This study was an attempt to understand the factors influencing the heavy metal distribution in polluted fluvial system sediments. Various biogeochemical processes and anthropogenic factors were playing an important role in altering the concentration of heavy metals in the sediments. This paper has two objectives : the first one is to investigate the effect of the variation in the physicochemical conditions on the speciation of trace elements trapped in the sediments of the Sebou River. The second one is to study the kinetics mobilization of these heavy metals. Batch resuspension experiments were conducted in order to investigate the release of heavy metals from a polluted anoxic sediment submitted to different physicochemical conditions variations. It has been revealed that in oxygenated environment, sediments were oxidized which cause the release of some heavy metals, but their concentrations, as dissolved phase, were sustained constant or were increased with time. However, in acidic and anaerobic environment, most of the metallic trace elements were released together with the iron and the manganese, but some of these elements like chromium were precipitated. However, some of other elements were maintained in solution, which represents a real human health risk. [less ▲]

In forms dissolved and/or fixed at the particles the metal elements traces can accumulate in the sedimentary zones and constitute important stocks of pollutants. These contaminants can be remaining in the dissolved phase and become biodisponible under the effect of the physicochemical conditions and could act as a long-term source of pollution. To understand the mobility and the reactivity of these stocks is an important issue for the management of the quality of the hydrosystèmes. The exchangeable or unstable fraction of the sediment corresponds to the metal ions being adsorbed on the surface of the particles constituting the sediment (clays, oxide iron…), or mobility and the biodisponibility are high in this fraction because of the weak electrostatic interactions. The goal of this study and to characterize the sediments of Sebou and Fès Rivers and to evaluate the risk of toxicity of the elements metal traces related to the particulate phase by the method of spared digestion. Metals in these fractions are assumed to be more available than metals associated with residual fractions. The results obtained show a strong mobilization of the elements related to the unstable fraction which reaches 100% for Pb and 70% for Cr. The sediments are composed of two mineralogical phases and they are also very rich in organic matter. [less ▲]

Assessing the parasite loads in rivers crossing cities is important for identifying the potential risks for humans and livestocks, and for selecting suitable risk reduction measures. The aim of this study was to determine parasite loads in four rivers (Bwindi, Kahwa, Tshula, and Wesha) crossing the city of Bukavu and flowing to the Lake Kivu. For each of the rivers data were collected at points located upstream of the lake embouchure during 2013-2014, and analysed through a modified Bailenger method. Our results showed that all the rivers were characterized by a rather high TDS content, an alkalinity above 7.7 and temperatures above 22°C, on average. Moreover, a diversity of parasites including nematodes, cestodes, protozoa and trematodes, was observed: Entamoeba coli, Ascaris sp., Hymenolepis diminuta, Taenia saginata, Giardia lamblia, Ankylostoma sp., Strongyloides stercoralis, Schistosoma mansoni, Entomoeba histolytica, Hymenolepis nana, and Trichuris trichura. Nematodes represented the most common parasites in Kahwa, Tshula and Wesha rivers (57% to 71% of species recorded), while cestodes were predominant in Bwindi river (77% of species recorded). Additionally, high parasite loads were observed during the rainy season. The results highlight the health risks to people who use water from these rivers for various needs (bathing, irrigation, dishes, and laundry). The use of the modified method of Bailenger would be of great interest for the characterization of urban waste waters and the promotion of public health because of the simplicity of its implementation and its low cost.
