Microplastics, as a currently emerging pollutant, are gaining increasing attention from researchers in various fields. The purpose of this study is to summarize research development on microplastics in the field of neurotoxicity using bibliometric tools and visualization methods and to identify current research hotspots. The Web of Science Core Collection (WoSCC) was searched under the topics of “microplastics” and “neurotoxicity.” A total of 33 published articles were obtained by exclusion and analyzed using CiteSpace (V6.1.R2). It was found that microplastic neurotoxicity research is currently on the rise, with the most research results being published in China, the most collaboration occurring between Italy and other countries, and the least collaboration occurring between authors. The focus and hotspots of future research on the neurotoxicity of microplastics may revolve around “accumulation” and “integrated biomarker response.” These findings demonstrate the trends and frontiers in the field of microplastic neurotoxicity research and provide valuable information for subsequent research directions and potential collaborations.

“…The first hypothesis must therefore be rejected, as the sediment rather serve as a reservoir than a final sink of MPs. General fate processes (A) and occurrence of effects (bold numbers) and effects tested (numbers in brackets), based on 10 effect studies of sediment-associated MPs (B) (Besseling et al, 2013;Wright et al, 2013;Van Cauwenberghe et al, 2015a;Green et al, 2016;Bour et al, 2018;Gomiero et al, 2018;Leung et al, 2018;Hope et al, 2020;Urban-Malinga et al, 2021;Urban-Malinga et al, 2022). Each endpoint studied in a specific experimental condition (i.e., combination of concentration, duration, polymer type) was counted as one observation, and for each observation we recorded whether a significant effect was reported at the lowest observed effect concentration (LOEC).…”

Sediment matters as a route of microplastic exposure: A call for more research on the benthic compartment

Microplastics (MPs) are ubiquitous in the marine environment. Here, most MPs are expected to sink, either due to polymer density or environmental processes, such as biofouling, leading to sediment being proposed to act as a final sink for marine MPs. There is a discrepancy between the anticipated accumulation of MPs in the sediment compartment and the MP experiments conducted, since most MP effect studies have been conducted with pelagic species using water-only exposures. Here we address fundamental questions in relation to MP pollution to close the knowledge gap related hereto. A systematic literature search was performed to address these questions. We found that benthic invertebrates ingest MPs and that, even though these organisms evolutionary are adapted to handle particles, adverse effects may be observed upon ingestion of MPs. The analysis further revealed that there is a major knowledge gap on the impacts of sediment-associated MPs in marine, benthic invertebrates. To facilitate further and structured research within this topic, we recommend more studies with emphasis on the sediment as an important exposure pathway, and to focus on sediment-associated MP effects on benthic invertebrates. We recommend studies with ecological relevant exposure concentrations and ecological relevant exposure durations with emphasis on impacts on population- and community-level to reduce the knowledge gap within this central area of MP pollution research.

“…Although there has been little research on this topic, a reduction in the survival rates of deposit feeding organisms like Chironomus tepperi and Caenorhabditis elegans exposed to microplastics has been previously reported. In contrast, other exposure studies did not find any adverse effects on growth and survival. − In aquatic benthic organisms, it has been shown that microplastics could significantly decrease energy reserves, , increase lipid peroxidation, trigger oxidative enzymes, and generate neurotoxicity . However, it has also been reported that exposing deposit feeders to microplastics did not affect their energy storage nor cause any oxidative damage .…”

While microplastic transport, fate, and effects have been a focus of studies globally, the consequences of their presence on ecosystem functioning have not received the same attention. With increasing evidence of the accumulation of microplastics at sediment−water interfaces there is a need to assess their impacts on ecosystem engineers, also known as bioturbators, which have direct and indirect effects on ecosystem health. This study investigated the impact of microplastics on the bioturbator Tubifex tubifex alongside any effects on the biogeochemical processes at the sediment−water interface. Bioturbators were exposed to four sediment microplastic concentrations: 0, 700, 7000, and 70000 particles kg −1 sediment dry weight. Though no mortality was present, a significant response to oxidative stress was detected in tubificid worms after exposure to medium microplastic concentration (7000 particles kg −1 sediment dry weight). This was accompanied by a reduction in worm bioturbation activities assessed by their ability to rework sediment and to stimulate exchange water fluxes at the sediment−water interface. Consequently, the contributions of tubificid worms on organic matter mineralization and nutrient fluxes were significantly reduced in the presence of microplastics. This study demonstrated that environmentally realistic microplastic concentrations had an impact on biogeochemical processes at the sediment−water interface by reducing the bioturbation activities of tubificid worms.
