   Sammanfattning : Stable isotope analysis (SIA) is a valuable tool in ecotoxicology because δ13C and δ15N may provide insights into the trophic transfer of contaminants in a food web. The relationship between a species’ trophic position (TP, determined from δ15N) and internal concentration of biomagnifying contaminants can be established and used for regulatory purposes. LÄS MER

3. 2. Polyelectrolyte complexes : their preparation, adsorption behaviour and effect on paper properties

   Författare :Caroline Ankerfors; Lars Wågberg; Monica Ek; Tom Lindström; KTH; []
