EFFECTS OF LIQUID WASTES FROM AUTOMOBILE WORKSHOPS ON PROPERTIES OF SOILS IN ENUGU STATE, NIGERIA
ABSTRACT: This study was carried out in Udi, Udenu and Nsukka Local Government Areas, in Enugu state. The effects of liquid wastes from automobile workshops on some selected soil properties of the study area were investigated. Auger samples were collected at two depths, (surface, 0- 20cm) and (subsurface, 20- 40cm) of automobile wastes contaminated sites and 100m away for uncontaminated sites. Core samples were collected from both soils and surface samples were again collected for planting m...
Review on Some Plants as Bio-pesticides
Abstract: The study used Onion (Allium Cepa), Garlic (Allium Sativum L.) and Sour Orange (Citrus Aurantium) to assess their effectiveness as bio- pesticides. The study also revealed that plants play vital roles towards the storage of many food stuffs. The consideration for the used extracts of plants origin is that they were easily biodegradable, effective on some pests and considered safer in pest control operations as they minimized pesticide residues and also ensured safety of th...
A comparative study of noise pollution levels in Ilorin metropolis
The noise pollution is a major problem for the quality of life in urban areas. This study was conducted to compare the noise pollution levels at busy roads/road junctions, passengers loading parks, commercial, industrial and residential areas in Ilorin metropolis. A total number of 47-locations were selected within the metropolis. Statistical analysis shows significant difference (P < 0.05) in noise pollution levels between industrial areas and low...
Isolation and characterization of PGPR from the rhizopheres of selected vegetables in Ogun state
ABSTRACT Beneficial bacteria that colonize the root of plants and are capable of stimulating the growth of plants directly or indirectly are called plant-growth promoting rhizobacteria. The objective of this study was to isolate and characterize plant-growth promoting rhizobacteria from the rhizosphere of some selected vegetables collected at different locations in Ago-iwoye, Oru and Ijebu-Igbo in Ijebu-North local Government Area of Ogun state, using general microbiological and biochemical t...
Thermodynamic limitations to nuclear energy deployment as a greenhouse gas mitigation technology
To both replace fossil-fuel-energy use and meet the future energy demands, nuclear energy production would have to increase by 10.5% per year from 2010 to 2050. This large growth rate creates a cannibalistic effect, where nuclear energy must be used to supply the energy for future nuclear power plants. This study showed that the limit of ore grade to offset greenhouse gas emissions is significantly higher than the purely thermodynamic limit set by energy payback times found in the literature....
An Assessment of Krokodilrivier Water Quality in Mpumalanga Province, South Africa.
According to the Sustainable Development Goals (SDG) ‘s indicator baseline 2017 report of South Africa, the percentage of the population using safely managed drinking water services has remained more or less constant around 91% between 2014 and 2016. The observation of the same variable from 1996 to 2011, shows a significant increase from 76.6% to 89.4%. This therefore means between 2011 and 2016, the change has been insignificant. To have a sample analysis in this regard, on the ...

Some Ecological Disasters And How They Affect The Human Environment In Nigeria
Ecological DisastersA “disaster” can be defined as ‘a calamitous event, especially one occurring suddenly and causing great loss of life, damage or hardship, caused by negligence, bad judgment, or the like, or by natural forces, as a hurricane or flood….the emphasis is on grief or sorrow caused…or the destruction or irreparable loss. they often come with such inexplicable emotional force that triggers in man that innate human desperation or determination for survival against a...
Isolation of oil degradation bacteria
Petroleum-based products are the major source of energy for industry anddaily life. The technology commonly used for the soil remediation includesmechanical, burying, evaporation, dispersion, and washing. However, theseTechnologies are expensive and can lead to incomplete decomposition ofcontaminants (Zaid A. Pirzada.2015) The Bioremediation techn...
SUSTAINABLE ECOSOPHY FOR AFRICA: AN ETHICAL EVALUATION OF THE AFRICAN ENVIRONMENT
Ecosophy is an Ecological Philosophy aimed at a Philosophical study of the Ecological knowledge. This book is particularly an ethical assessment of the African environment as its setting is basically on the African environment.
PRODUCTION OF BIOGAS USING COW DUND, GRASS CUTTINGS, PIG WASTE
ABSTRACTThis study comparatively analysed biogas production from three waste materials: Grass - Axonopus compressus, cow dung and pig waste slurry, with respect to the effects of carbon/nitrogen (C:N) ratio on biogas yield. A mixing ratio of 1:10 (one (1) part of substrate to ten (10) parts of water) was used. Nine 2L plastic digesters, were used for the study. Digestion was carried out in triplicates, 3 digesters for each substrate. The C:N ratios of the substrates were as follows: Axonopu...
PHYSICOCHEMICAL PARAMETERS & LEVEL OF SOME TOXIC METALS IN STREET DUST
ABSTRACT This research study the concentration of certain toxic metals in street dust along road construction site and relate the finding to the standard control measure to determine the extent to which environmental uncontrolled process can pollute the environment. This study therefore investigate the Physicochemical parameters of street dust and concentration of three toxic metals; Nickel (Ni), Copper (Cu) and Cadmium (Cd) in Arakale – NEPA Road in Akure City of Ondo State. ...
SUSTAINABLE WASTE TO WEALTH SCHEME FOR THE UNIVERSITY OF LAGOSA CASE FOR PET BOTTLES
ABSTRACT Polyethylene terephthalate (PET) bottles are plastic bottles derived from the raw material known as polyethylene terephthalate). The PET bottles are widely used for packaging carbonated drinks, beverages, food items, mineral water. Due to high consumption of PET bottles, trillions of PET bottles are disposed every year through, land filling, incineration, and ocean dumping; thus, creating nuisance and causing problem to the environment. This work aims to find an environmentally fr...
AIR POLLUTION TOLERANCE INDEX OF SOME TREE SPECIES AROUND ELECTRICITY GENERATING HOUSES IN AHMADU BELLO UNIVERSITY MAIN CAMPUS, ZARIA, NIGERIA
The study examined the Air Pollution Tolerance Index (APTI) of seven different tree species growing around electricity generating houses within the Ahmadu Bello University (ABU) Main campus, Samaru. Four parameters, leaf relative water content (RWC), ascorbic acid content (AA), total chlorophyll (TCH) and pH of leaf extract were used to compute the APTI of the tree species. Results indi...
ASSESSING HEAVY METAL CONCENTRATION IN SOIL OF FABRIC PRODUCTION VICINITY
ABSTRACT The study of heavy metal deposition and accumulation in fabric production vicinity is of increasing interest because of the awareness that heavy metals present in soils may have negative consequences on human health and the environment. This study describes the assessment of heavy metal concentration in soils of fabric production vicinity a case study of Itoku Adire Kampala market, Abeokuta, Ogun State, Nigeria. Five (5) top soil samples and 5 sub soil samples were colle...
