Micro- and Mesoplastic Consumption Tendency of Exaiptasia diaphana Sea Anemones

Animals, Journal Year: 2025, Volume and Issue: 15(3), P. 405 - 405

Published: Feb. 1, 2025

Microplastics are an increasingly common threat to the aquatic environment, and, due their small size, it is easy for them spread and enter seas oceans. Micro- mesoplastic particles often ingested by marine organisms, especially those that have potential successful settlement on artificial substrata, including plastic. In laboratory experiments, we tested tendency of sea anemone Exaiptasia diaphana consume plastic fragments fibers various sizes shapes; these organisms widely distributed in coastal waters, tide pools, coral reefs. The were placed either natural food or covered with a special gel form, which allowed retain original shape. Our studies shown shape less readily consumed than form fragments. E. anemones oral discs diameter 10–12 mm had difficulty consuming long fibers. A total 67% studied animals unable 13 length, while 3 7 length 100% anemones. We also established microplastics taken harmful cnidarians: mechanical injury body column was caused polypropylene microfragments, observed significantly increased mortality. Injuries, combined possible toxicological effects polymers, may been cause mortality diaphana.

Microplastic ingestion and Phthalate ester levels as plastic tracers in the Mediterranean Velella velella: a candidate plastic indicator for the pelagic neustonic environment

Marine Pollution Bulletin, Journal Year: 2025, Volume and Issue: 217, P. 118133 - 118133

Published: May 14, 2025

Bioindicator species can help assess plastic pollution's impact on biodiversity by integrating spatial distribution and temporal trends, highlighting associated ecological risks. To investigate a potential indicator for pelagic neustonic environments, the holoplanktonic hydrozoan V. velella was collected in Pelagos Sanctuary (SPAMI, NW Mediterranean Sea). A total of 460 individuals from 27 stations were alongside manta net trawls. Isolated organisms digested through an alkaline solution examined presence microplastics (MPs). The correlation among abundance floating area, microplastic ingestion levels 11 Phthalate Acid Esters (PAEs) have been investigated to provide comprehensive assessment multiple stressors impacting this species. Over 200 MPs isolated, with occurrence 93 % sampling (0.6 ± 0.7 items/individual). Polyester filamentous-shape particles (including fibres filaments; 81 %) polyamide, polyolefin polystyrene fragments (17 predominant particle types. PAEs concentration averaged 313 66 ng/g w.w. Dibutyl-phthalate, Diisobutyl-phthalate, Diethylhexyl-phthalate, listed as reprotoxic EU regulation, comprising 95 compounds. Despite no statistical correlation, slightly positive trend between ingested load found shedding light direct release particles. With its wide distribution, key trophic role, ability capture smaller fractions (<300 μm) accumulate chemicals surrounding environment, emerges promising bioindicator pollution areas Sea other seas oceans worldwide.

Evolution strategies for collaborative governance of marine microplastic pollution from the industry-research integration perspective

Frontiers in Marine Science, Journal Year: 2024, Volume and Issue: 11

Published: Oct. 10, 2024

Introduction Marine microplastics, are widely distributed in the global marine environment, posing a challenging issue that requires joint efforts of stakeholders. Methods To effectively address microplastic pollution (MMP) governance and analyze dynamic changes willingness various participants under different scenarios, this paper meticulously constructs game theory framework encompassing polluting enterprises, research institutions, environmental organizations. Results (1) On political level, implementation continuous strong economic penalty mechanisms is an effective means to deter enterprises from evading MMP responsibilities. However, execution strategy highly depends on participation supervision Therefore, it essential assign more roles responsibilities organizations ensure thorough measures. (2) technical effectiveness directly determines functional status institutions decision-making system. Weaker entities tend make decisions following behavioral preferences dominant entities. Thus, deepening integration industry fully unleashing outcomes key path enhancing overall efficiency effectiveness. (3) high costs often become significant factor limiting enthusiasm all parties participate. when innovative cooperation models achieve cost sharing benefit sharing, significantly increases. It evident optimizing resource allocation, improving fund utilization, establishing diversified sustainable funding guarantee mechanism crucial for advancing in-depth progress governance. Discussion In summary, study not only provides profound theoretical insights into interaction relationships choices multiple stakeholders but also offers practical strategic recommendations constructing efficient collaborative
