Biodegradation of Polycyclic Aromatic Hydrocarbons (PAHs) in Petroleum Contaminated Soils
Polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern. PAHs are one of the most prevalent groups of contaminants found in soil. Biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie. In this research biotreatment of PAH (phenanthrene) was studied in a solid-phase reactor using indigenou...
متن کاملPartitioning of crude oil polycyclic aromatic hydrocarbons in aquatic systems.
This paper investigates the hypothesis that observed polycyclic aromatic hydrocarbon (PAH) concentrations in an aqueous system are equal to the sum of the organic phase and soluble phase molar concentrations. While the organic phase concentrations are proportional to the PAH mole fraction in the oil, the soluble phase molar concentrations are estimated using Raoult's law. A batch laboratory mix...
متن کاملTransport of Polycyclic Aromatic Hydrocarbons in a Calcareous Wetland Soil
Knowledge of transport and degradation of polycyclic aromatic hydrocarbons (PAHs) is important in assessing PAH contamination of soils and water resources. The transport of naphthalene, anthracene, pyrene and phenanthrene was determined in a contaminated calcareous soil obtained from the Shadegan wetland (Khozestan, Iran) considering a column study in laboratory conditions. The PAHs were added ...
متن کاملThe Identification of Aromatic Polycyclic
In previously reported experiments, the car cinogenic potency for mice of extracts of processed rubber was traced to the presence of 3,4-benz pyrene and related compounds (13). A search for the origin of these hydrocarbons was next under taken. Samples of crude rubber, both natural and synthetic, did not contain any of these hydrocar bons when they were sought by extraction, chro matography, an...
متن کاملPolycyclic aromatic hydrocarbon selected galaxies
Context. This is the fourth in a series of papers based on the ISOCAM Parallel Survey at 6.7 μm. While the first three papers have been devoted to active galactic nuclei (AGN), here we report on emission-line galaxies without AGN signatures in their optical spectra. Aims. Polycyclic aromatic hydrocarbon (PAH) emission has been found in both starbursts and modestly starforming galaxies, but the ...
