  1. 6. Spatiotemporal reconstructions of black carbon, organic matter and heavy metals in coastal records of south-west Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Marcus Rudolf; [2016]
    Nyckelord :organic matter; spheroidal carbonaceous particles; black carbon; geology; physical geography; Ecosystem analysis; heavy metals; coastal sediments; Sweden; Earth and Environmental Sciences;

    Sammanfattning : This study presents reconstructions of black carbon (BC), including spheroidal and amorphous carbonaceous particles (SCP and ACP), organic matter (OM; total organic carbon, TOC; total nitrogen, TN; total sulfur, TS), and heavy metals (Fe, Zn, Pb, Cu, As and Hg) in coastal sediments off the south-west coast of Sweden. Sediment records from eight stations along a north-south transect off the south-west of Sweden were retrieved. LÄS MER

  3. 7. Miljö- och humanpåverkan av svavel som fungicid vid ekologisk äppelodling

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Anna Lundström; [2015]
    Nyckelord :svavel; fungicid; växtskyddsmedel; Kumulus DF; miljöpåverkan; humanpåverkan;

    Sammanfattning : Svavel som fungicid är sedan långt tillbaka mycket känt och används mycket runt om i världen. Det får användas i många olika grödor och även i ekologisk odling, då den bland annat anses vara en naturlig substans. LÄS MER

  4. 8. Reduction of Fine Particle and Deposit Forming Alkali by Co-Combustion of Peat With Wood Pellets in 150 kWth Grate Firing Boiler

    Master-uppsats,

    Författare :Kiflom Gebrehiwot Nigusie; [2011]
    Nyckelord :Technology; Reduction of alkali and fine particle emission; Teknik;

    Sammanfattning : The objective of the present work was to demonstrate the possibilities to reduce the emission of fine particle forming alkali during co-combustion of wood with peat in a full scale (150 kW) grate fired boiler. For this purpose the particle emissions from a 150 kW district heating grate fired boiler situated in northern part of Kramfors, Sweden, were studied. LÄS MER
