First Evidence of Microplastics in the Yolk and Embryos of Common Cuttlefish (Sepia officinalis) from the Central Adriatic Sea: Evaluation of Embryo and Hatchling Structural Integrity and Development

Animals, Journal Year: 2022, Volume and Issue: 13(1), P. 95 - 95

Published: Dec. 27, 2022

Once they reach the aquatic environment, microplastics (MPs) are accidentally ingested by biota, thus entering food chain with possible negative effects. The present study investigated, for first time, MP presence in cuttlefish (Sepia officinalis) eggs and their association embryonic development. Cuttlefish were sampled from four different sites along Marche region (Senigallia, Ancona, Numana, San Benedetto del Tronto). Embryo hatchling biometric parameters evaluated internal structural integrity was examined through histological analysis. MPs detected characterized embryos yolk samples. identified all (size < 5 µm), however, has not been associated an impairment of either embryo or structures. Noteworthy, highest number (in both samples) found Numana (37% total amount), where lowest size observed. On other hand, mantle length (9%) Ancona. Overall, only fragments sphere types (74 26%, respectively) observed, most frequent polymers Polyvinyl chloride (52%), Polypropylene, Cellulose acetate (15% both). Further studies needed to assess effects on quality assimilation.

Freshwater Fish Siberian Dace Ingest Microplastics in the Remote Yenisei Tributary

Toxics, Journal Year: 2022, Volume and Issue: 11(1), P. 38 - 38

Published: Dec. 30, 2022

This study analyzed microplastics in the gastrointestinal tract of Siberian dace (Leuciscus leuciscus subsp. baicalensis (Dybowski, 1874)) remote Yenisei tributary Nizhnyaya (Lower) Tunguska River (Siberia, Russia). µRaman analysis showed that 60% fish from two different sites had ingested plastic microparticles (on average, 1.55 ± 1.95 items per individual). The most common type microplastic were fibers, and abundant size category was 300 to 1000 µm. In studied population, no significant differences MP content between or males females found (p > 0.05). tendency for higher ingestion by at earlier ages (2+ 3+) compared later (4+ 5+) observed, which may be connected features biology ecology.

Pervasive Microplastic Ingestion by Commercial Fish Species from a Natural Lagoon Environment

Water, Journal Year: 2024, Volume and Issue: 16(20), P. 2909 - 2909

Published: Oct. 13, 2024

Microplastics have emerged as a significant global environmental concern in the recent decade. The aim of this study was to elucidate microplastic contamination commercial fish species natural lagoon environment. Microplastic examined gastrointestinal tracts and gills 157 from 18 with varying feeding habits vital sensitive ecosystem, which connects Indian ocean. were extracted using digestion, followed by stereomicroscopic inspection Nile Red stain, identified via μ-FTIR analysis. Over half studied fishes ingested microplastics (54.14%). Filaments (50%) blue items (43%) most commonly ingested. Of all species, Eubleekeria splendens had highest average concentration GIT (1.41 ± 2.52 items/g w.w. tissues), although no statistically difference amount (items/g tissues) observed among species. concentrations inhaled recorded Sillago vincenti (1.38 1.30 tissues). majority (33%) belonged size class 500–1500 μm rayon, polyethylene terephthalate, polypropylene primary polymers. This found correlation between ingestion habits, but positive observed. These findings reveal widespread edible fish, posing potential risks commercially important due increasing pollution ecosystems.
