The active layer soils of Greenlandic permafrost areas can function as important sinks for volatile organic compounds

Permafrost is a considerable carbon reservoir harboring up to 1700 petagrams of carbon accumulated over millennia, which can be mobilized as permafrost thaws under global warming. Recent studies have highlighted that a fraction of this carbon can be transformed to atmospheric volatile organic compounds, which can affect the atmospheric oxidizing capacity and contribute to the formation of secondary organic aerosols. In this study, active layer soils from the seasonally unfrozen layer above the permafrost were collected from two distinct locations of the Greenlandic permafrost and incubated to explore their roles in the soil-atmosphere exchange of volatile organic compounds. Results show that these soils can actively function as sinks of these compounds, despite their different physiochemical properties. Upper active layer possessed relatively higher uptake capacities; factors including soil moisture, organic matter, and microbial biomass carbon were identified as the main factors correlating with the uptake rates. Additionally, uptake coefficients for several compounds were calculated for their potential use in future model development. Correlation analysis and the varying coefficients indicate that the sink was likely biotic. The development of a deeper active layer under climate change may enhance the sink capacity and reduce the net emissions of volatile organic compounds from permafrost thaw.

The 5-years assessment of air quality, the Norwegian experience. NILU OR

Guerreiro, C.; Bøhler, T.

NILU og GIOS utfører prosjektet "Strengthening the air quality assessment system in Poland, based on Norwegian experience".
Denne rapporten beskriver norsk erfaring i forbindelse med klassifisering av soner sett i sammenheng med øvre og nedre vurderingsterskler som beskrevet i Artikkel 5 i EU-Direktivet 2008/50/EC og Artikkel 4 i Direktivet 2004/107/ EC. Dette er basert på de seneste vurderinger av luftkvalitet utført i Norge og gir en oversikt over tilgjengelig relevant informasjon og metoder som NILU foreslår brukt for en slik evaluering. En kort beskrivelse av Norges soneinndeling for vurdering av luftkvaliteten og målenettverk er også beskrevet.

Thallium Pollution in Europe Over the Twentieth Century Recorded in Alpine Ice: Contributions From Coal Burning and Cement Production

Legrand, Michel; McConnell, Joseph R.; Preunkert, Susanne; Bergametti, Gilles; Chellman, Nathan J; Desboeufs, Karine; Stohl, Andreas; Eckhardt, Sabine; Plach, Andreas

Emission inventories indicate that thallium, a highly toxic metal, is emitted during coal burning and cement production. These estimates have been established only for the 1980s and 1990s but up to now they have not been compared to long-term observations. Here we used alpine ice cores to document thallium pollution over Europe since ∼1850. Ice-core thallium concentrations increased from 1890 to 1910, and decreased after 1965 to concentrations that were half 1890 levels. Comparison of ice-core trends, estimated past emissions, and state-of-the-art atmospheric aerosol transport modeling suggest that coal burning was responsible for thallium pollution in Europe, particularly from 1920 to 1965 because of high coal consumption at that time. The subsequent decline resulted from decreased coal consumption and reduced emissions following technological improvements. The ice-core data suggest that the rapid growth of cement production that took place in Europe after 1950 had a limited impact on thallium pollution.
