Content and Distribution of Toxicants in Soils near the Torbeevo Solid Waste Landfill in Moscow Oblast

Abstract

In this paper, the contents of nitrates, chlorides, mobile phosphates, petroleum products (PPs), and polycyclic aromatic hydrocarbons (PAHs) in soils at different distances (100, 200, 300, 750 m) from the Torbeevo (the Lubertsy region of Moscow oblast) solid waste landfill (SWL) along two rhumb lines are determined. The distribution of toxicants in the profiles of soddy–podzolic and soddy–gleyey soils near the landfill is considered. The study reveals the alkalization of the medium in the upper soil layer at a distance of 100–200 m from the landfill, contamination of roadside zones with petroleum products, and multiple excess of the background PAH content and benz(a)pyrene maximum permissible concentration at a distance of 100 m from the landfill near a road. For high-molecular PAHs, the contamination halos extend to 750 m from the SWL.
