Plastic Contamination in Commercially Valuable Decapods Caught Near a Major Australian Urban Centre

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.

Effects of Microplastic Ingestion on Manila Clams

Microplastic Pollution in Shellfish Aquaculture: Occurrence, Impact, and Possible Remedies

AI summary · Read the abstract

This review documents widespread microplastic contamination in shellfish aquaculture, detailing how MPs enter farming systems and cause toxicological harm, behavioral changes, growth suppression, and reproductive failure in commercially farmed shellfish. Because shellfish are filter feeders consumed whole by humans, MP accumulation in these species creates a direct and concentrated pathway for human ingestion.

The Impact of Microplastics on Marine Copepods

AI summary · Read the abstract

Marine copepods, a foundational link in ocean food webs, ingest microplastics alongside natural prey, causing reduced feeding, reproductive impairment, and energy depletion that can cascade up through fish, seabirds, and marine mammals. Because copepods transfer energy from phytoplankton to higher trophic levels, their contamination with microplastics poses systemic risks to entire marine food chains.
