  2. 11. Application of Passive DOAS for Studies of Megacity Air Pollution and Volcanic Gas Emissions

    Author : Mattias Erik Johansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Optical Remote Sensing Techniques offer the opportunity to, in real-time, obtain line averaged measurements of gases in the lower and upper atmosphere. These techniques easily offer themselves to automatization, which increases their usability for e.g. READ MORE

  4. 12. The fate of airborne lead pollution in boreal forest soils

    Author : Jonatan Klaminder; Ingemar Renberg; John G. Farmer; Umeå universitet; []
    Keywords : Air pollution; lead; lead isotopes; peat; forest soil; forest plants;

    Abstract : Lead has a more than three-millennia-long pollution history in Europe. Metal production, burning of coal and use of leaded petrol resulted in a significant pollution of the atmosphere. As a consequence of atmospheric fallout, the Swedish boreal forest is strongly contaminated by airborne lead pollution. READ MORE

  5. 13. Born in fire, borne by air : Source attribution and physicochemical characterization of ship and ambient aerosols in the Baltic region

    Author : Stina Ausmeel; MERGE: ModElling the Regional and Global Earth system; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anthropogenic air pollution; aerosol; black carbon; plumes; ship emissions; absorption; source apportionment; climate; Fysicumarkivet A:2020:Ausmeel;

    Abstract : Aerosol emissions from anthropogenic activities cause detrimental health effects and affect the climate system. Combustion is a large source of airborne fine particulate matter (PM2.5) and the uncertainties of the climate role of these emissions are still large. READ MORE

  6. 14. Isotope-based constraints on sources and processing of black carbon, carbon monoxide, and brown carbon in South Asia

    Author : Sanjeev Dasari; Örjan Gustafsson; August Andersson; Jos Lelieveld; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; South Asia; Air Pollution; Short-Lived Pollutants; Atmospheric Abundance; Model-Observation Mismatch; Radiocarbon; Stable Isotopes; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The highly populated South Asian region is facing rapid economic growth and urbanization. Here, both climate- and health-affecting atmospheric agents such as light-absorbing aerosols black carbon (BC) and brown carbon (BrC), trace gas carbon monoxide (CO), are often found in relatively high levels compared to in other regions.

  7. 15. Consequences of Poor Housing : Essays on Urban and Health Economics

    Author : Fredrik Hansson; Matz Dahlberg; Che-Yuan Liang; Aline Bütikofer; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Urban; health; education; in utero; pollution; radiation; uranium; radon; housing prices; happiness; well-being; urbanization; growth; Economics; Nationalekonomi;

    Abstract : Essay I: Research shows that low fetal doses of radiation from nuclear catastrophes and atmospheric test bombings of nuclear weapons cause cognitive birth defects. These events are uncommon and the radioactive isotopes they create rarely reach harmful levels in nature. READ MORE
