Trophic transfer of CeO₂ nanoparticles from clamworm to juvenile turbot and related changes in fish flesh quality.

ABSTRACT: Engineered nanoparticles (ENPs) accumulate in marine sediments and exhibit adverse effects on benthic organisms. However, the effect of ENPs on marine benthic food chains is largely unknown. Herein, we investigated the trophic transfer and transformation of CeO₂ ENPs within a simulated marine benthic food chain from clamworm (Perinereis aibuhitensis) to turbot (Scophthalmus maximus), as well as their effects on fish flesh quality. The results showed that Ce contents in turbot increased with the accumulation of CeO₂ ENPs in clamworm, but no biomagnification of CeO₂ ENPs occurred along this food chain. During trophic transfer, CeO₂ ENPs in turbot experienced transformation from Ce(IV) to Ce(III). Importantly, CeO₂ ENPs accu
