Rapport till Naturvårdsverket för projektet "Analys av polybromerade difenyletrar (PBDE) och hexabromcyklododekan (HBCDD) i human mjölk från Stockholm – en tidstrends studie [Dnr 721-2653-05Mm]
Swedish Environmental Protection Agency 2005 (Swedish)Report (Other academic)
The objective of the present study was to assess the temporal trends of polybrominated diphenyl ethers (PBDEs), including decaBDE, and hexabromocyclododecane (HBCDD) in mothers milk from the Stockholm area. The pooled samples were covering the time period 1980 to 2004, with emphasis on samples from the last ten years. The temporal trend of PBDEs must be expressed on a congener basis since the development of the individual PBDE congener concentrations differ. BDE-47, -99 and -100 concentrations reached a peak in the mid 1990’s and are now clearly showing decreasing levels. BDE-153 concentrations increased until year 2000 and thereafter the concentrations may level off but it is yet not clear how the concentrations of this PBDE congener will develop over the next few years. It is not possible to quantify decaBDE (BDE-209) in the human milk. This may be due to poor transfer to the milk lipids but most likely it is a result of the short half-life of this compound in human blood. HBCDD concentrations are 2004, approximately four times the concentration in 1980 showing an increasing temporal trend until the early 2000’s. It is too early to judge if the levels are decreasing or leveling off. The HBCDD concentrations are in a range between BDE-47 and BDE-99 and BDE-100.
