Spatial distribution and sources of PAHs in topsoil in the Beiyun River Basin (Beijing section)

open access: yesShuiwen dizhi gongcheng dizhi, 2023
Organic pollution of polycyclic aromatic hydrocarbons (PAHs) in topsoil has threatened human health and ecological environment. In order to understand the distribution and pollution characteristics of PAHs in topsoil in the Beiyun River Basin in Beijing,

Biodegradation of Mixed PAHs by PAH-Degrading Endophytic Bacteria [PDF]

open access: yesInternational Journal of Environmental Research and Public Health, 2016
Endophytic bacteria can promote plant growth, induce plant defence mechanisms, and increase plant resistance to organic contaminants. The aims of the present study were to isolate highly PAH-degrading endophytic bacteria from plants growing at PAH-contaminated sites and to evaluate the capabilities of these bacteria to degrade polycyclic aromatic ...

Investigation of PAHs, nitrated PAHs and oxygenated PAHs in PM10 urban aerosols. A comprehensive data analysis

open access: yesChemosphere, 2022
Polycyclic aromatic compounds (PACs) in particulate matter contribute considerably to the health risk of air pollution. As such, we have optimized a method to determine the levels of polycyclic aromatic hydrocarbons, especially nitrated and oxygenated polycyclic aromatic hydrocarbons, in samples of PM10 particulate matter using microwave-assisted ...

Differences between Pinus pinea and Pinus pinaster as bioindicators of polycyclic aromatic hydrocarbons [PDF]

open access: yes, 2011
The potential of Univariate and Multivariate Analysis and specifically Principal Components Analysis (PCA), has been employed to assess the performance of pine needles as bioindicators of polycyclic aromatic hydrocarbons (PAHs) and particularly emphasize

Emissions of gas- and particle-phase polycyclic aromatic hydrocarbons (PAHs) in the Shing Mun Tunnel, Hong Kong [PDF]

open access: yes, 2009
Real-world vehicle emission factors for seventeen gas and particulate polycyclic aromatic hydrocarbons (PAHs) were quantified in the Shing Mun Tunnel, Hong Kong during summer and winter 2003.

Fate of polycyclic aromatic hydrocarbons during composting of lagooning sewage sludge [PDF]

open access: yes, 2005
The fate of 16 polycyclic aromatic hydrocarbons (PAHs), targeted by the USEPA agency, has been investigated during composting of lagooning sludge. Composting shows efficient decrease of the content and the bioavailability of each PAH.

Nitrated polycyclic aromatic hydrocarbons (nitro-PAHs) in the environment – A review [PDF]

open access: yes, 2017
Nitrated polycyclic aromatic hydrocarbons (nitro-PAHs) are derivatives of PAHs with at least one nitro-functional group (-NO2) on the aromatic ring. The toxic effects of several nitro-PAHs are more pronounced than those of PAHs.

Effects of different agricultural wastes on the dissipation of PAHs and the PAH-degrading genes in a PAH-contaminated soil [PDF]

open access: yesChemosphere, 2017
Land application of agricultural wastes is considered as a promising bioremediation approach for cleaning up soils contaminated by aged polycyclic aromatic hydrocarbons (PAHs). However, it remains largely unknown about how microbial PAH-degraders, which play a key role in the biodegradation of soil PAHs, respond to the amendments of agricultural wastes.
