The article describes the research on the retention capacity of two mountain catchments in the Polish Carpathian Mts. These are the catchments of the Czarna Woda and Biała Woda streams. These catchments are adjacent, have a similar area (about 11 km2 each), but are geograph-ically diverse. Their geomorphology, hydrographic network, soil water permeability and land use were analyzed. The Czarna Woda...
The extraction of minerals, including fossil fuels, is a licensed activity. In the case of strategic fossil fuels owned by the state, such as hard coal, lignite, crude oil, natural gas, a license is issued by the minister responsible for the environment.

Leachability of chemical substances from waste produced during fuel combustion in a power plant has been investigated. The aim of the research was to identify the chemical composition of eluates obtained from fly ashes and slags subjected to the leaching test. The results of leaching tests indicate potential environmental hazards related to the migration of chemical substances. Migration can occur...
