Combining Leaching and Passive Sampling to Measure the Mobility and Distribution between Porewater, DOC and Colloids of Native Oxy-PAHs, N-PACs and PAHs in Historically Contaminated Soil
Enell, Anja; Lundstedt, Staffan; Arp, Hans Petter Heinrich; Josefsson, Sarah; Cornelissen, Gerard; Wik, Ola; Kleja, D. Berggren (Journal article, 2016)Different methods to quantify soil porewater concentrations of contaminants will provide different types of information. Passive sampling measurements give freely dissolved porewater concentrations (Cpw,free), while leaching ... -
Limited mobility of dioxins near San Jacinto super fund site (waste pit) in the Houston Ship Channel, Texas due to strong sediment sorption
Louchouarn, Patrick; Seward, Shaya M.; Cornelissen, Gerard; Arp, Hans Petter Heinrich; Yeager, Kevin M.; Brinkmeyer, Robin; Santschi, Peter H. (Peer reviewed; Journal article, 2018)Sediments from a waste pit in Houston Ship Channel (HSC) were characterized using a number of molecular markers of natural organic matter fractions (e.g., pyrogenic carbon residues, PAHs, lignins), in addition to dioxins, ... -
PAH i forurenset sediment: Utredning av egnethet av PAHkomponenter/ grupperinger for vurdering av tiltaksbehov
Ruus, Anders; Arp, Hans Petter Heinrich; Oen, Amy M P; Grung, Merete; Breedveld, Gijs D. (Research report, 2015)I Norge er det utarbeidet klassegrenser for til sammen 16 PAH-forbindelser i sediment og vann. Grenseverdiene baserer seg på kunnskap om toksisitet av de ulike stoffene og hva som er akseptabel eksponering for miljøet. I ... -
Ranking REACH registered neutral, ionizable and ionic organic chemicals based on their aquatic persistency and mobility
Arp, Hans Petter Heinrich; Brown, T.N.; Berger, U.; Hale, Sarah (Peer reviewed; Journal article, 2017)The contaminants that have the greatest chances of appearing in drinking water are those that are mobile enough in the aquatic environment to enter drinking water sources and persistent enough to survive treatment processes. ... -
Reducing Uncertainty and Confronting Ignorance about the Possible Impacts of Weathering Plastic in the Marine Environment
Jahnke, Annika; Arp, Hans Petter Heinrich; Escher, Beate I.; Gewert, Berit; Gorokhova, Elena; Kühnel, Dana; Ogonowski, Martin; Potthof, Annegret; Rummel, Christophe Daniel; Schmitt-Jansen, Mechtild; Toorman, Erik; MacLeod, Matthew (Peer reviewed; Journal article, 2017)Plastic in the global oceans fulfills two of the three conditions for pollution to pose a planetary boundary threat because it is causing planetary-scale exposure that is not readily reversible. Plastic is a planetary ... -
Research on the relationship between urban form and urban smog in China
Liu, Yong; Arp, Hans Petter Heinrich; Song, Xiaodong; Song, Yu (Journal article, 2017)The present study aims at exploring whether aspects of urban form (compactness ratio and elongation ratio) are associated with urban smog (particulate matter) in China. Quantitative indicators relating to urban form and ... -
The mass flow and proposed management of bisphenol A in selected Norwegian waste streams
Arp, Hans Petter Heinrich; Morin, Nicolas; Hale, Sarah; Okkenhaug, Gudny; Breivik, Knut; Sparrevik, Magnus (Journal article; Peer reviewed, 2017)Current initiatives for waste-handling in a circular economy favor prevention and recycling over incineration or landfilling. However, the impact of such a transition on environmental emissions of contaminants like bisphenol ... -
Towards threshold-based management of freshwater ecosystems in the context of climate change
Liu, Junguo; Kattel, Giri R.; Arp, Hans Petter Heinrich; Yang, Hong (Journal article, 2015)Climate change is an increasing threat to freshwater ecosystem goods and services. We review recent research regarding the direct and indirect impacts of climate change on freshwater ecosystems and the severity of their ... -
Using REACH registration data to rank the environmental emission potential of persistent and mobile organic chemicals
Schulze, Stefanie; Sättler, Daniel; Neumann, Michael; Arp, Hans Petter Heinrich; Reemtsma, Thorsten; Berger, Urs (Journal article; Peer reviewed, 2018)Organic chemicals that are persistent and mobile in the aquatic environment exhibit a hazard to contaminate drinking water resources. In this study an emission score model was developed to rank the potential of substances ...
