It is known that a large proportion of ship-based particulate emissions enter the atmospheric and maritime environment unhindered. As part of the SAARUS joint project, the Leibniz Institute for Baltic Sea Research is investigating these particles for organic pollutants (e.g. PAHs), metal residues, elementary composition and ecotoxicological hazard potential. Using highly sensitive measuring instruments, an evaluation of the effects of the use of scrubbers following the entry into force of the IMO regulations on the reduction of SOx emissions will provide information on their environmentally relevant consequences. In cooperation with a washing water treatment company, the extent to which the scrubber washing water is contaminated with pollutants and an optimization of the washing water treatment can be carried out is being examined. The aim is to use the open-loop mode in compliance with the EU directives with the specified limit values for priority substances in surface waters (2008/105/EC, Dec. 2008).
