  1. 16. Microplastics in the marine environment and the assessment of potential adverse effects of associated chemicals

    Författare :Christine Schönlau; Anna Kärrman; Magnus Engwall; Magnus Breitholtz; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microplastics; reporter gene bioassays; sorption; HOCs; polyethylene; polypropylene; polystyrene;

    Sammanfattning : During the last decade plastics have gained interest by scientists as emerging pollutants particularly in the marine environment due to their ubiquity and persistence. While several studies report the occurrence of microplastics in surface waters globally, there are no harmonized methods to sample and measure microplastics, and the knowledge of toxicological effects in the marine ecosystem is scarce.

  3. 17. Physico-chemical characteristics and quantitative structure-activity relationships of PCBs

    Författare :Patrik Andersson; Stephen Safe; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polychlorinated biphenyls; PCBs; physico-chemical properties; statistical design; multivariate; PCA; PLS; biomagnification; BMF; bioassay; CYP1A; SAR; QSAR; REPs; risk assessment; Chemistry; Kemi; Chemistry; Kemi;

    Sammanfattning : The polychlorinated biphenyls (PCBs) comprise a group of 209 congeners varying in the number of chlorine atoms and substitution patterns. These compounds tend to be biomagnified in foodwebs and have been shown to induce an array of effects in exposed organisms. LÄS MER

  4. 18. Genetic, environmental and life-style effects on androgen receptor function

    Författare :Christel Björk; Malmö Molekylärgenetisk reproduktionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproductive function; smoking; 4 .4-DDE; persistent organic pollutants; prostate cancer; Androgen receptor; prostate specific antigen; CAG polymorphism; TCDD; aryl hydrocarbon receptor; CB-153;

    Sammanfattning : Androgens regulate male reproductive function and their effects are mediated through the androgen receptor (AR). The AR gene contains a polymorphic CAG repeat, encoding a stretch of glutamines, affecting the transcriptional activity of the AR. LÄS MER

  5. 19. Transcriptomics and bioconcentration studies in fish to identify pharmaceuticals of environmental concern

    Författare :Filip Cuklev Stern; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fish; microarray; bioconcentration; pharmaceuticals; wastewater treatment; environment;

    Sammanfattning : Pharmaceuticals are frequently found in the aquatic environment. As they are most often highly biologically active, quite persistent and may accumulate in aquatic organisms, i.e. bioconcentrate, they may pose a risk to non-target organisms. LÄS MER

  7. 20. Change of toxicity during secondary treatment of industrial sludge containing nitroaromatics

    Författare :Lillemor Gustavsson; Magnus Engwall; Anna Schnürer; Ulrika Welander; Mårten Jönsson; Bo Mattiasson; Göran Dave; Örebro universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic; aerobic; AhR agonists; CALUX; constructed wetlands; Danio rerio; embryotoxicity; genotoxicity; nitroaromatics; sludge; Environmental engineering; Miljöteknik; Enviromental Science; Miljövetenskap;

    Sammanfattning : Wastewater treatment plants in Sweden are facing a great challenge due to the prohibition of depositing organic waste which gained legal force in January 2005. Biological and commercial available alternatives to disposal are composting and anaerobic digestion. LÄS MER
