The combined emissions of metals and other environmentally hazardous substances from ships is putting the marine environment at risk according to a new study from Chalmers University of Technology, Sweden. When the researchers calculated the contaminant load from these emissions into the marine environment in four ports, it was found that water discharged from ships' scrubbers, whose purpose is to clean their exhaust gases, accounts for more than 90% of the contaminants.

A research team at Chalmers University of Technology in Sweden claims to be the first to demonstrate that it is possible to reduce the aerodynamic resistance of ships by up to 7.5% by utilising what is known as the “Coanda effect”.
