  2. 21. Chlorinated Paraffins: improved understanding of their bioaccumulation and toxicity in Daphnia magna

    Author : Mafalda Castro; Magnus Breitholtz; Anna Sobek; Elena Gorokhova; Lillemor Asplund; Martin Scheringer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chlorinated paraffins; POPs; bioaccumulation; toxicity; ecotoxicology; aquatic toxicology; daphnia magna; liposomes; passive dosing; hydrophobic; mixtures; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Chlorinated paraffins (CPs) are industrial chemicals, mainly used as flame retardants, plasticizers and metal cutting fluids. Their production has reached historically high levels in the last decade, with an annual production exceeding one million tonnes. READ MORE

  4. 22. Exploring the ecotoxicity of microparticle debris

    Author : Zandra Gerdes; Elena Gorokhova; Martin Ogonowski; Tamara Galloway; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microplastics as emerging pollutants; hazard assessment; ecotoxicological experimental design; aquatic toxicology; chemical vector; suspended solids; reference particles; crustaceans as test organisms; behavioural assays in ecotoxicology; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The global distribution and anticipated increase of environmental microplastic (MP) pollution are concerning. However, while the impacts of macroplastic litter on wildlife are apparent, we know relatively little about the MP hazard potential. READ MORE

  5. 23. Impact of epidemiologically identified mixtures of endocrine disrupting chemicals on metabolic programming

    Author : Polina Lizunkova; Joëlle Rüegg; Elin Engdahl; Joachim Sturve; Carl-Gustaf Bornehag; Juliette Legler; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Endocrine disrupting chemicals; Mixtures; Metabolism; Developmental Toxicology; Epigenetics; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

    Abstract : We are ubiquitously exposed to a plethora of endocrine-disrupting chemicals (EDCs), i.e. substances that alter the function(s) of the endocrine system. While ample evidence show individual EDC's influence on developmental processes resulting in adverse health outcomes, less is known about the effects of human-relevant EDC mixtures exposure.

  6. 24. Microbiome Of Ecotoxicity Assays

    Author : Asa Motiei; Elena Gorokhova; Natàlia Corcoll; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biofilm; Microplastics; Suspended solids; Aquatic toxicology; Daphnia magna; Ecotoxicology; Bacterial colonization; Particle aggregation; Microbiome interaction; Standardization; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Microorganisms are ubiquitous and present in animal microbiomes, particulates, and colonizable surfaces of test systems. From an ecotoxicological perspective, they are metabolically active biological compartments that respond to test conditions, including test substances. READ MORE

  7. 25. Responses to reduced industrial metal emissions : An ecotoxicological study on Pied Flycatcher (Ficedula hypoleuca, Aves)

    Author : Åsa Berglund; Erik Nyholm; John Elliott; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Toxicology; Toxikologi; Other biology; Övrig biologi; ekotoxikologi; Ecotoxicology; zooekologi; Animal Ecology; environmental science; miljövetenskap;

    Abstract : Metals have been used by humans for thousands of years, and this has resulted in increased concentrations in the biosphere. The environment around point-sources, such as mines and smelters, are of particular concern, as metals may accumulate to high concentrations, and potentially reach levels toxic to the local flora and fauna.
