Effect of size continuum from nanoplastics to microplastics on marine mussel Mytilus edulis: Comparison in vitro/in vivo exposure scenarios. Comp Biochem Physiol C Toxicol Pharmacol 2023; 264:109512.

Abstract
For several decades, plastic has been a global threat in terms of pollution. Plastic polymers, when introduce in the aquatic environment, are exposed to fragmentation processes into microplastics (MPs) and nanoplastics (NPs) which could potentially interact with living organisms. The objective of this work was to study the effects of plastic particles representative of those found in the environment, on the marine mussels Mytilus edulis, under two exposure scenarios: in vivo and in vitro. Whole mussels or cultured hemocytes were exposed for 24 h to NPs and MPs generated from macro-sized plastics collected in the field, but also to reference NPs, at concentrations found in the environment: 0.08, 10 μg and 100 μg·L-1. Results showed that immune response was only activated when mussels were exposed in vivo. However, cytotoxicity (hemocyte mortality) and genotoxicity (DNA damage) parameters were induced after both types of exposure, but in a dose-dependent manner after in vitro hemocyte exposure to all tested plastic conditions. These results indicate that in vitro approaches could be considered as potential predictors of in vivo exposures.

ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2022; 312:120082.

Abstract
Understanding the impacts of environmental pollutants on immune systems is indispensable in ecological and health risk assessments due to the significance of normal immunological functions in all living organisms. Bivalves as sentinel organisms with vital ecological importance are widely distributed in aquatic environments and their innate immune systems are the sensitive targets of environmental pollutants. As the central component of innate immunity, bivalve hemocytes are endowed with specialized endolysosomal systems for particle internalization and metal detoxification. These intrinsic biological features make them a unique cellular model for metal- and nano-immunotoxicology research. In this review, we firstly provided a general overview of bivalve's innate immunity and the classification and immune functions of hemocytes. We then summarized the recent progress on the interactions of metals and nanoparticles with bivalve hemocytes, with emphasis on the involvement of hemocytes in metal regulation and detoxification, the interactions of hemocytes and nanoparticles at eco/bio-nano interface and hemocyte-mediated immune responses to the exposure of metals and nanoparticles. Finally, we proposed the key knowledge gaps and future research priorities in deciphering the fundamental biological processes of the interactions of environmental pollutants with the innate immune system of bivalves as well as in developing bivalve hemocytes into a promising cellular model for nano-immuno-safety assessment.

Abstract
This review aims to (i) provide a current overview of the main characteristics of SiNP (physical and chemical properties, applications, and emissions), (ii) evaluate the scientific production up to date concerning SiNP, with focus on their toxic effects, through a bibliometric analysis, (iii) describe the main toxic mechanisms of SiNP, (iv) assess the current knowledge about ecotoxicity of SiNP on aquatic organisms (marine and freshwater), and (v) identify the main gaps in the knowledge of SiNP toxicity from an environmentally point of view. The scientific production of SiNP concerning their chemical and physical characteristics has increased exponentially. However, little information is available regarding their ecotoxicity. Particle functionalization is a key factor that reduces SiNP toxicity. Most of the studies employed standard species as test organisms, being the local/native ones poorly represented. Further studies employing long-term exposures and environmentally relevant concentrations are needed to deepen the knowledge about this emergent pollutant.

Revel M, Roman C, Châtel A. Is cell culture a suitable tool for the evaluation of micro- and nanoplastics ecotoxicity? ECOTOXICOLOGY (LONDON, ENGLAND) 2021; 30:421-430. [PMID: 33580466 DOI: 10.1007/s10646-021-02355-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Accepted: 01/20/2021] [Indexed: 06/12/2023]
Abstract
Plastic particles have been described in aquatic ecosystems worldwide. An increasing number of studies have tried to evaluate the toxic impacts of microplastics (1-5000 µm) but also nanoplastics (<1 µm) in marine and freshwater organisms. However, the wide variety of plastic particles characteristics such as various sizes, shapes, functionalization or types of polymer, makes it difficult to evaluate their impact with regular ecotoxicity testing. In this context, cell culture, mainly used in human toxicology, could be a promising tool to evaluate micro- and nanoplastics toxicity with a wide diversity of conditions allowing to generate a large set of data. This review presents the current research on micro and nanoplastics using cell culture of marine and freshwater organisms, describes the limitations of cell culture tool and defines whether this tool can be considered as a relevant alternative strategy for ecotoxic evaluation of micro and nanoplastics especially for future regulatory needs. Articles using specifically cell culture tool from aquatic organisms such as fish or bivalves were identified. The majority evaluated the toxicity of polystyrene nanobeads on immune parameters, oxidative stress or DNA damage in fish cells. Although most of the papers characterized nanoplastic particles into the cell culture media, the relevance of testing conditions is not always clear. The development of cell culture can offer many opportunities for the evaluation of plastic particles' cellular impacts, but more research is needed to develop relevant culture models, on various aquatic organisms, and with consideration of abiotic parameters especially composition of cell culture media for nanoplastic evaluation.
