POLLUTANTS IN BELO JARDIM (PE) USING Cladonia verticillaris (LICHEN) AS BIOMONITOR.Cladonia verticillaris used in this study was collected in the cerrado vegetation of Saloá (PE, Brazil) and transplanted in plastic containers on soil from the collection place to Belo Jardim (PE) that possesses lead smelters and battery industries.The experiments were disposed at eleven different places for evaluating the dispersion of pollutants and their effects on the biomonitor.The exposed lichens were collected over eight months and submitted to thin layer and high performance liquid chromatographies, and scanning electron microscopy.C. verticillaris placed in the vicinity of the emission sources demonstrated alteration in its metabolism, decreasing the production of its major compound, fumarprotocetraric acid, and deterioration of its external and internal surfaces.
