  1. 21. Framtidens vattenvård : en kvantifiering av internbelastningen av fosfor i Vansjön och Nordsjön i Norduppland

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Caroline Agrillo; Jens Fölster Jens Fölster; [2021]
    Keywords : fosfor; internbelastning; eutrofiering; syrebrist; aluminiumbehandling; biomanipulation;

    Abstract : En kvantifiering av internbelastningen av fosfor gjordes i de eutrofierade sjöarna Vansjön och Nordsjön i Norduppland genom fysiokemisk mätning av vattnet och fraktionsanalys samt inkuberingsanalys av sediment. Mycket låga syrehalter mättes under vintern 2021 medan vattnet var övermättat på syre under våren detsamma året. READ MORE
