Abstract
Landfills cause significant technogenic pressure on the environment, being the center of depositing large volumes of hazardous materials in a relatively small area. Interacting with each other they form hazardous substances and compounds. In this study, we describe three genetic soil horizons that are within the impact zone of the landfill of a city of millions of people. It was established that the distribution of mobile forms of heavy metals according to the profile of the studied soils tended to gradual decrease with depth. When describing the genetic horizons of three profiles located in the impact zone of the landfill, it was established that the content of heavy metals in them does not exceed the MPC, except for Pb. The soil at the foot of the landfill turned out to be the most contaminated with heavy metals (profile No. 3). The activity of micromycetes in this soil was the lowest here. In general, all soils in the impact area of the landfill are impoverished in micromycete distribution. The taxonomic composition of mycelial fungi and the identified species’ ecological and biological characteristics indicate significant ecosystem pollution by household waste.
