Towards Underwater Macroplastic Monitoring Using Echo Sounding [PDF]
Frontiers in Earth Science, 2021 Plastics originating from land are mainly transported to the oceans by rivers. The total plastic transport from land to seas remains uncertain because of difficulties in measuring and the lack of standard observation techniques.

Rapid Assessment of Floating Macroplastic Transport in the Rhine [PDF]
Frontiers in Marine Science, 2020 Most marine litter pollution is assumed to originate from land-based sources, entering the marine environment through rivers. To better understand and quantify the risk that plastic pollution poses on aquatic ecosystems, and to develop effective ...

Tracing macroplastics redistribution and fragmentation by tillage translocation [PDF]
Journal of Hazardous MaterialsSoil is polluted with plastic waste from macro to submicron level. Our understanding of macroplastics (> 5 mm) occurrence and behavior has remained comparatively elusive, mainly due to a lack of a tracing mechanism.

Macroplastic surface characteristics change during wind abrasion. [PDF]
Sci RepAbstract Mechanical abrasion is an important wind driven process which can degrade plastic litter on sandy beaches, desert environments and in agricultural settings. Wind-driven particle impacts can cause surface roughening and chemical changes and eventually complete fragmentation in high stress environments.

Underwater Macroplastic Detection Using Imaging Sonars [PDF]
Frontiers in Environmental Science, 2022 Plastic pollution in the ocean occurs mainly via riverine transport. In rivers, plastic is pervasive in sediments and in the water column. Monitoring of floating plastics in rivers is time consuming as it is usually collected using nets and classified by hand, or counted and classified visually.

Seasonality of riverine macroplastic transport [PDF]
Scientific Reports, 2019 AbstractMarine plastic pollution is an increasing environmental threat. Although it is assumed that most marine plastics are transported from land to the ocean through rivers, only limited data on riverine plastic transport exists. Recently, new methods have been introduced to characterize riverine plastics consistently through time and space.

Roadmap for long-term macroplastic monitoring in rivers [PDF]
Frontiers in Environmental Science, 2022 <p>Macroplastic pollution in and around rivers negatively impacts human livelihood, and aquatic ecosystems. Monitoring data are crucial for better understanding and quantifying this problem, and for the design of effective intervention strategies.
