ABSTRACT: In present study, surveys was conducted and costs was calculated to determine the daily stretch of time the village is provided with electrical energy: from 6 pm to 10 pm; and to select a bio-fuel operated generator with a 30 kVA output. The plantation of 0.5 hectare of Jatropha curcas by each household would be enough to cover the expenses in electricity consumption if the grains are sold at 50 CFA F/kg. Electrification would contribute to reduce rural exodus and promote trade. The plant cover of Terahoe will be enriched in Jatropha curcas, thus creating biological diversity that will protect food crops.

ABSTRACT: Seasonal variations in physico-chemical and bacterial characteristics of samples from Ogodogbo creek were investigated during the dry and rainy seasons. Higher physico-chemical parameters occurred in the rainy season than in the dry season but higher salinity was observed in the dry season. More bacterial genera (12) were isolated during the rainy season compared with nine genera during the dry season. Bacillus spp. was the most prevalent (32- 39%) during the two seasons but Vibrio spp was the most dominant (31%) in the dry season. This study has shown that this creek is suitable for cultivation of mangrove oysters (Crassostrea gasar). However, the isolation of some pathogens suggests public health hazards if the sea foods from this resource are not adequately processed before consumption.

ABSTRACT: Organic compounds decompose under anaerobic condition to yield biogas. This research work shows the result of biogas produced from Cow dung, Poultry waste and Yam peels. It has been observed that the highest production rate was recorded for Cow dung (496ml), Poultry waste (347ml) and Yam peels (337ml) respectively at the 8th week. While the pH of production ranged from 7.72 to 6.63. The percentage moisture content for Cow dung, Poultry waste and Yam peels before and after production are 83.5, 13.9, 47 and 69.3, 9.2, 35.1 respectively. The ash contents before and after production are 30.4%, 35.2%, 12.9% and 28.8%, 33% and 8.5% respectively. This shows that biogas production depends on the nature of substrate and also blending Cow dung, Poultry waste and Yam peels alone are good materials for biogas production at a reasonable pH and moisture content value.

ABSTRACT: Chromium is a heavy metal, and considered as an environmental hazard. Toxicity effects of chromium on growth and development of plants including inhibition of germination process, and decrease of growth and biomass of plant. The aim of this research is to study accumulation of chromium along with nutrients and its effect on the growth of paddy plant (Oryza sativa L.). Thus, paddy seedlings grown in petriplates lined with filter paper undergoing, different treatments of Cr (0, 2.5, 5, 10, 25, 50, 75, 100 and 200 mg/L). After one week seedlings were removed and morpho physiological parameters like root length, shoot length and dry weight of plants and accumulation of nutrients along with Cr in roots and shoots were determined. The results indicated that the concentrations more than 100 mg/L chromium cause the reduction of morphophysiology parameters in the treatment plants rather than control plant and Cr addition in the cultures caused enhancement of chromium content in roots and shoots of plant seedlings. Similarly nutrient accumulation was also affected by increasing concentrations of chromium. It was also noted that accumulation of chromium in the roots was much higher than the shoots of the seedlings under treatment.

ABSTRACT: The concentrations of chromium, cadmium, copper and lead were determined in gills and muscles of catfish (Clarias garipienus) obtained from Dukku River in Kebbi State of Nigeria using atomic absorption spectrophotometer. The mean concentration of heavy metals in gills and muscles were Cd (0.167±0.029 and 0.133±0.058), Pb (8.433±4.032 and 9.570±3.286), Cr (0.500±0.259 and 0.284±0.076) and Cu (0.417±0.189 and 0.350±0.150), respectively. The order of decreasing heavy metal concentrations in the gills and muscles were Pd > Cr > Cu > Cd and Pb > Cu > Cr > Cd, respectively. With the exception of Pb, gills were found to have higher concentrations of all the heavy metals analyzed. Hence, it could be concluded that the fish (catfish) in Dukku River was polluted with Pb.

ABSTRACT: The collection, transport, treatment, and disposal of solid wastes, particularly wastes generated in medium and large urban centers, have become a relatively difficult problem to solve for those responsible for their management. The problem is even more acute in economically developing countries, where financial, human, and other critical resources are generally scarce. The present study was conducted to know the quantity of solid waste in seven wards of Bhopal district. An attempt has been made in this study to know the quantity of solid waste in seven wards of the city. People’s awareness about solid waste management has also been addressed.
