECD and GC- MS. Six PCBs (CB 28, CB 52, CB 118, CB 138, CB 153 and CB 180)...

Seasonal variations of some physico-chemical properties of water sources that feed Rivers Wouri and Meme of Cameroon

Rivers Wouri and Meme are surrounded by streams and wells and serve for irrigation, fishing, domestic purposes and transportation. Water samples were collected from the rivers in February (dry season) and August (wet season) of 2012 at different sites and at different depths and analyzed for some physicochemical properties. This was to study the effect of seasonal changes on the properties and also infer the possible...

The roles of community-based water and sanitation management teams (WSMTs) for sustainable development: An example of the Bawku West District, Ghana

Poor sanitation, water and hygiene are related to several and severe negative implications on health and the environment. In recent years, community-based management of water and sanitation facilities have been linked to improving access to these facilities. Ghana is also on its way to achieving the Strategic Development Goals (SDGs) for access to potable water. However, several studies have found gaps between increased...

A chemical speciation study of selected heavy metals in aquatic bottom sediment samples from Mpenge stream, Musanze District, Rwanda

Mpenge stream is regarded as one of the most important domestic water resource in Musanze District; Rwanda. The chemical speciation study of selected heavy metals (Zn, Cu, Co, Cr, Ni, Pb, and Cd) in sediment samples collected from that stream was carried out by means of an analytical procedure involving sequential chemical extraction method and to determine the heavy metals content in different fractions of sediment....
