  1. 1. Impact of residential wood combustion on urban air quality

    Författare :Patricia Krecl; Christer Johansson; Johan Ström; Tami Bond; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; residential wood combustion; air quality; aerosols; black carbon; polycyclic aromatic hydrocarbons; particulate matter; particle size distributions; source apportionment; positive matrix factorization; compound-specific radiocarbon analysis; Earth sciences; Geovetenskap; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Wood combustion is mainly used in cold regions as a primary or supplemental space heating source in residential areas. In several industrialized countries, there is a renewed interest in residential wood combustion (RWC) as an alternative to fossil fuel and nuclear power consumption. LÄS MER

  2. 2. Transport, degradation and burial of organic matter released from permafrost to the East Siberian Arctic Shelf

    Författare :Lisa-Marie Bröder; Örjan Gustafsson; Tommaso Tesi; Elizabeth Canuel; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; organic carbon; marine sediments; East Siberian Sea; Laptev Sea; cross-shelf transport; degradation rate constants; carbon isotopes; terrestrial biomarkers; HMW wax lipids; lignin phenols; compound-specific radiocarbon analysis; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Permafrost soils in the Arctic store large quantities of organic matter, roughly twice the amount of carbon that was present in the atmosphere before the industrial revolution. This freeze-locked carbon pool is susceptible to thawing caused by amplified global warming at high latitudes. LÄS MER
