“…MPs have been found in more than 600 species of organisms (Toussaint et al 2019), in human food such table salt (Peixoto et al 2019), beer (Kosuth et al 2018) and drinking water (Mason et al 2018) on all continents including the America (McEachern et al 2019), Antarctica (Bessa et al 2019), Europe (Sadri & Thompson 2014), and Asia (Sarkar et al 2019). The adverse effects of MPs are well documented on diverse array of marine organisms (Wright et al 2013;Güven et al 2017;Iṡinibilir Okyar et al 2020;Svetlichny et al 2021).…”

Wastewater treatment plants (WWTPs) are one of the major vectors of microplastics (MPs) pollution for the recipient water bodies. Therefore, the recovery of MPs from WWTPs is extremely important for decreasing their accumulation and impact in aquatic systems. In this present study, the electrocoagulation-electroflotation (EC/EF) and membrane filtration processes were investigated in removing MPs from wastewaters. The effectiveness of different electrode combinations (Fe-Al and Al-Fe), current density (10–20 A/m2), pH (4.0–10.0) and operating times (0–120 min) on the removal of two different polymer particles in water were investigated to obtain maximum treatment efficiency. The effect of pressure (1–3 bar) on membrane filtration removal efficiency was also investigated. The maximum removal efficiencies were obtained as 100% for both polymer types with electrode combination of Al-Fe, initial pH of 7, current density of 20 A/m2 and reaction time of 10 min. The membrane filtration method also displayed a 100% removal efficiency. In addition, these laboratory-scale results were compared with the one-year average data of a plant treating with real-scale membranes. The results indicated that the proposed processes were supplied maximum removal efficiency (100%) compared to conventional secondary and tertiary treatment methods (2–81.6%) in the removal of microplastics.

“…A previous study recorded different feeding modes for P. annandalei when dealing with different prey sizes and mobilities (Dhanker et al, 2013). MP-driven alterations in the behavioral and physiological responses of the calanoid copepods Acartia clausi and C. typicus have been attributed to differences in the feeding strategies of the two species (Svetlichny et al, 2021). Further comparative studies are required to understand the role of different feeding strategies in the uptake of MP by P. annandalei.…”

“…The feeding capacity and metabolic rates of calanoids, Centropages typicus and Calanus helgolandicus were significantly reduced in the presence of 6 mm-12 mm polystyrene beads (>4,000 MPs mL −1 ) (Cole et al, 2013;Isinibilir et al, 2020). However, another recent study by Svetlichny et al (2021) showed an increase in the consumption rate of pure microplastics in a mixture of microplastic beads (6mm diameter) and algae Rhodomonas salina (5 mm-10 mm size range) with equal concentrations of approximately 5,000 cells/beads mL −1 . The presence of micro-and nano-sized polystyrene in the environment has been observed to alter the feeding behavior of diving beetle (Cybister japonicas) and crucian carp (Carassius carassius) (Kim et al, 2018).…”

Being chemically inert and morphologically similar (<5 mm in size) to the natural prey of copepods, microplastics (MPs) affect them through entanglement, ingestion, and interference with their natural prey selection. The effects of external factors, such as MP, can be observed in the form of alterations in the functional and numerical responses of copepods. Functional response is explained as the relationship between the intake rate of a consumer and the amount of food available in a particular ecotope. Considered three types of functional response: (i) with increasing food density, when intake rate increases linearly until asymptote, called Type-I functional response; (ii) when the proportion of prey ingested by the consumer decreases monotonically with prey density, considered as a Type-II functional response; and (iii) when ingestion rate and food density show a sigmoid relationship, is considered as Type-III functional response. In the present study, we attempted to elucidate the effects of MP on the functional responses of brackish water, demersal, calanoid copepod, Pseudodiaptomus annandalei, feeding on the rotifer Brachionus rotundiformis, and the ciliate Frontonia microstoma. The ability of P. annandalei to survive environmental fluctuations and its nutritional value make it an ecologically important organism in estuarine ecosystems. The experiment for estimation of functional response included four setups with adult and copepodite stages of P. annandalei, each with six replicates at six different prey densities, in the presence and absence of MP particles. Without MPs, P. annandalei showed a typical Type-II functional response, where the proportion of prey consumed significantly declined with increasing prey density. In the MP-applied medium, the proportion of prey consumed did not exhibit a significant relationship with the initial prey density. The number of ciliates and rotifers ingested by copepodites and adults was significantly lower in MP-contaminated medium than in prey either monospecific or in combination with microalgae. Because of the comparable size of MP to the prey species and unspecialized feeding of P. annandalei in natural waters, we hypothesized reduced predation rates as a result of pseudo-satiation resulting from MP ingestion leading to malnutrition and MP storage in copepod biomass.

“…The effects of microplastics on the respiration regulation in aquatic crustaceans could be detected by changes in respiration rate. For Copepoda, polystyrene reduced the respiration rates in Centropages typicus and Acartia clausi by 3.4 and 2.2 times, respectively [ 138 ]. Moreover, 6, 12 and 26 µm polystyrene could significantly reduce the C. helgolandicus respiration rate [ 139 ].…”

It is impossible to overlook the effects of microplastics on aquatic life as they continuously accumulate in aquatic environments. Aquatic crustaceans, as both predator and prey, play an important role in the food web and energy transmission. It is of great practical significance to pay attention to the toxic effects of microplastics on aquatic crustaceans. This review finds that most studies have shown that microplastics negatively affect the life history, behaviors and physiological functions of aquatic crustaceans under experimental conditions. The effects of microplastics of different sizes, shapes or types on aquatic crustaceans are different. Generally, smaller microplastics have more negative effects on aquatic crustaceans. Irregular microplastics have more negative effects on aquatic crustaceans than regular microplastics. When microplastics co-exist with other contaminants, they have a greater negative impact on aquatic crustaceans than single contaminants. This review contributes to rapidly understanding the effects of microplastics on aquatic crustaceans, providing a basic framework for the ecological threat of microplastics to aquatic crustaceans.
