Binding phosphorus into sediment

Binding phosphorus into sediment – Stockholm university

In the project, three pilot examples with marl/ limestone residue application to phosphorus-rich bottom sediments will be implemented in coastal bays in Sweden and Finland. The pilots have started with a development phase, risk assessments and selecting of the pilot sites, after which the measure will be implemented. After application, the effects of the measure on phosphorus concentrations as well as on sediments and biota will be assessed. If the pilot tests are successful, the results will be compiled into guidelines for marl application as a method for binding phosphorus to bottom sediments in the Baltic Sea region. Read more about the treatment of marl and about our visit to Cementa AB, where the marl is treated.
