The Gauss-peak spectra (GPS) method represents individual pigment as weighted sums of Gaussian functions, and uses these to model absorbance phytoplankton mixtures. We here present several improvements for this type methodology, including adaptation plate reader technology efficient fitting by open source software. use a one-step modeling both absorption background attenuation with non-negative least squares, following one-time instrument-specific calibration. fitted is shown be higher than...
Background Despite the growing awareness of necessity a sustainable development, global economy continues to depend largely on consumption non-renewable energy resources. One such resource is fossil oil extracted from seabed at offshore platforms. This type production causes continuous environmental pollution drilling waste, discharge large amounts produced water, and accidental spills. Methods principal findings Samples natural populations haddock (Melanogrammus aeglefinus) Atlantic cod...
Semipermeable membrane devices (SPMD) and polar organic chemical integrative samplers (POCIS) were exposed to a cocktail of chemicals using flow-through system. Samplers removed analyzed every 7 d over four-week period in order determine sampling rates (Rs) for individual compounds. Prior laboratory exposure, half the allowed foul naturally six weeks, examine differences uptake due fouling. The amount fouling ranged from 0.2 2.8 g dry weight/dm2 POCIS 0.1 1.4 SPMDs, pattern accumulation was...
The applicability of silicone rubber and low-density polyethylene (LDPE) as passive sampling materials for target nontarget analyses moderately polar nonpolar substances was assessed through a field deployment samplers along small, polluted stream in Oslo, Norway. Silicone LDPE identical surface area (but different volumes) were deployed at 6 sites the River Alna 49 d. Quantitative analysis by gas chromatography-mass spectrometry (quadrupole, single-ion monitoring mode) demonstrated that...
Abstract The Norwegian water column monitoring program investigates the biological effects of offshore oil and gas activities in waters. In three separate surveys 2006, 2008, 2009, bioaccumulation biomarker responses were measured mussels (Mytilus edulis) Atlantic cod (Gadus morhua) held cages at known distances from produced (PW) discharge Ekofisk field. Identical studies performed all years have allowed data to be compared, addition, enabled potential environmental benefits a PW treatment...
Per- and polyfluoroalkyl substances (PFAS) are ubiquitous contaminants which also found in drinking water. Concentration levels water vary widely range from a very low contribution to total daily exposure for humans being the major source of uptake PFAS. PFAS concentrations Norwegian has been rarely reported. We investigated 31 164 samples, representing both (i.e., before treatment) finished Samples were taken 18 different bodies across Norway. The 17 waterworks involved supply 41 %...
The uptake characteristics of semipermeable membrane devices (SPMDs) and polar organic chemical integrative samplers (POCISs) were examined for mono, di tributyltin, triphenyltin, pyrene, benzo[a]pyrene, 4-tert-butylphenol, 4-n-nonylphenol, PCBs 77 153, PBDE 47, lindane, triclosan DDT. Exposure in a flow through system continued 28 days with removed every 7 order to study the relevant kinetics. Uptake remained linear POCISs sampling rates (Rs) up 0.2 L d−1. For SPMDs varied from approaching...
Summary 1. How climate warming may interact with other pressures on aquatic ecosystems is an important issue for research and management. We combined lake monitoring data a palaeolimnological study to explore the effects of eutrophication subsequent oligotrophication long‐term temperature increase in epilimnetic waters. Our goals were (i) evaluate how well sediment‐based reconstructions reflect instrumental observations, (ii) use palaeo‐record characterise reference state (iii) whether from...
During the Norwegian Tangaroa balsa raft expedition crossing Pacific in 2006, surface water samples were collected by passive semipermeable membrane device (SPMD) sampling, active microlayer collection, and fish bile collection. The analyzed for contamination including a range of persistent organochlorine contaminants, pesticides, polycyclic aromatic hydrocarbons, as well modern widespread chemicals such brominated flame retardants, UV-filters, perfluorinated compounds, using network expert...
