Hydrocarbons in soil and meltwater stream sediments near Artigas Antarctic Research Station: origin, sources and levels
Abstract Aliphatic and polycyclic aromatic hydrocarbons (AHs and PAHs) were investigated in soil and meltwater stream sediments near the Uruguayan Artigas Research Station (BCAA). Gas chromatography with flame ionization detection and gas chromatography mass spectrometry were used to determine the c...
