The study investigates air quality and the distribution of trace elements in urban areas of Tehran using the epiphytic lichen Ramalina sinensis as a bioindicator. Lichen thalli were collected from unpolluted areas and transplanted to six urban sites for six months. Post-exposure, the concentration of 12 elements was analyzed using ICP-MS, and the data were evaluated using various statistical and environmental pollution indices. Results showed a significant bioaccumulation of essential elements, with notable site-specific variations. The contamination sources were mainly attributed to vehicular emissions, as revealed by PCA and enrichment factor analysis. This study highlights the utility of R. sinensis in air quality biomonitoring, offering a cost-effective and reliable alternative to conventional monitoring systems.
