Historic records of organic compounds from a high Alpine glacier: influences of biomass burning, anthropogenic emissions, and dust transport
Historic records of α -dicarbonyls (glyoxal, methylglyoxal), carboxylic acids (C 6 –C 12 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 th...
