Monitoring of Persistent Organic Pollutants (POPs): Examples from Lake Vättern, Sweden
Lake Vättern in southern Sweden is a large oligotrophic lake with high surface to catchment area ratio (ca. 0.4) and a water residence time of 60 years. The lake combines sensitivity to atmospheric POP-pollution with general susceptibility for effects of POPs and slow concentration decline. Time ser...
