Mat á svörun lífvera gagnvart mengun

Mat á svörun lífvera gagnvart mengun með beitingu bíómarkera. Umtalsverðar rannsóknir fara fram í Háskólasetrinu á áhrifum mengandi efna á sjávarlífverur, svo sem þungmálma og PAH sambanda, sem koma úr olíu, auk þess sem rannsóknir fara fram á eiturefnum sem til mögulega koma til með að vera notuð sem virk efni í botnmálningu skipa í framtíðinni. Í rannsóknunum taka þátt þau Halldór P. Halldórsson, Jörundur Svavarsson, Åke Granmo og Anneli Hilvarsen.

Nú er á döfinni rannsóknaverkefni sem beinist að því að meta áhrif mengandi efna á vaxtarrými krækling. Verkefnið verður unnið af Erasmus-nemendunum Ergina Alberdi Zubizarreta og Mercè Prat Hernández,  í samvinnu við Halldór P. Halldórsson og Jörund Svavarsson.
