Soil Stable Carbon Isoptope Analysis of Landscape Features at Aguateca, Guatemala
… properties, and the bulk soil organic matter and humin fractions were analyzed on a mass spectrometer to determine δ13C values. Graphs of the isotopic values were examined and the bulk and humin δ13C enrichment values for the landscape feature categories were compared statistically using ANOVA …

The Contribution of Different Carbonaceous Material Fractions to the Sorption of Hydrophobic Organic Contaminants to Subsurface Sediments
… matters dominate total carbon mass, with kerogen/humin the next most abundant CMs. Isotherm results indicate that condensed form CMs, most likely kerogen and humin, control the sorption of TCE. Even though the KCM values for particulate carbonaceous materials (PCM) are higher than those of the …
