Role of nanoporosity and hydrophobicity in sequestration and bioavailability: tests with model solids
Article Abstract:
The entrapment with nanopores and the hydrophobicity of organic compounds affect their sequestration and bioavailability. Silica beads with varying pore sizes sorbed 10-99% of phenanthrene in 15 h, but 48-100% of the sorbed hydrocarbon was desorbed in 24 h. Phenanthrene was extensively degraded despite its minimal desorption from octadecyl-bonded silica beads with 6-nm pores.

Combined effect of sequestration and bioremediation in reducing the bioavailability of polycyclic aromatic hydrocarbons in soil
Article Abstract:
A study found that amounts of fluoranthene, phenanthrene, anthracene, and pyrene in soil could be reduced by sequestration and bioremediation. The polycyclic aromatic hydrocarbons in the soil were aged 140-203 days and then subjected to degrading bacteria. The results were studied by investigating the amounts of the compounds assimilated by earthworms.

Effect of concentration on sequestration and bioavailability of two polycyclic aromatic hydrocarbons
Article Abstract:
Research was conducted to examine the effects of concentration on the bioavailability and sequestration of pyrene and phenanthrene in the soil. Data revealed that the sequestration of these hydrocarbons occurs at both high and low concentrations.
