“…The presence of biomarker hopanes with aβ stereochemistry, widely used as molecular markers for oil pollution, indicated petrogenic inputs at all stations. These petroleum biomarkers were found to be useful for the investigation of petrogenic inputs in sediments (6), South Pier (7), Navegantes Beach (8), Brava Beach (9), discharge Navegantes (10), discharge Brava (11), control sample (12).…”

“…604 are from biogenic, diagenetic, pyrolytic and petrogenic. 10,11 In aquatic environments, hydrocarbons tend to associate with particulate organic matter due to their hydrophobic nature and they are subsequently deposited in the underlying sediments, 12,13 which are recognized as excellent sinks for such pollutants.14 n-Alkanes are commonly used to characterize organic matter from various environments due to their source specificity. Long chain n-alkanes with an odd number of carbons (C 27 -C 35 ) are the main components of epicuticular waxes of higher plants, while aquatic algae are dominated by shorter chain n-alkanes with an odd number of carbons (predominantly C 15 , C 17 and C 19 ).…”

The Itajaí-Açu estuarine system, located in southern Brazil, has great economic importance due to the presence of two ports (Itajaí and Navegantes). This system is affected by industrial and dredging activities, which can cause the remobilization of pollutants accumulated over time in the sediment. In this context, hydrocarbons were assessed in twelve surface sediment samples. n-Alkane and polycyclic aromatic hydrocarbons (PAH) concentrations were determined by gas chromatography and their sources assessed. Total concentrations ranged between 0.50 ± 0.04 and 69.70 ± 3.90 µg g -1 dry weight (d.w.) for n-alkanes and from 63.9 ± 12.1 to 1459.0 ± 43.5 ng g -1 d.w. for PAH. Most of the sediment samples presented carbon preference index (CPI) values close to unity, indicating that the area is submitted to petroleum-related sources, mainly close to Itajaí harbor, where an intense unresolved complex mixture (UCM) was observed. The presence at all stations of aβ-hopane biomarkers also indicated petrogenic input. Based on selected PAH ratios, the sedimentary PAH composition reflects a mixture of both petrogenic and pyrolytic sources. A comparison of the PAH concentrations found in this study with those listed in the sediment quality guidelines (SQGs) indicated that adverse biological effects on the biota are rarely expected.Keywords: aliphatic hydrocarbon, polycyclic aromatic hydrocarbon, biomarker, hopane, contamination IntroductionContamination levels in coastal environments are increasing mainly due to the presence of anthropogenic activities, as waste industrial discharges, industrial activities, navigation traffic, etc.1 Therefore, sediment contamination in such areas may occur. In several countries, port activities are rapidly developing, requiring greater attention, especially in relation to the dredging of contaminated sediments and environmental management. 2,3The Itajaí-Açu estuarine system is located on the north-central coast of Santa Catarina state, in Brazil. This is an area of economic interest not only because of tourism, but also due to the presence of the Port of Itajaí, which is considered the third largest container handling port in Brazil, the major international trading point of the state, and the largest national fishing pole landing site. Associated with this latter activity, several fish processing industries are installed along the margins of this estuary, mainly in the city of Itajaí. These industries dispose their waste products, usually without any treatment, directly into the estuary. [4][5][6][7] In addition, the harbor area is constantly dredged, in order to maintain the navigation channel at an elevation of 11 meters. In May 2011, dredging began to deepen the main river channel, aiming to increase the depth from 11 to 14 meters, allowing the entrance of larger ships. Sediment dredging can cause remobilization of the pollutants accumulated in this compartment over time. 6 O r g a n i c c o m p o u n d s s u c h a s a l i p h a t i c hydrocarbons (AHs) and polycyclic aromatic hydrocarbons (P...

The polycyclic aromatic hydrocarbons (PAHs) are pollutants of concern due to their persistence in the marine ecosystem.The aim of the research was to analyse concentration of Polycyclic Aromatic Hydrocarbons (PAHs) in the sediments and milkfish (Chanos chanos, Forsk) at Marunda and Blanakan ponds.The PAHs fraction were analysed using GC-MS model Shimadzu QP5000.The results revealed that PAH detected in the surface sediments of Marunda and Blanakan Ponds, were Naphthalene, Benzo (b) fluoranthene, Benzo (k) fluoranthene, Benzo (a) pyrene and Indeno (1,2,3-cd) pyrenewith the range concentrations were 27.1~63.0 ng/g and 24.0~64.9 ng/g. Total PAH concentration observed in the meat and gills of Chanos chanos at Marunda ponds were 13.3 ng/g and 0.4 ng/g, respectively, while in Blanakan ponds, PAH were not detected. PAHs were detected in Marunda and Blanakan indicates input source petrogenic and pyrogenic both sediment, meat, and gills of Chanos chanos, Forskal.

“…Therefore, sediments can hold and release pollutants, causing detrimental effects to the biota long after the initial input of pollution has ceased. These contaminants may be released slowly and they may also accumulate in organisms that dwell in and around the sediment (Tolosa et al, 2005). The composition of hydrocarbon compounds found in sediments reflects relatively the origin of such compounds: biogenic, diagenetic, petrogenic and pyrogenic (Wu et al, 2001;Azevedo et al, 2002;Mille et al, 2005).…”

ABSTRACT.p27-33. This paper investigates the presence and concentration levels, of n-alkanes and also the potential sources of contamination of surface sediments in the fishing village Z-3 in the city of Pelotas, Brazil. The extraction of the sediments was performed according to EPA method 3540 and the separation of aliphatic hydrocarbons was done with preparative column chromatography. Gas chromatographic analysis with flame ionization detector was employed for the identification and quantification of compounds The level of aliphatic hydrocarbons found, was due mainly to n-alkanes originated from weathering of terrestrial plants and algae production. It is also possible to observe the dilution effect of the lagoon about analyzed compounds, comparing the results obtained from different sampling points. In general, the sediments sampled in the investigated region presented small levels of contamination by hydrocarbons.
