摘要

Microplastics (MPs) are emerging contaminants with growing concerns about their accumulation and potential impacts on aquatic organisms. This study investigated the presence and impact of MPs in shrimp and water samples collected from three sluice gate harvest sites in Goa. MPs were found in the hepatopancreas of shrimp and water from all the sites, with St. Estevam site exhibiting the highest concentrations. Various shapes, sizes and polymers of MPs were identified with sizes ranging between 0.38 and 1168.18 μm. The CMPI highlighted minimum to average impacts. The PLI of all the sites fall under Category I indicating low hazard level. The BAF revealed low bioaccumulation (< 1). The EDI was calculated to be 0.74 ± 0.28 to 2.39 ± 0.92 particles/kg b.w/day. Although pollution indices showed low impact levels, these findings highlight the risk associated with consumption of MPs contaminated seafood.
