“…Fifty percent of MPs in this study were ≤1.5 mm and 84.5% were ≤3.0 mm. Longer and larger MPs may pose more of a toxicological risk to biota [74], while smaller MPs are easily bioaccumulated and transferred across trophic levels [5,75]. Heavier MPs will sink and accumulate in the substrate [76,77], as will aged MPs after accumulating biofouling [78].…”

“…Microplastics (MPs) are defined as plastic pieces < 5 mm. In aquatic environments, MPs are effectively bioaccumulated across trophic levels due to their small size and buoyancy [3][4][5][6]. Aquatic organisms known to accumulate MPs include oysters [7], fulmars [8,9], osprey [10], amphibians [11], mussels [12,13], whales [14,15], sea turtles [16,17], and fish [18][19][20][21].…”

Stormwater outfalls are frequently listed as sources of microplastic (MP) contamination into aquatic systems. To date, few studies have been undertaken to determine if stormwater outfalls are MP hotspots in estuaries. This study compared the surface waters adjacent to and at least one kilometer away from stormwater outfalls of a subtropical estuarine system: the Indian River Lagoon (IRL) on the east coast of Florida, USA. Citizen scientists collected water samples monthly for 12 months from stormwater outfalls (n = 24) and control sites (n = 6). Overall, 958 MPs were identified from 1800 L of water, with the most found in the fall months during hurricane season. Stormwater outfalls (mean: 0.53 MP/L) were found to discharge smaller MPs (GLM: p = 0.0008) in significantly higher amounts compared to control sites (GLM: p = 0.02), documenting stormwater as a point-source pollutant in this system. Two types of stormwater outfalls drained into the IRL—closed culverts and open drainage channels—with no difference in MP abundances between the two (GLM: p = 0.60). Microfibers dominated collections (89%). Using ATR-FTIR for polymer identification, 80% of the materials found were plastic; polypropylene (29%), polyethylene (18%), and polyethylene terephthalate (18%) were the most abundant polymers found.

“…A single plastic teabag at brewing temperature (95 °C) was found to release 11.6 billion microplastics and 3.1 billion nanoplastics (NPs) into a single cup of tea . Various kinds of vegetables, fruits, and seafood have been responsible for the trophic transfer of microplastics to humans. ,− …”

Plastic cutting boards are a potentially significant source of microplastics in human food. Thus, we investigated the impact of chopping styles and board materials on microplastics released during chopping. As chopping progressed, the effects of chopping styles on microplastic release became evident. The mass and number of microplastics released from polypropylene chopping boards were greater than polyethylene by 5−60% and 14−71%, respectively. Chopping on polyethylene boards was associated with a greater release of microplastics with a vegetable (i.e., carrots) than chopping without carrots. Microplastics showed a broad, bottom-skewed normal distribution, dominated by <100 μm spherical-shaped microplastics. Based on our assumptions, we estimated a per-person annual exposure of 7.4−50.7 g of microplastics from a polyethylene chopping board and 49.5 g of microplastics from a polypropylene chopping board. We further estimated that a person could be exposed to 14.5 to 71.9 million polyethylene microplastics annually, compared to 79.4 million polypropylene microplastics from chopping boards. The preliminary toxicity study of the polyethylene microplastics did not show adverse effects on the viability of mouse fibroblast cells for 72 h. This study identifies plastic chopping boards as a substantial source of microplastics in human food, which requires careful attention.

Peningkatan aktivitas antropogenik telah menyebabkan intrusi polutan ke perairan. Polutan mikroplastik berukuran 5 mm terbentuk karena proses degradasi plastik yang berukuran lebih besar. Partikel mikroplastik di perairan dapat menimbulkan dampak buruk terhadap biota perairan terutama biota bentik yaitu kerang A. granosa. Keberadaan kerang A. granosa di Estuari Sungai Musi dapat dijadikan indikator keberadaan mikroplastik di perairan. Sampel A. granosa dikelompokkan berdasarkan ukuran main catch dan by-catch sesuai tangkapan nelayan lokal. Ekstraksi mikroplastik pada kerang A. granosa menggunakan metode ekstraksi basa larutan KOH 10%. Sampel A. granosa yang diekstraksi berupa saluran pencernaan. Perbandingan berat sampel dan larutan KOH 10% yaitu 1: 3 (b/v). Hasil kepadatan mikroplastik menunjukkan kepadatan yang lebih tinggi pada ukuran sampel yang lebih besar. Karakteristik jenis dan warna mikroplastik sebanyak 4 jenis dan 6 kelompok warna. Jenis mikroplastik yang teridentifikasi terdiri dari film, pelet, fragmen, dan fiber, sementara kelompok warna mikroplastik terdiri dari hitam, kuning, merah, hijau, putih, dan transparan. Berdasarkan karakteristik tersebut, kerang A. granosa teridentifikasi sebagai biota indikator terhadap pencemaran mikroplastik di perairan Estuari Sungai Musi melalui metode ekstraksi larutan KOH 10%.
