  1. 1. Tungmetaller i dagvattendammar : en jämförelse mellan beräknade och uppmätta årsmedelhalter i inkommande dagvatten

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

    Author : Mathias Andersson; [2019]
    Keywords : Germans formel; StormTac; flödesproportionell vattenprovtagning; tungmetaller; dagvatten;

    Abstract : Dagvatten som rinner längs hårdgjorda ytor i stadsmiljöer kan föra med sig tungmetaller och andra föroreningar från ytorna. Vanligtvis transporteras det förorenade dagvattnet via led- ningsnäten till en recipient där det riskerar att förorena sjöar och vattendrag. READ MORE

  3. 2. Evaluation of stimulated reductivedechlorination in situ of chlorinatedsolvents at a site in Huddinge : using principal component analysis, partialleast square regression and degradation

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Karin Ljungberg; [2018]
    Keywords : Reductive dechlorination; DNAPL; stimulated bioremediation; chlorinated solvents; Reduktiv deklorering; DNAPLS; stimulerad biologisk behandling; klorerade lösningsmedel;

    Abstract : The method of using stimulated reductive dechlorination when remediating sites contaminated with chlorinated solvents is not unusual, but not many studies have been done on the overall process outside of a controlled environment. In order to investigate the process, principal component analysis (PCA) and partial least square (PLS) regression was used to identify the most important parameters for the degradation of the chlorinated solvents.

  4. 3. Multidisciplinary perspectives on a natural attenuation zone in a PCE-contaminated aquifer

    University essay from Lunds universitet/Geologiska institutionen

    Author : Robin Jansson; [2018]
    Keywords : DCIP; groundwater chemistry; Tetrachlorethene; PCE; natural attenuation; Earth and Environmental Sciences;

    Abstract : The old dry-cleaner in Hagfors, is one of the most seriously tetrachloroethene (PCE) contaminated sites in Sweden. Ever since the pollution was discovered in the groundwater in the 1990s, the site has undergone remedi-ation two times with limited success. READ MORE

  5. 4. XRF-as a tool for monitoring of biocide load in boatyards : Case study on two boatyards in Lake Mälaren

    University essay from Stockholms universitet/Institutionen för miljövetenskap och analytisk kemi

    Author : Matz Norling; [2015]
    Keywords : ;

    Abstract : The aim of this study was to assess the suitability of a special application to a Field Portable, handheld X-Ray Fluorescence (FPXRF) analyzer for monitoring of boatyards with focus on biocide load on boat hulls. In addition, the instrument was used for investigating the spatial distribution of contaminants in soil and sediments. READ MORE

  6. 5. Submarine slope instability as a cause of contaminated sediment dispersal in Ångermanälven, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Hannes Berg Wiklund; [2015]
    Keywords : Submarine landslides; contaminated sediments; weak layers; Ångermanälven; Undervattenskred; förorenade sediment; svaga lager; Ångermanälven;

    Abstract : This study aims at providing results for the analysis of the stratigraphy underlying contaminated sediments in Ångermanälven. The contaminated sediments, containing heavy metals and persistent organic pollutants, are derived from wastewater discharged into Ångermanälven from nearby paper and pulp industries. READ MORE
