Determination of heavy metal contamination of well water in abakpa area of enugu metropolis. health and kinetics

Project Abstract

The contamination of well water by heavy metals is a significant concern in many urban areas, including the Abakpa area of Enugu metropolis. This study aimed to determine the levels of heavy metal contamination in well water in Abakpa and assess the potential health risks associated with this contamination. The heavy metals analyzed in this study included lead, cadmium, arsenic, and chromium, which are known to have adverse health effects on humans. Water samples were collected from wells in different locations within the study area and analyzed using atomic absorption spectrophotometry. The results revealed varying levels of heavy metal contamination in the well water, with lead being the most prevalent contaminant. The concentrations of heavy metals exceeded the World Health Organization (WHO) and Nigerian Standard for Drinking Water Quality (NSDWQ) guidelines in some samples, indicating a potential health risk to the residents relying on this water source. Health risk assessment was conducted using the hazard index (HI) and carcinogenic risk (CR) methods. The results showed that chronic exposure to the contaminated well water could pose health risks to the residents, especially children and the elderly, who are more vulnerable to the adverse effects of heavy metals. The HI values exceeded the safe limit of 1 in some cases, indicating a potential health hazard. Furthermore, the study investigated the kinetics of heavy metal adsorption onto soil particles in the study area. Batch experiments were conducted to study the adsorption behavior of heavy metals onto soil samples collected from the wells. The results showed that the adsorption of heavy metals onto the soil followed pseudo-second-order kinetics, indicating a strong affinity of the soil for these contaminants. Overall, the findings of this study highlight the urgent need for remediation measures to reduce heavy metal contamination in well water in the Abakpa area. Public health interventions, such as providing alternative safe water sources and raising awareness about the risks of heavy metal exposure, are essential to protect the residents from the adverse health effects associated with contaminated well water. Further research is needed to explore sustainable solutions to mitigate heavy metal contamination and ensure access to safe drinking water in urban areas.

Project Overview

<p> </p><div><p><strong>1.1 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; BACKGROUND INEORMATION</strong></p><p>This study is on the determination of heavy metal contamination of well water in Abakpa, Enugu metropolis. Water to a chemist is a chemical compound with two atoms of hydrogen and one atom of oxygen in each of its molecules. It has multi – uses and indispensable for continuous existence of plants and animals. One of its artificial sources is well water from well if impure or contaminated is not safe for its beneficiaries whether used directly or indirectly.</p><p>Heavy metal is one of its pollutants. They cannot be detected by sight, taste or smell but by chemical analysis using suitable analytical techniques. When water is not safe to its beneficiaries it means there are adverse effects due to the presence of contaminants. Through the determination of the contaminants the problem haly sowed. Determination in this context means finding out or calculating the heavy metal contaminants (qualitatively and quantitatively). Preventive measures can be taken and the pharmacists and doctors can offer lasting solution after knowing the source of the problem.</p><p>1.2 &nbsp; &nbsp; <strong>STATEMENT OF THE PROBLEM &nbsp; &nbsp; &nbsp; &nbsp; </strong></p><p>Heavy metal contamination in very harmful. There are adverse effect associated with it. There effects may be health environmental or irrigational depending on the use of contaminated water. In consequence of the above fact, the following are subject of concern; how can heavy metal contaminant of well water be determined? What are the health effects of heavy metal contaminated of well water in Abakpa area of Enugu Metropolis?</p><p>The aims of this study are to determine possible heavy metal contaminants of well water in Abakpa, Enugu metropolis and tp inform the community and other of their health effects.</p><p>A &nbsp; &nbsp; &nbsp; Is well water Abakpa (Enugu) contaminated with heavy metal?</p><p>B &nbsp; &nbsp; &nbsp; what are heavy metal contaminates and when they aid to be harmful?</p><p>C &nbsp; &nbsp; &nbsp; how can heavy metal contamination in water be determined?</p><ul><li><strong>SIGNIFICANCE OF THE STUDY</strong></li></ul><p>This study in a timely and interesting one in this era; when there are poliferation of pure water firm and source of water to meet the demand of the people. Some of the pure water factorice do not have laboratory or scientific to check for safety of water for man use. Through this study the right source to meet in made known.</p><p>In addition , the appearance that will call for examining (well) water for heavy metal contaminants are itemized. The simplest and less expensive method that will give a specific and accurate result in determining heavy metal contaminant is made know to a chemist. Specification from authorized health organization are made available. Their health effects are not left out. The degree of their effects on man and other materials show the need for control land prevention. Prevention some people say is better than cure. The case where drug (s) in needed the right person to meet is made known. No doubt the study would be of colossal benefit it to the people of Abakpa Enugu metropolis and other people.</p><p><strong>1.6 &nbsp; &nbsp; LIMITATION OF THE STUDY</strong></p><p>The study was limited by the following factor;</p><p>A &nbsp; &nbsp; &nbsp; Money – this is very essential for any study to be a success. Due to insufficient money and the cost of the reagent, this study was limited.</p><p>B &nbsp; &nbsp; &nbsp; Faulty and unavailable analytical instrument- done analytical instruments were not available they were faulty.</p><p>C &nbsp; &nbsp; &nbsp; Time- due to shortness of time the most important information was considered.</p><p>D &nbsp; &nbsp; &nbsp; reagents and apparatus- some of the needed reagents and apparatus were not available.</p><p></p></div><h3></h3><br> <br><p></p>
