PPersistent organic pollutants (POPs) are widespread worldwide reaching polar regions. Among POPs dichlorodiphenyltrichloroethane (DDT) and their metabolites have been reported scarcely in the Antarctic environment. Here we report levels of p,p’-DDT, o,p’-DDT, p,p’-DDE o,p’-DDE air water samples collected during austral summer 2009. The found ranged from 0.25 to 4.26 pg m-3 atmospheric while 0.07 L-1.

Abstract The determination of total atmospheric deposition (bulk) is an essential tool to assess the state environmental contamination and consequent exposure population persistent organic pollutants (POPs) through intake contaminated food. Over past 20 years, international authorities European Union various pieces legislation have emphasised importance conducting monitoring studies on depositions better understand their impact environment human health without setting reference values. Despite absence such values, several countries, national laws, adopted limit values and/or guideline for fluxes some (dioxins, furans, polychlorinated biphenyls polycyclic aromatic hydrocarbons) inorganic (metals). aim this review both summarise present discuss different legislations by member states. Furthermore, a focus paper will be dedicated Italian legislation, where there currently no specific POPs in deposition. In any case, Italy, as National Institute Health (ISS) Regional Environmental Protection Agencies (ARPA), conducted numerous activities depositions, providing scientific community policymakers with data which establish

Abstract Antarctica has one of the most sensitive ecosystems to negative effects Persistent Organic Pollutants (POPs) on its biodiversity. This is because lower temperatures and persistence POPs that promote their accumulation or even biomagnification. However, impact vascular plants unknown. Moreover, fungal symbionts could modulate host cope with this stress factor. study investigates molecular ecophysiological responses Sub‐Antarctic Antarctic plant Colobanthus quitensis in different populations along a latitudinal gradient (53°‐ 67° S), emphasizing role endophytic fungi. The results show exposure C. generates oxidative alters performance. Nevertheless, association endophytes exposure, shows lipid peroxidation, higher proline content photosynthetic capacity, as well biomass survival percentage, compared absence endophytes. On other hand, antarctic population (67°S) fungi presents better modulating upon exposure. Endophytic would be more necessary for performance towards latitudes extreme conditions, contributing significantly general functional adaptation. We develop transcriptomics analyses n quitensis‐ from Peninsula population. observed tolerance through upregulated genes redox regulation based ascorbate scavenging mechanisms (peroxidases, MDAR, VTC4, CCS), transformation (monooxygenases) conjugation compounds metabolites (glutathione transferases, glycosyltransferases, S‐transferases), storage elimination conjugates (ABC transporters, C G family) contribute detoxification cell. work highlights contribution resistance situations environmental stress, especially conditions such antarctica exposed anthropogenic impact. implications these findings are relevant biosecurity last pristine bastions worldwide.

The threats posed by Persistent Organic Pollutants (POPs) impact food safety and, implication, security in the polar regions. POPs tend to persist environment and fatty tissues of animals, thereby constituting long-term contamination. Due cold climate geography these regions, they create a sink for pollutants, which travel from their source production accumulate chains, resulting health risks ecosystem, humans Arctic Antarctica. In this paper, we draw attention how can lead insecurity, negatively affecting due unsafe traditional foods. A narrative synthesis methodology was employed, systematically analyzing historical data, activities, research trends on POP contamination ecosystems. We also highlight resilience promoted governance, with focus issues became an international matter 1970s, three United Nations (UN) conventions: UN-Environment Stockholm Convention Pollutants, UN Minamata mercury, UN-ECE Long-range Transboundary Air Pollution.
