Technological Advances
Developments in pump design and technology Developments in pump design and technology made it possible to consider much stricter made it possible to consider much stricter controls on the amount of residues that can be controls on the amount of residues that can be discharged into the marine environment discharged into the marine environment (stripping limits)(stripping limits)
Advances in knowledge on marine pollution Advances in knowledge on marine pollution meant that it was becoming clear that meant that it was becoming clear that properties not previously considered in the properties not previously considered in the categorization of products should be given categorization of products should be given more weight while others were perhaps not so more weight while others were perhaps not so important as had been thoughtimportant as had been thought
