The aim of this work was to find out the impact of pollutants emitted from brick kiln and vehicles, on lichen density and diversity, as such the site was chosen accordingly in the vicinity of highway where the impact of both was clearly visible. Only three (3) species of lichens of foliose growth form were recorded. The analysis of air quality in the Khanabal area which was based on determining fraction of RSPM, NRSPM, SPM, SO and NO revealed that all these parameters showed values higher than the prescribed norms.Potential sources of pollutants were evaluated ; the Brick kiln ,its fuelling material ,the huge brunt from exhaust pipes of vehicles ,use of adulterated fuel, unpaved road used for loading and unloading of materials, soil extraction process all these added pressure to local environment which reflected on lichens in area causing grave and irreparable damage to them. The data on frequency, density and abundance of different lichen species was also recorded and correlated with the qualitative and quantitative aspect of lichens. The tree species showed variation in bark chemistry (pH, water holding capacity) along the pollution gradient. The study thus allowed us to monitor the extent of pollution and determine its quantity through lichen species in the area
