Persistent organic pollutants (POPs) migrate from tropical and subtropical latitudes towards the poles due to their semivolatility, described by the global fractionation and condensation theory[1].

Abstract
Persistent organic pollutants (POPs) migrate from tropical and subtropical latitudes towards the poles due to their semivolatility, described by the global fractionation and condensation theory[1]. Many studies prove that Poles areas can be described as cold traps for pollutants with low volatility as POPs [2]. Snow is the most important scavenging agent of both vapor and particle-adsorbed POPs from atmosphere especially at high altitudes and latitudes. As a consequence, snow plays a key role in contaminant fate in the environment[3]–[5]. Activated carbon fibers (ACFs) are a class of promising microporous materials, which are considered one of the best adsorbents in adsorption application [6]. The ACF adsorbent was tested to be used for quantitative extraction of dioxin like-PCBs and pesticides from ice/snow, performing laboratory tests to asses all the procedures and real samples in Svalbard region to consider the matrix effect. In this study, the validation of this SPE method is presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
