Monitoring Emerging Contaminants in Antarctic seawater: past, present and future challenges
The investigation on the presence of contaminants in Antarctica has been included in several research projects within the Italian National Antarctic Research Program (PNRA). The impact of the research station activities, as well as long-range atmospheric transport, can cause classical and emerging c...

The investigation on the presence of contaminants in Antarctica has been included in several research projects within the Italian National Antarctic Research Program (PNRA). The impact of the research station activities, as well as long-range atmospheric transport, can cause classical and emerging contaminants (ECs) to be found in Antarctic seawater [1].

Two powerful approaches to overcome this problem are biomonitoring and passive sampling. Marine organisms can accumulate pollutants during their lives, sadly representing a sort of natural “long-term” passive sampler.
