  2. 1. Chemical reactivities as a mirror of environmental transformations - method development and assessment of some selected organohalogens

    Author : Lisa Granelli; Åke Bergman; Johan Eriksson; Roland Kallenborn; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi; miljökemi; Environmental Chemistry;

    Abstract : The assement of chemical persistence is an important part of legislative protection of the environment and human health. Of the vast number of chemicals on the market today few have been properly assessed. READ MORE

  4. 2. Occurrence and fate of emerging and legacy flame retardants : from indoor environments to remote areas

    Author : Seth Newton; Cynthia de Wit; Ulla Sellström; Matthew MacLeod; Roland Kallenborn; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Flame retardant; emerging; legacy; polybrominated diphenyl ethers; PBDE; HBCDD; long range transport; dust; air; soil; atmospheric deposition; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Persistent organic pollutants (POPs) are toxic chemicals that can be found in various matrices in all corners of the planet, including remote areas such as the Arctic.  Several POPs are known and monitored but given the abundance of new chemicals in commerce about which little is known, chemicals that may be new POPs are constantly being screened for.

  5. 3. Levels of organohalogen compounds in White-tailed sea eagles (Haliaeetus albicilla) in relation to reproduction impairment in the Bothnian Sea

    Author : Ulrika Nordlöf; Lillemor Asplund; Björn Helander; Yngve Zebuhr; Michael Mclachlan; Roland Kallenborn; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The white-tailed sea eagle (Haliaeetus albicilla) is in the top of the marine food chain and its existence in Sweden has been threatened several times. The species succeeded to recover from the deep decline in the 1970s when the exposure to persistent organic pollutants influenced the reproduction negatively. READ MORE

  6. 4. Bis(4-chlorophenyl) sulfone and PCB methyl sulfone metabolites : Trends and chirality in the Baltic Sea environment

    Author : Karin Norström; Åke Bergman; Mats Olsson; Roland Kallenborn; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bis 4-chlorophenyl sulfone; PCB methyl sulfone; Baltic Sea; Environmental chemistry; Miljökemi;

    Abstract : The Baltic Sea was earlier identified as a highly polluted brackish water body and still is. The high concentrations of polychlorinated biphenyls (PCBs), p,p’-DDT and related compounds led to severe effects on several species in the Baltic region. READ MORE

  7. 5. Bioavailability of organic contaminants in a changing climate

    Author : Matyas Ripszam; Peter Haglund; Roland Kallenborn; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; climate change; organic contaminants; sorption; dissolved organic carbon; bioavailability;

    Abstract : The effects of predicted future climate change was investigated with special emphasis on the association of organic contaminants with dissolved organic carbon (DOC) in the Baltic Sea.An automated method was developed for the measurements of DOC - water distribution constants at realistic DOC concentrations in brackish water.
