Phytoremediation, the practice of removing heavy metals from contaminated sites using plants, has emerged as a cost-effective, environmentally friendly green technology to restore damaged ecosystems. Mosses, in particular, demonstrate high phytoremediation potential due to their ability to accumulate heavy metals such as lead, zinc, copper, chromium, cadmium, and iron from contaminated soil and water. This review systematically examines 37 research articles published from 2000 to 2022, focusing on the on the use of mosses for phytoremediation. Moss species, such as Funaria hygrometrica Hedw, Scopelophila cataractae (Mitten) Brotherus, Dicranum scoparium Hedw, Dicranum polysetum Sw. ex anon, Hypnum cupressiforme Hedw, Physcomitrium cyathicarpum Mitt, Barbula constricta Mitt, and Leptodictyum riparium (Hedw.) Warnst. have been identified as ideal candidates for phytoremediation efforts. Specific species of mosses, such as Dicranum species, are noted for their excellent bioaccumulation capabilities of elements like vanadium, manganese, and rubidium, serving as indicators of air pollution. Additionally, Hypnum cupressiforme has proven to be a reliable indicator of sulfur dioxide in natural and anthropogenic sources. This comprehensive review highlights the significant phytoremediation potential of mosses, emphasizing their role as valuable bioaccumulators and indicators of heavy metals and pollutants. The findings highlight the necessity of further research to enhance the application of mosses in environmental management and remediation strategies, ultimately contributing to the development of sustainable and effective solutions for pollution control.
植物修复是指利用植物从受污染场地去除重金属的实践，它已成为一种经济高效、环境友好的绿色技术，用于恢复受损的生态系统。特别是苔藓，由于其能够从受污染的土壤和水中积累铅、锌、铜、铬、镉和铁等重金属，因而展现出很高的植物修复潜力。本综述系统地研究了2000年至2022年发表的37篇研究文章，重点关注苔藓在植物修复中的应用。已确定诸如大灰藓、瀑布藓、曲尾藓、多蒴曲尾藓、桧叶白发藓、圆蒴立碗藓、缩叶紫萼藓和湿原藓等苔藓物种是植物修复工作的理想候选者。特定的苔藓物种，如曲尾藓属物种，以其对钒、锰和铷等元素出色的生物累积能力而闻名，可作为空气污染的指示物。此外，桧叶白发藓已被证明是自然和人为来源中二氧化硫的可靠指示物。这篇全面的综述突出了苔藓巨大的植物修复潜力，强调了它们作为重金属和污染物的重要生物累积者及指示物的作用。研究结果凸显了进一步开展研究以加强苔藓在环境管理和修复策略中应用的必要性，最终为污染控制开发可持续且有效的解决方案做出贡献。
