In studies of plastic ingestion by marine wildlife, visual separation particles from gastrointestinal tracts or their dietary content can be challenging. Earlier have used solutions to dissolve organic materials leaving synthetic unaffected. However, insufficient tests been conducted ensure that different categories consumer products partly degraded in the environment and/or were not affected. this study 63 and 11 other items non-plastic debris tested. Irrespective shape preceding...
Summary In 2022, highly pathogenic avian influenza (HPAI) A(H5N1) virus clade 2.3.4.4b became enzootic and caused mass mortality in Sandwich Tern Thalasseus sandvicensis other seabird species across north-western Europe. We present data on the characteristics of spread between within breeding colonies number dead adult Terns recorded at sites throughout Within two months first reported mortalities, 20,531 were found dead, which is >17% total European population. This probably an...
Plastic pollution is of worldwide concern; however, increases in international commercial activity the Arctic are occurring without knowledge existing threat posed to local marine environment by plastic litter. Here, we quantify ingestion northern fulmars, Fulmarus glacialis, from Svalbard, at gateway future shipping routes high Arctic. Svalbard fulmars does not follow established decreasing trend away human impact. Of 40 sampled individuals, 35 (87.5 %) had their stomachs, averaging 0.08 g...
Marine plastic pollution is an environmental contaminant of significant concern. There a lack consistency in sample collection and processing that continues to impede meta-analyses large-scale comparisons across time space. This true for most taxa, including seabirds, which are the studied megafauna group with regards ingestion research. Consequently, it difficult evaluate impacts extent contamination seabirds fully accurately, make inferences about species we have little or no data. We...
One of the recently recognised stressors in Arctic ecosystems concerns plastic litter. In this study, juvenile polar cod (Boreogadus saida) were investigated for presence plastics their stomachs. Polar is considered a key species ecosystem. The fish collected both directly from underneath sea ice Eurasian Basin and open waters around Svalbard. We analysed stomachs 72 individuals under stereo microscope. Two contained non-fibrous microplastic particles. According to µFTIR analysis, particles...
Studies investigating the effects of plastic litter on marine biota have almost exclusively utilised pristine materials that are homogeneous in polymer type, size, shape and chemical composition. This is particularly case for microplastics (<5 mm), where collecting sufficient quantities from environment use laboratory impacts studies simply not feasible. Weathered plastics collected show considerable physical differences to post-production consumer plastics. For this study, macroplastic was...
This study combines published datasets with unpublished data on plastic ingestion in several North Sea fish species. The combined dataset of 4389 individuals from 15 species allows the analysis spatial distribution and temporal variability uptake fish. Airborne fibre contamination was observed to be main contributor fibres encountered samples. number samples strongly related time needed process a sample, not individual fishes sample. Accurate correction for secondary possible, but...
Abstract We collected data on mass mortality in Sandwich terns (Thalasseus sandvicensis) during the 2022 breeding season Netherlands. Mortality was associated with at least 2 variants of highly pathogenic avian influenza A(H5N1) virus clade 2.3.4.4b. report carcass removal efforts relative to survival colonies. Mitigation strategies urgently require structured research.
For this study, the transfer of plastic additives to stomach oil northern fulmars (Fulmarus glacialis) has been investigated. Procellariiform seabirds retain oily components their prey in theirs as a means store energy. A marine litter-derived microplastic reference mixture and separately polystyrene sample were added oils an experiment. total 15 additives, including plasticizers, antioxidants, UV stabilizers, flame retardants, preservatives identified original mixtures, monitored leachates....
Monitoring plastic in stomachs of beached northern fulmars for OSPAR's Ecological Quality Objectives (EcoQOs) has been incorporated into the European Marine Strategy Framework Directive (MSFD). This paper aims to provide appropriate tools interpret monitoring results. MSFD requires a data-derived threshold value (Fulmar-TV) representing 'Good Environmental Status'. Such Fulmar-TV was calculated from near-pristine Canadian Arctic data where 10.06% exceeded level 0.1 g ingested plastic. is...
Stomach contents of harbour porpoises (Phocoena phocoena) collected in the Netherlands between 2003 and 2013 were inspected for presence plastic other man-made litter. In 654 stomach samples frequency occurrence litter was 7% with less than 0.5% additional non-synthetic However, we show that when a dedicated standard protocol detection is followed, considerably higher percentage (15% 81 porpoise stomachs from period 2010–2013) contained Results thus strongly depended on methods used time...
Incidental studies of plastic ingestion by the northern fulmar (Fulmarus glacialis) over a wide geographical range can improve our understanding distribution marine litter in global oceans and processes involved. A sample 37 stomachs from fulmars collected June 2021 near Flemish Cap at eastern end Grand Banks Newfoundland was analysed for presence litter. Overall, 89 % birds contained plastic, with on average 6.6 particles, mass 0.093 g per bird. No statistical differences were found...
Although ingestion of plastic by tubenosed seabirds has been documented regularly, identification the polymer composition these plastics rarely described. Polymer assessment may assist in identifying sources and indicate risks from additives occurring specific types polymers. Using known test materials, two methods Fourier transform infrared spectroscopy near (FTIR NIR) were compared. both found to be similarly suitable for polymers, a significant difference was observed natural materials....
Concerns about the impact of plastics pollution on environment have been growing since 1970s. Marine debris has reportedly entangled and (or) ingested by 914 marine species ranging from microinvertebrates to large mammals. Shorebirds a high potential be exposed ingest pollution, as many migrate long distances periodically concentrate around shorelines, coastal areas, estuaries that can elevated levels pollution. Currently, little is understood exposure, frequency occurrence (FO), impacts...
Abstract A sample of 145 stomachs from fulmars hunted 100 km offshore east Greenland 64° 30′ N in early June 2015 was analysed for abundance plastic litter. Overall, 86% the contained plastics with an average 13.5 particles, and 0.14 g per stomach. proportion 42% exceeded level 0.1 plastic, whereas international policy target aims at a reduction to less than 10%. The observed quantity ingested fits pattern reduced higher latitudes, greater distance densely populated industrialised areas....
A bstract In 2022, highly pathogenic avian influenza (HPAI) A(H5N1) virus clade 2.3.4.4b became enzootic and caused mass mortality in Sandwich terns other seabird species across northwestern Europe. We present data on characteristics of the spread between breeding colonies number dead adult recorded at sites throughout Within two months after first mortalities were reported, total 20,531 found dead, which is >17% European population. Losses are likely higher, as we expect that many...
An analytical method was developed for the quantitation of mineral oil aromatic hydrocarbons in cosmetic raw materials separating those one or two rings from three and more rings. Normal phase high performance liquid chromatography used with donor-acceptor complex chromatography. The composition both fractions quantities respective compounds were determined by comprehensive dimensional gas time flight mass spectrometry coupled to flame ionization detection.
