砷污染及其对健康的相关影响已被广泛报道，并在过去几十年中引起了全球的关注。尽管砷的自然分布有限，但人类活动增加了砷向远方的流动性，从而增加了受砷污染影响的人数。砷具有复杂的生物地球化学循环，在污染中具有重要作用。因此，本文对砷的生物地球化学循环进行了全面分析，砷的生物地球化学循环决定了砷污染的发生。考虑到砷的毒性和性质，本工作还分析了世界各地砷污染的现状。值得注意的是，亚洲南部、非洲中西部、欧洲西部和拉丁美洲是砷污染的主要热点地区。利用scopus数据库进行文献计量分析，具体搜索砷污染、健康危害等关键词，获取相关数据。检索了2003年至2023年20年间的Scopus数据库，最终筛选出1839篇文章，使用VOS查看器进行进一步分析。对砷污染及其健康危害的文献计量分析表明，砷污染主要是人为源造成的，砷暴露的主要来源是饮用水、海产品和农产品。人们发现砷污染与严重的健康危害有关，例如癌症和其他健康问题。因此，考虑到问题的严重性，很少有人提出用于治理砷污染的可持续修复技术，例如微生物吸附、生物废料、纳米材料、人工湿地、植物修复和微生物生物修复。这些方法对环境友好且高度可持续，因此适合当前的环境危机。

Arsenic pollution cycle, toxicity and sustainable remediation technologies: A comprehensive review and bibliometric analysis

Arsenic pollution and its allied impacts on health are widely reported and have gained global attention in the last few decades. Although the natural distribution of arsenic is limited, anthropogenic activities have increased its mobility to distant locations, thereby increasing the number of people affected by arsenic pollution. Arsenic has a complex biogeochemical cycle which has a significant role in pollution. Therefore, this review paper has comprehensively analysed the biogeochemical cycle of arsenic which can dictate the occurrence of arsenic pollution. Considering the toxicity and nature of arsenic, the present work has also analysed the current status of arsenic pollution around the world. It is noted that the south of Asia, West-central Africa, west of Europe and Latin America are major hot spots of arsenic pollution. Bibliometric analysis was performed by using scopus database with specific search for keywords such as arsenic pollution, health hazards to obtain the relevant data. Scopus database was searched for the period of 20 years from year 2003–2023 and total of 1839 articles were finally selected for further analysis using VOS viewer. Bibliometric analysis of arsenic pollution and its health hazards has revealed that arsenic pollution is primarily caused by anthropogenic sources and the key sources of arsenic exposure are drinking water, sea food and agricultural produces. Arsenic pollution was found to be associated with severe health hazards such as cancer and other health issues. Thus considering the severity of the issue, few sustainable remediation technologies such as adsorption using microbes, biological waste material, nanomaterial, constructed wetland, phytoremediation and microorganism bioremediation are proposed for treating arsenic pollution. These approaches are environmentally friendly and highly sustainable, thus making them suitable for the current scenario of environmental crisis.
