Ex-situ process for treating PAH-contaminated soil with Phanerochaete chrysosporium
Article Abstract:
A fungal reactor system with separate soil extraction and fungal incubation units can effectively treat soils contaminated with polycyclic aromatic hydrocarbons (PAHs). The system, which uses a known lignin degrader, the white rot fungus Phanerochaete chrysosporium, successfully combines mechanical washing with biological degradation. The P. chrysosporium in the system has substantially reduced the total PAH concentration in a highly contaminated soil sample, which was spiked with [7,-10-14C]benzo[a]pyrene, by 45% through polymerization processes.

Spatial and temporal variation of polycyclic aromatic hydrocarbons in the Arctic atmosphere
Article Abstract:
The three-year air sampling program conducted at three locations in the Canadian and Russian Arctic that commenced in 1992 showed spatial and temporal variations on concentrations of polycyclic aromatic hydrocarbons (PAHs) in the Arctic atmosphere. The highest concentrations of PAHs were detected during colder months of October to April, indicating a clear seasonality. PAHs seemed to have traveled far from Eurasia into the high Arctic as evidenced by the air mass back trajectories computed for February 1994.

Characterization of wood combustion particles: morphology, mobility, and photoelectric activity
Article Abstract:
Studies reveal that the wood combustion particles appear like compact structures with fractal-like dimensions close to three and contained low mass fractions of volatile compounds such as particle-bound polycyclic aromatic hydrocarbons (PPAHs). It was also found out that the amount of combustion air supply influence particle size distribution of wood combustion particles and the emission of PPAHs.
