Microplastics detection in milkfish (Chanos chanos) from selected aquaculture farm in the Philippines
AI summary Read the abstract
Researchers developed a method to detect tiny plastic particles in milkfish, improving removal of biological material that can hide them. Testing fish from a farm in the Philippines, they found several plastic types, including cellulose, PE, PP, PA and PET, with the most pieces found in the head and fat tissue.
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.

Assessment and characterization of microplastic contamination in milkfish (Chanos chanos) from marine aquaculture systems in the Philippines
AI summary Read the abstract
Researchers tested milkfish (a popular food fish) from fish farms in the Philippines and found tiny plastic particles, called microplastics, in their digestive systems—with some farm locations showing much higher contamination than others. Since these particles come from common plastic products like packaging and synthetic fabrics, this raises concerns about plastic exposure for people who eat farmed fish, though more research is needed to understand the actual health risks. The findings highlight the need for better pollution control in fish farming areas.
Microplastic ingestion by adult milkfish Chanos chanos (Forsskål, 1775) in aquaculture system: The case of Butuan Bay, Philippines
AI summary Read the abstract
Researchers examined farmed milkfish from aquaculture cages in Butuan Bay, Philippines, and found microplastics in 97% of the fish sampled. The dominant particle types were fibers and fragments, with colors and polymer types matching common plastic packaging and fishing materials. The study raises concerns about microplastic contamination entering the human food supply through aquaculture in coastal areas with high plastic pollution.
