Microplastic Exposure for Pinnipeds (Pinnipedia): A Rapid Review

Ecologies, Год журнала: 2025, Номер 6(2), С. 26 - 26

Опубликована: Март 31, 2025

The widespread distribution of microplastics (MPs) is causing increasing concern among the scientific community and public. Marine mammals are considered indicators ecological health marine ecosystems, many species, suffering from numerous anthropogenic factors, have been granted protected status. Pinnipeds (Pinnipedia) susceptible to ingestion bioaccumulation MPs their environment, through direct consumption trophic chain transfer. This literature review describes MP exposure for representatives three pinniped families—true seals (Phocidae), eared (Otariidae), walruses (Odobenus)—and based on 26 studies. Data content was reported in scat 17 articles, gastrointestinal tract (GIT) 8 blubber 1 article. Plastic material detected 22 studies, with its overall occurrence varying 0 100% samples. In addition quantitative assessment content, one study provides data correlation between levels animal organisms pollution biomarkers such as phthalates porphyrins. contemporary experience studying pinnipeds discussed step-by-step, focusing on: (1) collection, (2) extraction, (3) identification methods. current collated information methods results studies concerning (Pinnipedia), which can serve a guide future researchers this area.

Microplastics in the Amur tiger's habitat: Occurrence, characteristics, and risk assessment

Journal of Hazardous Materials, Год журнала: 2025, Номер 493, С. 138380 - 138380

Опубликована: Апрель 23, 2025

Microplastics (MPs) are emerging environmental pollutants that pose a significant threat to wildlife within forest ecosystems. However, the quantity and types of MPs in habitats remain unclear. This study is first assess distribution Amur tiger habitat northeast China. Our results showed were detected soil, water, atmosphere, forage plants, ungulate top predator feces ecosystem, respectively. The average diameter all was 44.99 ± 34.80μm. predominant polymers found samples polyamide, polyvinyl chloride, polyurethane. Certain sample shared similar MP polymer type distributions, indicating potential links their sources transfer pathways. Consequently, these findings provide some new insights on pollution problem prompt us consider how control manage conservation.

Bottom-Feeders Eat Their Fiber: Ingestion of Anthropogenic Microdebris by Antarctic Deep-Sea Invertebrates Depends on Feeding Ecology

Environmental Science & Technology, Год журнала: 2024, Номер unknown

Опубликована: Ноя. 20, 2024

Anthropogenic debris has been documented in Antarctica for the past 40 years. Upon breakdown, large pieces become microdebris, which reaches seafloor through a variety of physical and biological processes. The Antarctic benthos, deeply reliant on sinking organic particles, is thus vulnerable to ingesting microdebris. By using benthic specimens sampled between 1986 2016 deposited collections, we provide first record microdebris Southern Ocean deep-sea invertebrates. Specimens from 15 species (n = 169 organisms) had their gut content examined, with 13 yielding shape fibers 85 fibers). highest ingestion percentages were recorded sea cucumbers Heterocucumis steineni (100%), Molpadia violacea (83%) Scotoplanes globosa (75%), brittle star Amphioplus peregrinator (53%). Deposit- suspension-feeding strategies yielded most fibers, accounting 83.53% particles. Seven identified as microplastics, composed polyamide, polycarbonate, polyester, polyethylene terephthalate, polyisoprene polysulfone. We also earliest microplastic Antarctica, polysulfone fiber ingested by Boreomysis sp. mysid caught 1986. occurrence world's remote continental margin renews concerns pollution seemingly isolated regions.
