“…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.…”

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.

“…PP items are usually buoyant due to lower densities (0.83-0.91 gcm -3 ), regardless of their shape and size. This makes them readily transported by waters rather than being deposited in sediments (Wang et al 2018;Zhang et al 2020a). In addition, PP was frequently detected in previous MP investigations in the freshwater environments, such as 35.7% of total MPs detected in the Pearl River, China (Lin et al 2018), Manas River, China (30.6%), Qin River, China (39%), Antuã River, Portugal (29.4%), and Saigon River, Vietnam (4%) (Lahens et al 2018;Rodrigues et al 2018;Wang et al 2019;Zhang et al 2020b).…”

Scientific documentation on (Microplastics) MPs abundance in Malaysian waters is still limited and not fully understood. In this study, MPs occurrence in Sungai Dungun, Terengganu, Peninsular Malaysia was analysed. Sampling method was based on sieving 200 µm of bulk water to collect surface water samples from five sites in the vicinity of potential source for MP abundance. Characterisation of MPs was accomplished by gravimetric and digital image processing (for quantification and morphology categorisation), and chemical composition identified by attenuated total reflectance-Fourier infrared spectroscopy. The range concentration of MPs was 22.8 to 300.8 items/m 3 (mean 102.8 item/m 3). It was recorded that most of the MPs found were black and transparent. The most frequent morphotypes were fibres, followed by fragments. Polypropylene (C 3 H 6)n, polyacrylonitrile (C 3 H 3 N)n and rayon were the dominant polymertypes of MPs analysed in this work. Metals (Pb < As < Mn < Zn < Cu < Fe < Al) found within the MPs reported varied in terms of µg/mL. This study provided new insights into the understanding of MP levels in inland Malaysian freshwater environments.

“…First, the concept of marine ranching is defined in a variety of forms in different studies. For example, Zhang et al held the view that marine ranching is a type of mariculture industry that adopts scientific principles to cultivate and manage fishery resources [6]. Grant et al regarded that marine ranching involves releasing hatchlings into the wild.…”

Marine ranching plays an integral role in providing fishery resources. Given the critical importance of protecting the marine ecological system, the ecological security evaluation of marine ranching is significant. However, the existing research rarely involves marine ranching ecological security (MRES) evaluation and does not provide a complete evaluation index system. The purpose of the present study was to estimate MRES through several steps and evaluate it scientifically by fully considering the relationship between the factors. First, the evaluation index system was structured using the Driver-Pressure-State-Impact-Response (DPSIR) framework by following certain principles. Second, the study applied the Decision Making Trial and Evaluation Laboratory (DEMATEL) method and fuzzy comprehensive evaluation (FCE) method to assess MRES. Third, a case study of a marine ranching in the Shandong Province was discussed to demonstrate the applicability of the proposed method. This also illustrated the steps of the evaluation. In this case study, the result of the MRES evaluation was graded as excellent. The results demonstrate that using these methods to evaluate MRES can account for the complex relationships between the factors and the cognitive ability of the experts and thus integrate the experts’ information comprehensively, which adds to the credibility of the evaluation results.
