“…The peaks of different innate immune parameters' values reported in previous studies may not be completely similar in magnitude and time (Asmonaite et al, 2018;Wang et al, 2022). In this study, the expression of immunity-related genes, including HSP70, IL1β, IFN-γ, and TNF-α, was higher in the PS-NPs-fed treatments than in the control group.…”

This trial was performed in order to investigate the response of zebrafish (Danio rerio) to dietary exposure to polystyrene nanoplastics (PS‐NPs) under laboratory conditions on fish growth and health. Healthy zebrafish (n=240) were divided into 12 tanks and fed with diets including 0 (T0), 100 (T1), 500 (T2), and 1000 (T3) mg kg−1 synthesized polystyrenes nanoplastics (PS‐NPs) for 30 days. At the end of trial, fish fed the PS‐NPs supplementation showed weight gain percentages of 79.45%, 70.35%, and 61.88% for T1, T2, and T3 groups, respectively, compared with 87.39% in the control fish. The SOD, GPX and MDA activities and cortisol levels increased by 47%, 32% and 35% and 46%, respectively, especially at high‐dose administration (p < 0.05). The expression of GPX (T2‐81% and T3‐82%) and SOD (T2‐101% and T3‐187%) were remarkably upregulated in T2 and T3 groups. Moreover, the relative gene expression of HSP70, interleukin‐1 (IL1), Interferon γ (IFN‐γ) and tumor necrosis factor‐α (TNF‐α) increased by 178%, 202%, 154% and 307%, respectively, especially at high‐dose administration (p < 0.05). The results of the present study demonstrated that exposure to PS‐NPs especially at high concentrations (500 and 1000 mg kg−1 of diet) negatively influenced growth, health status‐, antioxidant‐, and immunity‐related gene expression responses of zebrafish.

“…The toxic effects of MPs on the liver are receiving more attention from researchers. Currently, the research on the toxic effects of MPs/NPs on the liver mainly focuses on marine fish [ 69 , 124 ]. Since the pollution of MPs in the ocean is not optimistic, and fish are the main marine species that people eat, it is crucial to study the impact of MPs on marine fish.…”

Plastics in the environment can be degraded and even broken into pieces under the action of natural factors, and the degraded products with a particle size of less than 5 mm are called microplastics (MPs). MPs exist in a variety of environmental media that come into contact with the human body. It can enter the body through environmental media and food chains. At present, there are many studies investigating the damage of MPs to marine organisms and mammals. The liver is the largest metabolizing organ and plays an important role in the metabolism of MPs in the body. However, there is no available systematic review on the toxic effects of MPs on the liver. This paper summarizes the adverse effects and mechanisms of MPs on the liver, by searching the literature and highlighting the studies that have been published to date, and provides a scenario for the liver toxicity caused by MPs.

“…Currently, the studies published on in vivo nanoplastics exposure are increasing, for example the studies from Auguste et al , 61 Elizalde-Velázquez et al 62 and Wang et al 63 In addition, ex vivo studies are gaining interest as well. 64 However, more studies are needed to clarify the mechanisms for bioaccumulation of nanoplastics in mammals.…”
