Malaria is a global public health problem, caused by malaria parasites transmitted by the vector adult female Anopheles mosquitoes. The life cycle of Anopheles mosquito (Order: Diptera) has six stages egg, four larvae instars and pupa. The immature stages are aquatic and determine the abundance, distribution and fitness of the adult Anopheles mosquito. The physicochemical parameters (Conductivity, Salinity and Total Dissolved solids) of water affects survival and development of the larvae. Th...
This is a research work carried out on battery cage system of poultry management. It's all about how to minimize waste from poultry birds and also how to convey waste by employing the help of a belt conveyor
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...
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 the consu...
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...
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...
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....
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...
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...
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...
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...
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...
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 ...
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...
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...
