  1. 1. Anthropogenic influence on climate through changes in aerosol emissions from air pollution and land use change

    University dissertation from Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Author : Juan Camilo Acosta Navarro; Ilona Riipinen; Annica M.L. Ekman; Hans-Christen Hansson; Risto Makkonen; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; Air quality; Land use; General circulation; Atmosphere-Ocean interactions; Aerosol climate effects; Earth system modelling; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Particulate matter suspended in air (i.e. aerosol particles) exerts a substantial influence on the climate of our planet and is responsible for causing severe public health problems in many regions across the globe. READ MORE

  2. 2. Investigating parameters governing liquid-phase cloud activation of atmospheric particles

    University dissertation from Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Author : Maryam Dalirian; Ilona Riipinen; Ottmar Möhler; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; CCN activation; surface tension; coated aerosols; black carbon; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Aerosol-cloud interactions are one of the main sources of uncertainties in modeling and predicting the Earth’s climate. To overcome this uncertainty, we need to improve the understanding about the processes and parameters defining how aerosol particles turn into cloud condensation nuclei (CCN) or ice nuclei (IN) to produce cloud droplets or ice crystals.

  3. 3. Modeling the global fate and transport of perfluoroalkylated substances (PFAS)

    University dissertation from Stockholm : Institutionen för tillämpad miljövetenskap (ITM)

    Author : James M. Armitage; Ian T. Cousins; Michael S. McLachlan; David Ellis; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; perfluoroalkylated substances; global-scale; fate and transport; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Perfluoroalkylated substances (PFAS) are persistent contaminants that are widely distributed in the global environment. Despite the fact that these chemicals have been manufactured and used for over 50 years, there has been little scientific and regulatory interest until very recently. READ MORE

  4. 4. Integrating biochemical and growth responses in ecotoxicological assays with copepods

    University dissertation from Stockholm : Institutionen för tillämpad miljövetenskap (ITM)

    Author : Ulrika Dahl; Magnus Breitholtz; Peter Matthiessen; ; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry Environmental chemistry Environmental toxicology; NATURVETENSKAP Kemi Miljökemi Miljötoxikologi; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The understanding of effects of chemical exposure in nature is lagging behind. Predictions of harmful effects of chemicals on aquatic organisms rely mainly on ecotoxicity tests. READ MORE

  5. 5. Measurement and source apportionment of ubiquitous soot black carbon in sediments

    University dissertation from Stockholm : Institutionen för tillämpad miljövetenskap (ITM)

    Author : Marie Elmquist; Örjan Gustafsson; Per Andersson; Wulf Amelung; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The pyrogenic particles formed from incomplete combustion of organic matter are often termed black carbon (BC) and they partake in many important biogeochemical processes. For instance, BC in water and sediment affects the solid-water partitioning of hydrophobic organic pollutants reducing their bioavailability. READ MORE
