Evaluation of polycyclic Aromatic Hydrocarbons and Selected Heavy Metals Levels in Water around Zaakpon, Rivers State

                      AbstractPolycyclic 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

Excess lifetime Cancer risk and Radiation Pollution hazard indices in rocks and soil of some selected mining sites in Nasarawa State, Nigeria

Radiation exposures from mining and mineral processing industries can lead to high incidence of disease conditions like nausea, lung cancer, sterility, fatigue, and diarrhoea among mineworkers. The concentration of primodial radionuclides (238U, 232Th and 40K) in some selected mining sites in Nasarawa State, Nigeria, was examined in this study. Soil and rock samples from eight different mining sites were collected and analyzed for radionuclides activity concentration by gamma ray spect...

LEACHATE COMPOSITION OF ISALE-IJAGBA AND OKE –DIYA DUMPSITES IN SAGAMU AND THE POSSIBLE ENVIRONMENTAL IMPACT ON SURFACE AND GROUNDWATER QUALITY.

ABSTRACTWhen solid waste is disposed of at landfills, it undergoes a combination of physical, chemical and microbial processes. These processes help to transform the waste into various water-soluble compounds termed (leachate) and transfer the pollutants from the refuse to the percolating water, leading to contamination of surrounding groundwater and surface water. Characterisations of the leachate originating from the Isale-Ijagba and Oke-Diya dumpsites (situated in Sagamu, Ogun State,...

Decolourization of Textile Dye Effluent by Resident Bacterial Species

Textile dye effluents are released into the environment without any pretreatment and pollute water, to prevent contamination of our valuable resources; removal of these pollutants is of great vitality. For this purpose, waste water samples were collected from dye contaminated sites of Kofar Mata dye pits based in Kano State. Certain parameters which include temperature and pH were determined in the Laboratory. The residual bacterial load was found to be in the range of 1.4 x106 - 4.0x106 cfu....

Offshore Oil and Gas Drilling waste: The Need for Pragmatic Change

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...

THE EFFECT OF ABATTOIR EFFLUENT ON PHYSICOCHEMISTRY AND BACTERIOLOGICAL ANALYSIS ON KARU RIVER, ABUJA (CASE STUDY: KARU ABATTOIR)

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

INDUSTRIAL GREYWATER RECYCLING AND REUSE: A SUSTAINABLE DEVELOPMENT FOR MILLIKEN & COMPANY, MIDDLETON

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...

SOLAR ENERGY: POTENTIAL FOR MITIGATING DEVASTATING EFFECTS OF CLIMATE CHANGE

ABSTRACTClimate change has been identified as one of the greatest challenge by all the nations, government, business and citizens of the globe. The threats of climate change on our green planet ‘Earth’ demands that renewable energy share in the total energy generation and consumption should be substantially increased as a matter of urgency. Nigeria’s energy development programme has been put under severe pressure with the ever-increasing demand supply gap. Due to predominance of fossil ...

SAVING THE DYING PLANET EARTH

Planet  earth  is  being  endangered  by anthropogenic  activities  ranging from industrial  activities  to  seemingly innocous activities  such  as  use  of  herbicides  on  farms.There  are possibilities  that the  resources  of the  earth  may  not be  sufficient   to  sustain the  needs   of  future  generations.There  are&nbs...
