Scrubber systems spray water into a ship's exhaust gases to remove sulfur from the emissions.

The wastewater from this process is released into the sea in an open-loop system or recirculated into the system via a closed-loop.

However, most of the wastewater is eventually dumped into sea or sometimes onto land.

Researchers found that the PAH mostly did not originate from combustion but from the fuel used, and there were alkylated PAH derivatives.
