POPs are globally distributed via long-range transport in air and ocean currents. They are transported from both primary and secondary sources, e.g. urban areas, and may accumulate in the remote Arctic.
The Arctic has a vulnerable ecosystem, which is particularly sensitive to climate change and already exhibits clear impacts, such as increased snow and glacier melting. Climate change has the potential to remobilize POPs from snow and soil and alter the pathways by which these chemicals cycle through the environment and food webs.
Development of policies to reduce levels of environmental contamination and protect human health, require a -scientific basis, and climate changes need to be taken into account. The ArcRisk project provides a rich source of information that can be used to make comparisons with situations in other parts of Europe, now and under future scenarios of climate change.
The research within the ArcRisk project aimed to answer the question:
How does the climate change affect the fate of contaminants and their impact on health in the Arctic?
