Article
Temporal trend analysis of (total) mercury (THg) concentrations in Arctic biota were assessed as part of the 2021 Arctic Monitoring and Assessment Programme (AMAP) Mercury Assessment. A mixed model including an evaluation of non-linear trends was applied to 110 time series of THg concentrations from Arctic and Subarctic biota. Temporal trends were...

There has been a considerable number of reports on Hg concentrations in Arctic mammals since the last Arctic Monitoring and Assessment Programme (AMAP) effort to review biological effects of the exposure to mercury (Hg) in Arctic biota in 2010 and 2018. Here, we provide an update on the state of the knowledge of health risk associated with Hg conce...

Seafood has a great ecological and nutritional value for human and wildlife communities. However, accumulation of mercury (Hg) in fish is a concern to animal and human health. There is a crucial need to understand Hg speciation in marine organisms through controlled feeding experiments. This study represents a first assessment of the biological pro...
Article
Mercury (Hg) concentrations have significantly increased in oceans during the last century. This element accumulates in marine fauna and can reach toxic levels. Seafood consumption is the main pathway of methyl-mercury (MeHg) toxicity in humans. Here, we analyzed total Hg (T-Hg) concentrations in two oceanic squid species (Ommastrephes bartramii an...

Plastic debris is globally found around the world and the remote Arctic is no exception. Arctic true seals are sentinel species of marine pollution and represent the link between marine food webs and Arctic apex predators like polar bears and humans. With regard to true seals, ingested macroplastics have never been reported in an Arctic species. We...
Article
Hg accumulation in marine organisms depends strongly on in situ water or sediment biogeochemistry and levels of Hg pollution. To predict the rates of Hg exposure in human communities, it is important to understand Hg assimilation and processing within commercially harvested marine fish, like the European seabass Dicentrarchus labrax. Previously, va...

Humpback whales (Megaptera novaeangliae) from the Southern Hemisphere carry information on persistent organic pollutants (POPs) from their feeding zones in Antarctica to their breeding grounds, making this species a sentinel of contaminants accumulation in the Southern Ocean. This study aimed to evaluate driving factors, namely feeding areas, troph...
Article
In the Barents Sea, pelagic and coastal polar bears are facing various ecological challenges that may explain the difference in their pollutant levels. We measured polychlorinated biphenyls, organochlorine pesticides, polybrominated diphenyl ethers in fat, and perfluoroalkyl substances in plasma in pelagic and coastal adult female polar bears with...

In April 2017, we conducted a cruise in the Greenland Sea, on board of the RV “Helmer Hansen”. The main objective was to collect tissue samples of hooded seal (Cystophora cristata) pups, during the post-weaning fast. Four hooded seals (1 male, 3 females) were sampled. Hooded seals’ length ranged between 93 and 105 cm. We estimated the pups to be ±...

Mercury (Hg) in Arctic biota is increasing in contrast with trends in the rest of the world. In top predators, tissue levels surpassed the established toxicity thresholds. New research has revealed how the Arctic Hg cycle has altered because of sea-surface temperature increase and sea-ice cover decline. True seals are Arctic top predators. As such,...
Article
A recent Science report predicted the global killer whale population to collapse due to PCB pollution. Here we present empirical evidence, which supports and extends the reports’ statement. In 2016, a neonate male killer whale stranded on the German island of Sylt. Neonatal attributes indicated an age of at least 3 days. The stomach contained ∼20 m...

Ecological and physiological factors lead to different contamination patterns in individual marine mammals. The objective of the present study was to assess whether variations in contamination profiles are indicative of social structures of young male sperm whales as they might reflect a variation in feeding preferences and/or in utilized feeding g...

Study of the effect of species eology and distribution on T-Hg accumulation processes in Arctic trues seals with extreme physiologies.
Article
Rationale: Intrinsic biogeochemical markers, such as stable isotope ratios of carbon, nitrogen and sulphur are increasingly used to trace the trophic ecology of marine top predators. However, insufficient knowledge of fractionation processes in tissues continues to hamper the use of these markers. Methods: We performed a controlled feeding exper...

This is a preliminary study on the contaminaDon levels of both organic (PCBs and DDTS) and inorganic (mercury, cadmium, etc.) pollutants in several Dssues of sperm whales stranded along the coasts of Schleswig Holstein (Germany), during the mass stranding event occurred January 2016. We compared our results with the data presented by Holsbeek et al...

The blubber biopsy sampling technique allows sampling of skin and blubber from free-ranging whales and dolphins. In many studies, this technique complements samples obtained from stranded and by-caught individuals, which provide access to internal tissues including muscle, liver or kidney. These organs are essential to better assess biochemical pat...

The numerous anthropogenic activities occurring nowadays in the North-western Mediterranean Sea strongly affect top predators such as marine mammals, especially through the bioaccumulation of lipophilic contaminants. In order to assess the eco-toxicological status of local living cetaceans blubber biopsies were collected between 2006 and 2013. Sele...

The Association of Polar Early Career Scientists (APECS) is an international and interdisciplinary organization for undergraduate and graduate students, postdoctoral researchers, early faculty members, educators and others with interests in Polar Regions and the wider cryosphere. Find out more at the APECS website: https://www.apecs.is/ APECS Belgium, the Belgian National Committee of APECS, was founded by Ines Tavernier and Anton Van de Putte in 2011. APECS Belgium intends to create a network for early career scientists with different background aiming at creating awarness among the general public on polar research. We are very active on various social media channels (website, Facebook page and Twitter), we conduct outreach activities in schools and we participate in networking events among national and international collaborators. Every early career scientist based in Belgium with an interest in the polar regions is highly encouraged to join us! We also invite others with links to polar education and research to become a part of APECS Belgium.

Use of organic and inorganic contaminants to describe the resident populations of Mediterranean sperm whales, long-finned pilot whales and fin whales
Project
This project attempts to assess dynamics of Hg accumulation in highly specialised phocids through the integration of Hg species and isotopic signatures. Two species will be used as model: the hooded seal Cystophora cristata and harp seal Pagophilus groenlandicus. Specifically, we will assess two main questions: (1) how habitat use and prey choice influence Hg inputs and forms of entry in adults; and (2) how such Hg is mobilised and transferred during lactation and fasting. Through the innovative use of advanced data analysis tools this project will combine ecological tracers like stable isotopes of nitrogen (N), carbon (C) and sulphur (S), with pollution tracers such as Total-Hg (T-Hg), Hg species (MeHg vs. IHg), and Hg stable isotope composition (199Hg, 201Hg, 202Hg), to track and explain Hg sources and transformation processes outside and inside the organisms. This project will also permit to improve information about Hg cycling and accumulation in the Arctic environment, essential to understand future contamination trends and potential risks not only to local biota but also to humans; and validate, as it has been done already in fish, the use of Hg stable isotopes as tracers of Hg sources and characterisation, in highly physiologically specialised animals such as true seals.
