  1. 21. Effects of drought on waterchemistry in a boreal streamnetwork

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Enrique Gómez de Salazar Martínez; [2021]
    Keywords : : drought; boreal streams; Krycklan Catchment Study; land cover; biogeochemistry;

    Abstract : Hydrological drought at high latitudes represents a rising environmental hazard induced byglobal climate change. Yet, we still know little about how drought events influence thebiogeochemistry of boreal streams. READ MORE

  3. 22. Carbon Filters for Drinking Water Treatment – How Flow Rate and Empty Bed Contact Time Influence the Performance

    University essay from KTH/Kemiteknik

    Author : Wilma Bäckström Nilsson; [2021]
    Keywords : Carbon filter; GAC; BAC; Biofilm; Flow rate; NOM; EBCT; Kolfilter; GAC; PAC; biofilm; flödeshastighet; NOM; uppehållstid;

    Abstract : Dricksvatten är en essentiell del av ett hållbart samhälle. Därför är det viktigt att säkerställa säkert dricksvatten genom fungerande vattenreningsverk. En viktig förorening att behandla är NOM, som i sig är ofarligt men som kan producera farliga föroreningar. En teknik som används för behandling av NOM är kolfiltrering. READ MORE

  4. 23. Development and Testing of a Hydro-Chemical River MixingModel to Investigate Sources of Carbon and Mercury in the Mackenzie River Basin, Canada

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Torbjörn-Johannes Erikson; [2020]
    Keywords : mercury; Hg; POC; DOC; Mackenzie River; kvicksilver; Hg; DOC; POC; Mackenziefloden;

    Abstract : Mercury, Hg, is found in Arctic biota in alarming quantity, posing a potential health risk for the local population. It is believed that the large Arctic rivers contribute to this. The Mackenzie River annually transports approximately 325 km3 water to the Arctic Ocean, which is ca 10% of the freshwater received. READ MORE

  5. 24. Spatial patterns of zooplankton communities In Swedish mountain and boreal lakes.

    University essay from

    Author : Juan Manuel de la Quintana; [2020]
    Keywords : Lake; zooplankton; phytoplankton; DOC and DIN:TP.;

    Abstract :     Zooplankton is crucial for lake ecosystems as it is an important component in most of the food webs of these ecosystems. However, environmental changes have caused reductions in ecosystems nutrients and stoichiometry, which directly affects phytoplankton’s development and quality. READ MORE

  6. 25. Impact of different catchments on the Brownification of Lake Bolmen

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Kaela Chileshe; [2020]
    Keywords : Brownification; dissolved organic carbon DOC ; Iron Fe ; water colour; landscapes; climate change;

    Abstract : Increased DOC and Fe concentrations from terrestrial landscapes has led to the browning of boreal surface waters. The negative societal and ecological impacts of brownification are increased cost of water purification, increased presences of algae and cyanobacteria, loss of ecosystem services and reduced recreational value.
