2. 6. Fate and exposure assessment of PCDD/Fs at contaminated sites

   Author : Annika Åberg; Karin Wiberg; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; contaminated sites; dioxins; PCDD F; exposure; food chain; modeling; risk assessment; physical-chemical properties; förorenade områden; dioxiner; PCDD F; exponering; födokedja; modellering; riskbedömning; fysikaliska-kemiska egenskaper; Environmental chemistry; Miljökemi;

   Abstract : Polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzo-furans (PCDFs) belong to the most toxic compounds known to science and they are defined as Persistent Organic Pollutants (POPs) under the Stock-holm Convention. The general human exposure to PCDD/Fs is primarily through dietary intake. READ MORE

4. 7. Predicting Ecosystem Response from Pollution in Baltic Archipelago areas using Mass-balance Modelling

   Author : Olof Magnus Karlsson; Andreas Bryhn; Lars Håkanson; Per Jonsson; Mikael Malmaeus; Kristoffer Naes; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; archipelagos; aquatic ecosystems mass-balance modelling; sediment-water dynamics; phosphorus; dioxins; PCDD Fs; Other earth sciences; Övrig geovetenskap; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

   Abstract : Baltic archipelago areas have high nature values despite being polluted from various antrophogenic activities within the Baltic Sea catchment area and from long-range transport of airborne substances. The discovery of environmental problems in the Baltic Sea in the 1960s led to countermeasures that gradually gave results in reducing the toxic pollution, e. READ MORE

5. 8. The relationship between fly ash chemistry and the thermal formation of polychlorinated pollutants during waste incineration

   Author : Duong Ngoc Chau Phan; Stellan Marklund; Bogdan Dlugogorski; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Incinerations; dioxins; PCDD Fs; PCBs; PCNs; flue gas; fly ash; sampling; particle characterization; XPS; XRD; SEM EDX; formation; chlorination; PCA; OPLS; OPLS-DA;

   Abstract : The thermal formation of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), biphenyls (PCBs), and naphthalenes (PCNs) is a major problem in waste incineration. Ideally, rather than relying on air cleaning systems and treatment techniques, their formation should be minimized or, if possible eliminated. READ MORE

6. 9. Dietary exposure to persistent organochlorine compounds and health effects in women and their infants - Epidemiological studies on birthweight, cancer incidence, and mortality

   Author : Lars Rylander; Avdelningen för arbets- och miljömedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; birthweight; breast cancer; ischemic heart disease; n-3 polyunsaturated fatty acids; CB-153; PCB; dibenzofurans; dioxins; fish consumption; persistent organochlorine compounds; gender ratio; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin;

   Abstract : In Sweden the main exposure route for both polychlorinated biphenyls (PCB) and other persistent organochlorine compounds is through consumption of fatty fish species from the Baltic Sea (the eastern coast of Sweden). Cohorts of fishermen's wives from the Swedish east and west coasts were established. READ MORE

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

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

   Abstract : 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.
