  1. 11. DNA adductomics: Method development and integration in biological effect monitoring

    Författare :Giulia Martella; Elena Gorokhova; Hitesh V. Motwani; Brita Sundelin; Gunnar Boysen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA adducts; Nucleic acids; High-resolution mass spectrometry; Data-independent acquisition; Biological effect monitoring; Environmental contaminants; Biomarkers; Amphipods as sentinel species; Environmental Sciences; miljövetenskap;

    Sammanfattning : Environmental omics can provide informative biomarkers for identifying pathologies or physiological responses to environmental change. Nucleic acid adductomics, one of the newest omics techniques, is particularly well suited for assessing exposure and effects of environmental contaminants because the technique can capture modifications at the (epi)genome level.

  3. 12. Micro-by-micro interactions : Aggregation dynamics, biofilms, and ecotoxicological impacts of suspended solids

    Författare :Sophia Reichelt; Elena Gorokhova; Rehab El Shehawy; Julien Gigault; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; suspended solids; microplastics; bacteria; biofilm; aggregation; ecotoxicology; microalgae; Environmental Sciences; miljövetenskap;

    Sammanfattning : Increasing concerns arise regarding the environmental risk of microplastics (MP) and their interactions with biota, prompting numerous effect studies. However, current ecotoxicology methods fall short when it comes to assessing MP impacts. LÄS MER

  4. 13. 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 :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

  5. 14. Factors regulating the origin and magnitude of carbon dioxide emissions from high-latitude lakes

    Författare :Hendricus Verheijen; Jan Karlsson; Cristian Gudasz; David A. Seekell; Marcus Klaus; Anne Ojala; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; lake; carbon dioxide; organic carbon; inorganic carbon; arctic; emission; environmental science; miljövetenskap; climate change; klimatförändringar; Physical Geography; naturgeografi;

    Sammanfattning : Lake ecosystems receive, transmit and process terrestrial carbon and thereby link terrestrial, aquatic and global carbon cycles. Most lakes evade CO2 to the atmosphere, but the annual magnitude of CO2 evasion, as well as sources and mechanisms underpinning CO2 evasion from lakes are still largely unresolved. LÄS MER

  7. 15. Degradation Pathways of Dimethylmercury in Natural Waters

    Författare :Johannes West; Sofi Jonsson; Andrew Graham; Elena Gorokhova; Bridget Bergquist; Stockholms universitet; []
    Nyckelord :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
