“…The decrease of speed caused by MPs suggested that aquatic organisms ingesting MPs might not only reduce predation, but also be exposed to high risk of being preyed upon. Rist et al (2017) reported that the microalgae ingestion rate of Daphnia magna significantly decreased by 21% after exposure to 1 mg/L polystyrene (PS) MPs for 24 h. Similarly, MPs-induced inhibition of feeding activity was also observed in Neomysis japonica, with a maximum of 20% at 250 μg/L PS MPs for 0.5 h (Wang et al, 2020). As proposed by Rotjan et al (2019), MPs were barriers to food intake.…”

“…In terms of the predation risk, Seuront (2018) evaluated the effect of environmentally relevant MP leachates on the predator (Carcinus maenas) -prey (Littorina littorea) interaction, indicating the increase of vulnerability and the decrease of escape response of L. littorea. In addition, the moved distance was a reflection of the explorative ability, and its reduction implied that after MP exposure, aquatic organisms tended to stay closer together in small-scale areas against the harsh environment, that was, the shoaling behavior (Gerlai, 2014;Mattsson et al, 2015;Wang et al, 2020). Correspondingly, the shoaling behaviors of zebrafish (Danio rerio) and black rockfish (Sebastes schlegelii) induced by MPs at environmentally relevant concentrations were revealed by Sarasamma et al (2020) and Yin et al (2019), respectively, which was reflected in the average inter-fish distance significantly decreased by 7-74% compared with control groups (Fig.…”

“…To really assess whether these are negligible or not, it could be beneficial to use our study as a baseline and adjust the test variables. We applied similar test variables in terms of acclimatization period ( Chen et al, 2020 ; Wang et al, 2020 ), recording time ( Wang et al, 2020 ) and replicate number per treatment as other studies ( Gerhardt, 2020 ; Xu et al, 2020 ). It is noteworthy that the test variables for the assessment of the swimming activity can vary greatly ( Faimali et al, 2017 ; Siregar et al, 2021 ; Sun et al, 2021 ).…”

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.

“…In the small crustaceans A. franciscana and Paracyclopina nana, some changes in enzymes were identi ed (Gambardella et al 2017;Jeong et al 2017). Irregular shaped MPs harmed the larvae's swimming behaviour, reducing the total distance travelled and maximum velocity (Yu et al 2020;Wang et al 2020b).…”

The ubiquitous presence of microplastics (MPs) in all oceans has become a significant threat to nature as global plastic production continues to increase. Now, and over the next 20 to 30 years, it is the time to address the consequences of the rise of the plastic industry global production of millions of items, ranging from a single pen to automobiles. Inappropriate management, lack of awareness of the harmful effects, reckless universal use, and indiscriminate disposal of plastics have turned the earth into a "plastic planet”. The aim of the present study review is to identify the scenarios for the structure, and functions of MPs and the resulting impacts on marine organisms. The different origins of MPs in the oceans and their negative impacts on marine organisms are critically discussed in this review. Due to their small size, these plastic particles are easily ingested by a wide range of marine organisms (e.g., fish, Mollusca, Arthropoda, Annelida, Echinodermata, Nematoda, phytoplankton, zooplankton, algae, birds, Mammalia, marine reptiles, and corals), posing a threat to their health. The ability of MPs to absorb a variety of hazardous hydrophobic chemicals from the environment allows transfers these toxins to enter directly into the food chain, ultimately becoming a threat to human health. As a result, numerous policies and laws have been created to address the major problems of marine pollution. However, these regulations need to be improved and implemented worldwide. To avert future threats, it is crucial to stop the production of toxic chemicals associated to the production of plastics and replaces them with environmentally suitable alternatives.
