Comment:

Persistent Organic Pollutants (Pops) can be found almost everywhere on the planet, in all of our bodies and in much of our food. In addition, because they spontaneously migrate towards the colder regions of the planet, POPs pose a critical threat to northern indigenous people, whose survival, health and well being depend on their traditional relationship with the ecosystem and the food it provides. Some of the most highly exposed populations are indigenous people living in polar regions far from major POPs sources. For example, the Inuit living on Baffin Island carry seven times as many PCBs in their bodies as people living in lower latitudes.
