Journal ArticleDOI
Fatty acid composition of 12 microalgae for possible use in aquaculture feed
Vishwanath Patil,Torsten Källqvist,Elisabeth Olsen,Elisabeth Olsen,Gjermund Vogt,Hans Ragnar Gislerød +5 more
TL;DR: This is the first report on the fatty acid profiles of Nannochloropsis oceanica, ChroococcusSp.
Journal ArticleDOI
Environmental assessment of Norwegian priority pharmaceuticals based on the EMEA guideline
TL;DR: Measured environmental concentrations confirmed that the release of ciprofloxacin from wastewater treatment works may potentially be of environmental concern in Norway.
Journal ArticleDOI
Assessment of ammonia toxicity in tests with the microalga, Nephroselmis pyriformis, Chlorophyta.
Torsten Källqvist,A. Svenson +1 more
TL;DR: Ammonia was found to be the dominant toxicant in the industrial effluent, using N. pyriformis as test organism and this alga appears to be more sensitive to ammonia than other studied marine plankton algae.
Journal ArticleDOI
Methods for growth inhibition toxicity tests with freshwater algae
Niels Nyholm,Torsten Källqvist +1 more
TL;DR: A critical review of batch-culture freshwater algal toxicity test methods (algal growth inhibition tests) is presented, revealing that the results from such tests can vary a great deal, in some cases by more than three orders of magnitude.
Journal ArticleDOI
Development of sediment quality criteria in Norway
TL;DR: A Norwegian system for classification of environmental quality of contaminated marine sediments has been in force since 1997 and was revised in 2007 as mentioned in this paper, which covers 43 compounds against 28 in the 1997 version.
