“…According to Jeong et al, 2016 [70], for example, a toxicity study of uorescently labeled polystyrene microbeads with different sizes (0.05, 0.5, and 6 µm) on Monogonont Rotifer (Brachionus koreanus) showed increased GSH content after 12 h in a size-dependent manner. Contrary to this study, however, declined GSH content has been reported in larval zebra sh [51,71] and juvenile Eriocheir sinensis [52] exposed to MPs. Overall, there are diverging results concerning GSH content and evidence on the relationship between GSH content and oxidative stress are not su cient.…”

“…They explained this result by the sensitivity of exploited technique ( ow cytometery) and/or the sampling time chosen for its measurement. However, polystyrene microplastics in juvenile Eriocheir sinensis and larval zebra sh signi cantly alleviated the activity of CAT [51,52]. In contrast, in a study involving Mytilus galloprovincialis, Sendra [53] reported a decreased percentage of ROS as a result of exposure to different sizes of PS-NPs.…”

Background Few studies have examined nano-sized plastic particulates (NPs) exposure in relation to oxidative stress and biochemical responses in rodents, commonly used for toxicity evaluations on which to base risk assessment for humans.Methods Here we explored possible oxidative stress and biochemical responses of five weeks oral exposure to polystyrene (PS) nanoparticles (1, 3, 6 and 10 mg/kg body weight per day) in male rats. We used variance analysis and variance explained statistic eta-squared (𝜂2) to estimate the strength of relationships worked out. The whole body scanning further provided insight into the bio-distribution of nanoplastics upon oral exposure.Results Results demonstrated the accumulation of PS-NPs through whole body and also a dose-dependent increase in the production of reactive oxygen species (ROS). Significant alterations in antioxidant responses including serum levels of catalase, superoxide dismutase (SOD), and total glutathione content were noticed, pointing towards a perturbation of redox state induced by the exposure conditions. Acetylcholinesterase level in highest dose group was about 40 percent lower than those in control group. Biochemical parameters viz. glucose, cortisol, lipase, lactate, lactate dehydrogenase (LDH), alkaline phosphatase, gamma-glutamyl transpeptidase (GGT), triglycerides, and urea showed a significant increase, while total protein, albumin and globulin levels showed an appreciable decline.Conclusion The pattern of associations noticed with AChE activity and biochemical responses in our study suggests the possibility that a neurobehavioral effect or dysfunctions in energy metabolism, or both, may be the potential mode of action, possibly through stress response as well as liver function. Perturbations of creatinine and uric acid levels are indeed plausible biological explanations for the association with kidney dysfunction. Although we provided a new scientific clue for exploring the biological effects of plastics nanoparticles, the results warrant additional research with a larger sample size. The suggested potential mechanisms also remains to be investigated.

“…Laboratory based studies describe a wide range of effects of MPs on different taxa including effects on morphology and life history traits, such as reduction in food intake and somatic growth, increased mortality, behavior, or altered enzymatic activity 67–70,87–92. However, the lack of observed effects on measured parameters are also described 54,71,93,94.…”

Microplastics in Freshwater Biota: A Critical Review of Isolation, Characterization, and Assessment Methods

et al. 2019

View full text Add to dashboard Cite

Freshwater systems provide key pathways for microplastic (MP) pollution, and although existing studies have demonstrated the susceptibility of freshwater biota to ingestion, translocation, and trophic transfer, specific challenges pertaining to methodological standardization remain largely unresolved, particularly with respect to isolating, characterizing, and assessing MPs. Here, a critical review is performed outlining the challenges and limitations currently faced by freshwater MP researchers, which may well apply across the MP research spectrum. Recommendations are provided for methodological standardization, particularly in MP characterization, quality assurance, and quality control (QA/QC) procedures as well as reporting. Considerations for the assessment of MPs in freshwater biota as a means of improving comparisons between studies are discussed. Technological advancements, including the improvement of laboratory infrastructure for identifying MPs within the smaller size range as well as methodological standardization are essential in providing policy makers with tools and measures necessary to determine the distribution of MPs within freshwater ecosystems, while also allowing for comparability and providing compliance for future monitoring requirements.

“…Microplastics tend to be detected most frequently in the digestive tracts of aquatic animals. Their ingestion of plastic particles not only may cause mechanical damage, inflammation and microbiota dysbiosis of intestinal tracts (Burgos‐Aceves, Cohen, Smith, & Faggio, 2018; Guzzetti, Sureda, Tejada, & Faggio, 2018; Jin et al., 2018; Lei, Liu, et al, 2018; Qiao et al., 2019; Savoca et al., 2019), but it could also induce oxidative and immune stress, metabolic disorders and detoxification suppression in other vital tissues, such as livers, gills and haemolymph (Lei, Wu, et al, 2018; Yu et al., 2018). Moreover, microplastics can act as carriers of other pollutants such as heavy metal and persistent organic pollutants (POPs), thereby strengthening their biotoxicity (Rodríguez‐Seijo, Santos, da Silva, Cachada, & Pereira, 2019).…”

At present, research into the impact of microplastic contamination on environmental and food safety in the eel farming industry is insufficient. Here, we investigated the occurrence of microplastics in eels (Monopterus albus), wastewater and soils from recycled‐water, cement‐pool, net‐cage and rice‐field rearing systems. Results showed that average microplastic abundances were 2.4 ± 0.8 items/individual, 1.0 ± 0.4 items/L, 27.1 ± 7.0 items/kg in eels, water and soils, respectively. A significant increase in microplastic abundances occurred in all diet‐fed eels (recycled‐water, cement‐pool and net‐cage eels) from their pre‐rearing to post‐rearing stages. Moreover, cluster analysis indicated high similarities in composition of microplastics between fish diets and eels. However, no significant differences in microplastic abundances were observed among the four types of reared eels. Most of the microplastics were found in the foreguts of eels. In addition, wastewater microplastic increased significantly in the cement‐pool, net‐cage and rice‐field farming during eel rearing. This study first revealed microplastic contamination and its characteristics in eels‐rearing environments, which suggests the eco‐environmental risk of microplastics in aquaculture.
