Global warming and the increased human activity
in High North are changing the Arctic environment causing melting of the ice
cap and higher air temperatures.[1]
The changes in the Arctic environment put under threat the whole Arctic
ecosystem and rise serious environmental security concerns regarding the
maintenance of the local and the planetary biosphere.
PERSISTENT ORGANIC
POLLUTANTS
In recent decades the Arctic temperature has
raised as much as 3.5ºC during winter months. Various persistent organic
pollutants (POPs)[2] and
other contaminants[3] are
transported by air to Arctic were they are
deposited in the ice through precipitation or deposition.[4]
Contaminants are also carried to Arctic by
ocean and river discharges. According to the 1997/98 AMAP assessment of
pollution in Arctic , POPs were present in
parts of the region where there was no human activity to explain the
contamination. This piece of evidence confirmed that the northern polar
region served as a sink for pollutants that had been transported over long
distances.[5]
