Mud and organic content are strongly correlated with microplastic contamination in a meandering riverbed

Communications Earth & Environment, Год журнала: 2024, Номер 5(1)

Опубликована: Авг. 22, 2024

The scale of microplastic pollution in river sediments is gradually being elucidated through an increasing number large-scale studies. Nevertheless, distribution within a riverbed – crucial aspect for quantification remains poorly understood. Here we evaluate the meandering River Lys, Belgium, how concentration varies between different sedimentary environments riverbed. We find that abundance about order magnitude higher towards riverbanks compared to thalweg, corresponding with hydrodynamics. Moreover, organic-matter and mud content are robust predictors concentrations, apart from outer bends, where erosion into organic-rich, muddy floodplain inhibits deposition. These results increase our understanding at small scale. They element guide future sampling efforts across diverse systems, paving way normalization better microplastics trapped by other aquatic environments. Microplastic deposition rivers near banks, well correlated organic matter content, according direct measurements campaign Belgium.

Spatial and seasonal abundance and characteristics of microplastics along the Red River to the Gulf of Tonkin, Vietnam

The Science of The Total Environment, Год журнала: 2024, Номер 957, С. 177778 - 177778

Опубликована: Ноя. 30, 2024

This study aimed to examine the occurrence of microplastics in surface water and sediment samples collected from Hanoi Ba Lat estuary along Red River, second-largest river Vietnam (surface area: 156,451 km2). 21 stations were sampled during dry (March 2023) rainy (September seasons. The analytical procedure involved: digestion with hydrogen peroxide, flotation potassium carbonate, overflow filtration. filters analyzed by microscopy (Nikon SMZ645) describe shapes colors μ-FTIR (PerkinElmer Spotlight 400) determine polymer types abundances. Results showed that microplastic quantities throughout ranged 10 203 items.m-3 653 8069 990 21,610 items.kg-1 dried weight (d.w.) seasons, respectively. MPs classified into two main shape groups: fiber fragment, fibers being predominant, representing 82.0 % 75.5 sediment, primary identified white/transparent, black, blue. Particles between 13 200 μm predominant size class, accounting for 64.1 72.4 Polyethylene, polypropylene, polyethylene terephthalate polymers, 71.5 72.2 as revealed analyses. Overall, MP pollution load is moderate, but type particles detected represents a high dangerous risk, resulting very potential ecological risk on river.

Freshwater microplastics governance and sustainable development: Pollution status, interactions, policies, and prospective studies

Desalination and Water Treatment, Год журнала: 2024, Номер 320, С. 100704 - 100704

Опубликована: Авг. 12, 2024

Concerns about microplastics are increasing due to their potential threats ecosystems and human health. Current research focuses mainly on marine environments, with insufficient study freshwater microplastics. This reviews the status, policies, interactions of over past 20 years proposes feasible policy suggestions. The widespread presence in poses risks aquatic organisms impacts health through food chain. In response this issue, various countries organizations have proposed focusing reducing sources, recycling substitution, monitoring evaluation, pollution control. spatiotemporal distribution varies, pollutants involve mechanisms such as hydrophobic electrostatic interactions, hydrogen bonding, π-π surface complexation, van der Waals forces. These findings provide a theoretical basis for future governance, monitoring, effective formulation sustainable management
