Potential of epiphytic lichen Pyxine cocoes, as an indicator of air pollution in Kolkata, India,
Proceedings of the National Academy of Sciences, India, Sect. B Biological Sciences,
93(1): 165–180
The accumulation of trace elements in the thalli
of epiphytic lichens can reveal levels of trace elements in
the ambient air. This study assessed the trace elements in
lichen species Pyxine cocoes found in the urban and periurban areas of Kolkata. Trace elemental analysis was carried
out using energy-dispersive X-ray fuorescence and protoninduced X-ray emission spectroscopy. Variable levels of elements like Mn, Fe, Cu, Zn, Cr, V and Pb, are detected in the
thalli of P. cocoes collected …
