Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous organic pollutants in urban environmentsincluding urban soils. Elevated concentrations of PAHs in urban soils are caused by incomplete combustion of petroleum and coal. This study assesses 16 individual PAH compounds in a total of 112 surficial soil samples. The objective was to assess and compare the levels of contamination as well as examine the main sources of PAHs in four urban agricultural soils using molecular ratios of some specifi...
The most relevant controls on groundwater quality within the Lower Pra Basin in Ghana were assessedusing Q-mode hierarchical cluster analysis (HCA). The objective was to determine the chemical characteristics of the various water groups and subgroups responsible for the groundwater evolution and identify the groundwater recharge and discharge zones within the basin. The Q-mode HCA have characterized hydrochemical data from a total of sixty-eight (68) boreholes and two (2) streams within the b...
Hydrochemical and stable isotopes (18O and 2H) analyses of groundwater samples were employed toestablish the origin of major dissolved ions in groundwater within the Lower Pra Basin. Results showed that, the major processes responsible for chemical evolution of groundwater include: silicate (SiO4)4- dissolutions, ion exchange reactions, sea aerosol spray and pyrite (FeS2) and arsenopyrite (FeAsS) oxidations. The groundwater is strongly acidic to neutral, with pH generally range from 3.5 to 7....
Calcite (CaCO3), dolomite [CaMg(CO3)2], silicatedissolution, ion-exchange and reverse ion-exchangereactions are the predominant processes influencinggroundwater quality in the Savelugu–Nanton District. Themain objective of this study is to characterize groundwaterand delineate water–rock interactions responsible for thechemical evolution of groundwater in the District. Eighty-one (81) boreholes were sampled for quality assessment.Results showed that, the pH of the boreholes are slightly a...
ABSTRACT Plastics are important for man use. It cannot be eradicated nor forbidden. Then how should we go about the debris/waste of plastics? How can we stop the single-use method of plastic? Should we ignore and look for another alternative? These above are some of the questions we ask ourselves on daily basis TABLE OF CONTENTS Title page Acknowledgments Abstracts Literature review Results Recommendations References
Abstract Several researches have shown that the accumulation of heavy metals in green-leafy vegetables is of increasing concern due to food safety threat and potential health risks. Therefore, the aim of this research was to analyze the amount of heavy metals accumulated in three green-leafy vegetables consumed in Dutse metropolis, Jigawa state, Nigeria. Three (3) samples of each of the vegetables were collected randomly from two (2) different markets in Dutse Metropolis. The sample coll...
This paper demonstrates that interdisciplinary alliances on environmental education projects can effectively address the gap between complex environmental problems in the real world and disciplinary curricula in a university. We describe an alliance between an advanced communication course and a general science course wherein we addressed interconnections of energy efficiency, economics, and global climate change with respect to their impact on individuals, local businesses, and society. This...
This paper explores an application of Catholic theology to mitigate the current destruction of God's creation underway due to global climate destabilization. Specifically it describes the possibility of the U.S. Catholic Church adopting a systematic plan to catalyze the world energy market to shift to solar photovoltaic energy, a non-polluting renewable energy source. The science behind the ecological crisis and climate change in the context of the Catholic basis for environmental stewardship...
As the economic costs of energy and the negative externalities associated with the combustion of fossil fuels threaten the economic viability of greenhouses in northern climates there is a renewed interest in the use of waste heat. This paper presents a technical and economic methodology to determine the viability of establishing waste heat greenhouses using the waste heat from industrial processes in northern climates. A case study is presented of an exchange between a tomato greenhouse and ...
Solar photovoltaic (PV) technology represents a promising method to prevent dangerous global climate change, however full solar penetration demands substantial surface areas, possibly encroaching on arable land. To avoid repeating the mistakes of previous attempts to convert agricultural land to energy, arable land currently used for crops with known health hazards can be considered for conversion. Tobacco is the leading cause of avoidable death globally, and despite increasingly stringent co...

Key words: Environmental Impact Assessment (EAI,Sustainable Development: Development, Regulation,Global Warning, Ecosystem, Green house Gas (GHG) ABSTRACT This study investigated the environmental impacts of build...
The environment of man plays a significant role in the development of man and in determining his health status, no animal or plant has changed the environment as much as man (Mohtadi, 2015). The earth, air, land and water have witnessed man’s devastating activities (Martonas, 2017). In some instances the environment has been altered in a manner that its originality cannot be regained. Today the threat of oil spillage, air pollution, global warming, earthquake, landslides and other natur...

ABSTRACT The analysis of the problem of solid waste management associated with Port Harcourt Metropolis in developing countries, like Nigeria, have become pronounced in recent years as a result of urbanization and inadequate disposal of waste. This paper examines the current method of waste disposal in Port Harcourt city area of River State,...
This project work capture the causes and effects of flooding in different parts of the nation. 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 ...
