dc.description.abstract | 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 Protection
Agency’s (EPA) priority pollutant list were analysed using gas chromatography–mass spectrometry (GC–MS). Surface water
sampling was undertaken in Todos os Santos Bay, northern Brazil. Total PAH concentrations varied from 0.0029 to 0.1079
ng/L in surface waters (main rivers, tributaries, etc.) with mean value of 0.0344 ng/L. Such concentrations can be taken as
background values for the studied region and show that PAHs are within or lower than levels reported in certain other areas.
The PAH profiles were dominated by high molecular weight PAHs (four- and five-ring components) in surface water samples.
It indicated that PAHs in surface water have its origin from oil or sewage contamination (petrogenic input). The collected
data, based on indices among phenanthrene versus anthracene, showed that petrogenic input was predominant at
almost all the stations investigated. Principal component analysis (PCA), using a correlation matrix, revealed the latent relationships
among all the surface water stations investigated and confirmed our analytical results. | pt_BR |
