Закономерности пространственного распространения тяжелых металлов в донных осадках некоторых озер национального парка «Себежский»

Abstract

At the beginning of monitoring of water bodies of specially protected natural Sebezhsky National Park (Sebezhskoye, Orono and Beloe lakes) was made a decision to study bottom sediments. The selection of non-stratified samples of surface bottom sediments makes it possible to determine the current, latest in time, anthropogenic impact on the studied water bodies. As the main indicator of anthropogenic impact was chosen the content of heavy metals and metalloids (Cu, Cr, Zn, Pb, Ni and As).
