dc.description.abstract | Elemental analysis and isotopic composition
evaluated the impact of human activity at the
surface sediments in the largest island of Todos os
Santos Bay, northeastern Brazil. Saturated hydrocarbons
(n-alkanes and isoprenoids) by gas chromatography
coupled with a flame ionization detector and 13C
by mass spectrometer were determined from 30 surface
sediment samples in mangroves at the Itaparica
Island (Bahia-Brazil) in the rainy and dry season.
These data, distribution, and ratio of carbon/nitrogen
showed a mixture of sources: continental, marine, and
anthropogenic ones. From the chromatographic profiles,
light oil contamination was observed in the dry
regions of Baiacu, Campinas, and Ponta Grossa, while
in Jiribatuba it was observed during the rainy season.
However, δ13C results during dry and rainy season in
the presence of oil also showed in Misericordia and
Cacha Prego districts for both periods and Ponta
Grossa during the rainy season. Principal component
analysis, using a correlation matrix, revealed the latent
relationships among all the surface sediment stations
investigated and confirmed our analytical results. | pt_BR |
