Abstract
Phaeophyscia
hispidula (Ach.) Moberg, foliose lichen is widespread in Garhwal
Himalayas and grows luxuriantly on different substratum in polluted as well
as non polluted sites, where no other macrolichens are able to colonize. The
elemental concentration and biochemical parameters in P. hispidula
collected from Dehra Dun city were analyzed to assess its tolerance to heavy
metals. The major source of pollution in the city is automobiles. Among the
biochemical parameters protein was significantly and negatively correlated
with pigment concentrations (r= -0.3838 (Chl.b); -0.5809 (Carotenoid);
-0.5034 (OD)) however it is significantly positively correlated with Cd (r =
0.6822: P<0.01). Among heavy metals, Cd was negatively correlated with Cu
(r = -0.4639), Fe (r = -0.2676), and Zn (r = -0.0549). It was observed that
the chlorophyll and protein content increased parallel to the level of
metallic pollutants indicating the mechanism of stress tolerance in P.
hispidula. The study shows that P. hispidula is tolerant to
inorganic pollution and a useful tool for biomonitoring of air quality in the
Himalayan region.
