| Summary: | The widespread presence of microplastics in the ocean is a
significant threat to marine life and humans. A study was conducted to
investigate the extent of microplastic contamination in the coastal waters of
Langkawi and Penang, situated on the northern coast of Peninsular
Malaysia. Rock oysters (Saccostrea cucullata) were utilized as bioindicators
due to its availability in all sampling sites to evaluate microplastics,by
considering its abundance, types, polymer composition, and potential health
risks related to consumption. Soft tissues were digested with 10% KOH, and
the resulting microplastics were examined using a stereo microscope and
microplastics polymer were identified through ATR-FTIR. Kok Beach and
Penarak Beach exhibited notably higher microplastic abundance, mainly in
the form of filaments with predominant black and red colours. The most
common polymer types were cellulose triacetate (CTA) and
polycyclohexanedimethylene terephthalate (PCT). Hazard Quotient values,
indicating potential health risks from consuming S. cucullata, surpassed a
critical threshold at all locations. The study's findings suggest that it serves
as a fundamental reference for future research on microplastic contamination
in the islands along the northern coast of Peninsular Malaysia. |
