Priority contaminants in rainbow trouts (Oncorhynchus mykiss) from the township of mutiscua, Norte de Santander, Colombia

Contaminantes prioritarios en truchas arcoiris (oncorhynchus mykiss) del municipio de mutiscua, norte de santander, colombia

Polycyclic Aromatic Hydrocarbons (PAHs) are important compounds in determining atmospheric pollution produced by combustion from mobile sources, industrial pollution and oil industry. PAHs are considered priority pollutants by the US Environmental Protection Agency US (USEPA), due to its carcinogenic and mutagenic properties. PAHs in food, represent a potential risk to consumers, are easily associated with the particulate matter and finally settle into the sediment and water. In aquatic ecosystems PAHs join the biota of the environment and the fish are excellent biomarkers of his presence. Mutiscua region is influenced by atmospheric pollution from mobile to petrol and diesel driven on a nearby national road to the municipality. The growing interest today in research in the field of organic compounds such as Priority Pollutants (PP), is due to the identification of adverse effects of these pollutants on health and ecosystems. This research is an assessment of the presence of PP in muscle and skin of rainbow trout. The determination of PAHs (PP) was performed by gas chromatography using FID (FlameIonization Detector). It was possible to identify the presence of a mixture of Benzofluorantenos considered as possible carcinogenic to humans, and trace level the possible presence of Benzo(a) pyrene, also classified as a carcinogen.
