Summary: | Bor and the surroundings (Eastern Serbia) have been known for exploitation
and processing of sulphide copper ores for more than 100 years. Emissions of
waste gases and particulate matter rich in heavy metals are characteristic
for pyrometallurgical production of copper. Long-term measurement results
(2005-2008) indicate an increased sulphur dioxide level in the
urban-industrial zone of Bor since it is closest to the copper smelter which
is a dominant source of air pollution in the studied area. Average annual
sulphur dioxide concentrations at four measuring sites in the
urban-industrial zone exceeded the maximum allowable value of 50 μg/m3.
However the maximum allowable value of the total atmospheric depositions (200
mg/m2/day on an annual basis) exceeded only at two of 15 measuring sites in
the urban-industrial and rural zone. The highest annual deposition rate of
sulphates from deposition was detected in the urban-industrial zone. Since
the maximum permitted value for sulphates is not defined by the Serbian
Regulations, the extent of the pollution cannot be discussed. Since the
environment can continuously be polluted through the wet and dry deposition,
biomonitoring by moss was conducted, which revealed significantly higher
concentrations of total sulphur in moss in the urban-industrial zone,
compared to the background zone. The obtained results confirm the reliability
of moss as a bioindicator of ambient pollution. Higher total S concentration
in soil samples was noted at the rural site (Ostrelj) located in the close
vicinity of two tailing ponds. [Projekat Ministarstva nauke Republike Srbije,
