Plastic pollution in the hyporheic zone: occurrence and its interaction with microorganisms
Plastic pollution is a global issue, yet our understanding of its impact on organisms and ecosystems remains limited. My PhD thesis explores the presence of microplastics (MP) in river ecosystems, their interaction with freshwater hyporheic biofilms and specifically, the response of hyporheic biofilms to polyethylene terephthalate (PET) pollution in the …
Removal of contaminants of emerging concern using algal photobioreactors
Contaminants of emerging concern (CEC) are organic pollutants occurring in wastewater and consequently enter the environment. An alternative to conventional wastewater treatment are algal photobioreactors, which treat wastewater with low energy input while producing nutrient- and energy-rich algal biomass and treated water, which both have the potential to be reused. …
Determination of steroid estrogens in environmental samples using chemical analysis (GC-MSD) and an in vitro estrogenicity assay (ER-Calux®)
The presence of steroid estrogens in the environment has been studied intensively for two decades because of their possible deleterious effects on living organisms at very low (ng/L) concentrations. To determine concentrations of steroid estrogens and the estrogenic potential of environmental samples, sophisticated and sensitive analytical techniques as well as …
Occurrence, fate and removal of pharmaceutical residues in water treatment
The presence of pharmaceutical residues in surface waters is an emerging environmental issue that provides a new challenge to treatment systems for potable water, wastewater and water reuse. Their principle pathways into the sewerage system are twofold: first, after being administered to patients they are normally excreted as various metabolites …
