Efficiency assessment of microplastic extraction from green mussel \(\textit{Perna viridis}\) Linnaeus

Microplastics with particle size less than 5 mm are becoming a raising global environmental crisis. These pollutants were found from the poles to equator, in continental shelves, coasts and oceans, moreover, they have also been identified water columns, sediments even variety of organisms. The majority microplastics that ended up oceans originate land. Due their small size, easily accumulated food chain, causing harmful effects on organisms human health. bivalves especially caught interest scientific researchers because direct contact through filter-feeding habit. Therefore, it is essential develop methods determine presence these identify source. This study evaluated efficiency extracting tissues green mussels (Perna viridis) using KOH 10% solution digest KI 50% as separating solution. Mussel soft tissue samples spiked five different types microplastics: polystyrene (PS), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polypropylene (PP), high-density (HDPE) treated some mussel species was investigated farming areas Giao Thuy, Nam Dinh province, Thi Nai, Quy Nhon, Binh province Hue city, Thua Thien province. research results showed high microplastic extraction recovery range 76% 97%. Microplastic concentration obtained all variates 1.0 ± 0.1 particles/g 1.7 0.6 particles/g, which fiber predominated. sizes < 1,000 µm 1,000–2,000 µm, make 74.15–82.32% 9.76–14.71%, respectively. Purple dominant among samples. proved isolate suitable approach can be used monitoring studies pollution bivalves.
