POPs paleoenvironmental record over the last 220 years from an ice core retrieved at the plateau site of Dome C, Antarctica
Persistent organic pollutants (POPs) are ubiquitous in the environment and are affected by long-range atmospheric transport (LRAT) due to their low vapour pressure. Therefore, these substances have been found in almost every environmental matrix worldwide, including the remote regions of Arctic and...
