Microplastics impact assessment on Langkawi Island off Strait of Malacca waters using rock Oyster as bioindicator

Microplastics (MPs) assessment was conducted in five sites along Langkawi Island off Strait of Malacca coastal shoreline. In this paper, an improved protocol digestion for soft tissue and multi-steps MPs identification had been developed the polymer are performed by ATR-FTIR. Number found varied from 0.47 to 1.0 items/w. weight (g) 0.73 1.47 items/individual rock oysters. The composition dominated threadlike shapes color black, blue, red, grey, yellow. Size ranging between 500 1000 µm based on analysis, polymers identified PVDF, PP PET. overall abundancy bivalve is 1.46 ± 0.007 (g), however, it still necessary do periodic monitoring tourists’ attraction island that well-known seafood.
