“…While PA is also often used in automotive, transportation and textile industries and packaging (Queiroz et al, 2022). Its prevalence in finless porpoises may be attributed to its widespread use in aquaculture practices (Do et al, 2022), such as in fishing gear and ropes, as fishing is a main economic activity in this area. And PET is also commonly used in the production of clothing and textiles, or plastic packaging and containers (Lusher et al, 2017;Borges-Ramıŕez et al, 2020;Wang et al, 2021b).…”

Microplastics (MPs) pose serious threats to various marine organisms, including many threatened apex predators such as cetaceans. However, information on microplastic contamination in cetaceans from Asian waters is limited. Based on the analysis of Fourier transform infrared spectroscopy (FTIR), we reported MPs from finless porpoise intestinal samples and from their habitats along the Fujian coast of the East China Sea. MPs proved to be ubiquitous in both intestinal and habitat water samples. Most intestinal MPs were fibers (86.90%), transparent (51.19%), small sizes (<1.0 mm, 77.38%), and composed of polyamide (41.67%) or polyethylene terephthalate (45.24%). Seawater MPs were predominantly fibers (90.25%), transparent (82.45%), < 1.0 mm (83.76%) and composed of polypropylene (67.32%). Concentrations of MPs in coastal waters were greater than those in offshore waters. The concentration and composition of fibrous MPs indicate a likely textile industry origin. A recommendation is made to further assess the risks of MPs consumption in threatened species and develop scientific protection and management strategies.

“…The occurrence of MPs in several other seafoods like seaweed nori ( Li et al, 2020 ), stuffed mussels ( Gündoğdu et al, 2021 ), and oysters ( Do et al, 2022 ) might be a warning of the potential health risks associated with the long-term exposure to seafood derived MPs sources. In addition, the identification of processed seafood products as a potential route of MPs exposure, including the results found in this study, suggests that the extent of the problem is even greater.…”

The presence of microplastics (MPs) in processed seafood is a growing concern. In this study, 33 different canned fish brands belonging to seven producers were purchased from the Turkish market and investigated. MPs composition, possible sources, and potential intake were assessed. Light microscopy was used to quantify potential MPs, and micro-Raman microscopy was used to identify the polymer types. The results showed that all the samples had at least one MPs particle, and fragments were the most abundant (57.3%) shape of MPs. Polyolefin (21.88%) was the most common polymer type. The results showed that packaging and the production processes are the main possible sources of MPs. Human intake estimation risk is relatively lower since canned fish consumption is relatively low. The findings suggest that the risk related to MPs in canned fish should be considered one of the components of food safety management systems.

“…Similarly, to other transitional environments, these two Italian lagoons face a growing threat: MP accumulation. Bivalves like oysters filter feed at the water’s surface, making them susceptible to ingesting MPs [ 15 , 21 , 22 ]. This is why they are valuable bioindicators, allowing the assessment of MP contamination levels by measuring their accumulation in oyster tissues [ 21 , 22 , 23 ].…”

While the risks of human consumption of these MP-accumulating oysters are still under investigation [ 24 ], this study, alongside that of Provenza et al [ 25 ], aims to bridge that knowledge gap.…”

Microplastic pollution poses an escalating concern, particularly in coastal lagoons rich in biodiversity. This study delved into the occurrence of microplastics (MPs) in Magallana gigas (formerly Crassostrea gigas) from the Orbetello and Varano coastal lagoons (Italy), also investigating the response of these filter-feeding organisms to various colors (P = pink; B = blue; W = white) of high-density polyethylene (HDPE) MP fragments. Oysters were exposed for 7 days under controlled conditions. Subsequently, the oysters underwent analysis for both MP presence and biochemical markers of oxidative stress. Diverse ingestion rates of HDPE were noted among oysters from the two lagoons, eliciting antioxidant responses and modifying baseline activity. The two-way ANOVA revealed the significant effects of treatment (control; HDPE_B; HDPE_P; HDPE_W), site, and the interaction between treatment and site on all biomarkers. Non-metric multidimensional scaling showed a divergent effect of HDPE color on biomarkers. Further investigation is warranted to elucidate the mechanisms underlying the influence of MP color, dose-dependent effects, and the long-term impacts of exposure. Comprehending these intricacies is imperative for devising effective strategies to mitigate plastic pollution and safeguard marine health.
