DETERMINATION OF POLYCYCLIC AROMATIC HYDROCARBONS IN THE ICE CORE SAMPLES FROM GREENLAND
Polycyclic aromatic hydrocarbons (PAHs) were determined in the ice core samples taken from Greenland, Site-J (205 m long, ca. 450 years old) using a combined gas chromatography and mass spectrometry (GC-MS). More than forty PAHs ranging from naphthalene to benzo (ghi) perylene were detected in the i...
