Heavy metal air pollution is an important environmental problem. One of
the methods used to monitor pollution in air is the method of transplanting
lichen samples by the "bag technique". In this study, Pseudevernia furfuracea was used as a
bioindicator to determine the heavy metal level in the air of Çorum and to
generate an air pollution map of the city. The lichen samples were collected
from the Yapraklı Mountains in Çankırı in 2002 and transplanted to 8 different
stations in Çorum. Lichen samples were retrieved at two different periods in
three month intervals. Inductively Coupled Plasma (ICP) spectrometry (Varian
Liberty ICP-OES Sequential) was used to identify the heavy metals, such as copper (Cu), cadmium (Cd), manganese (Mn), nickel (Ni), lead (Pb) and
zinc (Zn) in the lichen samples. The chlorophyll a and b contents were determined
by using the modified DMSO (dimethyl sulfoxide) method. With these values
chlorophyll a+b, a/b and b/a were also calculated. According to the results of
the heavy metal analysis by the use of P.
furfuracea, air pollution levels in Çorum was detected. The reasons of
pollution can be stated as heavy traffic, industrial activities and heating
processes in the city. P. furfuracea
can be used as a bioindicator for pollution studies.
