Microplastics in Food: A Review on Analytical Methods and Challenges

“…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.…”

Microplásticos en peces marinos de importancia económica en Lima, Perú

“…Estas partículas resultan de la liberación directa de plásticos, de pellets de diferentes tamaños utilizados para diversos fines en productos de cuidado personal, agentes de limpieza, cosméticos, etc. (Barboza et al, 2019;Bucol et al, 2020). Los MP pueden ser productos de un proceso de fragmentación lenta generado por energías mecánicas y radiación solar que ocurren en el ambiente (Auta et al, 2017;Pozo et al, 2019).…”

“…Los MP pueden ser productos de un proceso de fragmentación lenta generado por energías mecánicas y radiación solar que ocurren en el ambiente (Auta et al, 2017;Pozo et al, 2019). Durante la degradación del MP, se pueden liberar sustancias químicas que generan un impacto negativo en los organismos y ecosistemas al cual están expuestos (Royer et al, 2018;Bucol et al, 2020).…”
