Abstract - Honey was proven to be a highly sensitive bioindicator for estimation of the environmental pollution with SO2. A bee monitoring net consisting of 32 apiaries and covering an area of about 700 km2 was configured surrounding the Sostanj coal-fired power plant. The results of investigations revealed that the amount of sulphate determined in honey from this area correlated with total yearly emissions of SO2 observed by an electronic monitoring. When exhaust gases at the power plant were purified, a corresponding decrease in the amounts of sulphate in honey was observed. The proposed bee monitoring net is an example of using biomonitoring for tracing environmental pollution, which could be also applied to estimate the impact of NOx gases or to trace other pollutants.
