Summary

Scientists fed microplastics to Pearl gentian grouper (a popular farmed fish) and found that the plastic particles caused real damage to their liver tissue and disrupted normal body functions at a cellular level. This matters because it shows microplastics can harm the seafood we eat, raising concerns about what happens further up the food chain, including in humans who consume fish regularly.

In this study, the toxic effects of microplastic ingestion on Pearl gentian grouper (Epinephelus fuscoguttatus♀ × E. lanceolatus♂) were investigated. Pearl gentian grouper with an average body weight of 64.85 ± 9.47 g were temporarily raised in glass aquariameasuring 70 cm × ...
