Los contaminantes emergentes son sustancias químicas o materiales que se han detectado recientemente en las aguas y cuya presencia puede suponer un riesgo para el medio ambiente y la salud humana. Son compuestos que, hasta la actualidad no se habían podido determinar, aunque se usaran en todo tipo de aplicaciones, debido a la falta de métodos analíticos adecuados que detectaran concentraciones tan bajas. A pesar de ser compuestos que no están sometidos a ninguna regulación específica que limite su presencia en el agua, en un futuro podrían estar regulados si se determina que supone un riesgo para el medio ambiente. Por esta razón, es importante idear técnicas de análisis sensibles y selectivas para la detección y cuantificación de estos contaminantes en los ecosistemas acuáticos. Este Trabajo Fin de Grado se centra en el estudio de uno de estos contaminantes emergentes, la cocaína, así como su principal metabolito, la benzoilecgonina. Se recogen los diferentes tipos de muestreo, tratamiento de muestra y métodos de análisis para la determinación de dichas sustancias en aguas superficiales a nivel mundial.
Emerging pollutants are chemical substances or materials that have been recently detected in water and whose presence may pose a risk to the environment and human health. These compounds, despite being widely used in all types of applications, have not been able to be determined until now due to the lack of adequate analytical methods that detect such low concentrations. Although these compounds are not subject to any specific regulations limiting their presence in water, they may be regulated in the future if they are determined to pose a risk to the environment. For this reason, it is important to develop sensitive and selective analytical techniques for the detection and quantification of these pollutants in aquatic ecosystems. This Final Degree Project focuses on the study of one of these emerging pollutants, cocaine, as well as its main metabolite, benzoylecgonine. The different types of sampling, sample treatment, and analytical methods for the determination of these substances in surface waters worldwide are discussed.
