ORGANIC COMPONENTS OF ANTARCTIC SNOW AND ICE : PART 1. VOLATILE FATTY ACIDS IN SNOW DRIFT
Snow drift samples collected on Mizuho Plateau, Antarctica, were analyzed for volatile fatty acids including formic, acetic, propionic and butyric acids. Formic (2.3-11.7 ppb) and acetic (11.4-59.8 ppb) acids were detected as major components. Their concentrations were far lower than those reported...
