Abstract

Surface water quality at Abuakwa South Municipal has received threats from surrounding mining communities, which are becoming a major concern to the public. As a result, this study aimed to assess water quality by examining the concentration of lead (Pb), cadmium (Cd), and zinc (Zn) pollution in surface water. Fifteen samples were obtained from surface water using a 1.5 L plastic bottle. The mean concentrations of Pb and Cd were above WHO guidelines of 0.01 and 0.003 mg/l, respectively, except for Zn which was below the stipulated limit of 3.0 mg/l. The geochemical process model shows that Cd, Pb, and Zn are adsorbing (released from the drainage to the surrounding environment) in sites 1 and 3 whereas Pb is desorbing (added to the drainage) in site 2. A hazard quotient greater than 1 was recorded for Cd in adults through the ingestion route of exposure at all the sites. Cancer risk also shows that the inhabitants are at risk through the ingestion route of exposure. The findings of this study suggest intake of water draining within the vicinity is unsafe and poses severe health risks.

加纳 Abuakwa 南市采矿点周围部分地表水中潜在有毒元素的水质分析和风险评估

Abuakwa South 市的地表水水质受到周边采矿社区的威胁，这已成为公众关注的焦点。因此，本研究旨在通过检测地表水中的铅（Pb）、镉（Cd）和锌（Zn）污染浓度来评估水质。使用 1.5 升塑料瓶从地表水中采集了 15 个样本。铅和镉的平均浓度分别高于世界卫生组织规定的 0.01 毫克/升和 0.003 毫克/升，但锌的平均浓度低于规定的 3.0 毫克/升。地球化学过程模型显示，镉、铅和锌在 1 号和 3 号地点被吸附（从排水系统中释放到周围环境中），而铅在 2 号地点被解吸（加入到排水系统中）。在所有地点，成人通过摄入途径接触镉的危险商数均大于 1。癌症风险也表明，居民通过摄入途径接触镉有风险。这项研究的结果表明，摄入附近的排水是不安全的，会对健康造成严重危害。
