An integrated dual-model framework for microplastic flux estimation and source apportionment in tropical island river systems
AI summary
This survey characterized beach litter composition and abundance in Lagos, Nigeria, documenting the types and quantities of plastic and non-plastic waste items along urban coastlines. The findings reflect waste management challenges in a rapidly urbanizing West African megacity and inform cleanup prioritization.

Tracing the Sources of Microplastics in Aquatic Environments: Current Knowledge of Sources Emission, Migration, and Traceability Models
AI summary Read the abstract
Researchers reviewed how microplastics enter aquatic environments from terrestrial and atmospheric sources, and how traceability models have evolved from subjective analysis to data-driven machine learning approaches that can identify pollution sources by learning relationships between microplastic characteristics and environmental variables.
Trailing the flow: source, fate and sink of microplastics in global rivers
AI summary Read the abstract
This review synthesized global research on microplastic pollution in rivers, covering sources, entry routes, and the key processes governing transport and transformation—including weathering, aggregation, sinking, and resuspension—along with ecotoxicological and socioeconomic impacts. Because rivers are the primary conduit transferring land-based microplastics to the ocean, understanding riverine dynamics is essential for designing effective interception strategies before contamination reaches marine food webs and human seafood supplies.
A drainage influence scoring framework explains seasonal microplastic patterns in a tropical urban catchment
AI summary Read the abstract
Researchers developed a drainage influence scoring framework to explain seasonal microplastic distribution in Kochi, India, finding that post-monsoon runoff significantly increased microplastic abundance in both water and sediment samples. The framework, which integrates upstream waste proximity, network connectivity, and urban density, showed a strong correlation with post-monsoon microplastic levels and can help prioritize drainage management strategies in tropical cities lacking detailed hydrological models.
Relative contributions of different local sources to riverborne microplastic in a mixed landuse area within a tropical catchment
AI summary Read the abstract
Researchers quantified the relative contributions of different land-use sources to riverborne microplastics in a tropical catchment, providing data to help prioritize pollution reduction measures for protecting human and ecological health.
Understanding the Microplastic ‘model’: Applications of Modelling to Track Microplastics in Aquatic Ecosystems
AI summary Read the abstract
Researchers reviewed mathematical modelling techniques used to track how microplastics move and spread through rivers, oceans, and other aquatic environments. Understanding these models is critical for predicting where plastic pollution accumulates and which ecosystems and communities face the greatest exposure risk.
