Lakes are essentially interlinked to humans as they provide water for drinking, agriculture, industrial and domestic purposes. The upsurge of plastic usage, its persistence, and potential detrimental effects on organisms cause impacts on the trophic food web of freshwater ecosystems; this issue, however, still needs to be explored. Zooplankton worldwide is commonly studied as an indicator of environmental risk in aquatic ecosystems for several pollutants. The aim of the review is to link the existing knowledge of microplastic pollution in zooplankton to assess the potential risks linked to these organisms which are at the first level of the lacustrine trophic web. A database search was conducted through the main databases to gather the relevant literature over the course of time. The sensitivity of zooplankton organisms is evident from laboratory studies, whereas several knowledge gaps exist in the understanding of mechanisms causing toxicity. This review also highlights insufficient data on field studies hampering the understanding of the pollution extent in lakes, as well as unclear trends on ecosystem–level cascading effects of microplastics (MPs) and mechanisms of toxicity (especially in combination with other pollutants). Therefore, this review provides insight into understanding the overlooked issues of microplastic in lake ecosystems to gain an accurate ecological risk assessment.

“…Research has also found that ingestion of PS particles can cause damage to the liver and gills of rainbow trout, resulting in negative impacts on their health [ 21 ]. Scholars have also found that polystyrene microplastics can weaken the predator-induced defenses of Daphnia , which may have a certain impact on aquatic ecology [ 22 ]. Although many studies have investigated the toxicity of PS or PVC to aquatic animals, the differences in toxicity induced in aquatic species by PS and PVC are so far unknown.…”

The co-existence of microplastics (MPs) and methamphetamine (METH) in aquatic ecosystems has been widely reported; however, the joint toxicity and associated mechanisms remain unclear. Here, zebrafish larvae were exposed individually or jointly to polystyrene (PS) and polyvinyl chloride (PVC) MPs (20 mg/L) and METH (1 and 5 mg/L) for 10 days. The mortality, behavioral functions, and histopathology of fish from different groups were determined. PS MPs posed a stronger lethal risk to fish than PVC MPs, while the addition of METH at 5 mg/L significantly increased mortality. Obvious deposition of MPs was observed in the larvae’s intestinal tract in the exposure groups. Meanwhile, treatment with MPs induced intestinal deposits and intestinal hydrops in the fish, and this effect was enhanced with the addition of METH. Furthermore, MPs significantly suppressed the locomotor activation of zebrafish larvae, showing extended immobility duration and lower velocity. METH stimulated the outcome of PS but had no effect on the fish exposed to PVC. However, combined exposure to MPs and METH significantly increased the turn angle, which declined in individual MP exposure groups. RNA sequencing and gene quantitative analysis demonstrated that exposure to PS MPs and METH activated the MAPK signaling pathway and the C-type lectin signaling pathway of fish, while joint exposure to PVC MPs and METH stimulated steroid hormone synthesis pathways and the C-type lectin signaling pathway in zebrafish, contributing to cellular apoptosis and immune responses. This study contributes to the understanding of the joint toxicity of microplastics and pharmaceuticals to zebrafish, highlighting the significance of mitigating microplastic pollution to preserve the health of aquatic organisms and human beings.

“…Based on the existing data, MPs alone can affect algae (Cao et al, 2022;Guschina et al, 2020;Liu et al, 2020a;Wu et al, 2019;Zhang et al, 2017;Zheng et al, 2021). Moreover, it has been shown that MPs alone can induce toxic effects on aquatic invertebrate species including cnidarians (Beraud et al, 2022;Chen et al, 2022b;Lim et al, 2022;Marangoni et al, 2022), mollusks (Detree and Gallardo-Escarate, 2018;Green et al, 2019;Magni et al, 2019;Pedersen et al, 2020;Uguen et al, 2022;Weber et al, 2021;Zheng et al, 2022), cladocerans (Chenxi et al, 2022;Eltemsah and Bohn, 2019;Kokalj et al, 2018;Mondellini et al, 2022;Wang et al, 2022b;Wang et al, 2022c;Zebrowski et al, 2022), and echinoderms (Martinez-Gomez et al, 2017;Murano et al, 2020;Ng et al, 2022;Nobre et al, 2015;Rendell-Bhatti et al, 2021;Richardson et al, 2021;Trifuoggi et al, 2019). Also, fish species have been shown to be sensitive to the single effects of MPs (Banaei et al, 2022;Chen et al, 2017;Chen et al, 2020;Cormier et al, 2022;Felix et al, 2023;Jabeen et al, 2018;Kim et al, 2022;LeMoine et al, 2018...…”
