Abstract. Data on the content and distribution of some heavy metals (zinc, copper, lead and cadmium) in the soil layer of drained and anthropogenically transformed marshes of the central part of the Kirov region are presented. Studies were carried out in 2011–2016 on two drained marshes: “Zenginskoye” and “Karinskoye”. Studies have shown that the content of total and mobile forms of heavy metals in the peat of the surveyed marshes is insignificant and in general does not exceed the known standards of maximum permissible concentrations and the average background content in zonal sod-podzolic soils of the Kirov region. The involvement of drained marshes in economic activity leads to an increase in the content of heavy metals in the soil profiles of drained marsh soils. In areas occupied by crops and plantings of P. sylvestris and P. abies, the content of heavy metals is higher compared to the control area: zinc – by 5–18 times, copper – by 6–24 times, lead – by 2–4 times, and cadmium – by 3–5 times. Residual peat layers contain insignificant reserves of heavy metals. The residual peat of the Zenginskoye marsh contains significantly more heavy metals than the peat of the Karinsky massif. The content of heavy metals in the residual peat layers of these objects does not pose a danger to the environment with the possible subsequent involvement of drained bog biogeocenoses in agricultural and forestry use.
