The content of heavy metals (HM) (lead, copper, zinc and cadmium) in pollen load and the degree of contamination with epiphytic microflora with regard to a collection area were determined. The correlation was found out between the content of heavy metals, quantitative and qualitative indices of micromycetes of epiphytic microflora of pollen load. Samples from apiaries in the Novosibirsk and Kemerovo regions were selected in July, the Zalesovsky district and Altai Krai in May and June 2004. As is shown, a collection area had no influence on the contamination extent of pollen load with fungous microflora. In the samples of pollen load Penicillium and Alternaria mainly dominated. A decrease in the extent of lead contamination promoted increasing, and copper contamination – declining the number of micromycetes in epiphytic microflora. The increase in the content of zinc in pollen load also resulted in increased species composition of micromycetes. The bacterial contamination of Bacillus cereus increased as copper increased in the content, it declined at cadmium contamination. It is concluded, that the increased number of some pollutants in pollen load (lead and cadmium) results in decreased number of other pollutants (fungous microflora, spores of B. cereus). A collection area influences indirectly on the contamination of pollen load with micromycetes.
