- Assessment of microplastic contamination in Meretrix aurora from Punnakayal Estuary and Tuticorin Coast, Southeast India. S, Shelciya Patterson, Jamila India Bivalvia Water Pollutants, Chemical Estuaries Environmental Monitoring Animals Microplastics Geologic Sediments This study provides the first assessment of microplastics (MPs) pollution in the commercially important bivalve Meretrix aurora across estuarine and coastal environments on the southeast coast of India, comparing the Punnakayal Estuary (Site 1) and the Tuticorin Coast (Site 2). MPs concentrations were assessed in bivalve tissues (n = 75 per site), surface water (n = 3), and intertidal sediments (n = 3). Bivalve tissues were digested with KOH, while water and sediment samples underwent oxidative digestion combined with NaCl density separation. Results showed higher MPs loads in M. aurora from the urbanized Tuticorin Coast (0.81 ± 0.16 items/individual) compared to the Punnakayal Estuary (0.44 ± 0.12 items/individual), even though Tuticorin displayed lower MPs levels in water and sediment. Fibres dominated the ingested particles (> 60%), and nearly 80% were
