Lichens are advantage over vascular plants As a bioindicator of air pollution: because they have no wax & cuticle to protect cells (inner structure) Cortex: Fungal layer Algal layer Medulla 32. Fruticose : The most sensitive Lichens are differently sensitivity to air pollution Lichen as Bioindicator of Metal Pollution Pb, Ni, Cu, Cr, and Cd are some metals in cement dust, generated by cement industry (Alkhasman & Shawabkeh, 2006). The guidelines address the use of epiphytic lichens (bioaccumulation by native lichens and lichen transplants) to monitor spatial and temporal trends of element concentrations (macro-elements and trace elements) related to atmospheric pollutant depositions. Table 2 reports some bibliographical data on heavy metal bioaccumulation on lichens. Leafy lichens can survive a small amount of air pollution. They hypothesized that these algal-fungal complexes could possibly accumulate the different elements emitted from these geologic features. Abstract. Lichens PowerPoint PPT presentation .
