Polycyclic Aromatic Hydrocarbons (PAHs)
Polycyclic aromatic hydrocarbons (PAHs) are toxic substances that undergo bioaccumulation and can be found in various forms, including coal tar, fossil fuel burning, forest fires, grilling meats over open fires, cigarette smoke, diesel emissions, asphalt surfaces, tar roofs, aluminum and coke plants, and more.Serban Moldoveanu, Robert Owen Bussey

Polycyclic Aromatic Hydrocarbon (PAH) Degradation Coupled to Methanogenesis
Biotechnology Letters, 2006Baltimore Harbor (Baltimore, MD) sediments were utilized to initiate anaerobic enrichment cultures with polycyclic aromatic hydrocarbons (PAHs) in the absence of supplementary electron acceptors. Cultures amended with naphthalene and phenanthrene exhibited sustained, transferable degradation of the PAHs.

Review on polycyclic aromatic hydrocarbons (PAHs) migration from wastewater
Journal of Contaminant Hydrology, 2021Rapidly increasing global population and increased civilization has increased burden on potable water resources and results in larger volumes of wastewater. Physical wastewater management techniques has advanced for domestic usage and commercial effluent new conceptions about imminent wastewater treatment have been acclaimed for highly carcinogenic ...

Polycyclic aromatic hydrocarbons (PAHs) in mangrove ecosystems: A review
Environmental Pollution, 2022Polycyclic aromatic hydrocarbons (PAHs) are organic pollutants of increasing concern in the different fields of the environment and human health. There are 16 of them that are recognized as priority pollutants by the US environmental protection agency due to their mutagenic and carcinogenic potentials.

Infrared spectra of polycyclic aromatic hydrocarbons (PAHs)
Chemical Physics, 2000We have computed the synthetic infrared spectra of some polycyclic aromatic hydrocarbons containing up to 54 carbon atoms. The species studied include ovalene, circumcoronene, dicoronylene, and hexabenzocoronene. We report spectra for anions, neutrals, cations, and multiply charged cations.

Polycyclic aromatic hydrocarbons (PAHs) in Chicago air
Science of The Total Environment, 1999Ambient air samples were collected in Chicago, IL between June and October 1995 as part of a study to investigate the dry deposition and air–water exchange of polycyclic aromatic hydrocarbons (PAHs). A modified high-volume sampler (PS-1 sampler) was used to collect airborne PAHs in both the particulate and gas phases. The average total (gas+particulate)

Mechanisms for polycyclic aromatic hydrocarbon (PAH) growth
Chemical Physics Letters, 2000Abstract We compute the barriers and heats of reaction for the conversion of benzene to naphthalene by acetylene additions using the B3LYP/4-31G approach. The Frenklach mechanism for adding a ring to a PAH molecule is compared with the Bittner–Howard acetylene addition mechanism. Both have low barriers, and the similarities and differences of the two

Polycyclic Aromatic Hydrocarbon (PAH) Ecotoxicology in Marine Ecosystems
Journal of Toxicology and Environmental Health, Part A, 2006Low levels of oil and hence polycyclic aromatic hydrocarbons (PAHs) are naturally present in the marine environment, although levels have increased significantly following human extraction and use of oil and gas. Other major anthropogenic sources of PAHs include smelters, the use of fossil fuels in general, and various methods of waste disposal ...

IMMUNOCHEMICAL DETECTION OF POLYCYCLIC AROMATIC HYDROCARBONS (PAHs)
Analytical Letters, 2002This review gives a short introduction in the origin, occurrence and detection of polycyclic aromatic hydrocarbons (PAHs). Emphasis lies on immunochemical detection methods for PAH compounds, such as ELISA, RIA, fluoroimmunosensors, QCM immunosensors and electrochemical immunosensors, but also on immunosorbents and commercial immunoassay kits for PAHs.

Sorption of polycyclic aromatic hydrocarbons (PAHs) on glass surfaces
Chemosphere, 2011Sorption of polycyclic aromatic hydrocarbons (PAHs) to glass commonly used in laboratories was studied. Sorption coefficients (Kd) of five selected PAHs to borosilicate glass surfaces were measured using column chromatography. A linear relationship between log Kd and the corresponding water solubility of the subcooled liquid (log Sw) of the ...
