“…The distribution of PAHs in the surficial sediment sample (0 to 2 cm) was similar to those reported in other studies conducted in Brazil (Santanna et al, 2010;Nishigima et al, 2001;Zanardi et al, 1999). This is the first report to our knowledge of the temporal distribution of the PAHs in Curitiba, although their distribution in surface sediments of the Barigui River has been described (Froehner et al, 2012).…”

“…Both grain size and total organic carbon have been shown to be important factors in sediment PAH distribution. 13,14 This may explain the variations in the organic extract percentage in the different sediment types. The sediment of Lake de Cima, which has the highest organic extract percentage (0.4%, the Imbé and the Ururaí sediments have lower carbon contents and organic extract percentage (0.009% and 0.042%, respectively) than the sediments of Lake de Cima and the Urubu (Table 1).…”

“…The total PAH concentration in the Lake de Cima is far below the observed values in sediments from many sites in the world, riverine or marine, Figure 4. The Cotonou lagoon sediment samples (Benin) 47 exhibited total PAH concentrations in the range 25-1,450 ng g -1 , the Aquitaine (France) 47 in the range 4-855 ng g -1 , the Yenisey River (Russia) 48 in the range 22-810 ng g -1 , Ob River (Russia) 49 in the range 24-115 ng g -1 , Kara Sea (Russia) 49 in the range 16-94 ng g -1 , the Bayou St. John (New Orleans, USA) 50 was 10,300 ng g -1 , the Detroit and Rouge Rivers (Michigan, USA) 51 in the range 17-44,000 ng g -1 , the Atibaia River (São Paulo, Brazil) 52 in the range 10-398 ng g -1 , the Santos (São Paulo, Brazil) 13 in the range 80-42,390 ng g -1 , in Capibaribe River (Pernambuco, Brazil) 19 in the range 188-906 ng g -1 , in Xiamen Harbor (China) 53 in the range 247-480 ng g -1 . Total PAH values in excess of 10,000 ng g -1 were found in estuarine sediments from the Rivers Tyne, Wear and Tees, and up to 102,471 ng g -1 in Millford (UK).…”

Foram estudados sedimentos recentes dos rios Imbé, Urubu e Ururaí e da Lagoa de Cima, localizados no município de Campos dos Goytacazes, Rio de Janeiro. As frações dos hidrocarbonetos alifáticos e aromáticos foram analisadas por CG-DIC e CG-EM com o objetivo de se verificar o grau de contaminação por atividades antropogênicas ou contribuições biogênicas. A concentração total dos hidrocarbonetos alifáticos e aromáticos foram 1,2 , 2,8 , 5,8 e 4,3 µg g -1 e 74 , 30 , 722 e 340 ng g -1 para os rios Imbé, Ururaí, Urubu e Lagoa de Cima, respectivamente. O isoprenóide C 20 foi identificado no sedimento do Rio Urubu. Em nenhuma das amostras foram encontrados hopanos e esteranos. Compostos aromáticos antropogênicos, detectados ao nível de traços, foram observados somente no rio Imbé e na Lagoa de Cima (227 ng g -1 ). A razão fluoranteno/pireno foi de 4,2 para a Lagoa de Cima, sugerindo uma origem por combustão para os HPA. Este fato é consistente com a prática de queimada de plantações de cana de açúcar que ocorre freqüentemente nesta região. Um grande aporte de plantas superiores foi observado nos sedimentos dos rios Urubu, Imbé e da Lagoa de Cima; por outro lado o aporte predominante no rio Ururaí foi o aquático. A Lagoa de Cima é considerada levemente poluída por HPA, ao nível de traços, enquanto os demais sedimentos não se encontram poluídos.Sediment samples from the Imbé, the Urubu and the Ururaí rivers and from Lake de Cima were studied. These sites are located in the county of Campos dos Goytacazes, Rio de Janeiro, Brazil. Aliphatic and aromatic fractions were analyzed by GC-FID and GC-MS in order to gather information on the degree of contamination by anthropogenic activities and other biogenic contributions. Concentrations of total aliphatic and aromatic hydrocarbons were 1.2, 2.8, 5.8 and 4.3 µg g -1 and 74, 30, 722 and 340 ng g -1 in the Imbé, Ururaí, Urubu rivers and Lake de Cima, respectively. The C 20 highly branched isoprenoid alkane was identified in the Urubu sediment. There were no hopanes or steranes in any sample. Anthropogenic aromatic compounds, detected at trace levels, were observed only in the Imbé and in Lake de Cima (227 ng g -1 ). The fluoranthene/pyrene rate for Lake de Cima was 4.2, suggesting a combustion origin for the PAH. This data is consistent with the frequently sugar cane burning practice that occurs in this region. A greater input from higher plants was observed in the Urubu, Imbé and Lake de Cima sediments; on the other hand, the aquatic input predominates for Ururaí. In summary, Lake de Cima sediment is considered very slightly polluted, while the others are unpolluted. Keywords: hydrocarbons, sediments, PAH, isoprenoid, (C/N) ratios, organic matter IntroductionRecent sediments of natural waters contain variable amounts of organic matter, ranging from less than 1% up to 8% of dry sediment, 1 but are considered rich when they have more than 0.5% of organic matter. 2 It is difficult to obtain detailed information about the sources and transformations of this organic matter by deter...
