The content of phytopathogenic fungi and the concentration of benz(a)pyrene in soil samples located near the oil refinery has been investigated. It has been found that in the vast majority of soil samples pathogenic micromicetes are represented by genera Fusarium, Rhizoctonia, Phytophthora, which have a negative effect on crops growth. The highest content of pathogenic micromycetes, amounting to10 CFU per 1 g of soil, was found in soil samples located directly on oil spill territory. It has been found that in an overwhelming number of soil samples, the concentration of benz (a) pyrene, which belongs to organic substances of grade I hazard, exceeds the MPC. The results of the study are consistent with earlier evidence that concentrations of pathogenic micromycetes and benz (a) pyrene are higher in anthropogenic-afected soils. This is due to the negative effect of oil hydrocarbons and benz (a) pyrene on useful soil microflora, and further settlement of the released ecological niche by pathogens. The company is given recommendations on the use of soil for cultivating technical crops or its exclusion from agricultural use.
