- Abstract:
- The reliable detection and analysis of microplastics (MPs) are crucial for the development of solutions to mitigate their potential impacts on the environment and human health. However, the removal of biological materials remains a significant challenge as MPs may be obscured by biological matter, complicating their isolation. This study optimized the digestion and extraction of MPs from milkfish parts using KOH combined with a dual-density separation involving NaCl and NaI solutions. Reference micropolymers were spiked into the fish parts to assess % recovery. Results revealed excellent digestion efficiencies and % recoveries (≈90%) in 10% KOH solution. The method was also applied to milkfish collected from Southeastern Mindanao, Philippines. Cellulose, PE, PP, PA, and PET polymers were detected. The average number of MPs found in the meat, fat, GIT, head, and gills were 1.2 ± 0.6, 2.4 ± 2.6, 0.5 ± 1.0, 2.6 ± 2.1 and 0.3 ± 1.0, respectively.
