Periodic Report on the Vea Dam’s Water Quality for Artisanal Fishery, Irrigation Agriculture and Domestic Purposes in Bongo District of Upper East Region in Ghana

The physico-chemical quality of 180 water samples from the Vea Dam in Bongo District of the Upper East Region were analyzed using standard field and laboratory techniques at the Water Research Institute, Tamale in Northern Region of Ghana. The mean ranges of the respective parameters were much closer within the same rows. Its maximum values were : total dissolved solids (85.23 ± 13.162mg/l), conductivity (141.667 ±...

Seasonal Variation of Heavy Metal Speciation in soil and stream sediments from hospital waste dumpsite in Ilesa, Southwestern Nigeria

A speciation study of some heavy metals in soil and stream sediments around a hospital waste dumpsite was investigated. Selective sequential extraction procedure was used to fractionate the metals into 4 operationally defined groups: Exchangeable and metal bound to carbonate, oxyhydroxide of Fe and Mn, organic matter and the residual fraction. The result of speciation analysis of Fe, Mn, Zn, Cu, Cd and Pb in the soil...

PERCEPTION AND MITIGATION PREFERENCES ON CLIMATE CHANGE AMONG RESIDENTS OF NAIROBI CITY COUNTY

As result of compounding factors related to environmental, social, economic and political pressures, it is feared that the impacts of climate change and variability may overwhelm resilience of urban systems in developing countries if adaptation and mitigation strategies are not strengthened. Understanding how the urban residents perceive and respond to climate change is necessary for the purpose of formulating informed...

Assessment of trace metal distribution and contamination in poultry farm surface soil of Osun State, Southwestern Nigeria

In this study, the seasonal variations in concentration levels of selected heavy metals (As, Cd, Cu, Fe, Pb and Zn) in soils within the vicinity of the three major poultry farms in Osun State, South-Western Nigeria were investigated during two major seasons of Nigeria to ascertain the possible environmental impact of these agricultural farmland. Results of the atomic absorption spectrophotometric (AAS) analysis of samples...

EVALUATION OF DISPERSED WATER FROM NIGERIA’S CRUDE OIL BLEND AND ITS EFFECTS ON CRUDE OIL PROPERTIES AND PRODUCTION EQUIPMENT

Dispersed water from crude oil obtained from ten different producing wells in the Niger Delta area of Nigeria were analyzed based on American Standard for Testing and Materials to determine the effects of the physicochemical properties on crude characteristics and the production equipment. Results shows: pH (7.51-8.60), salinity (11174.00 - 21469.00 mg/l), conductivity (12698.00 - 24396.00 µS/cm), sulphate (3.00 - 23.00...
