11. Catchment influences on mercury methylation in a peatland chronosequence
University essay from SLU/Dept. of Aquatic Sciences and AssessmentAbstract : Since the beginning of industrialization, emissions of mercury (Hg) from human activities in excess of natural levels have increased depo-sition rates to ecosystems, storage in soils and loading to aquatic envi-ronments. Toxicity to animals, subject to this accumulation, as well as to humans consuming them, are the major concerns driving research on this subject. READ MORE

13. Miljögifters påverkan på delfiners hälsa och överlevnad : individ och populationsnivå
University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public HealthAbstract : Delfiner är utsatta för många antropogena hot, där en av dessa är miljögifter. Bioackumulering och biomagnifiering uppstår ofta på grund av delfinernas höga position i näringskedjan och miljögifternas persistens, vilket resulterar i höga nivåer av föroreningar i späck. Detta kan i sin tur leda till olika toxiska effekter. READ MORE

14. Spreading of persistent organic pollutants from fiber bank sediments
University essay from SLU/Dept. of Aquatic Sciences and AssessmentAbstract : Discharge of untreated wastewater from paper and pulp industries have led to large environmental impacts on the coastal sediments in Västernorrland, Sweden. Dissolved fibers caused the formation of large fiber banks and fiber influenced sediment areas, which proved to be highly affected by contamination with persistent organic pollutants (POPs).

15. 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
