| This paper presents a comprehensive analysis of the history of oil shale mining and combustion in northeastern Estonia, the formation of atmospheric influxes and spatio-temporal distribution of deposited impurities. The data calculated for the subsurface air layer and the distribution of impurities in lake sediments are in a very weak correlation. These show an important role of the subsurface turbulence, landscape topography, as well as the deposition pathways and processes of influxes into the lake. |
