Occurrence of persistent organic pollutants and polycyclic aromatic hydrocarbons in sediments of the inner bay of Lake Titicaca (Puno, Peru)

Descripción del Articulo

Lake Titicaca is an important water resource and the ecological balance of the Peruvian-Bolivian Andean plateau depends on it. At present, it is being disturbed by poor water resource management practices, which is why persistent organic pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs)...

At present, it is being disturbed by poor water resource management practices, which is why persistent organic pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs) were monitored in sediments from 13 sampling stations in the Inner Bay of Lake Titicaca (Puno, Peru). The samples were lyophilized and stored at -70°C for further analysis. For the validation of the analytical method, the following parameters were considered: recovery, repetition and uncertainty of all the compounds studied. The POPs were determined by gas chromatography coupled to an electron capture detector, and the presence of β-BHC, 0.018 μg/g; o,p´-DDE, 0.0011 μg/g; dicofol 0.0065 μg/g and endosulfan sulfate 0.0061 μg/g were detected. On the other hand, PAHs were determined by liquid chromatography coupled to a fluorescence detector, confirming the presence of naphthalene, 0.058 μg/g; pyrene, 0.039 μg/g; benzo(a)anthracene, 0.571 μg/g and chrysene, 0.033 μg/g. The presence of POPs and PAHs evidences an environmental risk for the species that inhabit the ecosystem of this lake.El lago Titicaca es un importante recurso hídrico y de él depende el equilibrio ecológico de la meseta andina peruano-boliviana. En la actualidad, está siendo perturbada por las malas prácticas de gestión de los recursos hídricos, razón por la cual los contaminantes orgánicos persistentes (COP) y los hidrocarburos aromáticos policíclicos (HAP) fueron monitoreados en los sedimentos de 13 estaciones de muestreo en el interior de la bahía del Lago Titicaca (Puno, Perú). Las muestras fueron liofilizadas y almacenadas a -70°C para su posterior análisis. Para la validación del método analítico se consideraron los siguientes parámetros: recuperación, repetición e incertidumbre de todos los compuestos estudiados. Los COPs fueron determinados por cromatografía de gases acoplada a un detector de captura de electrones, y se detectó la presencia de β-BHC, 0.018 μg/g; o,p´-DDE, 0.0011 μg/g; dicofol 0.0065 μg/g y sulfato de endosulfán 0.0061 μg/g.
