Research was carried out on the basis of long experience in the small plot of gray forest loam soil to be extended in a systematic pollution agroecotopes by lead, cadmium, zinc. The set of changes in the properties of microbial coen of gray forest loam soil in condition of contamination ecotops with pollutants was ascertained. With the growth concentration of lead, cadmium, zinc in gray forest loam soil there was a decrease in the activity of cellulose-digesting microorganisms, inhibition of soil respiration rate, and a trend for increasing of nitrifying microorganisms. Violation of the natural concentrations of heavy metals in the gray forest soil was accompanied by changes in the species composition of micromycetes. The excess of toxicants natural background caused an additional increase in the number of pathogenic species of the genus Fuzarium, Zygomycetes family, in particular, species Rizopus and the appearance of «melanization soil» effect.

Introduction. Propolis is a natural material whose extracts indicate numerous biological activities, including antifungal, antibacterial, antioxidant and anticancer. Phenolic compounds (flavonoids as well as phenolic acids and their esters) are one of the most frequently mentioned group of propolis components responsible for the biological activity of propolis extracts. Another group of components identified in propolis is elements, including macro- and microelements as well as heavy metals. Aim. The aim of the study was to determine the biological activity of the ethanolic propolis extract originated form Warmian-Masurian Voivodeship against moulds and to analyze concentration of selected flavonoids and elements present in the extract. Material and methods. The biological activity of the propolis extract obtained from a raw propolis originated from Warmian-Masurian Voivodeship against moulds was determined by dilution in nutrient solution. The content of selected flavonoids (apigenin, pinocembrin, kaempferol and galangin) in the propolis extract was determined using ultra-performance liquid chromatography photodiode array detection tandem mass spectrometric method. The concentration of elements in the propolis extract was analyzed by flame atomic absorption spectrometry. Results. The propolis extract was characterized by activity against all tested fungal strains. It showed the highest activity towards Chaetomium globosum and Penicillium cyclopium. Among analyzed flavonoids, the highest concentration in the propolis extract was determined for pinocembrin. In addition, high concentrations of Na, Mg, K, Ca and Fe were found in the propolis extract, and no toxic heavy metals were found. Conclusions. The ethanolic propolis extract of national origin shows biological activity against tested moulds and it is a valuable source of flavonoids, as well as macro- and microelements.

The article provides an ecological assessment of the impact of heavy metals on the biological properties of meadow chestnut trees in the southeast of Kazakhstan. The paper presents data on the study of the effect of heavy metals on the biological activity of soils. A review of literature data on the content of heavy metals in the environment is given, and the negative impact of some of them on the biological properties of meadow-chestnut soil is described. The species of soil invertebrates were identified, as well as soil enzymes that should be used as bioindicators for monitoring the contamination of meadow-chestnut soils with heavy metals. The results obtained will expand knowledge about changes in the biological activity of meadow-chestnut soils under the influence of HM pollution in the ecosystems of southeastern Kazakhstan.
