Abstract
In the present study, the levels of sixteen polycyclic aromatic hydrocarbons (PAH) were determined in superficial sediments collected during three sampling campaigns carried out on May 2005, 14 months after oil spill, on December 2005 and on April 2006, in six stations at the tidelands. The Pajal and Candamo from Tumaco’s Bay, impacted by an oil spill occurred in March 2004. During the period of study the mean values of total PAH showed a decreasing trend, from 190ng/g obtained for the first campaign to 76ng/g for the last, letting to infer a temporal contamination and the area was in auto depuration state by product of petrogenic contamination processes. Finally, the concentrations for each of the PAH were found below the levels of risk established by the Canadian Environmental Quality Standards.
