Evaluation of variation in the concentration of heavy metal provides vital information about the spatial behavior of the metals affecting the air quality. In the present study, lichen samples of the species Pyxine subcinerea Stirton were collected in the Rudraprayag valley to investigate the metal profile that bioaccumulated in lichens. Multivariate statistical analysis was carried out to elucidate possible contribution of various sources of pollution including anthropogenic sources on heavy metal profile of lichens. Cluster analysis successfully grouped geogenic and anthropogenic inputs represented by Al and Mn and Cu, Cd, Pb, and Zn, respectively. Principal component analysis also segregated sites based on the origin (major contributors).
