Polycyclic aromatic hydrocarbons (PAHs) leachates from cigarette butts into water.

Environmental Pollution, 2020
Cigarette butts (CBs) are the most common littered items in the environment and may contain high amounts of polycyclic aromatic hydrocarbons (PAHs) from incomplete tobacco leave burning.

Polyaromatic Hydrocarbons (PAHs): Structures, Synthesis and their Biological Profile.

Current Organic Synthesis, 2020
Polycyclic aromatic hydrocarbons (PAHs) are aromatic compounds with two or more fused benzene rings in their structural configurations. PAHs do not contain hetero atoms and substituents on the ring system.

Pah Pum

Proceedings of the XXXIV Brazilian Symposium on Software Engineering, 2020
This article presents Pah Pum, a project management tool based on Takt PM, a hybrid project management methodology. The tool was developed at SENAI Institute of Innovation for Information and Communication Technologies to facilitate adherence to Takt PM, offering processes systematization and using best practices suggested by the methodology.

PAH-pools in soils along a PAH-deposition gradient

Environmental Pollution, 1996
The objectives of this study are to characterize different PAH-pools (soil horizons, microsites influenced by stem flow, aggregate core and surface fractions, particle size fractions) in soils affected by depositions. Three forest soils affected by the emissions of an aluminium plant near Ziar/Central Slovakia were sampled to analyze 20 PAHs.

PM2.5-bound polycyclic aromatic hydrocarbons (PAHs) and their derivatives (nitrated-PAHs and oxygenated-PAHs) in a road tunnel located in Qingdao, China: Characteristics, sources and emission factors.

Science of the Total Environment, 2020
Daytime and nighttime PM2.5 samples were collected at a road tunnel located in Qingdao, China. The mass concentrations and chemical compositions of polycyclic aromatic hydrocarbons (PAHs), nitrated PAHs (NPAHs) and oxygenated-PAHs (OPAHs) were analysed ...

Enhancement of PAHs biodegradation in biosurfactant/phenol system by increasing the bioavailability of PAHs.

Chemosphere, 2020
The poor bioavailability of polycyclic aromatic hydrocarbons (PAHs) is the main limiting factor for their biodegradation in contaminated sites. The addition of biosurfactant is an effective method for enhancing the bioavailability of PAHs.

The cellular effects of PM2.5 collected in Chinese Taiyuan and Guangzhou and their associations with polycyclic aromatic hydrocarbons (PAHs), nitro-PAHs and hydroxy-PAHs.

Ecotoxicology and Environmental Safety, 2020
Numerous studies have demonstrated adverse effects on human health after exposure to fine particulate matter (PM2.5). However, it is still not clear how the toxicological effects and the health risks vary among PM samples of different compositions and ...
