My main research interests are uptake and effects of pharmaceuticals in aquatic environments. My research focus lies with ionizable chemicals; a group to which the majority of all pharmaceuticals belong. Ionizable pharmaceuticals will have different degrees of uncharged/ionic speciation depending on the surrounding pH and thereby also change their degree of organism partitioning. Uncharged molecules can more easily enter across biomembranes then ions, which could result in higher uptake and increased toxicity.

So, why are pH-dependent differences in uptake and toxicity important to study? Well, aquatic environments show both temporal and spatial differences in pH, which potentially affect uptake and toxicity within and between water masses. Differences in pH could for instance result in higher toxicity during an organism’s more sensitive life stages, which potentially could change population density and ultimately even affect the whole community.

I will test the effect different water pHs have on partitioning, toxicity and bioaccumulation in aquatic organisms such as zooplankton and fish e.g. crucian carp (Carassius carassius). Selected pharmaceuticals to study are NSAIDs, such as ibuprofen, naproxen, diclofenac and ketoprofen and SSRIs, such as fluoxetine and sertraline.
