Deskripsi
Concentration and distribution of polycyclic aromatic hydrocarbons (PAHs) were determined in surface sediments at 34 stations of the eastern sector of the Gulf of Cariaco, Venezuela, in order to establish baseline in the ecosystem. The spatial distribution for total PAHs shows its highest concentrations to the west (between La Calentura and Marigüitar) and the gulf sack, presenting an average of 511.33 ng/g dry mass across the study area. 30% of the stations exceeded the effect threshold values suggesting a significant contribution of these compounds in the sediment.
