Abstrakt: This article explores the use of lichens in biomonitoring to assess heavy metal concentrations, environmental factors, and lichen diversity in Bengaluru, Karnataka, India. Lichens are cost-effective options for biomonitoring due to their unique characteristics. The study examined heavy metal concentrations, acidity, and electrical conductance in different tree species across six locations. The findings revealed a correlation between acidity levels and lichen species in all tree species studied. Lichen diversity was lower in areas with heavy traffic and industrial activity. The article emphasizes the importance of considering abiotic factors and conducting chemical analysis in environmental pollution studies. The analysis of tree bark acidity, conductivity, and buffering capacity in different locations revealed significant variations. Bark pH values were lower in polluted areas with heavy traffic and higher air pollution levels. Pollution can impact the conductivity and buffering capacity of tree bark through the deposition of contaminants and chemical reactions. Furthermore, the concentration of heavy metals in lichens can indicate pollution levels in the environment, with areas near industrial and heavily trafficked areas showing higher levels. The study concludes that Station 2 and Station 4 are the most polluted locations, while Station 3 and Station 6 have lower pollution levels due to favorable conditions and green spaces.
