The substances are transported to the Arctic in the atmosphere by ocean currents, and also by rivers and ice in the Arctic. These are the most important means of transport, but pollutants carried by animals which move between the polar areas may also have some significance.
How do ocean currents pollute remote locations?
Because ocean currents flow slowly, it may take decades for contaminants from heavily industrialised and populated places to reach the ocean. The ocean currents carry pollutants that are soluble in water and are dumped directly into the ocean or fall as rain into the ocean. The degree to which the contaminants are soluble in water will determine whether they bind to particles or sink to the seafloor. Such places might develop into what is known as sinks, or repositories for pollutants.
The layers in the water and the current systems govern the maritime transit of contaminants to the Arctic. It might take years for toxins to travel through the ocean and reach the Arctic. Then, they may stay under the water for a few years to several millennia.
Some radioactive compounds may be carried by ocean currents over great distances depending on how they behave in the marine environment.
Measures taken to stop pollutants from reaching the environment are delayed by the slow movement of the ocean currents towards the pole.
