  2. 1. Emissions of organic compounds from technosphere articles : Measurements and modeling of mass transfer from consumer goods and building materials to air and water

    Author : Tomas Holmgren; Peter Haglund; Martin Scheringer; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Emission; model; DINP; DINCH; TiBP; TPP; Vinyl flooring; flat screen displays; LCD screen; concrete; Abraham solvation parameters; Piringer equation; linear free energy relation;

    Abstract : This thesis describes the development of a generic model for predicting the emissions of organic compounds from materials used in the manufacture of various goods and products. Many products contain organic substances that are not bound to the matrix formed by their constituent materials and are thus able to dissociate from the material and become transferred into the surrounding environment.

  5. 3. On the chemical state and mobility of lead and other trace elements at the biogeosphere/technosphere interface

    Author : Mattias Bäckström; Gunnar Jacks; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lead; trace elements; traffic; shooting range; peat; sediments; speciation; biokemi; Chemistry; Kemi; Kemi; Chemistry;

    Abstract : Most inorganic contamination has occurred at the interface between the technosphere and the biogeosphere, even though atmospheric emissions have affected the entire globe. Several human activities now pose a substantial threat towards human health and the ecosystems. READ MORE

  6. 4. Growth versus the Environment - Is There a Trade-off?

    Author : Per Kågeson; Miljö- och energisystem; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; emissions reduction; material intensity; pollution control; sustainable development; resource depletion; environment; economic growth; energy; Environmental technology; Miljöteknik; kontroll av utsläpp;

    Abstract : This book shows that the intensity of use of energy and materials in OECD countries is diminishing over time despite falling metal and energy prices. Material demand is sometimes falling in absolute terms, but there are also a few examples of rapid growth. READ MORE

  7. 5. Flow-oriented studies for environmental management by local authorities : experiences from a regional substance flow analysis

    Author : Annica Lindqvist-Östblom; Linköpings universitet; []
    Keywords : flow-oriented studies; material flow analysis; substance flow analysis; interpretation; local authorities; regional authorities; environmental management; cadmium; sewage;

    Abstract : This thesis focuses on the issue of how to perform flow-oriented studies in order to become more useful for and adapted to local/regional authorities. Compared to traditional environmental monitoring and measurement of the state of the environment, flow-oriented studies are an attempt to broaden the approach to environmental concerns. READ MORE
