ClearEffect of monsoon on microplastic bioavailability and ingestion by zooplankton in tropical coastal waters of Sabah
Researchers measured seasonal variation in microplastic concentrations and zooplankton ingestion of microplastics in Sepanggar Bay, Malaysia, finding that monsoon-driven environmental changes significantly affect both microplastic bioavailability and uptake by zooplankton in tropical coastal waters.
Unveiling Microplastic Abundance and Distribution in an Oceanic Island: Offshore Depository or Local Pollution Indicator
Microplastic abundance and distribution were documented across surface waters and sediments of an oceanic island, with findings indicating both local land-based pollution and ocean gyre-driven deposition of particles from distant sources.
Zooplankton exposure to microplastics at the global scale: Influence of vertical distribution and seasonality
Researchers compiled a global dataset of variables used to model zooplankton exposure to microplastics, incorporating vertical distribution and seasonality factors to better characterize how different zooplankton depth preferences and seasonal migration patterns influence the degree of microplastic contact across ocean regions.

Researchers evaluated microplastic bioavailability and bioconcentration across seven zooplankton taxonomic groups in a Caribbean Marine Protected Area, finding microplastic ingestion during two contrasting hydroclimate seasons using oblique net tows at twelve stations.
Spatial and temporal variation of macro-, meso- and microplastic abundance on a remote coral island of the Maldives, Indian Ocean
Researchers conducted daily sampling of plastic debris on a remote Maldives island over seven consecutive days and found high spatial and temporal variability in plastic abundance despite the island's remoteness, warning that single-snapshot surveys can produce biased estimates and that future monitoring programs must account for natural fluctuations in deposition.
Zooplankton exposure to microplastics at global scale: Influence of vertical distribution and seasonality
Researchers used a global ocean model to assess zooplankton exposure to microplastics, finding that exposure varies significantly with depth, season, and zooplankton vertical migration patterns, with highest concentrations in subtropical gyres and near coastal pollution sources.
Seasonal-Dial Shifts of Ichthyoplankton Assemblages and Plastic Debris around an Equatorial Atlantic Archipelago
A study near a remote Atlantic archipelago found plastic debris in ocean waters year-round regardless of season, while fish larvae communities shifted with the dry and wet seasons. The consistent presence of plastic debris even in this remote equatorial location underscores how widespread ocean plastic pollution has become.
Ingestion of Microplastics by Zooplankton in the Northeast Pacific Ocean
Researchers collected zooplankton from the northeast Pacific Ocean and found microplastics ingested by multiple species, demonstrating that microplastic uptake occurs throughout the open ocean zooplankton community far from coastlines.
Seasonal characteristics of microplastics ingested by copepods in Jiaozhou Bay, the Yellow Sea
Researchers investigated seasonal variation in microplastics ingested by copepods in Jiaozhou Bay, China, finding that microplastic abundance in zooplankton varied significantly across seasons and was correlated with key environmental factors including temperature and chlorophyll concentration.
Urbanization Impacts on Microplastic in Benthic Organisms and Sediment of Small Islands
Researchers investigated how urbanisation on small islands in Indonesia affects microplastic contamination levels in benthic organisms and sediments, examining the impact of land use conversions from pristine ecosystems to settlements and tourism facilities.
Spatial distribution of microplastics around an inhabited coral island in the Maldives, Indian Ocean
Researchers investigated microplastic accumulation across fore reef, reef flat, and beach sediment environments surrounding a small inhabited coral island in the Maldives, finding 1,244 individual microplastic pieces across 22 sampling sites. The study reveals that even remote inhabited islands in the Indian Ocean show significant microplastic contamination, with spatial distribution patterns reflecting local hydrodynamics and human activities.
Influence of monsoon seasonality and tidal cycle on microplastics presence and distribution in the Upper Gulf of Thailand
Researchers surveyed microplastic pollution around Si Chang Island in the Gulf of Thailand across different monsoon seasons and found that seasonal weather patterns strongly influence microplastic abundance and distribution. Evidence suggests that UV exposure during dry seasons fragments plastic waste on land, which is then washed into the ocean by heavy rains during the wet season. The findings highlight how tropical climate cycles drive microplastic contamination in Southeast Asian coral reef areas.
Microplastic ingestion in marine mesozooplankton species associated with functional feeding traits
This study examined microplastic ingestion in marine mesozooplankton species with different functional traits, finding that feeding mode, body size, and habitat use are key predictors of plastic uptake across zooplankton communities.
Ecology of mesozooplankton in a subtropical coastal lagoon: composition, spatial distribution and interactions with microplastic pollution
Researchers studied mesozooplankton ecology in a subtropical coastal lagoon, examining community composition, spatial distribution, and interactions with microplastic pollution to understand how plastic contamination affects zooplankton dynamics in coastal environments.
Screening for microplastic particles in plankton samples: How to integrate marine litter assessment into existing monitoring programs?
Researchers monitored microplastic abundance in zooplankton net samples, finding 100–10,000 particles per cubic meter with no consistent seasonal or depth pattern. The study proposes that existing zooplankton monitoring programs could be adapted to simultaneously track microplastic pollution at relatively low additional cost.

Researchers investigated microplastic abundance and types relative to plankton populations in Benoa Bay, Bali, finding that microplastics resembling food sources pose ingestion risks to marine organisms that can propagate through the food chain via bioaccumulation.
Pervasive Microplastics and Zooplankton Abundance in Middle East Region of Java North Sea Indonesia: Spatio-Temporal of an Oceanic System
Researchers conducted spatio-temporal sampling of microplastics from water columns and zooplankton in the Middle East region of the Java North Sea (Jepara and Rembang, Indonesia) from February to August 2024, characterizing microplastic color, shape, size, and abundance by microscopy to assess threats to marine food webs through planktivorous organism ingestion.
Annual variation in neustonic micro- and meso-plastic particles and zooplankton in the Bay of Calvi (Mediterranean–Corsica)

Zooplankton exposure to microplastic contamination in a estuarine plume-influenced region, in Northeast Brazil
Researchers examined microplastic contamination in estuarine plume waters off the coast of northeastern Brazil and its relationship with zooplankton. The study found significantly higher microplastic abundance during the high rainfall season, with fibers and fragments being the dominant types, and elevated concentrations in river plume areas compared to reef-adjacent waters, indicating land-based sources as major contributors.
Neustonic microplastic and zooplankton in the North Western Mediterranean Sea
Researchers measured microplastic and zooplankton abundance in surface waters of the northwestern Mediterranean Sea and found plastics at 90% of stations sampled, with microplastic densities comparable to zooplankton in some areas.
