Fish, bivalves and polychaeta: microplastics ingestion in Portuguese Coastal waters
AI summary
This 2016 review synthesized evidence on the effects of marine plastic pollution on organisms across taxa, covering ingestion, entanglement, and chemical contamination pathways. The review identified invertebrates, fish, seabirds, and marine mammals as particularly vulnerable and called for standardized effect thresholds to guide management.

Effects of the presence of microplastic particles in portuguese coastal waters and marine mussels
AI summary
Researchers conducted an anthropological and limnological study of the Kokosing River in Knox County, Ohio, documenting microplastic contamination alongside historical land use change. The study combined environmental science with community history to contextualize pollution patterns within the region's industrial and agricultural development.
Microplastics in Brazilian aquatic ecosystems and seafood: An updated review
AI summary Read the abstract
This review pulls together 100 studies to show that Brazil's rivers, bays, and coastal waters are widely contaminated with tiny plastic particles called microplastics, mostly from clothing fibers and packaging. Seafood like fish, shellfish, and crustaceans are absorbing these particles, sometimes in huge amounts, which raises real concerns for anyone eating fish from these waters. The bigger picture: plastic pollution levels swing a lot depending on rainfall and tourist seasons, and scientists still need better, more consistent testing methods to fully understand how much risk this poses to human health.
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.
Occurrence, bioaccumulation and ecological risk of aquaculture-derived microplastics in coastal waters
AI summary Read the abstract
Researchers reviewed microplastic contamination from aquaculture activities and found that fishing nets, foam buoys, and plastic packaging release large quantities of particles into coastal waters, with aquaculture-derived microplastics accounting for up to 99% of total microplastics at some sites. Cultured seafood consistently showed higher microplastic burdens than wild shellfish, highlighting aquaculture as a major but underestimated pollution source.
Microplastics in the Marine Ecosystems: Identification and Impacts
AI summary Read the abstract
Tiny plastic particles called microplastics, broken-down bits of everyday plastic waste, are showing up along India's coastlines, and this review paper rounds up what scientists have found so far. While research on their health effects is still catching up, these particles are known to persist in the environment and can enter the food chain through seafood, raising concerns about long-term exposure for coastal communities. The authors point out that India still needs a lot more research to fully understand how serious this problem is and what it means for people's health.
