“…Interestingly, PFAS contributed more than OCs to the total pollutant burden of king penguins’ plasma, contrary to results in other Southern Hemisphere seabirds, where PFAS contamination is still low, particularly at high latitudes. − The PFAS profile was consistent with most other studies in seabird plasma, showing a strong contribution of L-PFOS, and of odd-numbered long-chain PFCAs. ,, King penguins remain within the limits of the Southern Ocean year-round, where they feed almost exclusively on myctophid fish . Our results thus suggest that myctophid fish might be largely contaminated by PFAS in the Southern Ocean, as recently shown in the northeast Atlantic Ocean . This urges direct investigation, given the pivotal role of myctophid fish in Southern Ocean food webs …”

In vertebrates, fasting is an intricate physiological process associated with strong metabolic changes, yet its effect on pollutant residue variation is poorly understood. Here, we quantified long-term changes in plasma concentrations of 20 organochlorine and 16 perfluoroalkyl pollutants in king penguins Aptenodytes patagonicus during the breeding and molting fasts, which are marked by low and high levels of protein catabolism, respectively, and by strong lipid use. The profile of measured pollutants in plasma was dominated by perfluorooctanesulfonic acid (PFOS, initial relative contribution of 60%). Initial total pollutant concentrations were similar in molting (3.3–5.7 ng g–1 ww) and breeding penguins (range of 4.2–7.3 ng g–1 wet weight, ww). Long-term fasting (25 days) for molting and breeding led, respectively, to a 1.8- and 2.2-fold increase in total plasma pollutant concentrations, although the rate and direction of change were compound-specific. Hexachlorbenzene (HCB) and PFOS concentrations increased in plasma (net mobilization) during both types of fasting, likely due to lipid use. Plasma perfluoroundecanoate (PFUnDA) and perfluorotridecanoate (PFTrDA) concentrations increased in breeders (net mobilization) but decreased in molting individuals (net excretion), suggesting a significant incorporation of these pollutants into feathers. This study is a key contribution to our understanding of pollutant variation in blood during long-term fasting in wildlife.

“…Te low cost and widespread use of these chemicals in the industrial, agricultural and health sectors have led to their continued use in many developing countries [2]. Studies have shown that residues of HOPs are still detectable worldwide [3][4][5][6]. Even today, there are still some HOPs being produced and used in China, which makes HOPs pollution a constant problem [7].…”

This study used gas chromatograph-mass spectrometer (GC-MS) to determine three kinds of halogenated organic pollutants (HOPs) in the edible muscles of nine fish species in the Laibin section of the Hongshui River of Xijiang River in the Pearl River system. The results showed that the sum of organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs) in fish muscle was 8.94∼43.32 ng/g ww, 1.22∼4.09 ng/g ww, and ND∼0.13 ng/g ww, respectively. Evaluation indicators include analysis of the composition of homologous compounds, residues in different diets and habitats, and estimated daily intake (EDI) calculations. The analysis of the composition characteristics of homologous compounds showed that endrin was the most dominant in OCPs; hexachlorobenzene was the most dominant in PCBs; and BDE 154 was the most dominant PBDEs. Calculations of the levels of the HOPs in fish of different diets and habitats showed that OCPs and PCBs had the highest residues in carnivorous fish, and PBDEs had the highest residues in herbivorous fish. The residual OCPs, PCBs, and PBDEs in demersal fishes were the most. The estimated daily intake (EDI) results showed that daily fish consumption in the Laibin section of the Hongshui River would not cause HOPs health risks to the local residents. However, there is still a need for continuous monitoring of HOPs to reduce pollutant emissions and prevent pollution conditions from arising.
