What sources there could be? I remember that in the 1980s the indigineous Sami-population was whining about "pollution" of Porsanger fjord. Fish had diseases and crabs were dead. Upon investigation it was found out that cruiseships dump their toilets into the sea upon entering Honningsvåg, because the docking & dumping fees were too stiff. Nothing wrong with fishing nowadays.
