From: The impact of scrubber discharge on the water quality in estuaries and ports
Increase in metal and PAH surface water concentrations (%) in the harbour docks (a) and the Scheldt estuary (b) caused by open loop scrubber discharge compared to current concentrations (grey, 100%) calculated with the scenario LOW (white) and scenario HIGH (black). The ratio between water quality standards (WQS) and current (grey) metal and PAH surface water concentrations in the docks (c) and the Scheldt estuary. The calculated concentration increase caused by open-loop scrubber discharge calculated by the scenario LOW (white) and scenario HIGH (black)
