Polycyclic Aromatic Hydrocarbons: Sources, Toxicity, and Remediation Approaches
Frontiers in Microbiology, 2020 Polycyclic aromatic hydrocarbons (PAHs) are widespread across the globe mainly due to long-term anthropogenic sources of pollution. The inherent properties of PAHs such as heterocyclic aromatic ring structures, hydrophobicity, and thermostability have ...

Alteration and release of aliphatic compounds by the polychaete Nereis virens (Sars) experimentally fed with hydrocarbons [PDF]
, 2001 In the laboratory, marine worms were fed with a mixture of algae and several aliphatic hydrocarbons for 15 days. After ingestion by the worms, 34.9% of hydrocarbons are found in the faeces and only 3.1% accumulated in the gut.

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

A five year record of high-frequency in situ measurements of non-methane hydrocarbons at Mace Head, Ireland [PDF]
, 2011 Continuous high-frequency in situ measurements of a range of non-methane hydrocarbons have been made at Mace Head since January 2005. Mace Head is a background Northern Hemispheric site situated on the eastern edge of the Atlantic. Five year measurements

Atomic displacements due to spin–spin repulsion in conjugated alternant hydrocarbons [PDF]
, 2013 We develop a theoretical model to account for the spin-induced atomic displacements in conjugated alternant hydrocarbons. It appears to be responsible for an enlargement of the distance between pairs of atoms separated by two atoms and located at the end

Bioelectrochemical remediation of petroleum hydrocarbons
, 2021 Aims There is interest in cleaning up hydrocarbon contaminated sites via bioremediation as the process is environmentally friendly and sustainable. However, some of the bioremediation methods are very slow and expensive, often limited by the availability

Atmospheric polycyclic aromatic hydrocarbons: Source attribution, emission factors and regulation
, 2008 There is an increasing concern about the occurrence of polycyclic aromatic hydrocarbons (PAHs) in the environment as they are ubiquitous in ambient air and some of them are among the strongest known carcinogens. PAHs and their derivatives are produced by
