“…However, based on the design of our model experiments and the responses of the biochemical markers, it is reasonable to assume that a chemical factor was the leading factor behind the pro-oxidant biochemical changes in both mollusk species. Furthermore, this view is based on multiple studies indicating that EPS contains several chemical components that are relatively easily and rapidly leached into the environment [ 13 , 18 , 26 , 27 , 59 , 60 , 61 ]. More than 40 low-molecular-weight chemicals were detected in EPS [ 27 ], as well as ethylbenzene [ 59 ], bisphenol A (BPA) [ 61 ], and toxic metals (Hg, Pb) [ 62 , 63 ].…”

“…Hexabromocyclododecane is the main chemical additive (0.7–2.5%) used for the fire safety of EPS products [ 61 ]. This brominated antiperene is not covalently bound to the polymer and thus can be easily released from EPS fragments into the environment.…”

Expanded polystyrene (EPS) is a major component of plastic debris in the environment, including coastal and littoral zones. EPS is widely used in various industries including fish farming and aquaculture, which poses a serious potential threat not only to cultured hydrobionts but also to all living organisms, including humans. This paper presents the results of experimental studies on the effects of EPS (0.024 m2/L) on marine mollusks Mytilus trossulus and Tegula rustica, which are typical inhabitants of the upper littoral of Peter the Great Bay (Sea of Japan), belonging to different systematic groups and differing in the type of nutrition. The results of biochemical marker analysis showed the development of oxidative stress processes. Thus, increasing malondialdehyde content relative to control values was registered in the digestive glands of M. trossulus and T. rustica. In the cells of the digestive glands of M. trossulus, integral antioxidant activity decreased more than 1.5 times compared with that of the control. The change in the concentration of protein carbonyls was unchanged in M. trossulus, whereas in T. rustica, there was a 1.5-fold increase. EPS exposure also resulted in significant DNA damage in the studied mollusks—the damage level increased 2.5-fold in M. trossulus and 1.5-fold in T. rustica relative to the control, indicating the genotoxic potential of EPS litters.

“…When investigating MPs in the environment, it is important to identify their characteristics, such as physical (shape, size, color, surface morphology) and chemical (polymer type) features, that are helpful for assessing their possible sources and degree of degradation. 45,[49][50][51][52] For that reason, in this study, different physical and chemical features including the shape, color, type, and surface morphology of the collected MPs were investigated.…”

“…Chemical additives are not chemically bound to polymers and may leach into the environment or organisms after ingestion, posing a potential risk (Hermabessiere et al, 2017; Ockenden et al, 2022; Thompson et al, 2009). For example, additives such as bisphenol A and brominated flame retardants, recognized as endocrine disruptors, have been shown to leach from MPs into the marine environment (Barhoumi et al, 2023). Several recent studies highlight the need for further investigation into the threat of chemical additives within the global plastic pollution (Burgos‐Aceves et al, 2021; Dong et al, 2017; Wang & Qian, 2021).…”

The presence and persistence of microplastics (MPs) in diverse aquatic environments are of global concern. Microplastics can impact marine organisms via direct physical interaction and the release of potentially harmful chemical additives incorporated into the plastic. These chemicals are physically bound to the plastic matrix and can leach out. The hazards associated with chemical additives to exposed organisms is not well characterized. We investigated the hazards of plastic additives leaching from plastic. We used the common plasticizer dibutyl phthalate (DBP) as a chemical additive proxy and the New Zealand green‐lipped mussel (Perna canaliculus) as a model. We used early‐adult P. canaliculus exposed to combinations of virgin and DBP‐spiked polyvinyl chloride (PVC), MPs, and DBP alone for 7 days. Whole transcriptome sequencing (RNA‐seq) was conducted to assess whether leaching of DBP from MPs poses a hazard. The differences between groups were evaluated using pairwise permutational multivariate analysis of variance (PERMANOVA), and all treatments were significantly different from controls. In addition, a significant difference was seen between DBP and PVC MP treatment. Transcriptome analysis revealed that mussels exposed to DBP alone had the most differentially expressed genes (914), followed by PVC MP + DBP (448), and PVC MP (250). Gene ontology functional analysis revealed that the most enriched pathway types were in cellular metabolism, immune response, and endocrine disruption. Microplastic treatments enriched numerous pathways related to cellular metabolism and immune response. The combined exposure of PVC MP + DBP appears to cause combined effects, suggesting that DBP is bioavailable to the exposed mussels in the PVC MP + DBP treatment. Our results support the hypothesis that chemical additives are potentially an important driver of MP toxicity. Environ Toxicol Chem 2024;00:1–11. © 2024 The Authors.
