  1. 16. Biological Treatment of Oily Sludge and Sediments

    Author : Mait Kriipsalu; Chalmers tekniska högskola; []
    Keywords : bioremediation; refinery; aerobic biotreatment; flocculation-flotation unit FFU ; petroleum hydrocarbons; oily sludge; static biopile; PAHs; sediments;

    Abstract : AbstractOily sludge, generated in refineries or in other industrial sectors, and oil-containing sediments, removed from water bodies during remediation works, pose an environmental problem. A common feature between both is their high water content, and variable content of organic and inorganic contaminants, which complicates their treatment. READ MORE

  2. 17. Occurrence and environmental risk assessment of antifouling paint biocides from leisure boats

    Author : Maria Lagerström; Ann-Kristin Eriksson Wiklund; Erik Ytreberg; Kent Salo; Andrew Turner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antifouling paint; XRF; leisure boat; recreational boating; copper; zinc; tributyltin; organotin compounds; risk assessment; biocide; metals; release rate; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The use of biocidal antifouling (AF) paints is the most common way to prevent fouling on leisure boat hulls. The main aim of this thesis was to investigate the pathways through which AF biocides, past and present, may reach the environment through their use on leisure boats and to improve the risk assessment of biocidal AF paints intended for amateur use.

  3. 18. Future trends in urban stormwater quality : effects of changes in climate, catchment characteristics and processes and socio-economic factors

    Author : Matthias Borris; Lian Lundy; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : Climate change and progressing urbanization cause numerous environmental concerns, including the impacts on urban drainage. Such impacts were addressed during the last two decades with focus on hydraulic overloading of drainage systems and the means of overload remediation by stormwater management. READ MORE

  4. 19. Assessment of stormwater and snowmelt quality based on water management priorities and the consequent water quality parameters

    Author : Helen Galfi; Maria Viklander; Jiri Marsalek; Helene Österlund; Jon M. Hathaway; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stormwater quality; indicator bacteria; water quality assessment; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

    Abstract : Stormwater and snowmelt pollution contributes to degradation of quality of the receiving waters. For assessing such impacts, it is effective to focus on specific causes of degradation, as done in this study of the quality of stormwater and snowmelt discharges into the receiving waters serving for supply of raw drinking water and water-based recreation.

  5. 20. Transport of Arsenic and Heavy Metals to Lake Poopó - Bolivia Natural Leakage and Anthropogenic Effects

    Author : Maria Garcia Moreno; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogeology; Naturvetenskap; Natural science; Miljöstudier; Environmental studies; Poopó Lake; heavy metals; Bolivia; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi;

    Abstract : Bolivia, a country located in the center of South America, has in the west part an Andean region, where the Poopó Lake is located. The area has many mineral resources, and thus since thousands of years,mining activity has had a large importance; however, mainly since colonial times, the extraction of these resources has been indiscriminate and the region of the Poopó Lake, has suffered the consequences of environmental contamination.
