Environmental Impacts—Freshwater Biogeochemistry [PDF]

, 2015
Climate change effects on freshwater biogeochemistry and riverine loads of biogenic elements to the Baltic Sea are not straight forward and are difficult to distinguish from other human drivers such as atmospheric deposition, forest and wetland management , eutrophication and hydrological alterations. Eutrophication is by far the most well-known factor
