The Pearl River delivers a large amount of plastic waste to the Estuary (PRE) and adjacent Northern South China Sea (NSCS) region each year. However, transport floating litter after release is difficult predict due complex hydrodynamic conditions caused by climate variability. A regional ocean circulation model coupled with Lagrangian particle tracking utilized in this study simulate distribution fate particles under influence El Niño - Southern Oscillation (ENSO) event. Simulations are conducted during all four seasons (spring, summer, fall, winter) typical Niño, La Niña, ENSO-neutral reveals that most remains within Lingding Bay before being transported westward counterclockwise over NSCS arriving at Qiongzhou Strait. After crossing Strait, debris carried Beibu Gulf, eventually coasts Vietnam Laos. ENSO warm (El Niño) cold (La Niña) phases disrupt patterns modulate runoff, thereby altering pathways grounding probabilities litter. During Niña years, spread wider area, travel longer distances, have lower beaching probabilities. Conversely, year, tend remain for durations, some entrained towards Hong Kong region. This underscores impact mode variability influencing sources, accumulation estuarine-coastal oceans, which will provide critical scientific insights pollution management PRE region, newly identified hotspot microplastic global oceans.

Microplastic (MP) transport patterns under open channel shear flow remain unclear. This study investigates the laws of MPs at various velocities, MP densities, sizes and concentrations in U-shaped experimental flume numerical based on Lattice Boltzmann Method (LBM). The results indicate that average horizontal particle velocity distances Polyvinyl chloride (PVC) Polystyrene (PS) particles increase with cross-sectional velocity, while vertical decreases it. total closely matches regardless variation size, density concentration. Formula-based analysis reveals acceleration spherical mainly depends size its consequent relative drag force term (RDFT) conditions a single type particles, but RDFT gravity (RGT) case concerning different types identical sizes. maximum PVC PS are both strongly correlated cross-section. correlation lowers concentration, is independent density. Our findings can provide reference for prevention control pollution rivers.
