Occurrence of Perfluoroalkyl Compounds in Surface Waters from the North Pacific to the Arctic Ocean
Chinese Arctic and Antarctic Administration; National Natural Science Foundation of China [40776003] Perfluoroalkyl compounds (PFCs) were determined in 22 surface water samples (39-76 degrees N) and three sea ice core and snow samples (77-87 degrees N) collected from North Pacific to the Arctic Ocea...
