Ecotoxicological testing of performance fluids
(NIVA-rapport;2414, Research report, 1990)Two performance fluids were tested for toxic effects on marine algae and biological degradability. A fluid based on mineral oil was readily degradable (98% DOC removal in 28 days) while a either based oil degraded more ... -
The ecotoxicology of marine tributyltin (TBT) hotspots: A review
(Peer reviewed; Journal article, 2022)Tributyltin (TBT) was widely used as a highly efficient biocide in antifouling paints for ship and boat hulls. Eventually, TBT containing paints became globally banned when TBT was found to cause widespread contamination ... -

(NIVA-rapport;2353, Research report, 1990)Planen beskriver EDB-virksomheten i dag og definerer mål og strategi for EDB-tjenester framover. Opplæring, teknologisk kursendring og avklaring av ansvarsforhold er fokusert spesielt. Tiltakene som foreslås er forankret ... -
Effect of clear-cutting of forest on the chemistry of a shallow groundwater aquifer in southern Norway
(NIVA-rapport;4226, Research report, 2000)Clear-cutting of forests have pronounced effects on chemistry of soils and runoff water. The major effects are increased water yield, changes in nutrient cycles and increased leakage of the nutrients nitrate and potassium ... -
Effect of Extreme Weather Events on Contaminant Transport From Urban Run-Off to a Fjord System
(Peer reviewed; Journal article, 2021)Urbanization has resulted in increased contaminant run-off in densely populated areas. Climate change is expected to result in a higher frequency of extreme weather events including torrential rainfall and storms. The ... -
The effect of fertilizer subsidies on investment in soil and water conservation and productivity among ghanaian farmers using mechanized irrigation
(Peer reviewed; Journal article, 2021)The fertilizer subsidies reintroduced in various sub-Saharan African countries from 2007 aim to increase agricultural production and assist in the development of fertilizer markets. The present study evaluates the impact ... -
The effect of long-range transport, trophic position and diet specialization on legacy contaminant occurrence in great skuas, Stercorarius skua, breeding across the Northeast Atlantic
(Peer reviewed; Journal article, 2019)High levels of halogenated organic contaminants (HOCs) have been found in the marine predatory seabird great skua (Stercorarius skua) from breeding colonies in the Northeastern Atlantic, with large unexplained inter-colony ... -
Effect of ocean acidification on growth and otolith condition of juvenile scup, Stenotomus chrysops
(Journal article; Peer reviewed, 2015)Increasing amounts of atmospheric carbon dioxide (CO2) from human industrial activities are causing changes in global ocean carbonate chemistry, resulting in a reduction in pH, a process termed “ocean acidification.” It ... -
Effect of oxidation with coagulation and ceramic microfiltration pre-treatment on reverse osmosis for desalination of recycled wastewater
(Journal article; Peer reviewed, 2018)Oxidation and coagulation before ceramic microfiltration (CMF) greatly increases membrane flux, but is unconventional for reverse osmosis (RO) pre-treatment. Impacts to RO and the wastewater recycling scheme operating CMF ... -
Effect of pooled sampling in the MILFERSK program
(NIVA-rapport;7925-2024, Research report, 2024)The MILFERSK monitoring program is studying the occurrence and biomagnification of contaminants in freshwater ecosystems, mainly Lake Mjøsa. For the last 10 years, individual samples of muscle and liver from brown trout ... -
Effect of ultrasonic cavitation on small and large organisms for water disinfection during fish transport
(Journal article; Peer reviewed, 2018)Motivated by the need for additional tools to disinfect discharge water from well boats, and to prevent distribution of salmon lice, the effect of ultrasonic cavitation on the planktonic stages of the salmon louse, nauplii ... -
