Summary: | 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. |
