“…The average concentration of MP accumulated in the digestive tract by kg of fish was 20.11 ± 2.94 MP kg −1 , in the range reported by [ 25 ] in other carnivorous species from the Bohai Sea; i.e., Scomberomorus niphonius (10 ± 11 MP kg −1 ), Sebastods schlegelii (41 ± 47 MP kg −1 ), Thryssa mystax (87 ± 48 MP kg −1 ), Eupleurogrammus muticus (31 ± 18 MP kg −1 ), Seriola aureovittata (7 ± 6 MP kg −1 ), Freeze myriaster (20 ± 9 MP kg −1 ), Lateolabrax maculatus (17 ± 11 MP kg −1 ), Paralichthys olivaceus (10 ± 35 MP kg −1 ), or Saurida elongate (66 ± 35 MP kg −1 ). As depicted in Figure 3 a, FB was by far the most abundant shape (71.68%; 15.04 ± 2.44 FB kg −1 fish), followed by fragment (FR) (21.15%; 3.50 ± 1.02 FR kg −1 fish), film (FI) (6.81%; 1.52 ± 0.50 FI kg −1 fish), and microbead (BD) (0.36%; 0.04 ± 0.04 BD kg −1 fish).…”

“…Average numbers of MP by stomach and intestine were 7.88 ± 1.77 and 8.53 ± 2.19, respectively, without statistically significant differences ( F -test = 3.133, p = 0.053), being higher than those reported by [ 23 ] in 110 specimens of Sparus aurata from the Turkish coast, with average values of 1.53 and 1.47 MP for stomach and intestine, respectively. Average abundance of 16.41 MP per fish was higher than 1.2 MP per individual reported by [ 32 ] in 761 individuals from mesopelagic families; 2.3 MP per individual in 64 Japanese anchovies, with a maximum of 15 pieces per individual [ 33 ]; 1.2 MP per individual in 189 fish specimens from the Amazon River estuary [ 34 ]; 2.14 MP per individual reported by [ 25 ] in the Bohai Sea; or 4.3 items per wild mullet reported by [ 15 ]. The authors of [ 35 ] reported 88 particles in the whole digestive tract from three adult female whales stranded on the North and West Ireland coast, and [ 36 ] reported a concentration of 19.7 microplastics per individual, in gut contents of 11 species from an Argentinean coastline estuary.…”

This paper presents the results on the presence and characterization of microplastics (MP) in the gastrointestinal tract of gilthead seabream (Sparus aurata L.), a species of commercial interest from the Mar Menor coastal lagoon in Southeast Spain. This is the first time that microplastic ingestion is recorded in any species from this semi-enclosed bay. Stomach and intestine from a total of 17 specimens captured by local fishermen were processed, and microplastic particles and fibers found in all of them were displayed. Overall, 40.32% (279/692) of total isolated microparticles proved to be microplastics; i.e., <5 mm, as identified by FTIR spectroscopy. The average value by fish was 20.11 ± 2.94 MP kg−1, corresponding to average concentrations of 3912.06 ± 791.24 and 1562.17 ± 402.04 MP by kg stomach and intestine, respectively. Four MP forms were isolated: fiber (71.68%), fragment (21.15%), film (6.81%), and microbead (0.36%), with sizes ranging from 91 µm to 5 mm, an average of 0.83 ± 0.04 mm, and no statistically significant differences between mean sizes in stomach and intestine samples (F-test = 0.004; p = 0.936). Nine polymer types were detected, although most of fibers remained unidentified because of their small size, the presence of polymer additives, or closely adhered pollutants despite the oxidizing digestion carried out to eliminate organic matter. No significant correlation was found between main biological parameters and ingested microplastics, and high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyethylene polypropylene (PEP), and polyvinyl (PV) were identified as the most abundant polymers. The average microplastic ingestion in this study area was higher than those reported in most studies within the Mediterranean Sea, and closely related to microplastic pollution in the surrounding area, although with a predominance of fiber form mainly due to fishery activities.

“…This study provided the first published characterization record of microplastics by FT-IR in the gastrointestinal tract and gills in both pelagic and demersal fish in the eastern coastal water of Thailand. The proportion of fish to have ingested plastics (13%) was less than those recorded by [25], showing 36.5% of 504 fishes (five demersal and five pelagic species) from the English Channel, 33% of 122 catfish from Brazil [51], 35.5% of commercially caught fish across southern Australia [28], 33% of six fish species of commercial importance in central Chile [52], and 85.4% of 29 of the commercial fish species from the Bohai Sea in China [53]. However, results of this study presented a higher frequency of microplastic in fish found compared to other areas of Thai water [39].…”

Presence and Characterization of Microplastics in Coastal Fish around the Eastern Coast of Thailand

Marine microplastic has been in the limelight recently. This study aimed to describe microplastic types ingested by 274 fish from Thailand’s eastern coast in 2020 and to compare the microplastic content among different feeding traits. The microplastics in the gastrointestinal tracts and gills were extracted, analyzed, and identified using FT-IR spectroscopy. Approximately 13.14% of the total specimen ingested microplastics, with an average of 0.14 items per individual. The detection frequency of microplastics was relatively high compared with other regions in Thailand but relatively low compared to global standards. Of the microplastic contaminated specimens, 56.41% had at least one piece of microplastic in their gastrointestinal tract. Pelagic (14.47%) species were found to have ingested more microplastics than the demersal (12.63%) group. Dominant aspects found included PET (as in polymers), fiber (as in shape), and black (as in color). However, microplastic numbers fluctuated with the size, weight, and feeding behavior of fish. This result suggested that the pelagic has a higher exposure risk and microplastic ingestion in relatively small quantities in a range of fish species. Our results indicated that the occurrence of microplastics in fish is not influenced by organism habitat or trophic level, although the characteristics of pelagic fish might significantly increase the chance of exposure to microplastics in pelagic species.

“…Cellophane was the most common polymer found in all fish (56.8%), followed by PA (20.0%), PET (8.8%), and polyarylamide (PARA; 5.6%). Wang et al [48] presented an analysis of microplastic uptake by 29 commercial fish species with different feeding habits and trophic levels from the Bohai Sea, China. Approximately 85.4% of all fish were found to have ingested microplastics.…”

The amount of plastic waste and microplastics released into marine environments has increased rapidly in recent decades. The durability of plastic materials results in major problems following their release into the environment. This study provides an overview of recent findings on issues related to plastic degradation, the accumulation of microplastics in mussels and fishes, and the toxicological effects associated with the ingestion of microplastics. These findings confirm the serious problem of slowly degrading plastics (which rarely degrade fully) in natural marine environments. Microplastics have become widespread pollutants and have been detected in mussels and fish around the world. Microplastic particles, whether virgin or with adsorbed pollutants on their surfaces, pose a health problem after being ingested by marine organisms. This paper ends by highlighting the need for certain improvements in studies of these phenomena.
