Investigating societal attitudes towards marine ecosystem restoration
(Peer reviewed; Journal article, 2020)Globally, direct and indirect human impacts have led to the widespread degradation of marine ecosystems. The resulting loss of habitat and marine biodiversity has led to the increased impetus for marine ecosystem restoration ... -
Investigation of ecotoxicological effects of wastewater from a magnesium industry (Norsk Hydro A/S, Porsgrunn, Norway)
(NIVA-rapport;1873, Research report, 1986)An ecotoxical evaluation of wastewater from Norsk Hydro A/S magnesium industry was carried out in connection with the establishment of a similar plant in Canada. The toxic effect of wastewater was low after pH adjustment ... -
Investigation of new brominated and organophosphorous flame retardants in Svalbard benthic marine food web; FlammePlank
(NIVA-rapport;7261, Research report, 2018)The aim of this pilot-study was to use silicone rubber-based passive samplers to measure novel brominated flame retardants (nBFRs), polybrominated diphenyl ethers (PBDEs) and dechlorane plus (DP) in seawater and air around ... -
Investigation of the effect of microplastics on the UV inactivation of antibiotic-resistant bacteria in water
(Peer reviewed; Journal article, 2022)This study investigated the effect of polyethylene and polyvinyl chloride microplastics on the UV fluence response curve for the inactivation of multidrug-resistant E. coli and enterococci in ultrapure water at pH 6.0 ± ... -
Investigations of mercury during a survey near submarine U-864 outside Fedje in 2013
(NIVA-rapport;6499, Research report, 2013)During a survey in January 2013 sediment samples were taken from the area near the wreck of submarine U-864 outside Fedje. The submarine is assumed to have had 67 tons of liquid mercury onboard, stored in carbon steel cans. ... -
