    Sammanfattning : Nowadays, the issue of global warming and related environmental problems got widespread awareness among scientific society, politics, the industry as well as it has affected our everyday life. The reason for such a negative impact on the atmosphere is attributed mainly to human activities. LÄS MER

  3. 2. Determination of Volatile Hydrocarbons in Urban Air

    Författare :Lars Löfgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; arenes; hydrocarbons; environment; alkenes; motor traffic; photochemical oxidant formation;

    Sammanfattning : In the complex hydrocarbon mixture in urban air, the alkenes and arenes are of particular interest with respect to impact on health and environment. Knowledge of hydrocarbon concentrations in urban air is essential for the assessment and prevention of health hazards and photochemical oxidant formation. LÄS MER

  4. 3. Carbon gas biogeochemistry of a northern peatland - in a dynamic permafrost landscape

    Författare :Kristina Bäckstrand; Patrick M. Crill; Torben R. Christensen; David Bastviken; Kimberly P. Wickland; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbon balance; Carbon exchange; Peatland; Subarctic; Climate change; Earth sciences; Geovetenskap; geokemi; Geochemistry;

    Sammanfattning : This thesis is about biogeochemical processes of a northern peatland and their importance as a link between the climate and the terrestrial system. Increased temperatures on a global level, and particularly in the Arctic, have led to melting permafrost and changes in hydrology. LÄS MER
