摘要
Environmental pollutants,such as persistent organic pollutants(POPs),enter the Arctic mainly via long-range transport(LRT)through atmospheric and ocean/river currents.On the other hand,chemicals of emerging Arctic concern(CEACs)are often introduced as local contaminants from industrial,municipal,or infrastructure-related releases.Regardless of their origins,all these contaminants negatively impact the health of the environment and the indigenous populations.Furthermore,in recent decades,the Arctic has been experiencing unprecedented climate changes.The combination of Arctic environmental changes and the introduction of new anthropogenic contaminants as chemical aids for exploiting Arctic resources led to a severe imbalance in the Arctic ecosystems.Therefore,an international consortium of Arctic experts asked for internationally coordinated actions to mitigate the serious problems that environmental pollution causes on Arctic ecosystems and people,according to the Berlin statement[1].
