This study investigated the extent of microplastic (MP) contamination in sediment and surface water from one largest shipbreaking yards along Bay Bengal coast. A total 48 samples (24 each water) were collected analyzed to assess MP abundance, polymer characteristics, sources, associated potential ecological risks. MPs extracted, identified using microscopy FTIR spectroscopy, classified by type, color, composition. concentrations averaged 73.54 ± 8.61 items/kg 218.56 19.12 items/m3 water, with fibers being dominant morphology (87.8-92.1 % sediment, 91.5-100 water). Stations close intensive operations exhibited significantly higher abundances. Polymer characterization revealed PET as comprising 37.5 25 followed PS (25 both matrices) PP (12.5 sediment). Ecological risk assessments moderate considerable levels. Pollution Load Index (PLI) values ranged 1.02 1.433 1.02-1.68 water. Polymeric Hazard (PHI) reached maximum at 254.37 (sediment) 265.68 (water), corresponding Risk (ERI) reaching 312.88 433.06, respectively. S6 S3, located near areas activity, highest These findings emphasized urgent need for regulatory intervention improved waste management.
