Airborne metals and SO2 monitored by epiphytic lichens in an industrial area,
Environmental Pollution,
17: 81-92
The epiphytic lichen Lecanora conizaeoides was used as a monitor organism of
airborne metals around an industrial area (a steelworks and an iron foundry) at
Frederiksvaerk, Denmark. Ca, Cd, Cr, Cu, Fe, Mg, Mn, Ni, Pb, V and Zn
were determined by atomic absorption spectrophotometry and K and Na by flame
emission techniques. SO 2 air pollution levels were estimated by the distribution of
lichen species with different SO 2 sensitivities.
A similar regional variation was found within the Frederiksvaerk …
