Datasets on Arsenic and Cadmium Contamination in Nigerian Domestic Water

This dataset is a compilation of information on the presence of arsenic and cadmium in Nigerian drinking water sources. Arsenic and cadmium are classified as group 1 carcinogens, which pose serious health risks to the public. The data presented were compiled from the review of research articles published between 2010 and 2023 on Nigerian domestic water sources such as groundwater (hand-dug wells, machine wells, and boreholes) and surface water (rivers, streams, and lakes). The sources of the heavy metals were traced to anthropogenic activities and geogenic sources. The anthropogenic activities that give rise to arsenic and cadmium in drinking water sources include industrial waste discharge into the environment, fertilizer applications, and mining. The geogenic causes of arsenic and cadmium in domestic water sources refer to the natural deposits in soils and stream sediments. The study showed that anthropogenic activities accounted for 61% and 68% of arsenic and cadmium pollution in drinking water, respectively, while the remaining cases were attributed to geogenic causes. Some of the studies linked arsenic and cadmium contamination to chronic illnesses such as kidney failures, liver sclerosis, and central nervous problems in Nigeria. This data is important for understanding arsenic and cadmium's pathways, transport processes, and fate. The data can be used by researchers to understand patterns and trends in water contamination. It can also be used by policymakers and health professionals to plan the necessary interventions to remediate the problem. Furthermore, this data can guide the much-needed epidemiological studies to determine the areas where the problem is prevalent and to link the reports of ailments in the affected areas to water contamination by arsenic and cadmium.

本数据集汇聚了尼日利亚饮用水源中砷和镉存在的相关信息。砷和镉被归类为一类致癌物，对公众健康构成严重威胁。所提供的数据系通过对2010年至2023年间发表的关于尼日利亚家庭水源（如地下水[手挖井、机械井和钻井]和地表水[河流、溪流和湖泊]）的研究论文进行综述而汇编而成。重金属的来源被追溯至人为活动及地质成因。引起饮用水源中砷和镉的人为活动包括工业废水排放至环境中、肥料的应用以及采矿活动。家庭水源中砷和镉的地质成因指的是土壤和溪流沉积物中的自然沉积。研究表明，人为活动分别占饮用水中砷和镉污染的61%和68%，其余案例则归因于地质成因。部分研究将砷和镉污染与尼日利亚的慢性疾病，如肾功能衰竭、肝硬化和中枢神经系统问题联系起来。这些数据对于理解砷和镉的迁移路径、传输过程及归宿至关重要。研究人员可以利用这些数据来了解水污染的规律和趋势。此外，政策制定者和卫生专业人员亦可利用这些数据来规划必要的干预措施，以解决这一问题。更进一步，这些数据可为亟需的流行病学研究提供指导，以确定问题高发区域，并将受影响地区的疾病报告与砷和镉污染联系起来。
