Identification of polycyclic aromatic hydrocarbons and methoxylated phenols in wood smoke emitted during production of charcoal
More than 130 organic substances in dichloromethane-methanol (4: 1) extracts of particulate matter and the gaseous phase from wood burning for the production of charcoal have been identified by capillary gas chromatography ...
Identification of polycyclic aromatic hydrocarbons in sugar cane soot by gas chromatography mass spectrometry
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 ...
Reconstruction and in silico analysis of new Marinobacter adhaerens t76_800 with potential for long-chain hydrocarbon bioremediation associated with marine environmental lipases
Marinobacter is a Gammaproteobacterium and member of the family Alteromonadaceae. Some Marinobacter species degrade hydrocarbons and aromatic compounds, raising the possibility of applications in marine bioremediation. ...

Cuticular Hydrocarbon Variation of Castes and Sex in the Weaver Ant Camponotus textor (Hymenoptera: Formicidae)
(CALIFORNIA STATE UNIVCHICO, 2012)
Cuticular hydrocarbons play important roles as chemical signatures of individuals, castes, sex and brood. They also can mediate the regulation of egg laying in ants, by informing directly or indirectly the reproductive ...
Data on hydrocarbons in sediment samples, and its body burden levels in tissues of Anomalocardia flexuosa from toxicity testing
The analysis of hydrocarbons in terms of individual compounds is relevant to understand the origin and source of these substances, as well as its distribution in environmental compartments, including sediments and biota. ...
Natural and anthropogenic hydrocarbons in sediments from the Chubut River (Patagonia, Argentina)
(Pergamon-Elsevier Science Ltd, 2004-05)
In march of 2001 a study was carried out to evaluate hydrocarbon levels in the lower course of the Chubut River. The study included 12 sample stations along the river from San Cristobal Bridge to the confluence with the ...

(Universidad de Chile, 2014-11-13)
This report explores the question: Why do foreign oil companies continue operate in exploration and production activities in Bolivia’s hydrocarbon industry after its 2006 nationalization? The history of Bolivia’s hydrocarbon ...
Copper removal by Botryococcus braunii biomass with associated production of hydrocarbons
(Scitec Publications, 2013-10)
The goal of the present article is to evaluate the potential of copper(II) removal from acidic wastewater, associated with the production of hydrocarbons by the microalgae Botryococcus braunii. Results demonstrate that the ...
