Abstract: Heavy metal pollution has been considered to be an ecological threat to man and other organisms especially when found in organs above the threshed concentrations. Elechi creek is a major source of water for domestic and industrial use. The concentration of heavy metals such as Cadmium (Cd), Chromium (Cr), lead (Pb) and Copper (Cu) in water and sediment were investigated using Atomic Absorption Spectrophotomer. The mean concentrations (mg/l) in water were respectively, Cd(0.0036 + 0.277), Cr (0.0042 + 0.196), Pb(0.00387 + 0.136) and Cu(0.0068 + 0.217) while that of sediment(mg/kg) were Cd(0.00494±0.203), Cr (0.00457 + 0.172), Pb(0.00468 + 0.205) and Cu(0.00731 + 0.204)) respectively. Apart from Cd which exceeded the TSE – 266 and WPCC limit and Pb which exceeded..........

Abstract: Periyar is the longest river in Kerala state. The river overflowed during August 2018 due heavy rainfall and releasing of water from the reservoir of Mullaperiayar Dam. This resulted in flood along the bank of the river and also extended to the nearby areas.Thus it was essential to monitor the quality of the river in order to ensure quality water for domestic and agricultural purposes. The aim of the study was to assess some physico-chemical parameters of river Periyar and present the Water Quality data of the river before and after flood. The Canadian Council of Ministry of Environment Water Quality Index(CCMEWQI)was applied on the analytical result of the parameters to obtain the Water Quality Index which in turn is used to rank the river. The result of the average Water Quality.......

Abstract: This study comparatively assessed the bioaccumulation of some PAHs and heavy metals by catfish harvested from rivers, swamp and commercial fish ponds in oil polluted and non-oil polluted areas. Three fishes were collected from each of the following sites; Akaraolu swamps in Ahoada East LGA (AR), a commercial fish pond within the area (AP), The New Calabar River in Ikwerre LGA (BR), a fish pond within the area (BP), Omambala River, Anambra East LGA (CR), a fish pond in Awka, Anambra state (CP), six groups in all. All analyses were done following standard procedures. Following analysis, there was no significant difference in the PAHs concentration for all sites. The Ni Pb, and Cr values were greater than the WHO limits (0.5, 0.4 and 1.0mg/kg respectively), their concentrations were in this order; CR˃BR˃AR (Ni and Cr), CR˃AR˃BR (Pb), and was the same for the ponds. Zn concentrations.........

Abstract: The main objective of this study was to investigate the factors affecting sustainability of mini-grid energy in Kenyan rural areas: A Case of Kisii County. The specific objectives were to establish the influence of energy policy /framework advisory, implementation mechanism and capacity building/training on sustainability of mini- grid energy within rural areas in Kisii County. A descriptive research design was used in this study. The study targeted 110 personnel in various departments of the energy service companies and 600 customers connected to mini – grid energy operators particularly those operating within Kisii County as they were better placed to answer questions relating to factors affecting sustainability of mini- grid energy within rural areas in Kisii County.
