Extracción de micropásticos en sedimentos

Abstract

La importancia de este estudio reside en que aporta herramientas para el estudio de la bioacumulación de microplásticos y otros contaminantes emergentes en la biota acuática. Se pondrán a punto dos métodos de extracción de microplásticos, uno para sedimentos del rio Turia y otro para mejillones expuestos. Se utilizan un método basado en la diferencia de densidad y flotabilidad de los plásticos y otro basado en una digestión de la materia orgánica mediante KOH y posterior observación en lupa en ambos casos. El trabajo también aborda el estudio de un método sencillo capaz de extraer contaminantes emergentes de mejillones expuestos mediante QuEChERS. Los contaminantes emergentes se cuantifican mediante HPLC acoplado a un espectrómetro de masa con detector de triple cuádruplo. Los resultados obtenidos muestran una buena extracción de los microplásticos en el caso de la digestión con KOH gracias a la eliminación del pie del mejillón. En sedimentos los resultados deberían mejorarse ya que se arrastra mucha muestra que impide su visualización. En cuanto a los contaminantes emergentes la extracción de las muestras expuestas da buenos resultados, aunque se debe intentar minimizar el efecto matriz para obtener una mejor cuantificación.
