“…MPs cannot be utilized as energy sources due to the lack of enzymes and enzymatic pathways for their breakdown. MPs ingested by oysters accumulate in the gills and digestive glands of the oysters and induce unfavorable effects in oysters, such as metabolic disorders [ 22 , 28 ].…”

“…The presence of esters can weaken the pungent taste of fatty acids and the bitter taste of amino groups [ 36 ]. According to He et al, the accumulation of esters was related to the increase in bacteria, such as Candida , Bacillus , and Aspergillus , and MPs could provide factitious niches for the colonization of microbes and improve their accumulation in oysters [ 28 , 37 ]. Therefore, it could be speculated that MP exposure caused the accumulation of microbes in oysters, improving the microbial decomposition of lipids and leading to the formation of esters.…”

“…The contents of Asp significantly decreased ( p < 0.05), while the level of glutamate increased after 1, 10, and 100 mg/L MP treatment compared with the control; however, no significant variance was observed in the total amounts of Glu and Asp. As the precursor of glutathione (GSH), an elevation in glutamate was related to the production of GSH because the toxicity of MPs mainly comes from oxidative stress via the overproduction of reactive oxygen species (ROS) [ 28 ], and GSH is an immensely important member of antioxidants, which plays a prominent part in the protective process against oxidative stress. The contents of glycine decreased after the MP treatment, and studies demonstrated that the glycine level is linked to the health status of oysters, observing a decrease in these amino acids after heavy metal and pathogen contamination [ 22 ].…”

“…The implementation of antioxidant defenses requires substantial extra energy. However, potential food shortage and MP retention in the digestive tract of C. gigas might increase satiety and disturb feeding behavior, which would lead to reductions in energy reserves; therefore, FAs might be used and reallocated to support defense mechanisms and individual maintenance under MP stress [ 15 , 28 ]. The analysis of the alteration of the FA profile allowed us to understand changes in FAs and identify potentially improved metabolic pathways [ 15 ].…”

Microplastics have been an emerging threat to filtering species and the ingestion and impacts of microplastics on oysters are a cause for concern. However, much remains unknown about the effects of microplastics on flavor-related biomarkers in oysters. Herein, a laboratory microplastic exposure with concentrations of 1, 10, and 100 mg/L for 15 days was performed to investigate the impacts of microplastics on the flavor parameters of oysters. Exposure to microplastics changed the odor characteristics of oysters. Microplastic exposure had minor effects on the fatty acid composition; however, significant alterations in free amino acids and nucleotides were observed under the 1 and 10 mg/L exposure groups, respectively. The overall results indicated 10 mg/L of microplastic exposure significantly increased the equivalent umami value of oysters. These findings stressed the effects of microplastics on oysters and would be an important reference for the assessment of the potential risks associated with microplastics in marine edible species.

“…Since the 1950s, our reliance on plastic has increased dramatically. Its low cost, durability, and resistance to degradation have led to its widespread use and, unfortunately, its release into the environment [ 6 , 14 , 15 ]. This plastic influx has significantly impacted marine ecosystems, and coastal lagoons are no exception [ 16 , 17 , 18 ].…”

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.
