21. Models of the Distribution of Persistent Organic Pollutants in the Marine Environment
Sammanfattning : Persistent organic pollutants (POPs) is a group of chemicals that are toxic, undergo long-range transport and accumulate in biota. Due to their persistency the distribution and recirculation in the environment often continues for a long period of time. LÄS MER
22. Persistent halogenated pollutants in mothers´ milk
Sammanfattning : Persistent organic pollutants (POPs) are substances that degrade slowly, are distributed wotldwide, bioaccumulate and are harmful to both animals and humans. The release of POPs to the environment was the preamble to human background contamination. LÄS MER
23. Persistent organic pollutants in benthic foodwebs
Sammanfattning : Concentrations of persistent organic pollutants (POPs) in aquatic biota are dependent on several factors both on individual and on system level. Bioaccumulation of POPs in pelagic biota in lakes as well as fish in streams has been shown to be dependent on nutrient regime of the system. LÄS MER
24. Persistent organic pollutants in Swedish first-time mothers and effects on infant health
Sammanfattning : Humans are exposed to a variety of persistent organic pollutants (POPs) that have been spread to the environment because of various human activities. Food is the main source of exposure to most POPs. Many POPs are lipid-soluble, accumulate in the human body and are easily transferred to the fetus and to breastfed infants through breast milk.

25. Extraction of PCBs from Sediments: Towards Bioavailability Assessment Based on Supercritical Fluid Extraction
Sammanfattning : Persistent organic pollutants (POPs) pose serious threats to our global environment. These compounds have high chemical and biological stability and they are also very lipophilic. LÄS MER
