“…Polystyrene microplastics exposed to adult zebrafish accumulated in the gastrointestinal tract and gill but were not detected in muscle and brain tissues. There was no oxidative stress and histological changes, however, induced behavioral abnormalities such as hyperactive swimming in the fish (Chen et al, 2020). On contrary, microplastics caused the overproduction of reactive oxygen species and alterations in the antioxidants parameters resulting in oxidative stress and DNA damage in Nile tilapia Oreochromis niloticus (Hamed et al, 2020).…”

“…Microbeads and microfibers are known to retain in the gastrointestinal tract of the goldfish, Carassius auratus showing 90% retention for 33.4 h, but there was no trace of net bioaccumulation in the gut or any tissues (Grigorakis et al, 2017). Polystyrene microplastics are found to accumulate in the gastrointestinal tract and gill tissue in the adult zebrafish that led to the thinning of the muscularis layer in the gut followed by hyperactivity and shortage of energysupplying substances (Chen et al, 2020). Accumulation of different shapes of microplastics observed in zebrafish caused intestinal injury and dysbiosis of gut microbiota (Qiao et al, 2019;Chen et al, 2020).…”

In another study, zebrafish exposed to polystyrene microplastics decreased body weight and caused metabolic disorder as a result of satiety and low intake of nutrients (Zhao et al, 2019).…”

The accumulation of plastic products in the terrestrial and aquatic environment is one of the major concerns in recent years. The quality of the ecosystem is affected globally due to the large production, ubiquitous usage, and poor plastic waste disposal. Plastic debris is categorized based on its size as macroplastics, mesoplastics, microplastics, and nanoplastics, respectively. Microplastics are the emerging contaminant that occurs in varying shapes like tiny beads, spheres, films, fragments, fibres, and filaments. The use of microplastics in cosmetics and abrasion from large plastic items including textile fibres and tyres are suspected to contaminate the environment when it reaches the aquatic ecosystem. Indian coastal waters are polluted by microplastics owing to industrialization, overpopulation, tourist and maritime activities. Many species of fishes, reptiles, birds, and mammals are directly threatened by entanglement or ingestion, and some marine mammals consume a large amount of microplastic debris by raptorial feeding thereby leads to trophic transfer. Humans are considered as the most exposed organisms than other vertebrates as they occupy at the top of the food chain. Certain government legislations have been put forth to ban some products that are considered as the major contributor to plastic debris. Recently, the use of bioplastics is increased all over the world to replace microplastics in industrial and commercial products. However, there is little awareness of the microplastic pollutants among the public, thus the main motive of this review is to provide public awareness and responsibility to limit the use of plastics that adversely damage our environment

“…According to the above research, the exposure of PE could inhibit the growth of Paralichthys Olivaceus weight and reduce the health status of Paralichthys Olivaceus, which may be due to the accumulation of PE in the intestines, disrupting the metabolic balance and causing respiratory and metabolic disorders. The research of Chen et al confirmed that exposure to MPs could reduce the thickness of the zebrafish's intestinal muscle layer [13]. This phenomenon was due to the thinning of muscle cells and loose connections, which would further affect the absorption of nutrients and ultimately put the zebrafish in an energy-depleted status.…”

In recent years, microplastics (MPs) pollution have become a global environmental issue, which aroused concern about their potential toxicity to marine organisms. However, due to the gradual depletion of natural resources, it had been rapidly developed in aquaculture. Therefore, this article studied the effect of polystyrene (PE) on the growth of Paralichthys Olivaceus. The surface of PE was rough and average size was 197.3 ± 11.2 μm. The contact angle of PE was 100.3 ± 2.5 °, which indicated that PE had a hydrophobic surface. PE exposure had no significant effect on the body length growth of fish, but compared with CK treatment, the weight growth of fish in PE treatment group was slower, which increased by 36.3% on the 28th day, but only increased by 10.9% in PE treatment group, indicating that PE could inhibit the growth of fish. PE led to the decrease of oxygen consumption rate of fish. On the 7th, 21st and 28th day, the oxygen consumption rate of fish decreased by 7.9%, 25.4% and 41.1%, respectively. Based on the above results, we concluded that marine MPs could inhibit the growth of the benthic economic fish, which would disturb the balance of the marine ecosystem.

“…However, behavioral alterations are considered as early warning signs since behavioral responses to environmental factors ( e.g ., anthropogenic pollutants) are reported to be 10–1,000 times more sensitive than commonly used endpoints like mortality, reproduction and development ( Hellou, 2011 ; Melvin & Wilson, 2013 ). In recent years, the swimming behavior or locomotion has been increasingly tested for freshwater species exposed to plastic particles of the nano ( Pikuda et al, 2019 ; Lin et al, 2019 ; Xu et al, 2020 ) and micro range ( Gorokhova et al, 2017 ; De Felice et al, 2019 ; Pannetier et al, 2020 ; Bartonitz et al, 2020 ; Xu et al, 2020 ; Chen et al, 2020 ; De Oliveira et al, 2020 ). To our knowledge, leachable chemicals derived from such particles have been rarely addressed in behavioral studies with freshwater invertebrates as by Xu et al (2020) .…”

Weathering of plastics leads to the formation of increasingly smaller particles with the release of chemical compounds. The latter occurs with currently unknown environmental impacts. Leachate-induced effects of weathered microplastics (MPs) are therefore of increasing concern. To investigate the toxicity of the chemical mixtures from such plastics, we exposed the freshwater shrimp Neocaridina palmata to enriched leachates from unweathered and artificially weathered (UV-A/B light) MPs (≤1 mm) from recycled low-density polyethylene (LDPE-R) pellets and from a biodegradable, not fully bio-based starch blend (SB) foil. We analyzed the individual locomotor activity (moved distance and frozen events) on day 1, 3, 7 and 14 of exposure to five leachate concentrations equivalent to 0.40–15.6 g MPs L−1, representing the upper scale of MPs that have been found in the environment. The median moved distance did not change as a function of concentration, except for the unweathered SB treatment on day 14 that indicated hyperactivity with increasing concentrations. Significant impacts were solely detected for few concentrations and exposure days. Generally, no consistent trend was observed across the experiments. We further assessed the baseline toxicity of the samples in the Microtox assay and detected high bioluminescence inhibitions of the bacterium Aliivibrio fischeri. This study demonstrates that neither the recycled nor the biodegradable material are without impacts on test parameters and therefore cannot be seen as safe alternative for conventional plastics regarding the toxicity. However, the observed in vitro toxicity did not result in substantial effects on the behavior of shrimps. Overall, we assume that the two endpoints examined in the atyid shrimp N. palmata were not sensitive to chemicals leaching from plastics or that effects on the in vivo level affect other toxic endpoints which were not considered in this study.
