METHOD FOR REDUCTION OF HEAVY METAL CONCENTRATIONS IN SOILS OF URBAN TERRITORIES Russian patent published in 2018 - IPC B09C1/00 

FIELD: ecology.

SUBSTANCE: planting of park lawn grasses and wood species-remediators with subsequent removal of leaf litter from the cleared territory, includes the following operations: first, sowing of a mixture of lawn grasses tolerant to shading is carried out, then woody species of maple leaf and horse chestnut are planted as phytoremediators to maximize the coverage of the deep-contaminated soil with root systems in the horizontal and vertical direction. Large-leaved lindens are planted as a source of organic matter in the corners and in the center of the remediation park. In autumn, during a massive leaf fall of maple and chestnut, the foliage is collected and removed from the territory, and linden leaves are left in the remediation park.

EFFECT: reduction of toxic concentrations of heavy metals in a meter-thick soil.
