“…In the present study, the total numbers of microplastics as well as microplastic abundance in the GIT and gills of A. persicus were higher than in C. aurata. However, the difference in microplastic abundance between these two species was not significant ( p > 0.05), which may be due to the feeding strategy of C. aurata , which feeds on detritus, benthic organisms, and even insects and planktons and subsequently ingests microplastics both from surface water and along with detritus (Zakeri et al, 2020), leading to the ingestion of more microplastics by this species. Similarly, Nematollahi et al (2021) and Zakeri et al (2020) reported higher abundance of microplastics in C. aurata compared with R. kutum and C. carpio in the Caspian Sea.…”

The increasing microplastic (MP) pollution in the marine environment has raised global concern. The main risk of MPs in aquatic ecosystem is their bioaccumulation in aquatic organisms. While some studies reported MPs pollution in the digestive system of the Caspian Sea fish species, there is no research on sturgeon species, nor on fish gills. Here, we investigated the occurrence of MPs in the gastrointestinal tract (GIT) and gills of 62 specimens belonging to four species including three teleosts (Cyprinus carpio, Rutilus kutum and Chelon aurata) and one sturgeon (Acipenser persicus, a valuable endangered species) from the Caspian Sea between January and March 2022. Fish tissues were removed, exposed for 24 h to 10 % KOH and then dried on the filter papers. Particles were observed under stereomicroscope and analyzed by Raman micro‐spectrometry, SEM and EDS. A total of 91 MPs were detected in GIT (averaged 1.46 ± 1.17 items/individual) and 63 MPs in gills (averaged 1.01 ± 0.62 items/individual). There was not significant correlation between the number of MPs found in the both tissues and the fish body length, body weight, GIT weight and gill weight (P > 0.05), except between MPs isolated from gills and gill weight in C. carpio (rs = 0.707, P = 0.022). MPs abundance in the fish followed the order of A. persicus > C. aurata > R. kutum > C. carpio. MPs were found in the size range of 45−5000 µm and the particles with 300‒1000 µm in size were the most prevalent. MPs were common by fiber (74.68 %) in shape, red (30.53 %) in color and nylon (70.6 %) in polymer.

“…According to previous studies (Harvey & Watts, 2018;Schwable et al, 2018), MPs have been found within human stools. These findings highlight that humans are exposed to MPs, and these particles can enter the human gut through the consumption of fish, bivalves, and crustaceans (Zakeri et al, 2020). This could result in the transport of not only MPs but also heavy metals to humans, affecting their immune systems and genetics (Brandts et al, 2018;Hwang et al, 2019).…”

The consequences of plastic waste pollution have imposed wide global concerns. One of these consequences is the production of micro- and nanosized particles (MNPLs) from aged plastics. The problem of MNPLs is magnified by their potential to transport various contaminants due to their large surface area and other variable physiochemical properties. From this point on, it is important to know the real concentration of MNPLs in our environment and their potential to internalize wild organisms as well as transfer contaminants that are completely highlighted. As a result, our study is the first to detect MP pollution in the upper Egypt wastewater environment. It could be utilized as a baseline to estimate MP wastes and develop management techniques, particularly in Sohag Governorate. The concentration and characterization of MPs in sludge, water, Chironomus sp. larvae, and their tubes were studied in this work. Chironomus sp. is a reliable bioindicator prevalent in such contaminated environments, and it was used to demonstrate how MPs invade biological barriers. Our results found that red and blue polyester fibers are much more prevalent than other polymers, colors, and shapes of MPs. While each dry kilogram of wastewater sludge contains 310 ± 84 particles, this amount is reduced to 1.55 ± 0.7 per liter in the water column. Biologically, the present study succeeded in detecting the MPs inside the wild organism, with concentrations reaching 71 ± 21 and 4.41 ± 1.1 particles per gram wet weight in Chironomus sp. larvae and their tubes (chironomid tubes), respectively. The potential hazard of MPs stems from their propensity to transfer pollutants. At this point, our findings revealed a corresponding and significant concentration of various heavy metals (Cu, Pb, Cd, and Ni) detected in MPs or Chironomus sp. versus sludge. In conclusion, our findings not only proved the presence of MPs in wastewater but also demonstrated their ability to internalize cross-wild organisms, allowing toxins to accumulate inside their bodies, raising concerns about the possible health impacts of plastic pollution.

“…There is an exponential increase in the number of studies looking at the presence of microplastics in marine and aquatic biota [17,19,57,59,60,81,83,89,102,[194][195][196][197][198][199][200][201][202][203]. Microplastics find their way into biota usually by ingestion (active uptake) [102,204,205] or adhesion, adsorption, or inhalation (passive uptake).…”

“…The origin of MP in the aquatic environment is often linked to the colossal quantity of plastic entering mainly from poorly managed plastic waste disposal [32,41,47,53,81,82]. The chronic exposure of MP in the aquatic environment poses various issues such as inducing inflammation, malnutrition, reproductive behavior and capacities [57,[83][84][85][86][87][88][89], and toxicity caused by the polymer used for manufacturing plastic products [60,[90][91][92][93]. The potential of MPs to adsorb hydrophobic contaminants due to their extremely large surface-to-volume ratio and long residence time in the water column [94,95] has attracted much attention in the scientific community [7,16,32,47,53,70,71,87,[96][97][98][99][100][101][102][103][104][105][106][107][108][109][110][111].…”

Microplastic research has become a buzz word. It is seen as one of the most pressing issues of Anthropocene contamination. There is certainly no doubt about the ubiquitous presence of microplastic (MP) in almost all environmental matrices. However, the validity of considering them as a vector for contaminants needs some reconsideration, there are other more potent pathways. Their effect on marine biota also calls for some realistic experiments with environmental concentrations of MP and nanoplastic (NP). It has been observed that in most published literature, polymer characterization is performed. Is it necessary to do, or will merely finding and confirming the particle as plastic suffice for environmental research? Harmonization of protocols is necessary, and there is likely a need for some inter-laboratory comparison exercises in order to produce comparable data and reliable assessments across regions. Samples collected from the same area using different techniques show an order of magnitude difference in MP concentration. The issue of nanoplastic is more contentious; are we technologically ready to identify NP in environmental samples?
