Mosquito control has been a point of focus in scientific communities, especially health-providing units. Various methods have been tried and many more still being developed to eliminate or reduce mosquito populace. Certain environmental issues related with chemical control of mosquitoes have convinced experts to opt for eco-friendly methods. Among those methods are the biological control methods, which suppress vector populations through introduction/manipulation of organisms (natural enemies, e.g., parasites, disease organisms and predatory animals). Present study was focused on using edible fish as predator of mosquito larvae. Experimental results revealed that, edible fish have tremendous potential to be used as larvivorous predator of mosquito. It was further found that, larvivorous fish (Gambusia Affinis), used in this study preferred live larvae when compared with commercial food. The rate of consumption was between 180 to 190 larvae per fish per day, and fish preferred live larvae (65.72%) over dead larval stuff (37.14%). Another aim of the study was to determine the effect of light and dark periods on larvae consumption and it revealed that 88.75% of larvae were eaten in the presence of light and only 51.25% in dark by the mosquito fish. In micro-field condition, out of 500 larvae, only 13 (2.6 %) larvae were left, whereas rest of the larvae were consumed by the fish. The study suggests the larvivorous fish to be tried as biological control agent for mosquitoes.

Soils produce 95 percent of the food we consume, healthy soil provides crucial ecosystem services for life, such as water storage, purification and flood regulation, carbon sequestration and consequently climate change mitigation, or nutrient cycling e.t.c. The dangers posed to the environment due to anthropogenic activities necessitate the need for novel strategies for decontamination and clean up. It is challenging to realize and discover the interplay between the biodiversity in polluted environments. The process of clean-up can be done in aerobic or anaerobic systems depending on the microorganisms and the electron acceptors available in the media. This review has examined the sources of pollutants into the environment, mechanism for clean-up, contribution of molecular techniques and how utilization of biodiversity can be an effective technique available for clean-up of polluted sites. Though the idea has a long history, however other relatively new applications are emerging or being developed for optimization of the existing biodiversity - based techniques for clean-up of polluted environments.

Bauxite dust is widely used in the production of high-quality bauxite due to its high Al?O? content. This bauxite residue was recovered from the dryer hoppers during the drying of bauxite at Department 42 of the Compagnie des Bauxites de Guinée. The dust and gas that have escaped from the cyclones are washed down by water jets from the scrubber, whilst the slurry is discharged into the settling ponds via two pumps into the East and West ponds. The slurry is then conveyed to the drying beds by dredging, where it is dried during the dry season and transported to the storage site. This study aims to further our understanding of the use of bauxite dust from the Compagnie des Bauxites de Guinée (CBG) in the bauxite industry, with a view to recycling bauxite residues. The initial raw samples were characterised using X-ray fluorescence spectroscopy (XRF). The quantity of bauxite to be exported is estimated at 26,042,000 tonnes, with a moisture content of 6.7 per cent. This figure varies depending on the provisional quantity. The results obtained demonstrate environmental potential for the production of high-quality alumina.
