Harnessing plants for pollution control: trends in phytoremediation research in Thailand

Abstract Phytoremediation is a nature-based solution that utilizes plants’ ability to reduce, remove, or detoxify environmental contaminants. This study performed a comprehensive bibliometric analysis using the Scopus database from 2005 to 2025 to evaluate the 20-yr research progress and development of phytoremediation technology in Thailand. The most influential authors, institutions, and research hotspots in this field were identified. Over time, the research focus has developed from plant-centric and single contaminant-based studies to more integrated phytoremediation technologies, such as amendment-assisted and microbial-assisted phytoremediation in co-contaminated environments. However, field-scale implementation remains constrained due to limited community engagement and systemic policy integration. To transition this technology from the lab to the field, future efforts must focus on fostering public engagement and designing evidence-based environmental policies.
