Biodegradation of naphthalene from coal tar and heptamethylnonane in mixed batch systems
Article Abstract:
Microorganisms can deplete a significant amount of naphthalene. This was the result of the first demonstration of substantial microbial degradation and depletion of naphthalene from coal tar. Experiments with nonaqueous phase liquid (NAPL)-water batch systems were conducted to evaluate the rates and extents of microbial degradation of naphthalene from coal tar and from a two-component NAPL with a simpler composition than coal tar. Naphthalene's degradation rate was found to be substantially influenced by the rate of external surface mass transfer from the coal tar.

Chemical characterization of coal tar-water interfacial films
Article Abstract:
A study was conducted on coal tar-water interfacial films. Gas chromatography, nuclear magnetic resonance and Fourier transform infrared techniques were used to analyze and compare the coal tar film and the bulk coal tar. No significant differences were detected in the organic composition of the two samples, although a primary difference was that only the film material held water.

Mass transfer and bioavailability of PAH compounds in coal tar NAPL-slurry systems. 2. experimental evaluations
Article Abstract:
Independent equilibrium and kinetic dissolution appear to aid in measuring the bioavailability of polynuclear aromatic hydrocarbons (PAH) and potential initial biotransformation rates. Mass transfer results are useful tools to determine the physicochemical and biokinetic limitations on non-aqueous-phase liquids (NAPLs)
