  1. 1. Lakes are browner in the south than in the north of Sweden despite similar levels of dissolved iron

    Magister-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Fredrik Lindgren; [2019]
    Nyckelord :Brownification; DOC; dissolved iron; humic lakes; sulphur deposition; absorbance; climate change;

    Sammanfattning : During recent decades many lakes have become browner in the northern hemisphere and more specific in Sweden. This process is called brownification. Brownification of lakes makes it more difficult to clean water to drinking water and may have negative ecological effects on biota. LÄS MER

  2. 2. Våtmarkens kapacitet - kan en våtmark optimeras för att minska såväl eutrofiering som brunifiering?

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Josefina Almén; [2019]
    Nyckelord :wetland; brownification; DOC; nutrients; water quality; Earth and Environmental Sciences;

    Sammanfattning : Due to changes in land use, as well as impacts from the climate change, our inland waters are now exposed to problems such as eutrophication and brownification. This complicates management to develop clean drinking water, as well as it leads to anoxic bottoms and reduces primary production. LÄS MER

  3. 3. The content, chemical state and accumulation of vanadium in a drill core of Alum shale from Kinnekulle

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Niklas Gunnarsson; [2019]
    Nyckelord :Alum Shale Formation; Alum shale; Kinnekulle; Vanadium; Inorganic chemistry; Oorganisk kemi; Chemistry;

    Sammanfattning : Exploitation of alum shale is a controversial subject in Sweden due to the history of pollution of the environment and groundwater, from past mining industries. The extraction of vanadium from alum shale is no different. Nevertheless the metal is a valuable resource used in tools, building, industries and aerospace materials. LÄS MER

  4. 4. Adsorption of micropollutants in wastewater using pulverized activate carbon - The influence of organic matter content and characteristics

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Anna Nicola Messinger; [2019]
    Nyckelord :Pulverised Activated carbon; PAC; UVA254; Wastewater treatment; Micropollutants; Activated carbon; Earth and Environmental Sciences;

    Sammanfattning : Wastewater is one of the biggest emission sources of organic micropollutants to the aquatic environment. Due to the negative effects of micropollutants on the receiving waters, advanced treatment steps are needed to reduce these emissions. Activated carbon is one promising approach. LÄS MER

  5. 5. Filter Materials for Sorption of Cu and Zn in Stormwater Treatment: A Batch Equilibrium and Kinetic study

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Arkitektur och vatten

    Författare :Per-Albin Norman; [2018]
    Nyckelord :Stormwater; Treatment; Metals; Sorbents; Batch equilibrium test; Isotherms; Kinetic test; Catch basin inserts;

    Sammanfattning : Urban stormwater is today recognized as a significant source of pollution that has contributed to the deterioration of water quality in lakes and streams. Of the pollutants, metals are commonly occurring in stormwater and can cause major damage when released into the receiving waters. LÄS MER
