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

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

    Abstract : 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. READ MORE

  4. 7. Coxsackievirus B3 Infection and Host Defence Responses Change the Metabolism of PBDE

    Author : Magnus Lundgren; Nils-Gunnar Ilbäck; Hans Tjälve; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coxsackievirus; environmental pollutants; PBDE; cytokines; chemokines; metabolism; infection; tissue distribution; toxicology; virology; immunology; Toxicology; Toxikologi; Virology; Virologi; Medicine; medicin;

    Abstract : It has been suggested that the rising amounts of chemicals in the environment may affect host resistance and increase susceptibility to infections. Studies have also shown that infections can change the toxicity of pollutants. READ MORE

  5. 8. Development of in silico methods to aid chemical risk assessment : focusing on kinetic interactions in mixtures

    Author : Elena Golosovskaia; Patrik L. Andersson; Stefan Örn; Patrik Rydén; Ester Papa; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; QSAR; physiologically based kinetic; PBK; zebrafish; ADME; mixture; bisphenols; PFAS; toxicokinetics; environmental science; miljövetenskap; Toxicology; toxikologi;

    Abstract : The environment and biota are constantly exposed to numerous chemicals through contaminated food, soil, water, and air. These chemicals can be taken up and distributed to reach sensitive tissues where they may cause various effects. Many of these chemicals lack data on their environmental and human health effects.

  6. 9. Generation, stability and migration of montmorillonite colloids in aqueous systems

    Author : Sandra García García; Mats Jonsson; Tiziana Missana; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bentonite; montmorillonite; colloid stability; colloid migration; geological disposal; nuclear waste; granitic fractures; ; Environmental chemistry; Miljökemi; Environmental toxicology; Miljötoxikologi; Surface and colloid chemistry; Yt- och kolloidkemi; Nuclear chemistry; Kärnkemi;

    Abstract : In Sweden the encapsulated nuclear waste will be surrounded by compacted bentonite in the granitic host rock. In contact with water-bearing fractures the bentonite barrier may release montmorillonite colloids that may be further transported in groundwater. READ MORE

  7. 10. Improving alternatives assessment of plastic additives : exploring in silico tools to identify less hazardous flame retardants

    Author : Ziye Zheng; Patrik L. Andersson; Hans Peter Arp; Gregory Peters; Gerrit Schüürmann; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemical alternatives assessment; plastic additives; flame retardants; hazard; emission; in silico; modeling; quantitative structure-activity relationship QSAR ; multi-criteria decision analysis MCDA ; environmental science; miljövetenskap; organisk kemi; Organic Chemistry; ekotoxikologi; Ecotoxicology; Toxicology; toxikologi;

    Abstract : Alternatives assessment is applied for replacing hazardous chemicals with viable, safer substitutes. High quality experimental hazard data, however, are usually unavailable for this purpose, and obtaining in silico data is the only approach to fill in data gaps. READ MORE
