Abstract

Microplastic contamination in marine ecosystems threatens food security and human health. This study analyzed characteristics, abundance, and polymer composition of microplastics in round scad (Decapterus russelli) from Rembang waters and evaluated toxicological risks through Polymer Hazard Index (PHI). Fish samples were collected from three locations at village Banggi, Kragan, and Dasun with five individuals per location. Microplastics were isolated from muscle and gastrointestinal tract using 30% H2O2 digestion, characterized by shape and color, and identified for polymer composition using FTIR spectroscopy. Results showed microplastics detected in 100% samples with fiber predominance in muscle and films in gastrointestinal tract. Black color dominated in muscle (64.91%) and transparent in gastrointestinal tract (48.30%). Abundance in muscle differed significantly among locations (Kruskal-Wallis test: H=9.448; p=0.009) with Banggi highest (3.20±1.09 particles/gram), followed by Dasun (1.43±0.53 particles/gram) and Kragan (1.26±0.74 particles/gram). Abundance in gastrointestinal tract showed no significant difference (H=0.562; p=0.755) ranging from 37.51-47.85 particles/gram. FTIR identified polyethylene (PE), polyamide/nylon (PA), polystyrene (PS), polycarbonate (PC), polyvinyl chloride (PVC), and polyacetal (POM). Highest PHI value in Banggi muscle (197.21; Very High Category) due to PC and POM predominance. Average PHI of muscle (81.34) was higher than gastrointestinal tract (19.84), indicating selective translocation of hazardous polymers. Presence of PVC (hazard score 10,000) and PC (hazard score 1,000) raises serious toxicological concerns. Comprehensive mitigation strategies including regulation strengthening, routine monitoring, and education are required to protect seafood safety.
