Colloid characterization and colloidal phase partitioning of polycyclic aromatic hydrocarbons in two creosote-contaminated aquifers in Denmark
Article Abstract:
Polycyclic aromatic hydrocarbons (PAH), as found in creosote contaminate sites that previously were gas works, asphalt factories and wood preservation factories in Denmark. Researchers characterized the colloid population of groundwater in two such locations. Researchers also gathered data related to the in situ distribution of dissolved and colloidal phases of PAHs. Researchers sought to document the geology of the locations. Much of the resulting data appears in chart form. One chart documents levels of 15 elements found in the groundwater, including oxygen, iron, and silicon. A second chart documents levels of PAHs.

Analysis of hydrocarbon-contaminated soil by thermal extraction-gas chromatography
Article Abstract:
Thermal desorption was combined with gas chromatography (ThermEx-GC) in analyzing hydrocarbons in creosote- and petroleum-contaminated soil. A mixture of anthracene and phenanthrene loaded into clean soil was used to determine the detectability and reproducibility of the analysis. ThermEx-GC provides direct and rapid analysis of contaminated soils by volatilizing target compounds from the soil into the carrier gas of a gas chromatograph. However, ThermEx-GC must be calibrated to allow for nonlinear response to sample size and concentration of hydrocarbons on the soil.

Desorption of [14C]Naphthalene from bioremediated and nonbioremediated soils contaminated with creosote compounds
Article Abstract:
Results from the bioremediation of creosote-contaminated soil reveal that the partition coefficients of [14C]naphthalene, which are related to the mass of organic carbon in the soil, are unaltered even as the average molecular weight of the residual creosote is increased by 10% to 36%. The partition coefficients for the creosote contaminant yield about 3500 to 4040 mL/g of organic carbon from both bioremediated and nonbioremediated soil samples when partitioning is used to model the total contributions of the nonaqueous phase contaminant and the soil organic matter.
