Polycyclic aromatic hydrocarbons (PAHs) are classified as persistent and carcinogenic organic pollutants. PAHs contamination has been reported in water. Many of relevant regulatory bodies such as EU and EPA have regulated the limit levels for PAHs in drinking water. In this study, 13 priority polycyclic aromatic hydrocarbons (PAHs) were determined in tap water samples of Tehran and water for in...

Sixteen USEPA priority polycyclic aromatic hydrocarbons (PAHs) extracted by Soxhlet extraction (S-PAHs) with dichloromethane and routine accelerated solvent extraction (A-PAHs) with 1:1 toluene/methanol, respectively, were investigated in 24 soil samples from two cities in the center of the Pearl River Delta, South China. Polycyclic aromatic hydrocarbons, methylphenanthrene and perylene, in two...

For the first time, in May 2007, the distributions of polycyclic aromatic hydrocarbons (PAHs) were studied in the soft tissues (STs) (mantle, gills, foot, gonad, muscle, byssus, and remaining soft tissues) of the green-lipped mussel Perna viridis, collected from eight geographic locations along the coastal waters of peninsular Malaysia. The STs of the mussels collected from the eastern part of ...

abstract polycyclic aromatic hydrocarbons (pahs) are classified as persistent and carcinogenic organic pollutants. pahs contamination has been reported in water. many of relevant regulatory bodies such as eu and epa have regulated the limit levels for pahs in drinking water. in this study, 13 priority polycyclic aromatic hydrocarbons (pahs) were determined in tap water samples of tehran and wat...

Thiophene-fused polycyclic aromatic hydrocarbons (PAHs) are known to be useful as organic semiconductors due to their high charge transport properties. Scientists at Nagoya University have developed a short route to form various thiophene-fused PAHs by simply heating mono-functionalized PAHs with sulfur. This new method is expected to contribute towards the efficient development of novel thioph...

There is currently scarce information on the occurrence and distributions of Polycyclic Aromatic Hydrocarbons (PAHs) in the air from industrial estates in Nigeria. Hence, the present study aims to evaluate the extent and sources of pollution of polycyclic aromatic hydrocarbons in the air from some industrial estates in Lagos and Ogun States, Nigeria. Ten air samples have been collected from the...

Identification and quantification of 16 priority Polycyclic Aromatic Hydrocarbons (PAHs) collected from 4 atmosphere particulate samples in December 2008 to January 2009 were determined by gas chromatography (GC). The source of the PAHs in atmosphere particulate was estimated by chemical mass balance model and improved source apportionment technique. Dust was the major PAHs source in Qingdao, a...

Biodegradation of polycyclic aromatic hydrocarbons (PAHs) in crude oil, by a white rot fungus, Pleurotus ostreatus sp., in broth culture was investigated. It was found that the biomass of the organism increased with the increase of PAHs concentration in the cultures. In the cultures with 25.99, 49.01 and 80.05 mg.kg-1 PAHs, the degradation increased with the PAHs of low molecular weight concent...

Finding an environment-friendly and affordable method to remove contaminated soils from Polycyclic Aromatic Hydrocarbons (PAHs) has now become an attractive field for researchers, with super-critical fluid extraction being an innovative process in the field of contaminated soil treatment. Extraction with super-critical fluid is a simple and rapid extraction process that uses super-critical flui...

Background and Objectives: A method was developed and validated for determining 15 polycyclic aromatic hydrocarbons (PAHs) in refined olive and refined pomace olive oils using high performance liquid chromatography coupled with a fluorescence detector. Materials and Methods: The sample preparation involved liquid–liquid extraction with organic solvent and low temperature clean-up. The low temp...
