Introduction Persistent Organic Pollutants (POPs) are chemical substances that persist in the environment for long periods after their release and accumulate heavily in the food change, particularly in fatty tissues, ultimately reaching concentrations that have harmful impacts on human health and the environment. In addition to this, POPs can potentially be transported over great distances and dispersed around the globe by air and ocean currents. They therefore pose a risk to the environment and human health not only locally and regionally, but also in parts of the world at a great distance from the point of emission. Arctic and mountainous regions, to which POPs are carried by air currents and where they are deposited as a result of condensation, appear to be at particular risk.
