Characterization of polycyclic aromatic hydrocarbon particulate and gaseous emissions from polystyrene combustion
Article Abstract:
The incineration of polystyrene spheres at increasing combustion temperatures and decreasing polystyrene feed size causes a reduction in the the total mass and number of polycyclic aromatic hydrocarbons (PAHs) released during combustion. The increase in incineration temperature and decrease in feed size, however, cause an increase in the mean diameter of the particles. Results also reveal that the PAH species in the particulate phase accumulated in the smaller aerosol sizes.

Surfactant-enhanced mobilization and biodegradation of polycyclic aromatic hydrocarbons in manufactured gas plant soil
Article Abstract:
Arkopal N-300 and Sapogenat T-300, two nonionic surfactants of the alkylphenolethoxylate type, appear to aid in the mobilization and biodegradation of manufactured gas plant soil contaminated with polycyclic aromatic hydrocarbons (PAHs). The surfactants increased the mass transfer rate and facilitated the solubilization of PAHs. The biodegradation of the surfactants is important to determine their usefulness in bioremediation efforts.

Survival of polycyclic aromatic hydrocarbons during diesel combustion
Article Abstract:
A radiotracer technique was used to detect residuals of polycyclic aromatic hydrocarbons (PAH) in emissions from the combustion of five 14C-radiolabeled PAH. A linear relationship was observed between the survival of individual PAH and the energy levels for each molecule. This suggests that the survival of PAHs are determined by their chemical kinetics instead of thermodynamic stabilities.
