Differences in sediment organic matter composition and PAH weathering between non-vegetated and recently vegetated fuel oiled sediments

INTERNATIONAL JOURNAL OF PHYTOREMEDIATION, 10(6), 473–485.

By: S. Gregory n & E. Nichols n

author keywords: polycyclic aromatic hydrocarbon (PAH); C-14 accelerator mass spectrometry (AMS); Phragmites; cattails; willow trees
MeSH headings : Biodegradation, Environmental; Fuel Oils / analysis; Geologic Sediments / chemistry; Plant Roots; Poaceae / metabolism; Polycyclic Aromatic Hydrocarbons / chemistry; Salix / metabolism; Soil Pollutants / chemistry; Soil Pollutants / metabolism; Typhaceae / metabolism
TL;DR: Polycyclic aromatic hydrocarbon attenuation in contaminated field sediments after only 2 years of plant growth is examined to hypothesized that bulk sediment and humin fractions with measurable increases in plant organic matter content would show measurable changes to PAH attenuation as indicated by more weathered PAH diagnostic ratios or reduced PAH concentrations.

2008 journal article

The impact of vegetation on sedimentary organic matter composition and PAH desorption

ENVIRONMENTAL POLLUTION, 156(3), 928–935.

By: E. Nichols*, S. Gregory* & J. Musella*

author keywords: Phragmites; PAHs; Desorption; Sediments; Phytoremediation
MeSH headings : Adsorption; Biodegradation, Environmental; Chrysenes / analysis; Gas Chromatography-Mass Spectrometry; Geologic Sediments / analysis; Humic Substances / analysis; Plants / metabolism; Polycyclic Aromatic Hydrocarbons / analysis; Polycyclic Aromatic Hydrocarbons / pharmacokinetics; Polymers; Pyrenes / analysis; Soil / analysis; Soil Pollutants / pharmacokinetics
TL;DR: After several decades of plant colonization and growth (Phragmites australis), vegetated sediment fractions more extensively desorbed PAHs and had faster desorption kinetics than non-vegetation sediment fractions. (via Semantic Scholar)
