Resumen:
Ushuaia is commonly regarded as the southernmost city in the world, is located in a wide bay on the southern coast of Isla Grande de Tierra del Fuego, bounded on the north by the Martial mountain range and on the south by the Beagle Channel. Ushuaia has developed on the coastal areas adjacent to Ushuaia and Golondrina Bays and currently has approximately 64.000 inhabitants. For 20 years, the entire coastal area has been receiving input from sewage, industrial and port, producing visible changes, some of them partially quantified. In particular is concerned generally poor and inadequate functioning of the sewage collection system and dispersant, located at the western end of the Ushuaia Peninsula, which has led to the discharge of untreated sewage along the coast. We study the drainage channels that cross the city, which receive the discharge of all types of wastewater. The samples were characterized by measuring physical and chemical parameters: dissolved oxygen, conductivity, salinity, turbidity, pH, temperature, total hydrocarbons, BOD, COD, soluble phosphorus, ammonia, nitrates, fat and oils, fecal and total coliforms, algal, cladocerans and fish acute toxicity, and chronic toxicity to Daphnia magna. Analytical determination of Pharmaceuticals and Personal Care Products compounds in surface water were performed by manual solid-phase microextraction with unbonded fibers of polydimethylsiloxane at a stationary phase of 100 and 7 ìm thickness and one of 85 ìm of polyacrylate that were injected into a GC-MS. The main substances determined were: Personal Care: Benzyl cyanide, Benzyl oleate, Tetramethyl octacosanol, Decylhydroxylamine, Acids: Myristic, Hexanoic, Decanoic decyl ester, Cyclopentaneundecanoic, Hexadecanoic methyl ester, Didecil ether, Naphthalenone, benzophenone, Ethanol Tetradecyloxy, Musklactone, Isopropyl Myristate, Octadecane, Ethanol dodecyloxy, Benzeneacetonitrile, Biphenyl Diethyl. Pharmaceutical: Di-Tert-Butyl Benzoquinone, Oleamide, Nandrolone, Acenaphthene, Urea, Oxabicyclo-Octane, Tetradecanoic Acid Methyl, Serinol, Oxonanone, Cyclohexanone, Dodecane chloro, Phenol dimethylethyl, Dodecanamine dimethyl, Indolizine. Others: Trichlorophenol, Diphenyl, Octamethylcyclotetrasiloxane, Trybutyl phosphate, Eicosanol, Ethanediol monoformate, Naphthalene Ethenyl, Aminoheptadecane. Many of the detected compounds are included as those with High Production Volume since their environmental impact could be relevant and should be assessed.
