Influencia de la degradación del Clorpirifos en la detección analítica utilizando biosensores: revisión del estado actual y aspectos futuros
El Clorpirifós (CP) es un pesticida ampliamente utilizado, que se relaciona a diversos daños en salud y que ha obtenido importancia, dado a su ubicuidad en todas las matrices ambientales, unido a la necesidad de un monitoreo oportuno para evaluar el estado y tasas de descarga al medioambiente. Por su parte, los factores ambientales favorecen la degradación de CP y disipación en el medio ambiente, pero, dificulta su trazabilidad ambiental y detección real en las diversas matrices ambientales. El uso de biosensores proporciona técnicas analíticas prometedoras para la detección de diversos compuestos de importancia ambiental como lo es el CP en la actualidad, pero se desconoce si la degradación natural de CP afectaría el correcto reconocimiento de CP por parte de los biosensores, influyendo en su uso como herramienta de trazabilidad de descarga de CP al medioambiente. El objetivo principal de esta revisión es abordar los recientes avances de biosensores para la detección de CP, sus desafíos en la detección en muestras reales asociados a la degradación de CP y los aspectos futuros asociados al monitoreo ambiental, trazabilidad y detección del CP, que constituye una amenaza importante para la salud humana.
