  1. 1. Polybrominated dibenzo-p-dioxins and furans : from source of emission to human exposure

    Författare :Filip Bjurlid; Jessika Hagberg; Bert van Bavel; Ingrid Ericson Jogsten; Peter Haglund; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PBDD Fs; PCDD Fs; marine mammal; combustion; fire; human milk; occupational exposure;

    Sammanfattning : Brominated flame retardants (BFRs), which are ubiquitous in modern life and the environment, are the major source for polybrominated dibenzo-p-dioxins and furans (PBDD/Fs). The knowledge about PBDD/Fs is lim-ited compared to other environmental pollutants, even though PBDD/Fs show similar toxicity as polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs) which are considered to be among the most toxic man-made substances.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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;

    Sammanfattning : 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. LÄS MER

  4. 3. PLE with integrated clean up followed by alternative detection steps for cost-effective analysis of dixons and dioxin-like compounds

    Författare :Erik Spinnel; Peter Haglund; Patrik Andersson; Tuulia Hyötyläinen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pressurized liquid extraction PLE ; PLE-C; modular PLE; ELISA; dioxin; dioxin-like compounds; GCxGC; analytical methods; Environmental chemistry; Miljökemi;

    Sammanfattning : Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are two structurally related groups of chemicals, generally referred to as `dioxins´. These are of great concern due to their high toxicity and global spread. LÄS MER
