  1. 1. How brownification and eutrophication effects a drinking water source – with Lake Bolmen, Sweden, in focus

    University essay from Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Stina Stomberg; [2022]
    Keywords : brownification; eutrophication effects; drinking water; phytoplankton; Lake Bolmen; mesocosm; Earth and Environmental Sciences;

    Abstract : The ongoing human impact in form of deforestation, urbanization and intense agriculture is affecting the natural hydrology and our freshwater lakes negatively. Both eutrophication and brownification has seen to increase with the ongoing environmental change which can potentially have large impact on our freshwater ecosystems. READ MORE

  3. 2. Feeding brown algae and brown algae extracts from Saccharina Latissima to Broiler breeders : effects on transfer of antibodies and nutrients from hen to egg

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Stina Kling; [2021]
    Keywords : broiler; broiler breeder; brown algae; Saccharina Latissima; laminarin; prebiotic; transfer; antibodies; nutrients; iodine; chicken; egg quality;

    Abstract : Brown algae and extracts of algae have been proved to have prebiotic effects. Seaweeds grow very fast and underwater. This is good from a sustainable point of view since algae do not need fertilizers, freshwater or agricultural land for growth. Brown algae is rich in nutrients, vitamins and minerals, and has an especially high content of iodine. READ MORE

  4. 3. Kiselalgers anpassning till ljus : en jämförelse mellan Brachysira neoexilis och Eunotia incisa

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

    Author : Ylva Friheden; [2019]
    Keywords : Kiselalger; Bacillariophyceae; tillväxtsexperiment; ljusintensitet;

    Abstract : Syftet med denna studie är att undersöka ljuspreferenserna hos kiselalgerna Brachysira neoexilis (BNEO) och Eunotia incisa (EINC), alltså vid vilka ljusintervall de har störst tillväxt. I samband med vattenkvalitetsundersökningar så skulle kunskapen om hur ljus påverkar kiselalgernas tillväxt minska den osäkerhet som finns kring hur andra påverkansfaktorer, förutom näring och organiska ämnen faktiskt kan påverka vattenkvalitetsindex.

  5. 4. Combination of nanoparticles from polystyrene and the hormone 17alpha-ethinylestradiol (EE2) in water.

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Emma Nilsson; [2017]
    Keywords : water; nanoparticles; hormons; Plastic; Earth and Environmental Sciences;

    Abstract : Plastic materials and synthetic hormones are found in aquatic environments globally. Plastic in water can degrade to nanoparticles (NP) with special characteristics, in the environment nanoparticles and hormones have a proven effect on wildlife. READ MORE

  6. 5. Frigörelse av fosfor från färskt, fryst och torkat växtmaterial : ett laboratorieförsök för att öka förståelsen för fosfordynamiken inom växtodlingen

    University essay from SLU/Dept. of Soil and Environment

    Author : Jon Wessling; [2015]
    Keywords : fosforförluster; fosforutlakning; frysning; tining; ytavrinning; freezing; losses; phosphorus; plant material; residue; thawing;

    Abstract : Phosphorus is the single most potent contributor to eutrophication of freshwater and has also been shown to contribute to the toxic algae blooms in the Baltic sea. The dynamics and paths of losses of phosphorus from arable lands are not fully understood. It is known that phosphorus can be lost directly from plant material to water. READ MORE
