Polycyclic aromatic hydrocarbons (PAHs) have been widely studied with respect to their carcinogenic and mutagenic effects on animals and human cells. Phenanthrene (PHE) and fluoranthene (FLU) effects on the needle photosynthetic traits of 2-year-old Japanese red pine (Pinus densiflora Sieb. et. Zucc.) seedlings were investigated. Three months after fumigation of foliage with solutions containin...

Thirty atmospheric dustfall samples collected from an industrial corridor in Hubei Province, central China, were analyzed for 16 USEPA priority polycyclic aromatic hydrocarbons (PAHs) to investigate their concentrations, spatial distributions, sources, and health risks. Total PAH concentrations (ΣPAHs) ranged from 1.72 to 13.17 µg/g and averaged 4.91 µg/g. High molecular weight (4-5 rings) PAHs...

We collected soil samples at 23 sites from the petroleum contaminated soils (PC) in the west of Kermanshah province to investigate the sources and ecological risk of polycyclic aromatic hydrocarbons (PAHs). In this study, source apportionment has been carried out using Positive Matrix Factorization (PMF).The total PAHs concentration, have a mean value of 92.79 mg/kg, ranging from 7.37 to 609.67...

Integrating bioavailability into risk assessments is an effective way to objectively assess human health risks. In this study, the of 16 polycyclic aromatic hydrocarbons (PAHs) in contaminated soil from a coking plant was evaluated using polydimethylsiloxane (PDMS) passive sampling method. The results showed that factor (BAF) each PAH, predicted PDMS fibers, ranged 0.46% 9.74%. method more stab...

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...

Total suspended particulate matter (TSPM) samples were collected at Nunhai, Agra from May 2006 to September 2006. Since polycyclic aromatic hydrocarbons (PAHs) are known carcinogenic and mutagenic, concentrations of 16 PAHs in aerosols were quantified in the present paper. The dominating PAHs in TSPM include high molecular weight Benzo(ghi)Perylene, dibenzo(b)anthracene, indeno(123cd) pyrene, b...

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous; some of them have been paid more attention due to their carcinogenic and mutagenic properties. Atmospheric deposition is an important process for air-surface exchange of polycyclic aromatic hydrocarbons (PAHs). A yearround bulk (wet plus dry) deposition sampling campaign in mountain, plain, and basin sites was conducted in Chengdu Economic...

Tobacco smoke is a major source of human exposure to polycyclic aromatic hydrocarbons (PAHs). The concentration of PAHs in lung tissue would reflect an individual's dose, and its variation could perhaps reflect cancer risk. Eleven PAHs were measured in 70 lung tissue samples from cancer-free autopsy donors by gas chromatography-mass spectrometry. There were 37 smokers and 33 nonsmokers as estim...

Polycyclic aromatic hydrocarbons (PAHs) are frequently detected in soil. Their biological toxicity and carcinogenic, teratogenic, mutagenic effects pose a great threat to the ecological environment human health. Firstly, sources, physicochemical properties, environmental hazards of PAHs reviewed this paper, then their pollution status different methods for detection soil described detail. The r...
