  1. 1. Aerosol–cloud interactions in a warming Arctic

    Författare :Linn Karlsson; Paul Zieger; Radovan Krejci; Annica M. L. Ekman; Birgit Wehner; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; aerosols; clouds; aerosol-cloud interactions; Arctic; climate; field studies; Environmental Sciences; miljövetenskap;

    Sammanfattning : Atmospheric aerosol particles are small liquid or solid particles suspended in the air. They are present in the atmosphere all around us and affect the planetary energy balance by scattering and absorbing radiation and by interacting with clouds. In model projections of future climate, aerosol–cloud interactions contribute a lot of uncertainty. LÄS MER

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

    Författare :Juan Camilo Acosta Navarro; Ilona Riipinen; Annica M.L. Ekman; Hans-Christen Hansson; Risto Makkonen; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; 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;

    Sammanfattning : 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. LÄS MER

  4. 3. In vitro and in vivo studies on the toxicology of di-n-butyl phthalate (DBP) : Effects on reproductive, endocrine, and immune systems

    Författare :Liselott Källsten; Oskar Karlsson; Paula Pierozan; Jonathan W. Martin; Jorma Toppari; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Dibutyl phthalate; Endocrine disrupting chemicals; Male reproductive health; Phthalates; Immunotoxicity; Toxicology; Steroidogenesis; Environmental Sciences; miljövetenskap;

    Sammanfattning : Chemical pollution is an increasing societal problem and has a major impact on human and environmental health. One important source of chemical pollution is plastic, which contains many different compounds with often largely unknown hazards. LÄS MER

  5. 4. Transport of perfluoroalkyl acids from the ocean to the atmosphere via sea spray aerosol

    Författare :Bo Sha; Ian Cousins; Matthew Salter; Jana Johansson; Jonathan P. Benskin; Cora Young; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Perfluoroalkyl acids; PFAAs; Per- and polyfluoroalkyl substances; PFAS; atmospheric transport; sea spray aerosol; industrial sources; Environmental Sciences; miljövetenskap;

    Sammanfattning : Perfluoroalkyl acids (PFAAs) are a subgroup of per- and polyfluoroalkyl substances (PFAS) that have been widely used in commercial and industrial applications. PFAAs are very persistent in the environment and some can bioaccumulate and have adverse health effects on human health. LÄS MER

  7. 5. Degradation Pathways of Dimethylmercury in Natural Waters

    Författare :Johannes West; Sofi Jonsson; Andrew Graham; Elena Gorokhova; Bridget Bergquist; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mercury; Marine; Degradation; Methylmercury; Aquatic; Environmental Sciences; miljövetenskap;

    Sammanfattning : Mercury (Hg) is a naturally occurring toxic trace metal whose release into the environment has been (and still is) exacerbated by human activities. The bioavailability of Hg is tied to its chemical speciation, with monomethylmercury (MMHg) being the primary form of Hg that bioaccumulates and biomagnifies. LÄS MER
