Flamingos, with a lifespan of up to 50 years, are therefore likely to accumulate metals from the highly saline waters where they feed and breed. The concentrations of accumulated metals would be reflected in organs, feathers, and eggs. There are no data available on metals in flamingo egg contents. Concentrations of 24 elements in egg content and eggshells from Lesser Flamingo Pheoniconaias minor breeding at Kamfers Dam South Africa suggest metal pollution, but with considerable variation between eggs, reflecting their nonbreeding, nomadic movements. Strontium in eggshells exceeded toxic reference values. Copper in egg contents suggests reproductive stress. Lower than-expected metal concentrations (especially mercury) in egg contents we attributed to several excretory pathways prior to oogenesis and embryogenesis, thereby protecting the embryo. Molar concentrations of selenium and mercury were not correlated. However, the mean molar ratio of 8.2 suggests a highly protective effect afforded by selenium. Relative compositional differences show that eggshells are not a proxy for egg contents. We highlight previously unrecognised routes of post-hatching pollutant uptake via consumption of eggshells and parental crop milk. The post-hatching development of flamingo chicks may therefore be more susceptible to pollutant disruption compared with embryonic development. We conclude that P. minor eggs are not good indicators of environmental metal pollution, nor does it reflect post-hatching risks.

The historical profiles of these toxic metals coincide well with the recorded production of metal industry in the upper reach of the Krka River with a sharp decrease reflecting the interruption by the war and slow recovery afterwards. By contrast, the recovery of the tourist industry in Krka NP after the war was accompanied by increasing contamination by elements characteristic of boat and car traffic (Sn, Cu, Pb) as well as oil pollution. The contamination with polycyclic aromatic hydrocarbons and polychlorinated biphenyls was only moderate. Although levels of metallic and organic contamination can be considered relatively low, the observed shift from industrial to tourism-related sources indicated that touristic activities should also be regarded as a possible threat for this vulnerable karst aquatic ecosystem.</p></div>","PeriodicalId":8377,"journal":{"name":"Archives of Environmental Contamination and Toxicology","volume":"87 3","pages":"335 - 352"},"PeriodicalIF":3.7,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142399144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to identify the concentration and characteristics of MPs in hemolymph and organs (gills and hepatopancreas) of green mussels (<i>Perna viridis</i>) that are frequently consumed by people in Pangkajene Kepulauan, South Sulawesi Province, Indonesia. Green mussels were collected from two different sampling sites for comparison. Screening was carried out on dispensed hemolymph and dissected organs to identify the characteristics of MPs. Surface seawater sampling was added as information on MP's characteristics from the mussel habitat. Visual observation of MP's characteristics using a stereomicroscope in laminar flow is to prevent contamination. The identification of MP's polymer type is using FTIR-ATR. The results showed that hemolymph, hepatopancreas, gills, and surface water were concentrated with MPs. Small (2–3.9 cm) green mussels accumulated more MPs than medium (4–5.9 cm) and large (&gt; 6 cm). MPs characteristics of fiber shape, transparent color, and size 0.1–0.5 mm were dominant in all samples. A total of seven polymers of MPs were identified with polyethylene and polystyrene types most frequently found from all samples. Based on this study, green mussels are good for biomonitoring of MPs.</p></div>","PeriodicalId":8377,"journal":{"name":"Archives of Environmental Contamination and Toxicology","volume":"87 3","pages":"321 - 334"},"PeriodicalIF":3.7,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142387499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
