Microplastics in crabs in Hong Kong

Effects of Microplastic Ingestion on Manila Clams

Abundance and characteristics of microplastics in shellfish from Jiaozhou Bay, China

AI summary · Read the abstract

Researchers found microplastics in both wild and farmed oysters and clams from China's Jiaozhou Bay, estimating that average seafood consumption exposes Chinese consumers to over 1,200 microplastic particles per person per year through shellfish alone.

High Microplastic Contamination in Juvenile Tri-Spine Horseshoe Crabs: A Baseline Study of Nursery Habitats in Northern Beibu Gulf, China

AI summary · Read the abstract

All juvenile tri-spine horseshoe crabs sampled from China's Beibu Gulf contained microplastics in their gastrointestinal tracts at concentrations higher than most other marine benthic invertebrates, despite relatively low microplastic levels in the sediments themselves. This finding from a living-fossil species that spends years in coastal nursery habitats signals widespread microplastic ingestion risk for marine invertebrates and the ecosystems that depend on them.

Microplastics in Acetes shrimps from the southeastern coast of Bangladesh

AI summary · Read the abstract

Researchers analyzed microplastic contamination in two Acetes shrimp species from Bangladesh's southeastern coast, finding an average of 0.078–0.102 particles per shrimp, predominantly polyethylene and polypropylene fibers identified via ATR-FTIR. The findings demonstrate that even small zooplankton-level seafood consumed by millions carries microplastics, highlighting the dietary exposure pathway through marine food webs.

Microplastics in Biota

AI summary · Read the abstract

Microplastics have been detected in biota across marine, freshwater, and terrestrial ecosystems, demonstrating their ability to enter food webs at multiple trophic levels. Their omnipresence in living organisms raises concerns about bioaccumulation of both the plastic particles and the chemical additives and adsorbed pollutants they carry.
