Sources and distribution of aliphatic and polyaromatic hydrocarbons in sediments from the Neuquén River, Argentine Patagonia
(Taylor & Francis, 2013-02)
Spatial distribution and probable sources of aliphatic and polyaromatic hydrocarbons (AHs, PAHs) were investigated in surface sediments collected along the bank of the Neuquen River, Argentina. Total concentrations of ...
Hidrocarbonetos policíclicos aromáticos em sedimentos de fundo do estuário do rio Potengi, região da grande Natal (RN): implicações ambientais
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia do PetróleoPesquisa e Desenvolvimento em Ciência e Engenharia de Petróleo, 2011-02-07)
Estuaries are environments prone to the input of chemical pollutants of various kinds
and origins, including polycyclic aromatic hydrocarbons (PAHs). Anthropogenic PAHs
may have two possible sources: pyrolytic (with four ...
Determinação de fontes de hidrocarbonetos policíclicos aromáticos e alifáticos em sedimentos de ambientes aquáticos
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2006-04-20)
Numerical values of polycyclic aromatic hydrocabons and n-alkanes distribution indexes of
sediments are important tools to elucidate the origins of hydrocarbons mixtures. Polycyclic
aromatic ratios are sensitive indicators ...

The of Serrinha plutonic suite, northeastern portion of the Borborema Province (NE Brazil), is characterized by a voluminous and diversified magmatism of Neoproterozoic age, intrusive in the Archean to Paleoproterozoic ...
Hidrocarbonetos policíclicos aromáticos no meio ambiente: diferenciação de fontes em sedimentos e metabólitos em bile de peixes
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em QuímicaFísico-Química; Química, 2007-03-30)
Many studies on environmental ecosystems quality related to polycyclic aromatic hydrocarbons (PAH) have been carried out routinely due to their ubiquotus presence worldwide and to their potential toxicity after its ...
Hidrocarbonetos alifáticos em sedimentos de fundo do estuário do Rio Potengi, grande Natal (RN): implicações ambientais
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia do PetróleoPesquisa e Desenvolvimento em Ciência e Engenharia de Petróleo, 2011-02-07)
The Potengi river estuary is located in the region of Natal (RN, Brazil), comprising a population of approximately 1,000,000 inhabitants. Besides the dominant urban presence, the estuary has fragments of mangrove forest. ...
Sources and distribution of aliphatic and polyaromatic hydrocarbons in coastal sediments from the Ushuaia Bay (Tierra del Fuego, Patagonia, Argentina)
(Elsevier, 2011-12)
The environmental quality of Ushuaia Bay, located at the southernmost tip of South America, is affected by the anthropogenic pressure of Ushuaia city. In this study, levels and sources of hydrocarbons in coastal sediments ...
Persistent toxic substances in surface water of Todos Os Santos Bay, Brazil
(2012)
Persistent toxic substances (PTSs) such as polycyclic aromatic hydrocarbons (PAHs) are of great concern due to their persistence, bioaccumulation and toxic effects. In this work, 14 PAHs included in the US Environmental ...
Variação espacial e temporal de uma taxocenose de caprelídeos (Crustacea: Amphipoda) em um ecossistema subtropical sujeito à poluição por hidrocarbonetos de petróleo
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2010-06-11)
The petroleum demand, as so as the commerce of its derivates, has caused the introduction of these compounds in marine ecosystems. The transportation and the extraction of petroleum cause severe accidents, impacting coastal ...
