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 density residential areas, industr...

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 dynamics...

Some Ecological Disasters And How They Affect The Human Environment In Nigeria

A “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 all adversities, n...

Isolation of oil degradation bacteria

Petroleum-based products are the major source of  energy for industry and daily life. The technology commonly used for the soil remediation includes mechanical, burying, evaporation, dispersion,  and washing. However, these Technologies are expensive and can lead to incomplete decomposition of contaminants (Zaid A. Pirzada.2015) The Bioremediation technique is a pollution treatment technology that uses biological systems to catalyse the destruction or transformation...

PRODUCTION OF BIOGAS USING COW DUND, GRASS CUTTINGS, PIG WASTE

ABSTRACT This 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:  Axonop...

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. A total numbe...

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 ...

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 collected rando...

STUDIES ON THE HAEMATOLOGICAL CHARACTERISTICS OF CLARIAS GARIEPINUS FROM GUBI DAM, BAUCHI STATE, NIGERIA

ABSTRACTStudies were carried out to determine the haematological characteristics of Clarias gariepinus healthy specimens were obtained from Gubi dam. Blood sample ranging between 1.0-1.5ml were taken with the aid of sterilized syringe (21G) inserted by caudal vein puncture. The haematological parameters for each blood specimen were measured using automated haematological analyzer (sysmex  Kx 21N; 000758 model). Blood biochemical analysis to determine plasma albumin, glucose, protein, sodi...

FLOODING IN NIGERIAN CITIES: PROBLEMS AND PROSPECT. (A CASE STUDY OF BENIN CITY, EDO STATE)

ABSTRACT Nigeria is the most populous Black race country in Africa and in the world with a total land area of 983,213 km2 occupied by over 160 Million people: The interaction of these millions of people with their environment has left indelible mark on the landscape. Urbanization, deforestation, flooding, desertification, over population and all kinds of pollution are some of the resultant effects of man’s interaction with his environment. These changes result from the populace attempt to ...
