In birds, maternal transfer is a major exposure route for several contaminants, including poly- and perfluoroalkyl substances (PFAS). Little known, however, about the extent of different PFAS compounds to eggs, especially alternative fluorinated compounds. present study, we measured legacy emerging PFAS, Gen-X, ADONA, F-53B, in plasma prelaying black-legged kittiwake females breeding Svalbard yolk their eggs. We aimed (1) describe contaminant levels patterns both (2) investigate transfer, that is, biological variables relationship between eggs each compound. Contamination were dominated by linPFOS then PFUnA or PFTriA. notably found 7:3 fluorotelomer carboxylic acid─a precursor long-chain carboxylates─in 84% egg yolks, provide first documented finding ADONA wildlife. Emerging all below detection limit female plasma. There was linear association most PFAS. Analyses ratios suggest increasing with carbon chain length, therefore longest acids (PFCAs) preferentially transferred The mean ∑PFAS second-laid 73% first-laid Additional effort on assessing outcome transfers avian development physiology essential, PFCAs which are under-represented experimental studies.

Per- and polyfluoroalkyl substances (PFAS) concentrations were investigated in hepatic tissue of four dolphin species stranded along the south-east coast Australia between 2006 2021; Burrunan (Tursiops australis), common bottlenose truncatus), Indo-Pacific aduncus), short-beaked (Delphinus delphis). Two populations represented dataset have highest reported global population ∑25PFAS (Port Phillip Bay median 9750 ng/g ww, n = 3, Gippsland Lakes 3560 8), which 50–100 times higher than other here; (50 9), (80 1), (61 12). Also included results is individual (19,500 ww) PFOS (18,700 concentrations, at almost 30 % any Cetacea globally. Perfluorooctane sulfonate (PFOS) was above method reporting limits for all samples (range; 5.3–18,700 ww), constituted contribution to overall ∑PFAS burdens with 47 99 profile across dataset.

Per- and polyfluoroalkyl substances (PFAS) are persistent contaminants with documented harmful health effects. Despite increasing research, little attention has been given to studying PFAS contamination in low- middle-income countries, including Samoa. Using data biosamples collected through the Foafoaga o le Ola ("Beginning of Life") Study, which recruited a sample mothers infants from Samoa, we conducted an exploratory study describe concentrations 40 analytes infant cord blood at birth (n = 66) dried spots (DBS) 4 months post-birth 50). Of tested, 19 were detected blood, 10 >50% samples (PFBA, PFPeA, PFOA, PFNA, PFDA, PFUnA, PFTrDA, PFHxS, PFOS, 9Cl-PF3ONS); 12 DBS, 3 PFOS). generally lower than those reported existing literature, exception was higher concentrations.

The use of vibrational spectroscopy and supervised machine learning for chemical identification of plastics ingested by seabirds

Journal of Hazardous Materials, Год журнала: 2024, Номер 476, С. 134996 - 134996

Plastic pollution is now ubiquitous in the environment and represents a growing threat to wildlife, who can mistake plastic for food ingest it. Tackling this problem requires reliable, consistent methods monitoring ingested by seabirds other marine fauna, including identifying different types of plastic. This study presents robust method rapid, reliable chemical characterisation plastics 1-50 mm size range using infrared Raman spectroscopy. We analysed 246 objects Flesh-footed Shearwaters (Ardenna carneipes) from Lord Howe Island, Australia, compared data yielded each technique: 92 % visually identified as were confirmed spectroscopy, 98 those low density polymers such polyethylene, polypropylene, or their copolymers. Ingested exhibit significant spectral evidence biological contamination reports, which hinders identification conventional library searching. Machine learning be used identify vibrational spectra with up 93 accuracy. Overall, we find that more effective technique range, appropriately trained machine models superior searching plastics.

Implications of plastic ingestion on the growth and fledging success of shearwaters

Ingestion of plastic can have negative health consequences for wildlife. However, our understanding the physiological impacts plastics is limited, often relying on opportunistic sampling. We partnered with Tasmanian Aboriginal seabird harvesters, wildlife rescue clinics, and parks managers, to collect >400 fledgling yula/short-tailed flesh-footed shearwaters across a spectrum body conditions. explored blood chemistry, trace elements, broadscale growth metrics as proxy in relation ingested plastic. found beached yula fledglings were smaller (wing cord mass) than other groups. no significant relationships detected between ingestion any parameter. Critically evaluated, findings are comparable exposure data from similar (petrel shearwater) studies globally. These results suggest that most same-size petrels shearwater populations worldwide probably below threshold where sub-lethal be expected, which we posit occurs when loads exceed 1-3 % mass. indicate need quantify dose-risk responses seabirds, more generally.

While the problem of plastic ingestion by wildlife is well recognised, it also suffers from a "file drawer" where small incidentally collected data remains unpublished because on its own, may represent only handful individuals. There great strength, however, in combining these disparate datasets to make inferences about broader patterns and therefore inform discussion impacts extent providing for sparsely sampled taxa. Here we summarise records seven seabird species Western Australia New South Wales, provide baseline updates exposure plastics. For most included our assessment, this first available regarding more than two decades. Very low rates were observed Great-winged Petrels Pterodroma macroptera, Little Shearwaters Puffinus assimilis, Providence solandri with adult fledgling Wedge-tailed Shearwater Ardenna pacifica Sable carneipes containing moderate amounts (>8 % prevalence). Black-winged nigripennis Masked Boobies Sula dactylatra did not contain any ingested plastic. These reported using standardised methods ensure information can be used as benchmark against prior future studies. Syntheses such valuable knowledge regions or limited data, doing so, begin reveal pollution relevance conservation.

Understanding plastics’ harmful impacts on wildlife would benefit from the application of hypothesis agnostic testing commonly used in medical research to detect declines population health. Adopting a data-driven, proteomic approach, we assessed changes 745 proteins free-living nonmodel organism with differing levels plastic exposure. Seabird chicks heavily affected by ingestion demonstrated range negative health consequences: Intracellular components that should not be found blood were frequently detected, indicative cell lysis. Secreted less abundant, indicating stomach, liver, and kidneys are functioning as normal. Alarmingly, these signatures included evidence neurodegeneration <90-day-old seabird high ingested plastic. The reflect effects distal site exposure (i.e., stomach). Notably, metrics assess condition (such body mass) do provide an accurate description or ingestion.

Seabirds ingest contaminants linked to their prey's tissues, but also adsorbed ingested plastic debris. To explore relationships between plastics and trace elements concentrations, we analyzed 25 essential non-essential in liver tissue relation content the gastrointestinal tract adults of four species Arctic seabirds with different propensity plastic. Linear Discriminant Analysis (LDA) provided a clear separation based on element not among individuals without plastics. Molybdenum, copper, vanadium, zinc were strong drivers LDA, separating northern fulmars (Fulmarus glacialis) from other (60.4 % explained between-group variance). Selenium, zinc, mercury black-legged kittiwakes (Rissa tridactyla) (19.3 This study suggests that ingestion particles has little influence burden seabird species.
