Municipal solid waste landfills as a source of mycotoxins contamination in soil

Abstract

The authors analyse the results of mycological studies of the soil of one of the largest solid waste landfills in the Moscow region - the Salaryevo solid waste landfill. The agroecological and geochemical characteristics of the contaminated soil are explored. The authors studied the phytotoxicity of soil fungi, using Pisum sativum L as an object of analysis. The number of microscopic fungi in the contaminated soil increased 7 times, the phytotoxic fungi of the genus Alternaria, were 1.8 times higher than the reference level. Penicillium decreased by almost 30%. In many soil samples, fungi of the genus Fusarium were found. An increase in the number of fungi of the genus Alternaria had phytotoxic effect: in pea seedlings (Pisum sativum L.), a slower growth of roots and seedlings was observed.
