This book offers a comprehensive review of the current environmental conditions and chemical changes in Polish surface waters. Poland is situated in an area that was covered by glaciations in the distant past. The subsequent periods of glacial advance and retreat produced a continuous rejuvenation of the landscape, and the discharge of surplus water from this area was constantly transformed by morphological, climatic and hydrological changes.

Written by expert contributors, the book's respective chapters address the impact of current climatic conditions on the functioning of surface water reservoirs in Poland, while also exploring the country's hydrographic and hydrological network and the trophic state of its rivers and lakes, their eutrophication and threats. Particular attention is paid to sources of pollution, above all, the chemical pollution of water and sediments.

Together with the companion book Polish River Basins and Lakes Part II: Biological Status and Water Management , it provides students, environmental chemists, biologists, geologists, hydrologists and surface waters managers with authoritative information on Poland's current environmental status.

Outlines the environmental and chemical changes in Polish surface waters and sediments Examines the impact of climate change on the functioning of freshwaters in Poland Covers the trophic state of Polish lakes and rivers, their eutrophication and threats
