A scientometric analysis of biomonitoring with plants

Abstract

This work is focused on the biomonitoring of trace element atmospheric pollutants using Tillandsias, mosses, and lichens. A scientometric analysis was conducted by using two databases: Scopus and Web of Science, resulting in the selection of 249 records. Passive biomonitoring was dominant (~52%), while active monitoring represented ~36%. A comparison of the usage of moss, Tillandsia, and lichen was performed, showing successful cases. Main characterization techniques included ICP-MS/OES, INAA, and AAS. Urban (35%) and industrial (38.4%) environments were the most studied. Despite some limitations, biomonitoring is a powerful, low-cost tool and a Nature-based Solution, especially suitable for low-income regions. Russia and Romania stand out in adoption in the period of this research (2020 – 2025), but the Americas and Africa show a lack of incentives, highlighting the need for greater global support.
