The current study was designed for determination of copper and iron and some physicochemical properties of soils collected from two selected dumpsites (Saje and Sango) in Ogun State, Nigeria by digging two depths of about 125cm. Samples were taken at different depth intervals of 25cm (i.e 0-25, 25-50, 50-75, 75-100 and 100-125cm). The soil were analyzed for physicochemical parameters such as Organic carbon, Organic matter, Soil pH, Electrical conductivity, Particle size, Cation Exhangeable Ca...
Heavy metals have been a defining parameter concerning water quality. They have constituted a major degree in pollutants levels in the environment. The study was designed to investigate the comparative levels of heavy metals in colloidal and water samples in relation to the activities on the River Oyun and the activities around the sampling location. The samples were analyzed for six metals using Atomic Absorption Spectrophotometry. The results obtained showed that the concentrations of ...
ABSTRACT This research work is aimed at assessment of levels of heavy metals in soils and their environmental effects from three Mechanic Villages in Abuja namely; Apo, Kugbo and Zuba. To achieve the set target, soil samples were collected from five sampling points in each of the mechanic villages to a depth range of 0 - 15 cm with a stainless hand-dug auger. A control sample was also taken from a point of approximately 100 km where neither industrial nor commercial activities take place. Re...
Kajiado town, the County headquarters for Kajiado County which is classified as semi-arid area, lacks adequate water supply systems. The town had a projected population of 16,003 in 2013 (KNBS, 2010) but no functional municipal water supply system. There is no permanent river near the town and the town has a formation with poor aquifer such that even bore holes have low water yields. Water is sold at an exorbitant price given that a twenty (20) litre jerry can cost on average Kshs 10 whi...
ABSTRACT: The designed air driven engine is an economic friendly engine which operates with the aid of a compressed air. in principle, an air driven engine uses the expansion of compressed air to drive the pistons of an engine. an bio gas driven engine is a pneumatic actuator that creates useful work by expanding compressed gas. there is no mixing of fuel with gas as there is no combustion. An gas driven engine makes use of compressed gas technology for its operation the compressed air techn...
Abstract Polycyclic aromatic hydrocarbons, heavy metals and physiochemical parameters were measured in water samples from zaakpon community. The results shows that most of the parameters in water were within safe limits except turbidity, potassium and Phosphate while PAHs concentrations in water were below detection limit
ABSTRACT The gross alpha and beta radioactivity pollution of main water supplies in Dutsinma metropolis were measured using proportional gas counter. The results show that the gross alpha radioactivity in water samples is lower than the maximum contaminant level of 0.1Bq/L set by World Health Organization (WHO). The measured alpha activities have a minimum of 0.001±0.0.003 and the maximum of 0.146±0.034 Bq/L with mean of 0.029±0.002 Bq/L. The gross beta radioactivity in water samples is h...
Executive SummaryOffshore drilling for oil and natural gas have been ongoing since the 1800’s but little emphasis has been placed on the fate of drilling waste acquired during the drilling process. There are three main categories of waste that represent a potential concern based on current disposal practices. These waste categories are drilling fluids, drill cuttings and produced formation water (PFW). Existing and proposed policies related to the handling and disposal of these wastes wil...
The impact of Sewage and Abattoir effluent discharge into river resulted in water pollution there by reduces it quality.This study aimed at analysing the physicochemical and bacteriological parameters of Karu Abattoir effluent and Sewage discharge into Karu River in FCT ,Abuja, Nigeria in order to ascertain the quality and impact on Karu River. Four water samples along with one effluent ample were collected aseptically and subjected to standard microbiological and physicochemical analysis
This report is a product of an extensive research project seeking to recycle laundry wash water for Milliken Industrials Limited, Middleton, U.K. Data gathered from meter readings in Milliken Industrial Ltd, Middleton, has constantly indicated the laundry aspect of their manufacturing process as by far, the process that consumes the largest volume of water, thereby resulting in high water utility bills. This singular process contributes significantly to the company‘s operating cost, since a...
