    Author : Prajwol Prajapati; [2022]
    Keywords : Hydrodynamic modelling; water quality; PFAS; PFOS; PFHxS; MIKE 3 FM; Ekoln; Fyrisån;

    Abstract : Per and polyfluoroalkyl substances (PFAS) are found ubiquitously in the environment across the globe.These substances have high persistence due to the strong carbon and fluorine bond. In the aquaticenvironment, due to high persistence, these substances don’t decay easily and are detected on the surfaceas well as in groundwater sources. READ MORE

    Keywords : plastic; micro plastic; POPs; pollutants; additives; effects; animals; plast; miljögifter; tillsatser; effekter; djur;

    Abstract : Small pieces of plastic, termed “micro plastic” in the oceans derive mainly from degradation of big plastics such as beach littering, but also from sources of direct emission from e.g. beauty scrubbers and synthetic sand-blasting. These micro plastics are ingested by marine animals – mistaking them for plankton – or via prey. READ MORE
