Functionalized polystyrene nanoplastic-induced energy homeostasis imbalance and the immunomodulation dysfunction of marine clams (Meretrix meretrix) at environmentally relevant concentrations

Abstract

The toxic mechanisms of functionalized polystyrene nanoplastics (NPs) to bivalves, especially regarding to energy homeostasis and immunity in benthic marine ecosystem, is poorly understood. Therefore in this study, the toxicity...

Does size matter? A proteomics-informed comparison of the effects of polystyrene beads of different sizes on macrophages

“…hemocytes) are found in invertebrates, as demonstrated in the 19th century by Metchnikoff. 64,65 It is therefore not surprising that alterations in the innate immune system have been described in response to micrometric microplastics and nanoplastics in annelids, 66 bivalves 67 and in fish. 68 This should be understood in parallel with the demonstration that plastic particles up to 10 μm can translocate from the mammalian intestine in the underlying immune tissue, 69 by mechanisms that are not well understood yet.…”

Influence of Functional Group Modification on the Toxicity of Nanoplastics

“…As for other aquatic animals, pre-fertilization exposure of sperm to PS-NH 2 NPs decreased offspring size and swimming performance in the European whitefish (Coregonus lavaretus) (Yaripour et al, 2021). PS-NH 2 NPs stimulated the increase in extracellular ROS, induced lysosomal damage, and decreased shell length in two kinds of mussels, Mytilus galloprovincialis (Canesi et al, 2015(Canesi et al, , 2016Balbi et al, 2017;Auguste et al, 2020a,b) and Meretrix (Liu et al, 2021). Compared with PS-COOH NPs, PS-NH 2 NPs induced severe developmental defects and genetic regulations in the development of sea urchin (Paracentrotus Lividus) embryos (Della Torre et al, 2014).…”
