Lichens as indicators of air pollution.
Field and laboratory studies have demonstrated that lichens are extremely sensitive to sulfur dioxide and that lichens are fairly sensitive to hydrogen fluoride and heavy metals. Further studies are necessary to assess lichens' relative sensitivity to oxidant air pollutants.
