Por sus características físicas y químicas, es frecuente encontrarlos asociados a partículas, favoreciendo su permanencia en la atmósfera. En las últimas décadas, el monitoreo de hidrocarburos aromáticos policíclicos en ambientes urbanos se ha convertido en una prioridad debido a la gran cantidad de individuos expuestos. En este trabajo se evaluaron modificaciones de una metodología estándar para la extracción, detección y cuantificación de hidrocarburos aromáticos policíclicos adsorbidos en partículas de 2.5 µm de diámetro aerodinámico. Estas variaciones permitieron reducir considerablemente los tiempos y costos de procesamiento, la detección y cuantificación, sin disminuir la sensibilidad para la detección de estos compuestos. Por otro lado, la reducción considerable en la cantidad de disolvente utilizado resulta en una metodología más amigable con el ambiente.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT Polycyclic aromatic hydrocarbons are ubiquitous air pollutants, derived from the incomplete combustion of organic matter. Due to its physical and chemical characteristics, its association with the particulate matter is favored, and therefore its permanence in the atmosphere. In recent decades, the monitoring of polycyclic aromatic hydrocarbons in urban atmospheres has become a priority due to the high number of exposed individuals. In the present work, modifications of a standard methodology for the extraction, detection and quantification of polycyclic aromatic hydrocarbons were evaluated. These modifications resulted in reductions both in the extraction and quantification time, as well as in processing costs, which implies a substantial improvement in sample processing time, without reducing the sensitivity. In addition, the considerable reduction in the amount of solvent employed resulted in an environmentally friendly methodology.]]></p></abstract>
