Effect of monsoon on microplastic bioavailability and ingestion by zooplankton in tropical coastal waters of Sabah
AI summary Read the abstract
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.
Plankton seasonality in tropical coastal waters is becoming more apparent as a result of monsoon-driven changes in environmental conditions, but research on the monsoonal variation of microplastics (MP) is still limited. We examined the monsoonal variation of MP in the water column and their ingestion by zooplankton in Sepanggar Bay, Sabah, Malaysia. MP concentrations were significantly higher during the Southwest monsoon whereas MP ingestions showed no monsoonal difference across major zooplankton taxa. Canonical Correspondence Analysis (CCA) and Generalized Additive Models (GAM) indicate that MP concentrations were driven by changes in rainfall and salinity while MP bioavailability to zooplankton was consistent regardless of monsoon. MP ingestion increased progressively up the planktonic food chain, and bioavailability of fibers and small-sized MP of high-density polymers to zooplankton was proportionately higher. Distinct changes in the MP concentration relative to the monsoons provide new insights into the seasonal variation of MP in tropical coastal ecosystems.

Researchers found seasonal variation in microplastic and zooplankton abundances around an oceanic island, with higher microplastic-to-zooplankton ratios in warmer months, suggesting the ecological risk to marine life from plastic ingestion fluctuates with environmental conditions such as temperature and precipitation.
Microplastics ingestion in zooplankton in tropical estuarine fronts of Terengganu, Malaysia
AI summary Read the abstract
Researchers surveyed microplastic ingestion by zooplankton in a tropical estuary in Terengganu, Malaysia, sampling across plume, front, and shelf zones during monsoon season. They found that zooplankton across all zones had ingested microplastics, with fibers being the most common type detected. The findings highlight the risk of microplastic trophic transfer through the marine food chain starting at the zooplankton level in productive tropical estuaries.
