    Abstract : Brominated flame retardants (BFRs) are chemicals used in e.g. electronic equipment, textiles and plastics for the prevention of fire. Over recent decades, concern has been raised regarding some heavily used BFRs, since the levels in the environment have been increasing. READ MORE

  2. 2. Interaction of brominated flame retardants with the chicken and zebrafish androgen receptors

    Author : Solomon Asnake; Per-Erik Olsson; Dennis Larsson; Örebro universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; DBE-DBCH; TBP-AE; TBP-BAE; TBP-DBPE; gene transcription; Biology; Biologi;

    Abstract : The survival of organisms depends on their ability to use different signaling pathways to adapt to the environment. The endocrine system consists of glands that release hormones to the blood stream. Male reproductive functions are regulated by androgens through interactions with the androgen receptor (AR).

  3. 3. Exposure of zebrafish to brominated environmental chemicals : studies on reproduction, maternal transfer and early life-stage development

    Author : Anna Norman Haldén; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Abstract : Fish reproduction and embryonic development may be sensitive to environmental chemicals. This thesis investigated effects of brominated flame retardants (BFRs) and polybrominated dibenzo-p-dioxins (PBDDs) on reproduction and early life-stage development in zebrafish (Danio rerio).

  4. 4. Polybrominated dibenzo-p-dioxins : Natural formation mechanisms and biota retention, maternal transfer, and effects

    Author : Kristina Arnoldsson; Peter Haglund; Patrik Andersson; Walter Vetter; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; polybrominated dibenzo-p-dioxins; PBDDs; Baltic Sea; uptake; retention; maternal transfer; metabolism; bioavailability; natural formation; precursor; bromoperoxidase; bromophenol; photochemical transformation; oxidative coupling; hydroxylated polybrominated diphenyl ethers; Chemistry; Kemi; analytisk kemi; Analytical Chemistry;

    Abstract : Polybrominated dibenzo-p-dioxins (PBDD) and dibenzofurans (PBDF) are a group of compounds of emerging interest as potential environmental stressors. Their structures as well as toxic responses are similar to the highly characterized toxicants polychlorinated dibenzo-p-dioxins. READ MORE
