• Ecological patterns of trace and essential metal bioaccumulation in marine fish from the Gulf of California, Mexico (2026) · Frontiers in Marine Science · doi

  The study identifies a gap in understanding the bioaccumulation patterns of trace and essential metals in marine fishes. There is a need to assess the influence of feeding ecology and metabolic capacity on metal bioaccumulation. The research gap includes the lack of data on metal concentrations in fish from the Gulf of California, Mexico.

• Occurrence of Microplastics in Commercial Fish Species in Nigeria: A Case Study of Lower Usuma Dam and Jabi Lake, Federal Capital Territory, Abuja, Nigeria (2026) · FUDMA Journal of Sciences · doi

  None of these studies examine dried-fish products specifically; all microplastic research focuses on fresh or market-purchased whole fish. The processing, drying, and storage of fish may concentrate, reduce, or alter microplastic profiles compared to fresh fish, yet no study traces microplastics through the drying chain or compares fresh versus dried forms of the same species.

• Organ-specific bioaccumulation of trace elements in commercial marine finfish from the South Andaman Islands and associated human health risk assessment (2026) · Discover Oceans · doi

  Across this set, heavy-metal bioaccumulation in fish is evaluated only in fresh or live-caught specimens from marine and freshwater ecosystems; no study measures trace-element concentrations in dried-fish products, where moisture loss and microbial/chemical degradation during drying may alter bioavailability and residue levels relative to fresh tissue.

• Organ-specific bioaccumulation of trace elements in commercial marine finfish from the South Andaman Islands and associated human health risk assessment (2026) · Discover Oceans · doi

  Heavy-metal and pesticide studies in this set focus on single or few fish species per location; none systematically compares contamination profiles across multiple dried-fish species (e.g., anchovy, herring, small pelagics, catfish, tilapia) from the same polluted region to identify species-specific bioaccumulation or dietary exposure pathways relevant to subsistence and commercial dried-fish consumers.
