“…16,17 A few reports on POPs in various Antarctic benthic species exist, for instance around Dumont d'Urville station (Adelie Land), 18 Davis station (Princess Elizabeth Land), 19 and Zucchelli station (Terra Nova Bay). 20 Unfortunately, the contribution of invertebrate samples to these studies was small, the proximity to the research stations as a potential contamination source was not always taken into account, and all of these studies were conducted in Eastern Antarctica. 21 Because the Western Antarctic Peninsula (WAP) has experienced some of the fastest rates of climate change, the composition and abundance of species in benthic ecosystems are likely to alter.…”

Pollutant levels in polar regions are gaining progressively more attention from the scientific community. This is especially so for pollutants that persist in the environment and can reach polar latitudes via a wide range of routes, such as some persistent organic pollutants (POPs). In this study, samples of Antarctic marine benthic organisms were analyzed for legacy and emerging POPs (polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and organochlorine pesticides) to comprehensively assess their current POP concentrations and infer the potential sources of the pollutants. Specimens of five benthic invertebrate species were collected at two distinct locations near Rothera research station on the Antarctic Peninsula (67°35′8 ̋ S and 68°7′59 ̋ W). Any impact of the nearby Rothera station as a local source of pollution appeared to be negligible. The most abundant chemicals detected were hexachlorobenzene (HCB) and BDE-209. The highest concentrations detected were in limpets and sea urchins, followed by sea stars, ascidians, and sea cucumbers. The relative congener patterns of PCBs and PBDEs were similar in all of the species. Some chemicals (e.g., heptachlor, oxychlordane, and mirex) were detected in the Antarctic invertebrates for the first time. Statistical analyses revealed that the distribution of the POPs was not only driven by the feeding traits of the species but also by the physicochemical properties of the specific compounds.

“…Zucchelli station showed an increase of the extractable fraction from the beginning of the summer, with maxima in the central period of the season, when human activity in the station is highest (Truzzi et al, 2017). As to organic compounds, the concentrations of some Persistent Organic Pollutants (POP) in the benthic Antarctic scallop Adamussium colbecki were attributed to local sources, such as ship traffic and fuel combustion processes near the research station facilities (Grotti et al, 2016). Anthropogenic volatile organic compounds, e.g.…”

“…Indeed, in some specific areas increasing amounts of metals, pesticides and other pollutants have been detected and attributed to both the local research stations and tourism presence as well as to the transportation of pollutants from other continents (e.g. Bargagli, 2008;Grotti et al, 2016;Magi and Tanwar, 2014;Truzzi et al, 2017). Terra Nova Bay is an area located between Cape Washington and the Drygalski Ice Tongue, along the coast of Victoria Land (Peña Cantero et al, 2013) and is classified among Antarctic Specially Protected Areas (ASPAs).…”

“…In order to protect the coastal ecosystems and human health from the increasing level of POPs, marine organisms e.g. mollusks (Sericano et al, 2014;Grotti et al, 2016), fish (Nyberg et al, 2015;Cincinelli et al, 2016), sea birds (Elliott and Elliott, 2013;Miller et al, 2015) and mammals (Lam et al, 2016) have been used as biomarkers to trace temporal trends of POPs (Table 2). Monitoring programs such as "Mussel Watch" of the US from 1986, "Swedish National Monitoring Program for Contaminants in Marine Biota" from 1969 and "Environmental Specimen Bank" initiated by Germany from the 1980s have conducted long term observations for coastal environmental changes (Sericano et al, 2014;Nyberg et al, 2015;Grotti et al, 2016).…”

<p>Coastal zone is of great importance in the provision of various valuable ecosystem services. However, it is also sensitive and vulnerable to environmental changes due to high human populations and interactions between the land and ocean. Major threats of pollution from over enrichment of nutrients, increasing metals and persistent organic pollutants (POPs), and climate change have led to severe ecological degradation in the coastal zone, while few studies have focused on the combined impacts of pollution and climate change on the coastal ecosystems at the global level. A global overview of nutrients, metals, POPs, and major environmental changes due to climate change and their impacts on coastal ecosystems was carried out in this study. Coasts of the Eastern Atlantic and Western Pacific were hotspots of concentrations of several pollutants, and mostly affected by warming climate. These hotspots shared the same features of large populations, heavy industry and (semi-) closed sea. Estimation of coastal ocean capital, integrated management of land-ocean interaction in the coastal zone, enhancement of integrated global observation system, and coastal ecosystem-based management can play effective roles in promoting sustainable management of coastal marine ecosystems. Enhanced management from the perspective of mitigating pollution and climate change was proposed.</p>
