Plant material from Ramalina celastri (Spreng.) Krog & Swinsc., Tillandsia capillaris Ruiz & Pav. f. capillaris and Tillandsia tricholepis Baker were transplanted to eleven monitoring sites, categorized as urban, farming and farming/cattle-raising. The concentrations of pigments, hydroperoxy conjugated dienes, malondialdehyde and sulfur were determined. Chlorophyll b/ chlorophyll a, phaeophytin a/ chlorophyll a ratios were also calculated, and a Pollution Index (PI) and a Foliar Damage Index (FDI) were calculated from some physiological parameters. R. celastri showed higher levels of sulfur in urban sites whereas Phaeophytin a/Chlorophyll a was higher in farming and cattle-raising sites. T capilllaris showed higher sulfur contents in urban sites whereas malondialdehyde concentration and foliar damage values were higher in urban and cattle-raising sites. Finally, T. tricholepis showed higher values of malondialdehyde and foliar damage in samples transplanted to urban and cattle-raising sites.
