  1. 21. Urban stormwater ponds: Evaluation of heavy metals and organic pollutants in stormwater and stormwater sediments

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Felix Karlsson; [2021]
    Keywords : Urban stormwater; Stormwater ponds; Stormwater sediment; Heavy metals; Organic pollutants;

    Abstract : Urban runoff is generated by precipitation of rain and snowmelt on impervious surfaces.  The increasing demand of urbanization causes contaminants to accumulate on roads,  roofs and pathways. In turn, as runoff wash off these surfaces, contaminants such as heavy metals, particles and organic pollutants end up in the stormwater. READ MORE

  3. 22. Evaluation of a gross pollutant trap-biofilter stormwater treatment train : The Role Of Calcium Carbonate, Vegetation And Pre-Treatment Facility

    University essay from Luleå tekniska universitet/Arkitektur och vatten

    Author : Sofia Fahlbeck Carlsson; [2021]
    Keywords : Bioretention; stormwater; stormwater treatment; stormwater pollutants; heavy metals; phosphorus; Biofilter; dagvatten; dagvattenrening; dagvattenföroreningar; tungmetaller; fosfor;

    Abstract : Development of cities, new buildings and other impervious surfaces entails increased stormwater flows, volumes and pollutant loads. Heavy metals, nutrients, sediments and salt are common pollutants in stormwater. READ MORE

  4. 23. Investigation of Cu and Zn interactions with ilmenite during waste incineration

    University essay from

    Author : Elin Borgman; [2020-06-08T12:03:31Z 2020-06-08T12:03:31Z 2020 2019]
    Keywords : FactSage; copper; zinc; major ash elements;

    Abstract : In 2018, approximately 2.01 billion tons of waste was generated in the world. By 2050, this number is expected to increase drastically to 3.40 billion tons of waste annually as lower income countries develop and the world population increases (Kaz, Yao, BhadaTata, & Van-Woerden, 2018).

  5. 24. Temporal and spatial trends of heavy metal leakage from acid sulfate soils : Leakage of Ni, Zn, Cu and Fe to freshwater and marine sediments, North-eastern Sweden

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

    Author : Bella Blomkvist; [2020]
    Keywords : acid sulfate soils; leaching; Persöfjärden; sulfide oxidation; metal pollution;

    Abstract : Acid Sulfate soils (AS) are recognized for being a source of acidity in freshwaters in America, Europe, Australia, and Asia. Apart from the problematic acid leachate, AS soil serves as a possible source of toxic heavy metals in freshwaters, a problem which has received far less attention than problems related to acid leachate.

  6. 25. Cobalt and nickel concentrations in the Uppsala clay deposits : solubility and risk assessment

    University essay from SLU/Dept. of Soil and Environment

    Author : Ali Reza Sadeghi; [2020]
    Keywords : heavy metals; soil contanimation; geochemically active fraction; leaching test; guideline value; site-specific guideline value;

    Abstract : Heavy metals create a contamination problem in soils. Examples of heavy metals are Ni, Co, and Cu. Soil environment and minerals existing in the soil such as Fe and Mn oxides affect the presence of these heavy metals. In this thesis, the cobalt and nickel concentrations of selected soil samples from different locations in Uppsala were determined. READ MORE
