Historic records of organic compounds from a high Alpine glacier : influences of biomass burning, anthropogenic emissions, and dust Transport
Historic records of dicarbonyls (glyoxal,methylglyoxal), carboxylic acids (C6–C12 dicarboxylic acids, pinic acid, p-hydroxybenzoic acid, phthalic acid, 4- methylphthalic acid), and ions (oxalate, formate, calcium)were determined with annual resolution in an ice core from Grenzgletscher in the southe...
