Mutagenicity assessment of aerosols in emissions from wood combustion [PDF]

open access: yes, 2011
Mestrado em Estudos AmbientaisPolycyclic aromatic hydrocarbon (PAH) extracts of PM2.5 collected from combustion of seven wood species and briquettes were tested for mutagenic activities using Ames test with Salmonella typhimurium TA98 and TA100.

From planes to bowls: photodissociation of the bisanthenequinone cation

open access: yes, 2018
We present a combined experimental and theoretical study of the photodissociation of the bisanthenequinone (C28H12O2) cation, Bq+. The experiments show that, upon photolysis, the Bq+ cation does not dehydrogenate, but instead fragments through the ...

Investigation of NQO1 genetic polymorphism, NQO1 gene expression and PAH-DNA adducts in ESCC. A case-control study from Iran [PDF]

open access: yes, 2009
We evaluated the effect of NQO1 genetic variation on PAH-DNA adducts in esophageal squamous cell carcinoma (ESCC) in northeast Iran. Golestan Province in northeast of Iran has one of the highest esophageal cancer incidences in the world.

Polycyclic Aromatic Hydrocarbons in Corn Grains

open access: yesBulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Food Science and Technology, 2019
Contamination of crop plants with organic pollutants raises a growing interest in recent years; among the investigated pollutants, polycyclic aromatic hydrocarbons (PAHs) are of special concern because some of them are toxic and carcinogenic.

Role of Kekul\'e and Non-Kekul\'e Structures in the Radical Character of Alternant Polycyclic Aromatic Hydrocarbons: A TAO-DFT Study

open access: yes, 2016
We investigate the role of Kekule and non-Kekule structures in the radical character of alternant polycyclic aromatic hydrocarbons (PAHs) using thermally-assisted-occupation density functional theory (TAO-DFT), an efficient electronic structure method ...

Identification of polycyclic aromatic hydrocarbons [PDF]

open access: yes
The nature of the Very Small Grains evidenced by K. Sellgren (1985) is discussed. Thsir stability suggests that they are graphitic material and specifically Polycyclic Aromatic Hydrocarbons (PAHs).

Sand to Root Transfer of PAHs and PCBs by Carrots Grown on Sand with Pure Substances and Biosolids Amended Sand [PDF]

open access: yes, 2006
A study on behaviour of trace organic compounds (Polycyclic Aromatic Hydrocarbons, PAH, and Polychlorinated Biphenyls, PCB) in a sand-plant system has been carried out, with the reclamation of wastewater treatment plant biosolids for agriculture in mind.
