  1. 1. Industrial metabolism : The emerging landscape of heavy metal immission in Sweden

    Författare :Bo Bergbäck; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Since the turn of this century, technological development has drastically increased the industrial consumption of toxic metals. Once dispersed in the environment, the metals cannot be degraded but will be accumulated in soil or sediment sinks. Thus, environmental effects of heavy metal pollution tend to be permanent. LÄS MER

  3. 2. Material metabolism of residential buildings in Sweden: Material intensity database, stocks and flows, and spatial analysis

    Författare :Paul Gontia; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; clustering algorithms; single-family buildings; bottom-up modeling; residential buildings; human settlements; spatial analysis; multi-family buildings; material flow accounting; construction materials; material intensity database; material stock; urban stock; built environment; anthropogenic metabolism;

    Sammanfattning : Construction materials are used for the expansion and maintenance of the built environment. In the last century, construction material stock has increased globally 23-fold. LÄS MER

  4. 3. Land use effects on greenhouse gas emissions from boreal inland waters

    Författare :Marcus Klaus; Jan Karlsson; Peter Staehr; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; greenhouse gas; boreal forest; carbon cycling; whole-ecosystem experiment; limnology; metabolism; forest clearcutting; nitrogen enrichment;

    Sammanfattning : Anthropogenic activities perturb the global carbon and nitrogen cycle with large implications for the earth’s climate. Land use activities deliver excess carbon and nitrogen to aquatic ecosystems. In the boreal biome, this is mainly due to forestry and atmospheric deposition. LÄS MER

  5. 4. Uptake, turnover and distribution of chlorinated fatty acids in aquatic biota

    Författare :Helena Björn; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; porpoise; fish; metabolism; food chain; respiration; membrane; phospholipid; chlorohydrins; lipid; Ecology; Ekologi;

    Sammanfattning : Chlorinated fatty acids (ClFAs) are the major contributors of extractable, organically bound chlorine in fish lipids. A known anthropogenic source of ClFAs is chlorine bleached pulp production. Additional anthropogenic sources may exist, e.g. LÄS MER

  7. 5. Polybrominated dibenzo-p-dioxins : Natural formation mechanisms and biota retention, maternal transfer, and effects

    Författare :Kristina Arnoldsson; Peter Haglund; Patrik Andersson; Walter Vetter; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polybrominated dibenzo-p-dioxins; PBDDs; Baltic Sea; uptake; retention; maternal transfer; metabolism; bioavailability; natural formation; precursor; bromoperoxidase; bromophenol; photochemical transformation; oxidative coupling; hydroxylated polybrominated diphenyl ethers; Chemistry; Kemi; analytisk kemi; Analytical Chemistry;

    Sammanfattning : Polybrominated dibenzo-p-dioxins (PBDD) and dibenzofurans (PBDF) are a group of compounds of emerging interest as potential environmental stressors. Their structures as well as toxic responses are similar to the highly characterized toxicants polychlorinated dibenzo-p-dioxins. LÄS MER
