Interactive processes between eutrophication and pollutant dynamics in the aquatic environment.
Experimental work is still in progress.
In polluted environments there is a simultaneous import of hydrophobic chemicals and metals with affinity for particulate organic material. Such potential environmental toxins are accumulating in sediments where high concentrations can be found. The turnover of sedimentary organic matter is a complicated web of biological and geo-chemical processes involving a huge number of interacting organisms. Our purpose with this project is to measure effects of potential environmental toxins on the rates by which solutes are produced or consumed in marine sediments. The rate of change of concentration in the porewater of sediments will thus serve as markers for all the subprocesses that are involved.
