1. 6. Packed Column Supercritical Fluid Chromatography : Applications in Environmental Chemistry

   Författare :Nicole Riddell; Bert van Bavel; Robert McCrindle; Ingrid Ericson Jogsten; Jake Ryan; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supercritical Fluid Chromatography; Mass Spectrometry; Ionization; POPs; APPI; APCI; chiral; achiral; packed column;

   Sammanfattning : Although gas and liquid chromatography have emerged as dominant separation techniques in environmental analytical chemistry, these methods do not allow for the concurrent analysis of chemically diverse groups of persistent organic pollutants (POPs). There are also a small number of compounds which are not easily amenable to either of these traditional separation techniques. LÄS MER

   Sammanfattning : Chemicals offer a wide range of desired functions and are used in a variety of consumer goods and industrial sectors. The number of individual synthetic organic chemicals produced and the total global chemical production volume are increasing. LÄS MER

5. 9. Chlorinated Paraffins: improved understanding of their bioaccumulation and toxicity in Daphnia magna

   Författare :Mafalda Castro; Magnus Breitholtz; Anna Sobek; Elena Gorokhova; Lillemor Asplund; Martin Scheringer; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chlorinated paraffins; POPs; bioaccumulation; toxicity; ecotoxicology; aquatic toxicology; daphnia magna; liposomes; passive dosing; hydrophobic; mixtures; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Chlorinated paraffins (CPs) are industrial chemicals, mainly used as flame retardants, plasticizers and metal cutting fluids. Their production has reached historically high levels in the last decade, with an annual production exceeding one million tonnes. LÄS MER

7. 10. Exposure and body burden of environmental pollution and risk of cancer in a historically contaminated areas

   Författare :Ingela Helmfrid; Gun Wingren; Helen Karlsson; Marika Berglund; Mats Fredrikson; Mattias Öberg; Linköpings universitet; []
   Nyckelord :Contaminated area; cancer; exposure; metals; POPs; Consumption of local food;

   Sammanfattning : There are many villages where environmental contamination is substantial due to historical industrial activities. According to the European Environment Agency, there are about 2.5 million potentially contaminated sites in the European member states. In Sweden, there are about 80 000 more or less contaminated areas. LÄS MER
