Effects of Leachates from UV-Weathered Microplastic in Cell-Based Bioassays
Rummel, Christophe Daniel; Escher, Beate I.; Sandblom, Oskar; Plassmann, Merle; Arp, Hans Peter; MacLeod, Matthew; Jahnke, Annika (Peer reviewed; Journal article, 2019)Standard ecotoxicological testing of microplastic does not provide insight into the influence that environmental weathering by, e.g., UV light has on related effects. In this study, we leached chemicals from plastic into ... -
Facilitating microplastic quantification through the introduction of a cellulose dissolution step prior to oxidation: Proof-of-concept and demonstration using diverse samples from the Inner Oslofjord, Norway
Olsen, Linn Merethe Brekke; Knutsen, Heidi; Mahat, Sabnam; Wade, Emma Jane; Arp, Hans Peter (Peer reviewed; Journal article, 2020)Identifying and quantifying microplastic in marine samples can be facilitated by removing natural organic matter (NOM). Cellulosic material, like chitin, however, are a type of NOM that is resistant to chemical digestion, ... -
Leachate emissions of short- and long-chain perand polyfluoralkyl substances (PFASs) from various Norwegian landfills
Knutsen, Heidi; Mæhlum, Trond; Haarstad, Ketil; Slinde, Gøril Aasen; Arp, Hans Peter (Peer reviewed; Journal article, 2019)Restrictions on the use of long-chain per- and polyfluoralkyl substances (PFASs) has led to substitutions with short-chain PFASs. This study investigated the presence of four short-chain PFASs and twenty-four long-chain ... -
Microplastic accumulation by tube-dwelling, suspension feeding polychaetes from the sediment surface: A case study from the Norwegian Continental Shelf
Knutsen, Heidi; Cyvin, Jakob Bonnevie; Totland, Christian; Wade, Emma Jane; Castro, Veronica; Pettersen, Arne; Laugesen, Jens; Møskeland, Thomas; Arp, Hans Peter; Lilleeng, Øyvind (Peer reviewed; Journal article, 2020)Sediment samples (0–1 cm) and tube-dwelling polychaetes from the Norwegian Continental Shelf and the Barents Sea were collected, including areas close to oil and gas installations and remote locations. Microplastics (≥45 μm) ... -
The presence, emission and partitioning behavior of polychlorinated biphenyls in waste, leachate and aerosols from Norwegian waste-handling facilities
Arp, Hans Peter; Morin, Nicolas; Andersson, Patrik L.; Hale, Sarah; Wania, Frank; Breivik, Knut; Breedveld, Gijs D. (Peer reviewed; Journal article, 2020)Even though production and open use of polychlorinated biphenyls (PCBs) have been phased out in Western industrialised countries since the 1980s, PCBs were still present in waste collected from different waste handling ...
