Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This research aims to investigate the distribution of trace elements in surface and groundwater of the Biu Volcanic Province in Northeastern Nigeria. The study focuses on the potential health impact of these elements on the local population, particularly regarding their toxicity and deficiency. Here are the key themes addressed in the study:

• Trace element distribution in soil, surface water, and groundwater in the Biu Volcanic Province.
• The influence of soil composition on the chemistry of water sources in the area.
• Comparison of trace element levels to WHO admissible standards to assess potential health risks.
• The relationship between trace element exposure and human health, particularly the occurrence of nail deformities, skin problems, and other health issues.
• Recommendations for further research and the development of strategies to mitigate the potential health hazards posed by trace element contamination.

Zusammenfassung der Kapitel (Chapter Summaries)

• Chapter One: General Introduction: This chapter provides a comprehensive overview of the study area, its location, accessibility, relief, drainage, climate, vegetation, land use, and the aims and objectives of the research. It discusses the importance of trace elements in the environment, their impact on human health, and the need to study their concentration in the Biu Volcanic Province.
• Chapter Two: Literature review: This chapter reviews existing literature on the effects of trace elements in volcanic areas, particularly focusing on the health implications of arsenic, fluorine, and selenium. It presents examples of studies conducted in different parts of the world that highlight the potential health hazards associated with these elements in volcanic environments.
• Chapter Three: Detailed Geology and Hydrogeology of the study area: This chapter details the geological and hydrogeological characteristics of the Biu Plateau, including the different rock types present, the structure of the rocks, and the distribution of surface and groundwater resources. It describes the main aquifer systems, their recharge mechanisms, and the general direction of groundwater flow.
• Chapter Four: Hydrogeochemistry: This chapter outlines the methodologies used in the study, including sample collection procedures, water sample preparation, soil sample preparation, and the analytical technique employed (Inductively Coupled Plasma Optical Emission Spectrometry - ICP-OES).
• Chapter Five: Presentation of Results/Discussions: This chapter presents the results of the geochemical analyses of soil and water samples collected in the study area. It includes detailed discussions on the concentrations of major and trace elements in both soil and water, comparing these levels to the WHO admissible standards for drinking water. It also analyzes the potential health implications of the observed trace element levels and examines the evidence of health problems among the local population.
