Abundance, dynamics, and biogeographic distribution of seven Polycyclic aromatic hydrocarbon dioxygenase gene variants in coastal sediments of Patagonia
(American Society for Microbiology, 2012-02)
Novel polycyclic aromatic hydrocarbon dioxygenase gene variants were present in abundances similar to or higher than those of phnA1 from Cycloclasticus spp. at a chronically polluted subantarctic coastal marine environment ...
Co-treatment of an oily sludge and aged contaminated soil: permanganate oxidation followed by bioremediation
(Academic Press Inc Elsevier Science, 2020-05-01)
The bioremediation of an oily sludge (321 ± 30 mg of polycyclic aromatic hydrocarbons/kgDRY SLUDGE and 13420 ± 1300 mg of aliphatic hydrocarbons/kgDRY SLUDGE) by mixture with contaminated soil (23 ± 2 mg of polycyclic ...
Dispersive liquid–liquid microextraction based on solidification of floating organic drop and fluorescence detection for the determination of nitrated polycyclic aromatic hydrocarbons in aqueous samples
(Elsevier Science, 2017-03)
In this study, a dispersive liquid–liquid microextraction method based on the solidification of a floating organic drop (DLLME-SFO) combined with molecular fluorescence detection was developed for the analysis of nitrated ...
Polycyclic Aromatic Hydrocarbons (PAHs) in “Yerba Mate” (Ilex paraguariensis) Fractions
(Taylor & Francis Ltd, 2018-12)
The aim of this study was to evaluate polycyclic aromatic hydrocarbons (PAHs) contamination, distribution, and toxicity in “yerba mate” fractions, and to propose actions to reduce its pollution. Sixteen PAHs were quantified ...
Oxidized metabolites from cyclopenta-fused polycyclic aromatic hydrocarbons (CP-PAHs). A DFT model study of their carbocations formed by epoxide ring opening
(John Wiley & Sons Ltd, 2010-03)
A density functional theory (DFT) study aimed at understanding structure-reactivity relationships in the oxidized metabolites of cyclopenta-fused polycyclic aromatic hydrocarbons (CP-PAHs) is reported. Epoxidation at various ...
Biomarker Responses to Polycyclic Aromatic Hydrocarbons in the Native Fish Ramnogaster arcuata, South America
(University of Tehran, 2019-02)
Quantification of polycyclic aromatic hydrocarbons (PAHs) in Bahía Blanca Estuary (BBE, Argentina) fish samples (Ramnogaster arcuata) was performed to evaluate the environmental impact through anthropogenic activity. In ...
First evidence of polycyclic aromatic hydrocarbons in sediments from a marine protected area within Argentinean Continental Shelf
(Pergamon-Elsevier Science Ltd, 2020-09)
This study evaluated for the first time, the distribution, sources, and ecological risk assessment of 16 polycyclic aromatic hydrocarbons (PAHs) in sediments collected along the northern Patagonian shelf in the Argentine ...
Different behaviours in the solubilization of polycyclic aromatic hydrocarbons in water induced by mixed surfactant solutions
(Pergamon-Elsevier Science Ltd, 2011-09-24)
Water solubility of polycyclic aromatic hydrocarbons (PAHs), viz, naphthalene and phenanthrene, in micellar solutions at 25°C was investigated, using two series of different binary mixtures of anionic and nonionic surfactants. ...
Biodegradation of polycyclic aromatic hydrocarbons (PAHs) by fungal enzymes: A review
(Science Press, 2017-01)
Polycyclic aromatic hydrocarbons (PAHs) are a large group of chemicals. They represent an important concern due to their widespread distribution in the environment, their resistance to biodegradation, their potential to ...
Reduction of polycyclic aromatic hydrocarbons promoted by cobalt or manganese nanoparticles
(Pergamon-Elsevier Science Ltd, 2010-06)
A new methodology for the partial reduction of polycyclic aromatic and heteroaromatic hydrocarbons under mild reaction conditions is presented, the process being a reasonable alternative to the catalytic hydrogenation or ...
