Technically all oceans are in some way or another polluted; the ocean is one gigantic mass of salt water, and the currents will move harmful chemicals around in it, just as they will with nutrients.

Also since almost every landmass in the world is occupied by humans, and the majority of our species pollut in some manner of another. It is very difficult to not have the majority of oceans be polluted in some way.
