Environmental factors influencing mercury speciation in Subarctic and Boreal lakes
(Journal article; Peer reviewed, 2014)Environmental drivers of total mercury (TotHg) concentrations, methylmercury (MeHg) concentrations, and MeHg fractions (a proxy for methylation potential, expressed as %MeHg) were assessed in a synoptic study of 51 lakes ... -
Towards a comprehensive and realistic risk evaluation of engineered nanomaterials in the urban water cycle
(Journal article; Peer reviewed, 2014) -
Combined effects of pharmaceuticals, personal care products, biocides and organic contaminants on the growth of Skeletonema pseudocostatum
(Journal article; Peer reviewed, 2014)Organisms in the environment are exposed to a number of pollutants from different compound groups. Inaddition to the classic pollutants like the polychlorinated biphenyls, polyaromatic hydrocarbons (PAHs),alkylphenols, ... -
Secchi depth in the Oslofjord-Skagerrak area: theory, experiments and relationships to other quantities
(Journal article; Peer reviewed, 2014)The Secchi depth and its relationships to other properties of the sea water in the Oslofjord–Skagerrak area have been investigated. White and black disks of different sizes have been applied, and the Secchi depth has been ... -
Self-reports of consumption of amphetamines, cocaine and heroin in a survey among marginalized drug users
(Journal article, 2014)Scientific literature offers few measurements of the quantities consumed by individual drug users. Such measurements are used for calculating the total drug consumption by the quantity-frequency method, and are extremely ... -
Morphologically Conservative but Physiologically Diverse: The Mode of Stasis in Anostraca (Crustacea: Branchiopoda)
(Journal article; Peer reviewed, 2014)The essay discusses whether biotic and abiotic environments differ in their ability to speed up or slow down morphological change and the generation of new lineages. Examples from the class Branchiopoda show that morphological ... -
Stable isotope evidence for the bottom convective layer homogeneity in the Black Sea
(Journal article; Peer reviewed, 2014) -
Importance of wave and current exposure to fauna communities in Laminaria hyperborea kelp forest
(Journal article; Peer reviewed, 2014)Hydrodynamic forces from waves and currents may have strong but different impacts on benthic diversity. In order to study the relative importance of current and wave exposure to the diversity of macrofauna associated with ... -
Using biomarkers in wastewater to monitor community drug use: A conceptual approach for dealing with new psychoactive substances
(Journal article; Peer reviewed, 2014)Data obtained from the analysis of wastewater from large-scale sewage treatment plants has been successfully applied to study trends in the use of classical illicit drugs such as cocaine, but the dynamic nature of the new ... -
Effects of sample preparation on methylmercury concentrations in arctic organisms
(Journal article; Peer reviewed, 2014)The biogeochemical cycling of mercury (Hg) in the marine environment is an issue of global concern, as consumption of marine fish is a major route of human exposure to the toxic specie methylmercury (MeHg). The most widely ... -
Applying Adverse Outcome Pathways (AOPs) to support Integrated Approaches to Testing and Assessment (IATA)
(Journal article; Peer reviewed, 2014)Chemical regulation is challenged by the large number of chemicals requiring assessment for potential human health and environmental impacts. Current approaches are too resource intensive in terms of time, money and animal ... -
Global transcriptional analysis of short-term hepatic stress responses in Atlantic salmon (Salmo salar) exposed to depleted uranium
(Journal article; Peer reviewed, 2014)Potential environmental hazards of radionuclides are often studied at the individual level. Sufficient toxicogenomics data at the molecular/cellular level for understanding the effects and modes of toxic action (MoAs) of ... -
Immunohistochemical localization of inflammatory cells and cell cycle proteins in the gills og Loma salmonae infected rainbow trout (Oncorhynchus mykiss)
(Journal article; Peer reviewed, 2014)Microsporidial gill diseases particularly those caused by Loma salmonae incur significant economic losses to the salmonid aquaculture industry. The gill responses to infection include the formation of xenomas and the acute ... -
Effects of sample preservation and storage on mercury speciation in natural stream water
(Journal article; Peer reviewed, 2014)Despite an increasing focus on low level methods for determination of mercury species in water over the last decades, few studies have paid attention to direct effects of different sample preparation methods (i.e. preservation ... -
Filtration characterization method as tool to assess membrane bioreactor sludge filterability-the Delft experience
(Journal article; Peer reviewed, 2014)Prevention and removal of fouling is often the most energy intensive process in Membrane Bioreactors (MBRs), responsible for 40% to 50% of the total specific energy consumed in submerged MBRs. In the past decade, methods ... -
Use of High Throughput Sequencing and Light Microscopy Show Contrasting Results in a Study of Phytoplankton Occurrence in a Freshwater Environment
(Journal article; Peer reviewed, 2014)Assessing phytoplankton diversity is of primary importance for both basic and applied ecological studies. Following the advances in molecular methods, phytoplankton studies are switching from using classical microscopy to ... -
