Comprehensive Effects of Temperature, Salinity,and Current Velocity on the MicroplasticAbundance in Offshore Area
Summary
Researchers analyzed how temperature, salinity, and current velocity influence microplastic abundance in three offshore areas — the East China Sea, Java Island, and Tampa Bay — using multiple linear regression. Current velocity was identified as the most important hydrological factor driving microplastic accumulation or dispersal.
Three offshore areas including the East China Sea, Java Island in Indonesia, and Tampa Bay in the USA were selected as the survey regions. The effects of hydrological conditions on the abundance of microplastic in the survey marine regions were analyzed using the multiple linear regression analysis in this work. The regression models were constructed with the seawater temperature, salinity, and current velocity as independent variables. The models showed that current velocity was the most important factor that affected the accumulation or diffusion of microplastic. Seawater temperature and salinity also affected microplastic abundance by affecting the movement and density of seawater. It is feasible to establish a regression model of microplastic abundance through hydrological data in offshore areas to analyze and predict the migration and accumulation characteristics of microplastic. The interaction of hydrological factors determined the abundance of marine microplastic.

Dynamic distribution of microplastics in mangrove sediments in Beibu Gulf, South China: Implications of tidal current velocity and tidal range
Researchers examined how tidal current velocity and tidal range influence the distribution of microplastics in mangrove sediments in Beibu Gulf, South China, finding strong linear relationships between current velocity and microplastic content during both flood and ebb tides. Microplastic concentrations increased from the seaward to landward boundary, with tidal current velocity -- but not tidal range -- significantly predicting their accumulation rates.
Testing the factors controlling the numbers of microplastics on beaches along the western Gulf of Thailand
Researchers measured microplastic concentrations on beaches along the western Gulf of Thailand and applied statistical models to link abundance patterns to ocean surface currents and land-based pollution sources, finding that current direction and proximity to riverine inputs were the strongest predictors of beach MP levels.
Can microplastics in offshore waters reflect plastic emissions from coastal regions?
Researchers found a significant negative correlation between coastal plastic discharge amounts and offshore microplastic abundance in Chinese waters, indicating that hydrodynamic conditions rather than proximity to pollution sources primarily determine microplastic distribution.
Analysing the influence of hydrodynamic and sedimentary factors on the microplastic distribution in the Ashtamudi estuary, India
Microplastic abundance in the Ashtamudi estuary in India ranged from 3.2 to 53 items/L, with highest concentrations near river-sea confluences; the study found microplastic distribution inversely correlated with current velocity and directly with suspended sediment concentration, enabling a predictive non-linear transport model.
Modeling the fate of microplastics in the Sengkarang Estuary, Pekalongan City, Central Java, Indonesia
Researchers measured microplastic concentrations in water and sediment at the mouth of the Sengkarang River in Indonesia and built a hydrodynamic model to track how tidal currents, wind, and river flow distribute the particles. Microplastics were highest in coastal waters and mangrove sediments, with tides and currents driving horizontal transport and concentrating particles in biologically sensitive habitats. The modeling approach offers a practical framework for predicting where microplastics accumulate and informing pollution management in river-to-sea systems.
