| Abstract |
The North Sea is being under loaded in many ways, both by organic and anorganic pollutants. Transport over rivers is the most evident way. Direct emission along the coastline and dumping of toxic materials by vessels are another two causes of pollution. Exploitation of oil and gas platforms also lead to operational emission of certain noxious substances. “Last but not least” a part of the pollutants also reach the North Sea through the atmosphere.This article specifically concerns the latter facet of North Sea Pollution. Both gaseous and particular material is being emitted in the atmosphere through incineration and other polluting processes. After physical dispersion and chemical transformation, these pollutants can end up in the sea through deposit processes. Heavy metals are usually found in the particular phase. In dry weather conditions these particles are removed from the atmosphere through gravitation, turbulent diffusion and impaction; this is referred to as dry deposit. In wet weather conditions particles can get caught in raindrops or snowflakes and this way end up in sea: wet deposit. |
