(Peer reviewed; Journal article, 2020)Gjennom drikkevannsforskriften er vannverkene pålagt å ha tilstrekkelige hygieniske barrierer for å sikre helsemessig trygt drikkevann til enhver tid ute hos abonnentene. Adekvate overvåkningssystemer er nødvendige for å ... -
Effects of artificial ultraviolet B radiation on the macrophyte Lemna minor: a conceptual study for toxicity pathway characterization
(Peer reviewed; Journal article, 2020)Macrophytes inhabit waterways around the world and are used in hydroponics or aquaponics for different purposes such as feed and wastewater treatment and are thus exposed to elevated levels of UVB from natural and artificial ... -
Wastewater-based estimation of the prevalence of gout in Australia
(Peer reviewed; Journal article, 2020)Allopurinol, a first-line gout treatment drug in Australia, was assessed as a wastewater-based epidemiology biomarker of gout via quantification of the urinary metabolite, oxypurinol in wastewater. The in-sewer stability ... -

Concentration and distribution of naphthenic acids in the produced water from offshore Norwegian North Sea oilfields
(Peer reviewed; Journal article, 2020)Naphthenic acids (NAs) constitute one of the toxic components of the produced water (PW) from offshore oil platforms discharged into the marine environment. We employed liquid chromatography (LC) coupled to high-resolution ... -
No environmental effect on vaccine-induced reduced growth in Atlantic salmon Salmo salar smolts
(Peer reviewed; Journal article, 2020)Oil-adjuvanted vaccines reduce long-term growth in farmed Atlantic salmon Salmo salar, possibly via an increase in metabolic rate due to the energetic demands of the immune system. We tested this hypothesis by comparing ... -
Comparing DADA2 and OTU clustering approaches in studying the bacterial communities of atopic dermatitis
