Polycyclic aromatic hydrocarbons (PAHs) are considered to be a group of compounds that pose potential health hazards since some PAHs are known carcinogens. During coal utilization processes, such as coal combustion and pyrolysis, PAHs released may be divided into two categories according to their formation pathways. One category is derived from complex chemical reactions and the other is from f...

Many polycyclic aromatic hydrocarbons (PAHs) are known carcinogens, and a considerable amount of research has been devoted to predicting the tumor-initiating potential of PAHs based on chemical structure. However, there has been little research into the effects of PAHs on the epigenetic events of tumor promotion and no structural correlation has been made thereof. Gap junctional intercellular c...

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...

Polycyclic aromatic hydrocarbons (PAHs), abundant in mixed contaminant sites, often coexist with heavy metals. The fate and remediation of PAHs depend heavily on the sorption and desorption behavior of these contaminants. The sorption behavior can in turn be highly affected by certain soil components and properties, such as soil organic matter (SOM) and the presence of heavy metals. Through rev...

This study was designed to determine concentrations of polycyclic aromatic hydrocarbons (PAHs) in soil samples collected from Midway Atoll and evaluate their potential risks to human health. The total concentrations of 16 PAHs ranged from 3.55 to 3200 µg kg(-1) with a mean concentration of 198 µg kg(-1). Higher molecular weight PAHs (4-6 ring PAHs) dominated the PAH profiles, accounting for 83....

Polycyclic aromatic hydrocarbons (PAHs) are attracting concern because of their potential toxicity, posing serious threats to health of humans and ecosystems (Kim et al., 2013; Zhao et al., 2016). Generally, similar to other contaminants' behaviors (Wu et al., 2001; Zhang et al., 2007, 2008; Lu et al., 2009), PAHs result from natural organic matter and activities of humans, the latter's contrib...

Text: Polycyclic aromatic hydrocarbons (PAHs) consist of two or more carbon-hydrogen rings in which at least one ring has an aromatic structure. . PAHs are known to have important carcinogenic and mutagenic effects. Furthermore, these compounds can undergo photo chemically induced oxidation and nitration reactions with reactive oxygen species (ROSs) [e.g., ozone (O3) and radicals such as single...

The objective of the present study was to characterise the polycyclic aromatic hydrocarbons (PAHs) content of an aged contaminated soil and to propose remediation techniques using cyclodextrins (CDs). Four CDs solutions were tested as soil decontamination tool and proved more efficient in extracting PAHs than when an aqueous solution was used; especially two chemically modified CDs resulted in ...
