FIELD: ecology.
SUBSTANCE: invention relates to environmental safety and can be used for treatment of heavy metals from man-made soil and agricultural lands. Preparation of extremely hazardous soil for its further purification by phytoremediation. Mixture of adsorbents of hydrophilic and hydrophobic nature, in ratio of 1:3, is added to the soil contaminated with heavy metals. Hydrophilic adsorbent used is vermiculite or clinoptilolite. Hydrophobic adsorbent used is stone activated carbon. For 30 days, the soil is humidified and aerated by loosening.
EFFECT: reduced content of pollutants to maximum permissible standards.
