摘要：Lichens are useful biological indicators of environmental contamination for a variety of metals and radionuclide of both natural and artificial origin. In present study, an active biomonitoring study was carried out with a commonly growing foliose species of Dirinaria applanata (Fée) D.D. Awasthi, collected from Pichavaram mangroves of Tamil Nadu. A total of twelve metal (Al, Cd, Cr, Co, Cu, Fe, Hg, Mg, Mn, Ni, Pb and Zn) accumulated in the transplanted lichen thalli of Dirinaria applanata at four sites (Parangipettai, SIPCOT, Cuddalore OT and NT) were targeted. The transplantation site near SIPCOT, being an industrial area exhibited highest concentration of Al, Cd, Co, Cu, Fe, Hg, Mg and Mn than the other sites. Cr (1009.98±µg/g dw) and Ni (7.35± µg/g dw) were found to be more at Cuddalore OT having higher anthropogenic activities while Pb and Zn were recorded maximum at Cuddalore NT with more vehicular activity. The level of most of the metals reached above the EPA standard. The accumulation of metals in different transplanted sites clearly indicates a particular type of metal accumulation with an anthropogenic activity in that area
