Research project Objectives of this project are to identify factors which influence the formation of halogenated natural products (HNPs) in Nordic coastal ecosystems and predict how their levels and transport pathways might be affected by climate change.
Halogenated natural products (HNPs) are secondary metabolites containing chlorine, bromine and/or iodine. They are produced by marine bacteria, phytoplankton, macroalgae and some invertebrate animals. HNPs have many ecological functions which include chemical communication, antimicrobial and antifouling activity, and protection from herbivory and predation. They are also of concern from an environmental perspective. Halomethanes diffuse to the stratosphere where they participate in ozone destruction. Some of the higher molecular mass HNPs bioaccumulate and have toxic properties similar to those of anthropogenic chemicals.
Climate change is expected to have an impact on HNPs by shifting the environmental distribution of producing species and formation of these secondary metabolites, which will have consequences for ecosystem functioning and environmental quality. We are investigating sources and pathways of HNPs in Nordic coastal ecosystems with the overall goal to predict climate change impacts on production and transport.
