Microbiological characteristics of waters in the major rivers in Kainji Lake National Park

  This research work determined the microbiological characteristics of the waters of rivers of Kainji Lake National Park. The implications on public health and aquatic life were also examined. The rivers include: Oli, Manyera, Poto and Nuwanzurugi. Samples were taken twice a year, that is, dry and wet seasons of each year.  Standard methods were used for bacteriological examination plating. The results...

Assessment of contamination of singed hides from cattle and goats by heavy metals in Ghana

  Many local butchers in Ghana have been using scrap tyres as substitute for firewood to singe slaughtered ruminants. This study analysed such singed hides from seven goats and three cattle in unregulated local slaughtering operations near the Kumasi abattoir, for risk of heavy metal contamination (Mg, Mn, Cu, Ni, Cd, Pb and Zn) using atomic absorption spectrometry. Relative to un-singed control hides, singed...

Range use and dynamics in the agropastoral system of southeastern Kenya

  Occurrence of equilibrium and non equilibrium system dynamics in semiarid environments present serious management challenges. In these areas, resource management strategies are increasingly based on equilibrium rather than non equilibrium dynamics that assume simple system dynamics and strong coupling of animal-plant responses. This management approach underlies increasing trends of range degradation and low...

Survey of the physico-chemical quality of the wastewaters of Biskra city rejected in Chabat Roba, Messdour and Wadi Z'ommor (Algeria)

  The wastewaters of the agglomeration of Biskra (Southeast Algeria) are poured without treatment in three main dismissals that are Chabat Roba (1st site), Messdour (2nd site) and Wadi Z'ommor (3rd site). The pollution charge determined in the 1st site is the order of 157.76 ± 34.14 mg/L of O2 for the BOD5(Biochemical Oxygen Demand in 5 days) of 457 ± 73.59 mg/L of...
