Fish are visible members of aquatic communities that are vulnerable to contamination with polycyclic aromatic hydrocarbons (PAHs). Fish can have complicated life cycles and behavior. They can be exposed to PAH-contaminated sediments and water by a variety of routes, including respiration; ingestion of food, sediment, and detritus; and dermal absorption. This investigation involves a preliminary assessment of the sixteen PAHs issued by the United Stations Environmental Protection Agency (U.S. EPA) that were identified in entrails and muscles of fish affected by the oil exploitation in Shushufindi, Sucumbíos Province, Ecuador. The PAHs were extracted from the matrix, concentrated, purified by florisil column and analyzed using Gas Chromatography/Mass Spectrometry GC/MS. Three different sampling places were selected. Also, the collected fish were classified according their feeding behavior. Additionally, the contents of PAHs in the sediments to establish a relation between the contamination level in fishes and their feeding behavior were analyzed. This information and the knowledge about the food habits of the population in Shushufindi can show the possible contamination of the people from this zone.
