  1. 16. Method Improvement for the Determination and Quantification of PCBs in the Muscle Tissues of Arctic Char (Salvelinus salvelinus) and European Whitefish (Coregonus acronius) from Lake Vättern, Sweden

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Melli Sejfic; [2015]
    Keywords : PCBs; Arctic char; European whitefish; Lake Vättern; sample pretreatment; silica;

    Abstract : Lake Vättern has been contaminated with high levels of polychlorinated biphenyls (PCBs) for decades, which could be due to the release of wastes from industries and urban communities surrounding the water system. This has especially had a negative effect on fatty fishes, which could accumulate large amounts of persistent organic pollutants (POPs) and thereby also become a source of environmental toxicants to humans through consumption.

  2. 17. Micro plastics in the oceans and their effect on the marine fauna

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    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

    Keywords : ;

    Abstract : Persistent organic pollutants (POPs) are ubiquitous contaminants characterized by semi-volatility, low water solubility, high lipophilicity and inherent toxicity. A combination of these properties results in long-rang transport, bioaccumulation and biomagnification through food webs. READ MORE
