“…In addition, chemical additives leaching from plastics can further contribute to ROS formation (Hu and Palić, 2020;Yang et al, 2020). Oxidative challenge of MPs/NPs exposure was extensively supported by significant changes in antioxidant defenses (i.e., CAT, SOD, GST, GPx and GSH) both at catalytic and transcriptional level and by the onset of oxidative damages to lipids, proteins and DNA (reviewed in Trestrail et al, 2020, Gonçalves and Bebianno, 2021, that was even observed after exposures to environmentally realistic concentrations of MPs (Hariharan et al, 2021) and persistent also after a period of depuration (Hariharan et al, 2021;Capó et al, 2021). These effects suggest that MPs/NPs, as other pro-oxidant stimuli, can activate expression of antioxidant genes via the Nrf2dependent mechanism.…”

“…This can be explained because the larger inhalant siphon of S. purpurata can ingest more microplastics when filtering food. In addition, Hariharan et al (2021) found green mussels (Perna viridis) exposed to polyethylene microplastics, and intestinal tissue exhibited a higher number of particles than the other portions. The proportion of digestive glands to soft tissue is relatively small in S. purpurata.…”

Microplastic pollution to the marine environment is a global issue. This study investigated microplastic pollution in ten species of different mollusks. Microplastic shape and size were determined under a microscope. Additionally, the polymer types were identified using Fourier transform infrared microspectroscopy (μ-FT-IR). The results showed that the microplastic abundance varied from 0.19 to 1.76 items/g (wet weight) and 4.3 to 36.6 items/individual. Four types of microplastics were observed, including fibers, fragments, films, and pellets. Fibers smaller than 500 μm were the most common. Cellophane (CP) and polyethylene terephthalate (PET) were the main polymer types. The microplastic abundance in the buried bivalve Ruditapes philippinarum demonstrated the highest level of microplastic contamination assessed by wet weight (1.76 ± 0.95 items/g). Furthermore, the Spearman correlation test showed that there was a significant negative correlation between the microplastic abundance calculated by weight and the biometric parameters (shell length, shell height and soft tissue wet weight). Our results will provide valuable information for assessment of the potential health risks of microplastics in China's seafood.

“…Studies covering a wide range of aquatic and terrestrial animal species indicated that oxidative stress, due to increased ROS production in cells and tissues, is a major molecular event triggered by MP/NP exposure ( Supplementary Tables S1, S2 ). Increased ROS levels and/or altered expression of oxidative stress defense system were detected upon MP/NP exposure in the marine rotifer Brachionus species, copepods ( Tigriopus japonicus ) ( Xue et al, 2021 ; Yoon et al, 2021 ), Daphnia species ( Liu et al, 2021b ), green mussel ( Perna viridis ) ( Hariharan et al, 2021 ), marine medaka ( Oryzias melastigma ), zebrafish ( Danio rero ) ( Qiang and Cheng, 2021 ), Nile tilapia ( Oreochromis niloticus ) ( Ismail et al, 2021 ), as well as terrestrial organism including Eisenia sp. , rat and mouse .…”

Microplastics and Their Impact on Reproduction—Can we Learn From the C. elegans Model?

Biologically active environmental pollutants have significant impact on ecosystems, wildlife, and human health. Microplastic (MP) and nanoplastic (NP) particles are pollutants that are present in the terrestrial and aquatic ecosystems at virtually every level of the food chain. Moreover, recently, airborne microplastic particles have been shown to reach and potentially damage respiratory systems. Microplastics and nanoplastics have been shown to cause increased oxidative stress, inflammation, altered metabolism leading to cellular damage, which ultimately affects tissue and organismal homeostasis in numerous animal species and human cells. However, the full impact of these plastic particles on living organisms is not completely understood. The ability of MPs/NPs to carry contaminants, toxic chemicals, pesticides, and bioactive compounds, such as endocrine disrupting chemicals, present an additional risk to animal and human health. This review will discusses the current knowledge on pathways by which microplastic and nanoplastic particles impact reproduction and reproductive behaviors from the level of the whole organism down to plastics-induced cellular defects, while also identifying gaps in current knowledge regarding mechanisms of action. Furthermore, we suggest that the nematode Caenorhabditis elegans provides an advantageous high-throughput model system for determining the effect of plastic particles on animal reproduction, using reproductive behavioral end points and cellular readouts.
