The role of mosses in 'clean and green' phytoremediation technology: a review paper.

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.
