Economic activity in the Arctic seas is not the only source of pollution. The growing presence of military weapons systems in the region raises concerns of increased pollution.[citation needed] Management of specific risks of marine pollution in the Arctic is governed primarily by national legislation in coastal states, although these take existing international standards into account. Bilateral agreements exist between Arctic states on cooperation in the prevention of marine pollution in the Arctic seas and immediate responses in case of oil spills. Nevertheless, there is no legal framework relating to weapons and other military presence.
