Land-based plastic waste, carried to the sea through rivers, is considered a main source of
marine plastic pollution. However, most plastics that leak into the environment never make it …

Field data on plastic pollution is extremely limited in Southeast Asian rivers. Here we present
the first field measurements of plastic transport in the Mekong, based on a comprehensive …

Accumulation of microplastics in aquatic environments is an issue of emerging concern.
Initially, research focused on marine systems. However, recent studies also investigate the …

Microplastics, which are usually recognized as artificial polymer particles with a particle
size< 5 mm, have attracted much attention as new pollutants in recent years. Urban areas …

Urban areas are greatly affected by human activities that may result in the release of
microplastics. Fugitive release of microplastics is the unorganized discharge of microplastics …

Although studies on plastic concentrations mainly focus on the marine environment,
recently, an increasing number of studies point out environmental consequences in …

Stormwater runoff is often assumed to be an important pathway for microplastics from the
terrestrial to the marine environment, although few studies have attempted to quantify the …

As an important connection of terrestrial and marine ecosystems, rivers input multitudinous
(micro) plastics into the oceans. However, comparisons of field and estimated riverine inputs …

Plastic pollution in rivers threatens ecosystems, increases flood risk due to its accumulations
at hydraulic structures and its final emissions into the ocean threaten aquatic life, especially …

Abstract Study region The Santa Ana River middle reach, a small coastal urban catchment in
Southern California, USA experiences a Mediterranean climate and lowflows dominated by …
