Analysis, occurrence and removal efficiencies of organophosphate flame retardants (OPFRs) in sludge undergoing anaerobic digestion followed by diverse thermal treatments
Varela, Gabriela Castro; Sørmo, Erlend; Yu, Guanhua; Sait, Shannen Thora Lea; Villa Gonzalez, Susana; Arp, Hans Peter Heinrich; Asimakopoulos, Alexandros (Peer reviewed; Journal article, 2023)Organophosphate flame retardants (OPFRs) are a complex group of contaminants to deal with in sewage sludge, as currently there is a lack of robust analytical methods to measure them and management strategies to remove them. ... -
Avoiding the Next Silent Spring: Our Chemical Past, Present, and Future
Arp, Hans Peter Heinrich; Aurich, Dagny; Schymanski, Emma L.; Sims, Kerry; Hale, Sarah Elizabeth (Peer reviewed; Journal article, 2023)Rachel Carson’s Silent Spring, (1) published just more than 60 years ago, outlined how the indiscriminate use of dichlorodiphenyltrichloroethane (DDT), a potent, environmentally persistent insecticide, was damaging the ... -
The decomposition and emission factors of a wide range of PFAS in diverse, contaminated organic waste fractions undergoing dry pyrolysis
Sørmo, Erlend; Varela, Gabriela Castro; Hubert, Michel; Licul-Kucera, Viktória; Quintanilla, Marjorie; Asimakopoulos, Alexandros; Cornelissen, Gerard; Arp, Hans Peter Heinrich (Peer reviewed; Journal article, 2023)Current treatment options for organic waste contaminated with per- and polyfluoroalkyl substances (PFAS) are generally limited to incineration, composting or landfilling, all resulting in emissions. Dry pyrolysis is a ... -
Distribution of PAHs, PCBs, and PCDD/Fs in products from full-scale relevant pyrolysis of diverse contaminated organic waste
Sørmo, Erlend; Krahn, Katinka Muri; Flatabø, Gudny Øyre; Hartnik, Thomas; Arp, Hans Peter Heinrich; Cornelissen, Gerard (Peer reviewed; Journal article, 2023)Biomass pyrolysis is the anoxic thermal conversion of biomass into a carbon rich, porous solid, often called biochar. This could be a better waste management alternative for contaminated organic wastes than incineration, ... -
Electrochemical Oxidation for Treatment of PFAS in Contaminated Water and Fractionated Foam─A Pilot-Scale Study
Smith, Sanne J.; Lauria, Melanie; Ahrens, Lutz; McCleaf, Philip; Hollman, Patrik; Bjälkefur Seroka, Sofia; Hamers, Timo; Arp, Hans Peter Heinrich; Wiberg, Karin (Peer reviewed; Journal article, 2023)Per- and polyfluoroalkyl substances (PFAS) are persistent synthetic contaminants that are present globally in water and are exceptionally difficult to remove during conventional water treatment processes. Here, we demonstrate ... -
Exposure assessment of plastics, phthalate plasticizers and their transformation products in diverse bio-based fertilizers
Estoppey, Nicolas; Varela, Gabriela Castro; Slinde, Gøril Aasen; Hansen, Caroline Berge; Løseth, Mari Engvig; Krahn, Katinka Muri; Demmer, Viona; Svenni, Jørgen; Tran, Teresa-Van-Anh Thi; Asimakopoulos, Alexandros; Arp, Hans Peter Heinrich; Cornelissen, Gerard (Peer reviewed; Journal article, 2024)Bio-based fertilizers (BBFs) produced from organic waste have the potential to reduce societal dependence on limited and energy-intensive mineral fertilizers. BBFs, thereby, contribute to a circular economy for fertilizers. ... -
Influence of grain size, organic carbon and organic matter residue content on the sorption of per- and polyfluoroalkyl substances in aqueous film forming foam contaminated soils - Implications for remediation using soil washing
Hubert, Michel; Arp, Hans Peter Heinrich; Hansen, Mona Cecilie; Castro, Gabriela; Meyn, Thomas; Asimakopoulos, Alexandros; Hale, Sarah Elizabeth (Peer reviewed; Journal article, 2023)A soil that was historically contaminated with Aqueous Film Forming Foam (AFFF) was dry sieved into size fractions representative of those produced during soil washing. Batch sorption tests were then conducted to investigate ... -
Occurrence and sorption behaviour of bisphenols and benzophenone UV-filters in e-waste plastic and vehicle fluff
Runde, Kristin; Castro, Gabriela; Vike-Jonas, Kristine; Villa Gonzalez, Susana; Asimakopoulos, Alexandros; Arp, Hans Peter Heinrich (Peer reviewed; Journal article, 2022)Bisphenols and benzophenone UV-filters are hazardous, high production volume chemicals. There is concern that these contaminants could leach into the environment or be recycled into new products during waste management. ... -

Per- and polyfluoroalkyl substance (PFAS) removal from soil washing water by coagulation and flocculation
Hubert, Michel; Meyn, Thomas; Hansen, Mona Cecilie; Hale, Sarah Elizabeth; Arp, Hans Peter Heinrich (Peer reviewed; Journal article, 2024)Soil washing is currently attracting attention as a promising remediation strategy for land contaminated with per- and polyfluoroalkyl substances (PFAS). In the soil washing process, the contaminant is transferred from the ... -

Langberg, Håkon Austad; Arp, Hans Peter Heinrich; Varela, Gabriela Castro; Asimakopoulos, Alexandros; Knutsen, Heidi (Peer reviewed; Journal article, 2023)Per- and polyfluoroalkyl substances (PFAS) have been used in paper products since the 1960s. PFAS emissions during the life cycle of these products have been substantial sources of these substances to the environment. Here, ... -
Soil Metabolome Impacts the Formation of the Eco-corona and Adsorption Processes on Microplastic Surfaces
Yao, Shi; Li, Xiaona; Wang, Tao; Jiang, Xin; Song, Yang; Arp, Hans Peter Heinrich (Peer reviewed; Journal article, 2023)The eco-corona on microplastics refers to the initial layer of biomolecular compounds adsorbed onto the surface after environmental exposure. The formation and composition of the eco-corona in soils have attracted relatively ... -
