Large emissions from ship scrubbers

The Baltic Sea is considered one of the world’s most polluted seas. Now, new research reveals a relatively unknown environmental culprit. The study shows that the discharge water from ships’ exhaust gas treatment systems, so-called scrubbers, is responsible for up to nine percent of certain emissions of carcinogenic and environmentally harmful substances in the Baltic Sea, which is considerably more than was previously known. Furthermore, the number of ships equipped with scrubbers have tripled since the study was carried out.
