Can polyethylene passive samplers predict polychlorinated biphenyls (PCBs) uptake by earthworms and turnips in a biochar amended soil?
Silvani, Ludovica; Hjartardottir, Sigurbjørg; Bielská, Lucie; Škulcová, Lucia; Cornelissen, Gerard; Nizzetto, Luca; Hale, Sarah (Peer reviewed; Journal article, 2019)A pot experiment was carried out in which aged polychlorinated biphenyls (PCBs) contaminated soil was amended with biochar, and three phases; earthworms, turnips and polyethylene (PE) passive samplers, were added simultaneously ... -
Fading positive effect of biochar on crop yield and soil acidity during five growth seasons in an Indonesian Ultisol
Cornelissen, Gerard; Jubaedah, X; Nurida, Neneng; Hale, Sarah; Martinsen, Vegard; Silvani, Ludovica; Mulder, Jan (Peer reviewed; Journal article, 2018)Low fertility limits crop production on acidic soils dominating much of the humid tropics. Biochar may be used as a soil enhancer, but little consensus exists on its effect on crop yield. Here we use a controlled, replicated ... -
Formation and availability of methylmercury in mercury-contaminated sediment: effects of activated carbon and biochar amendments
Sørmo, Erlend; Silvani, Ludovica; Braaten, Hans Fredrik Veiteberg; Bryntesen, Tina; Eek, Espen; Cornelissen, Gerard (Peer reviewed; Journal article, 2022)Purpose As the formation of toxic and bioaccumulative methylmercury (MeHg) in Hg-contaminated sediments is of great concern worldwide, suitable remediation options are needed. Activated carbon (AC) amendment is a contested ... -
Industrial byproducts for the soil stabilization of trace elements and per- and polyfluorinated alkyl substances (PFASs)
Zhang, Yaxin; Cornelissen, Gerard; Silvani, Ludovica; Zivanovic, Valentina; Smebye, Andreas; Sørmo, Erlend; Thune, Gorm; Okkenhaug, Gudny (Peer reviewed; Journal article, 2022) -
Monitoring alkylphenols in water using the polar organic chemical integrative sampler (POCIS): Determining sampling rates via the extraction of PES membranes and Oasis beads
Silvani, Ludovica; Riccardi, Carmela; Eek, Espen; Papini, Marco Petrangeli; Morin, Nicolas; Cornelissen, Gerard; Oen, Amy M P; Hale, Sarah (Peer reviewed; Journal article, 2017)Polar organic chemical integrative samplers (POCIS) have previously been used to monitor alkylphenol (AP) contamination in water and produced water. However, only the sorbent receiving phase of the POCIS (Oasis beads) is ... -
Sorption of α-, β-, γ- and δ-hexachlorocyclohexane isomers to three widely different biochars: Sorption mechanisms and application
Silvani, Ludovica; Cornelissen, Gerard; Hale, Sarah (Journal article; Peer reviewed, 2018)Within this study different biochars (BC) with widely varying characteristics have been tested as materials for the adsorption of hexachlorocyclohexane's (HCH) isomers (α, β, γ and δ) from water. Three BCs produced from ... -
Stabilization of PFAS-contaminated soil with activated biochar
Sørmo, Erlend; Silvani, Ludovica; Bjerkli, Nora; Hagemann, Nikolas; Zimmermann, Andrew R.; Hale, Sarah; Hansen, Caroline Berge; Hartnik, Thomas; Cornelissen, Gerard (Peer reviewed; Journal article, 2020)Biochars are considered potential sustainable sorbents to reduce the leaching of per- and polyfluoroalkyl substances (PFAS) fromcontaminated soils. However, biochar characteristicsmust probably be optimized to achieve ... -
The effect of biochar, lime and ash on maize yield in a long-term field trial in a Ultisol in the humid tropics
Hale, Sarah; Nurida, Neneng L.; Jubaedah, *; Mulder, Jan; Sørmo, Erlend; Silvani, Ludovica; Abiven, Samuel; Joseph, Stephen; Taherymoosavi, Sarasadat; Cornelissen, Gerard (Peer reviewed; Journal article, 2020)A multi-season field trial was carried out to investigate the effect of the amendment of biochar, lime, ash and washed biochar on the growth of maize. A degraded, strongly acidic Ultisol (pHKCl 3.60), with a relatively ... -
Waste timber pyrolysis in a medium-scale unit: Emission budgets and biochar quality
Sørmo, Erlend; Silvani, Ludovica; Thune, Gorm; Gerber, Helmut; Schmidt, Hans-Peter; Cornelissen, Gerard (Peer reviewed; Journal article, 2020)Pyrolysis of organic waste or woody materials yields a stable carbonaceous product that can be mixed into soil and is often termed “biochar”. During pyrolysis carbon-containing gases are emitted, mainly volatile organic ...
