Impact assessment of ship scrubber effluents reveals adverse effects at realistic environmental concentrations—combining a systematic review of whole effluent ecotoxicological studies with dilution modelling Open
Concerns regarding the potential adverse effects of ship-generated scrubber effluent discharged to the marine environment and the growing number of ecotoxicological experiments have motivated a systematic review of the available whole effl…

Applying quantitative structure-activity relationship (QSAR) models to extend the mixture toxicity prediction of scrubber water Open
Marine organisms are constantly exposed to complex chemical mixtures from natural and anthropogenic sources. One source that has raised concerns is the discharge water from ships equipped with exhaust gas cleaning systems, commonly known a…

Projected changes of the emission and transport of organic pollutants and metals from shipping in European seas 2018–2050 Open
The ChemicalDrift model is applied to predict concentrations of metals and polycyclic aromatic hydrocarbons emitted from shipping in European seas in 2050, compared to 2018. Sources include antifouling paints (AFPs), discharge water from s…

Strong economic incentives of ship scrubbers promoting pollution Open
In response to stricter regulations on ship air emissions, many shipowners have installed exhaust gas cleaning systems, known as scrubbers, allowing for use of cheap residual heavy fuel oil. Scrubbers produce large volumes of acidic and po…

Central Arctic Ocean surface–atmosphere exchange of CO <sub>2</sub> and CH <sub>4</sub> constrained by direct measurements Open
The central Arctic Ocean (CAO) plays an important role in the global carbon cycle, but the current and future exchange of the climate-forcing trace gases methane (CH4) and carbon dioxide (CO2) between the CAO and the atmosphere is highly u…

Characterization of scrubber water discharges from ships using comprehensive suspect screening strategies based on GC-APCI-HRMS Open
An extended suspect screening approach for the comprehensive chemical characterization of scrubber discharge waters from exhaust gas cleaning systems (EGCSs), used to reduce atmospheric shipping emissions of sulphur oxides, was developed. …

Central Arctic Ocean surface-atmosphere exchange of CO <sub>2</sub> and CH <sub>4</sub> constrained by direct measurements Open
The Central Arctic Ocean’s (CAO) current and future role in the exchange of climate-forcing trace gases with the atmosphere is highly uncertain, in particular the effect of sea ice on the exchange. There are no previously reported direct a…

Central Arctic Ocean methane emission and carbon dioxide uptake constrained using floating chamber flux and gas transfer velocity measurements Open
<p>The Central Arctic Ocean&#8217;s (CAO) current and future role in the exchange of climate-forcing trace gases with the atmosphere is highly uncertain due to sparse observations of dissolved gas concentrations and sea-air fluxe…

Metal and PAH loads from ships and boats, relative other sources, in the Baltic Sea Open
The Baltic Sea is a sensitive environment that is affected by chemical pollution derived from multiple natural and anthropogenic sources. The overall aim of this study was to estimate the load of metals and polycyclic aromatic hydrocarbons…

Comparing emissions of polyaromatic hydrocarbons and metals from marine fuels and scrubbers Open
In January 2020, new global regulations were implemented to limit the maximum sulphur content in marine fuels. As an alternative to switch to compliant fuels, the regulations allow for installations of exhaust gas cleaning systems, e.g. sc…
