Effect of leaching on heavy metals concentration of soil in some dumpsites

Study on the effect of leaching on heavy metals concentration at dumpsites was conducted by analyzing samples of soil collected from different dumpsites located within Ikere and Ado Ekiti metropolis, South Western Nigeria. The samples were analyzed for concentrations of Cd, Co, Cr, Cu, Fe, Pb, Mn, Ni, Sn and Zn. Control soil samples were taken at 200 m away from the last sampling point on each dump site down the slope...

Effects of temporal changes in climate variables on crop production in tropical sub-humid South-western Nigeria

  Climate variability and change have been implicated to have significant impacts on global and regional food production particularly the common stable food crops performance in tropical sub-humid climatic zone. However, the extent and nature of these impacts still remain uncertain. In this study, records of crop yields and some climatic variables for a period of 17 years (1990 - 2006) were used to...

Malaria and pneumonia occurrence in Lagos, Nigeria: Role of temperature and rainfall

The role of climatic parameters in the prevalence and severity of some common diseases is being speculated in the face of changing climate of the world. We investigate this supposition by expounding the relationship between malaria, pneumonia, rainfall and air temperature over Lagos, Nigeria. This study uses temperature and rainfall data of 60 years and 14 years record of reported cases of malaria and pneumonia...

Catch rate of juveniles Ethamatosa fimbriata, Sardinella maderensis, and Brachydeuterus auritus fishing in Freetown Peninsular

  We investigated the incidences of juvenile fishing according to fishing practices in Freetown peninsular. The industrial trawl fishing sector, despite its technology is not fully selective to avoid by-catch of juvenile fish, and artisanal fishing is so less for economic reasons. Ineffective enforcement of fishing regulations is a major cause to the catch of both targeted and non-targeted juvenile...

Multivariate statistical characterization of groundwater quality in Ain Azel plain, Algeria

Multivariate statistical techniques, cluster and principal component analysis were applied to the data on groundwater quality of Ain Azel plain (Algeria), to extract principal factors corresponding to the different sources of variation in the hydrochemistry, with the objective of defining the main controls on the hydrochemistry at the plain scale. Q-mode hierarchical cluster analysis grouped 54 groundwater samples into...

An evaluation of Iken fishing strategy in tropical Lekki lagoon, Nigeria

  This paper presents the results of the investigations of the fish aggregating device which served as fisheries enhancement techniques for the improvement of the productivity of the Lekki Lagoon between March 2006 and February 2008. The performance of the floating Island (Iken fishery) depends on the size and the thickness. Chrysichythys nigrodigitatus contributed 25.51, 23.42 and 25.19% of the total...

Determination of carnivores prey base by scat analysis in Samburu community group ranches in Kenya

  This study determined the prey base for four main carnivores found in Samburu community group ranches and grazing area, Lion (Panthera leo), Leopard (Panthera pardus), Wild dog (Lycaon pictus) and Hyaena (Crocuta crocuta, and Hyaena hyaena). A total of 96 scat samples including, 8 from Lion, 16 Leopards’, 2 Wild dogs’, and 70 Hyaenas’ were collected, identified and microscopically analyzed...
