1. Investigating the temperature mediated effects of antidepressant pharmaceutical on foraging behavior and activity in aquatic invertebrates
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Contamination by pharmaceuticals in aquatic environments is an increasing problem globally. Wide range of pharmaceuticals of different treatments classes are commonly detected in water and the tissues of organisms and there is a growing concern about how these substances might affect the aquatic ecosystems.

2. Pharmaceutical drugs in aquatic ecosystems : Does exposure to oxazepam alter behavior of brown trout (Salmo trutta) and consequently affect the dominance hierarchy?
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : A greater consumption of pharmaceutical drugs entails an increased concentration of active benzodiazepines in aquatic ecosystems. Consequently, aquatic organisms are experiencing altered behavior that may affect dominance hierarchies since social status (among other variables) is associated with behavioral traits. READ MORE

3. Uptake of per- and polyfluoroalkyl substances by plants
University essay from SLU/Dept. of Aquatic Sciences and AssessmentAbstract : The extensive use of per- and polyfluoroalkyl substances (PFASs) as surfactants in, for example textiles,cookware and aqueous firefighting foams (AFFFs) during the last decades has resulted in widespread environmental contamination. Due to the persistent and bioaccumulative characteristics of PFASs, they are ubiquitously found in the environment, wildlife and humans. READ MORE

4. The bioavailability of perfluoroalkyl substances (PFASs) and polycyclic aromatic hydrocarbons (PAHs) in soil to Eisenia fetida and Cucurbita pepo
University essay from SLU/Dept. of Aquatic Sciences and AssessmentAbstract : Persistent organic pollutants (POPs) are organic chemicals of great concern because of their persistency, bioaccumulation and toxic effects both in the environment and to humans. Two groups of organic chemicals that are partly listed as POPs are perfluoroalkyl substances (PFASs) and polycyclic aromatic hydrocarbons (PAHs). READ MORE

5. Ecotoxicological effects on a food-web exposed to pharmaceuticals : Uptake and effects of oxazepam, fexofenadine and a mixture of both in algae, zooplankton and sticklebacks.
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Complex mixtures of biologically active pharmaceutical residues continuously enter aquatic environments via wastewater, where it can affect species through preserved human drug targets or cause unexpected effects in non-target species. Benzodiazepines and antihistamines are two highly consumed groups of pharmaceuticals that have been shown to bioconcentrate in aquatic organisms and induce behavioural alterations affecting individual fitness.
