Effects of plant flavonoids on the fate of polynuclear aromatic hydrocarbons in rhizosphere soil
… polynuclear aromatic hydrocarbons (PAHs) are persistent in the environment although a wide variety of microorganisms can metabolize PAHs. In the past decades, laboratory and filed studies have shown that PAH degradation in soil is often limited by poor bioavailability and oxygen …

Beneficial Reuse of Dredged Materials in Upland Environments
… of salts and polycyclic aromatic hydrocarbons (PAHs) were investigated. In the first part of this study, 176,000 m3 of saline dredged materials was placed into a CUF. In less than 4 years, most of the dredged materials had developed horizonation and converted to Inceptisols. The formation of …

Photochemical Reaction Products of Polycyclic Aromatic Hydrocarbons Adsorbed at an Air-Water Interface
Polycyclic aromatic hydrocarbons (PAH) are ubiquitous pollutants resulting from incomplete combustion and hence normally unavoidable. The kinetic aspects of the environmental degradation process have received considerable attention; however, not much is known about the degradation products …

Use of solvents for PAHs extraction and enhancement of the PAHs bioremediation in coal-tar-contaminated soils
… of the polycyclic aromatic hydrocarbons (PAHs) and their high partitioning with soils. As such, not all the PAHs present in the soil will be available for biodegradation. Enhancing the availability of PAHs will make bioremediation attractive as a treatment technology. Because of the PAH …

Ultrasonically Enhanced Mass Transport and Degradation of Polycyclic Aromatic Hydrocarbons in Solid-Liquid Two Phase Partitioning Systems
… with polycyclic aromatic hydrocarbons (PAHs) is endorsed by environmental protection agencies worldwide. Recent studies demonstrated the removal of these contaminants from soil utilizing polymer beads, with subsequent PAH release and degradation in solid-liquid two phase partitioning …

Characterization and comparison of microbial communities from different tourist ports in Mediterranean Sea and evaluation of applicability of bioremediation treatments
… of the effect of bioaugmentation treatments on PAH degradation in sediments at laboratory scale. Three tourist ports located across the Mediterranean Sea were selected as case study sites representative tourist harbours in the Basin: Cagliari (Sardinia, Italy) in the western part, El Kantaoui …
