“…For large fish, the stomach and/or gastrointestinal tract (GIT) was isolated and digested to detect microplastics [ 9 , 25 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 60 , 61 , 62 , 63 , 65 , 66 , 67 , 68 , 69 , 70 , 72 , 73 , 74 , 75 ]. Unlike the digestion method used for sea salts, various chemicals were used to decompose organic materials, including potassium hydroxide (KOH) [ 9 , 22 , 23 , 38 , 45 , 47 , 48 , 53 , 55 , 56 , 58 , 62 , 64 , 71 , 74 , …”

“…Higher digestion temperatures could shorten the required time, but they increase the possibility for thermoplastic loss [ 100 ]. Microscopic analysis coupled with FT-IR spectroscopy was the most popular method for chemical identification of microplastics [ 9 , 25 , 39 , 40 , 41 , 42 , 44 , 45 , 46 , 47 , 48 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 61 , 64 , 69 , 70 , 71 , 73 , 74 , 75 ]. Raman spectroscopy was also applied [ 59 , 62 ] due to its enhanced performance with smaller particles [ 100 ].…”

“…Microplastics were rarely found in edible tissues, such as muscle [ 9 , 22 , 59 , 64 , 71 ], but they were predominantly found in digestive tracts [ 9 , 22 , 23 , 25 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 60 , 61 , 62 , 63 , 65 , 66 , 67 , 68 , 69 , 70 , 72 , 73 , 74 , 75 ]. Because it is unclear how microplastics are transported to edible tissues, human exposure to microplastics due to the consumption of edible fish tissue requires further evaluation.…”

“…Microplastics were also extensively monitored in shellfish, such as blue mussels, shrimps, and clams [ 11 , 20 , 40 , 45 , 52 , 59 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 ] ( Table 3 ). Unlike fish, soft tissues were dissected and digested to separate microplastics in mussels, clams, and oysters.…”

Human exposure to microplastics contained in food has become a significant concern owing to the increasing accumulation of microplastics in the environment. In this paper, we summarize the presence of microplastics in food and the analytical methods used for isolation and identification of microplastics. Although a large number of studies on seafood such as fish and shellfish exist, estimating the overall human exposure to microplastics via food consumption is difficult owing to the lack of studies on other food items. Analytical methods still need to be optimized for appropriate recovery of microplastics in various food matrices, rendering a quantitative comparison of different studies challenging. In addition, microplastics could be added or removed from ingredients during processing or cooking. Thus, research on processed food is crucial to estimate the contribution of food to overall human microplastic consumption and to mitigate this exposure in the future.

The presence of microplastics in different environmental matrices has raised many concerns about potential effects of microplastics on humans and freshwater ecosystems. In Pakistan, rivers potentially receive microplastics from anthropogenic activities in their catchments. However, research studies regarding microplastics' presence, distribution, and risks are scarce in Pakistan. To bridge the gap, the present study was conducted to evaluate microplastic pollution in the Chenab River. Surface water samples were collected from selected sites on the Chenab River using a manta trawl in the low-flow season during postmonsoon (October) 2019 and 2020 and in the high-flow season during monsoon (July) 2020 and 2021. Samples were digested, followed by density separation and filtration. Identification and polymer characterization of microplastics were completed using stereomicroscopy and attenuated total reflection Fourier transform infrared spectroscopy, respectively. Microplastics were found in all samples with significant spatiotemporal variation in microplastic concentration, with an average of 45.98 ± 10.45 microplastics/m 3 in the low-flow season and 34.66 ± 16.15 microplastics/m 3 in the high-flow season. Among microplastic shapes, fibers were the most dominant shape, whereas polyethylene terephthalate (38.2%) and polypropylene (19%) were the most abundant polymers. Polymer risk index analysis and pollution load index demonstrated that most of the sites ranked as safe. The potential ecological risks from single polymers and combined polymers showed minor risks posed by microplastics. The present study is the first step to focus on microplastic pollution in the Chenab River; it will help river managers to mitigate the microplastic pollution without compromising the ecological integrity of the river.
