On the catalytic hydrogenation of polycyclic aromatic hydrocarbons into less toxic compounds by a facile recoverable catalyst
(ELSEVIER SCIENCE BV, 2009)
Here we present the catalytic hydrogenation of polycyclic aromatic hydrocarbons (PAHs) to less toxic mixtures of saturated and partial unsaturated polycyclic hydrocarbons under mild reaction conditions using a magnetically ...
Concentration and composition of polycyclic aromatic hydrocarbons (PAHs) in plastic pellets: Implications for small-scale diagnostic and environmental monitoring
(London, 2013-11-15)
Plastic pellets may serve as a carrier of toxic contaminants, including polycyclic aromatic hydrocarbons (PAHs). Considering that beach morphodynamics and pellet distribution varied along the shore, and that contaminant ...
Methodology for the extraction, clean-up and quantification of polycyclic aromatic hydrocarbons in urban particulate matter.
(SOCIEDAD CHILENA DE QUIMICA, 2002-12)
A reliable methodology for identification and quantification of Polycyclic Aromatic Hydrocarbons (PAHs) in atmospheric aerosols has been developed, using extraction with dichloromethane, a clean-up step for purification ...
Identification of polycyclic aromatic hydrocarbons in sugar cane soot by gas chromatography mass spectrometry
(Vieweg, 1997-12-01)
Fly soot samples collected in the sugar cane fields after the process of burning were extracted in a Soxhlet apparatus (methylene chloride:methanol 4:1). The extracts were fractionated on silica gel Sep-Pak cartridges into ...
First evidence of Dinophysistoxin-1 ester and carcinogenic polycyclic aromatic hydrocarbons in smoked bivalves collected in the Patagonia fjords
(2004)
Diarrhetic shellfish poisoning (DSP) is a gastrointestinal disease caused by fat-soluble polyether toxins produced by dinoflagellates and accumulated in shellfish. Up to the present, only four fat-soluble polyethers have ...
Polycyclic aromatic hydrocarbons (PAHs) and their polar derivatives (oxygenated PAHs, azaarenes) in soils along a climosequence in Argentina
(Elsevier Science, 2014-12-27)
We evaluated the effects of soil properties and climate on concentrations of parent and oxygenated polycyclic aromatic compounds (PAHs and OPAHs) and azaarenes (AZAs) in topsoil and subsoil at 20 sites along a 2100-km north ...
A one-century sedimentary record of N- and S-polycyclic aromatic compounds in the Athabasca oil sands region in Canada
(Elsevier, 2020)
The atmospheric deposition of polycyclic aromatic compounds (PACs) is considered a major pathway to isolated lakes and bogs in the Athabasca oil sands region (AOSR), Canada. However, the suite of PACs measured has been ...
