Dispersal and transport of microplastic particles under different flow conditions in riverine ecosystem

Xiaorong Lu et al.

Summary: This study investigated the dispersal and transport processes of microplastic particles in river ecosystems using a combination of particle tracking and hydrodynamic modeling. The results showed that rainfall intensity and water velocity significantly affected the transport of microplastics in rivers. Higher suspension concentration and longer migration distances were observed during high flow periods. The density of microplastic particles also influenced their mobility and deposition in water.

Spatial and seasonal distribution of microplastics in various environmental compartments around Sishili Bay of North Yellow Sea, China

Yanfang Li et al.

Summary: Microplastic pollution in the marine environment is strongly influenced by human activities in coastal areas. Seasonal samples collected from various environmental contexts exhibited different abundance and shape variations. The common microplastic shapes in water and sediment were fibers and fragments, while foams were present seasonally on the beach sand. The results indicate that coastal areas are particularly vulnerable to human activities such as aquaculture and fisheries. Further investigations are necessary to fully understand the distribution of microplastics in the coastal region.

Effect of the first-flush phenomenon on the quantification of microplastics in rainwater

Taegu Do et al.

Summary: Precipitation of airborne microplastics by rainfall is a major pathway for their transport from land to marine environments. However, studies directly investigating microplastics in rainwater are scarce. This study demonstrated a high-frequency and direct rainwater sampling method considering the first-flush effect. The abundance of microplastics varied with the size of rainwater collector, sampling time, and duration. Our methodology, presenting microplastics concentration versus time curves based on high-frequency sampling, allows for easy comparison between similar rainfall studies.

Real-time variabilities in microplastic abundance and characteristics of urban surface runoff and sewer overflow in wet weather as impacted by land use and storm factors

Xiaonan Sun et al.

Summary: An in-field investigation was conducted in six central urban drainage systems along Suzhou Creek in Shanghai, China to study the real-time dynamic changes in microplastic abundance and characteristics in urban surface runoff (USR) and wet weather flows (WWF). The study found correlations between environmental factors and microplastic abundance, especially the polymer type, in USR and WWF. It was also observed that land use had a minimal impact on the size and shape of microplastics. The results provide valuable insights for the mitigation of emerging pollutants and the enhancement of stormwater management strategies.

Investigation of dynamic change in microplastics vertical distribution patterns: The seasonal effect on vertical distribution

Cristele Chevalier et al.

Summary: This study examines the variability of microplastics vertical distributions in the oceanic water column. Through targeted sampling in the Bay of Marseille and numerical simulation with realistic physical forcings, three categories of microplastics are identified: settling, buoyant, and winter neutrally-buoyant microplastics. Buoyant microplastics are mainly concentrated at the surface, but can mix throughout the water column during episodes of strong winds and no water stratification, leading to an underestimation of buoyant microplastics in surface sampling. Settling microplastics are mainly found at the bottom, but can occasionally reach the surface under specific mixing conditions. Winter neutrally-buoyant microplastics are more evenly dispersed during the winter but are located beneath the stratified layers in summer.

Physical processes matters! Recommendations for sampling microplastics in estuarine waters based on hydrodynamics

Sophie Defontaine et al.

Summary: Monitoring microplastics in estuarine waters is crucial for understanding their fate and developing mitigation strategies. However, existing protocols may not be suitable for estuarine environments due to complex hydrodynamics. This note reviews sampling methods and proposes recommendations for capturing a representative picture of microplastic pollution, emphasizing the urgent need for standardized methods adaptable to different estuarine systems.

Microplastics in the riverine environment: Meta-analysis and quality criteria for developing robust field sampling procedures

J. Lofty et al.

Summary: Current sampling approaches for quantifying microplastics (MP) in riverine systems are unstandardized and lack important river properties, hindering our understanding of MP behavior. In this study, we reviewed 36 field-based river studies and found that most studies did not meet quality criteria and omitted critical information. However, spatial information and sampling equipment were adequately documented in many studies. A standardized sampling approach is proposed to improve our understanding of MP behavior and transport in freshwater environments. Additionally, a meta-analysis revealed high variability in MP concentrations and identified commonly reported polymers and shapes in river studies.

An innovative approach for microplastic sampling in all surface water bodies using an aquatic drone

Gabriel Pasquier et al.

Summary: The lack of a standardized method to evaluate microplastic pollution in different aquatic environments worldwide is a challenge that needs to be addressed by the scientific community. To overcome this, researchers adapted an aquatic drone, named Jellyfishbot, to sample microplastics and compared its performance with the widely used Manta net method. The results showed that the aquatic drone provided similar results in terms of microplastic abundance, shapes, and colors, while offering better reproducibility and more accurate sampling of surface waters. This new sampling method combines the advantages of Manta net sampling with pump filtration and grab sampling, and has the potential to become a standardized approach for evaluating microplastic pollution levels.

Widespread occurrence of microplastics in marine bays with diverse drivers and environmental risk

Dong Liu et al.

Summary: Microplastic contamination in marine bays has been widely studied, but their distribution, sedimentation, morphology, and risk at a regional scale are not well understood. In this study, a microplastic dataset of 649 samples from 24 bays was compiled using a data mining framework. The study found that microplastic abundance varied across different bays, with higher concentrations in East Asian bays. The abundance was driven by river plastic emissions, aquaculture production, and hydrodynamic conditions. The dominant shape and polymer of microplastics in sediment were fiber and polypropylene, respectively. Environmental risk assessment identified Asian bays as potential high-risk areas. The study highlights the importance of a unified methodology for sampling, pretreatment, and identification to enhance our knowledge on microplastic distribution and risk in marine bays.

Seasonal variation and complex analysis of microplastic distribution in different WWTP treatment stages in Lithuania

Ieva Uoginte et al.

Summary: Industrial wastewater, domestic wastewater, and stormwater are the sources of microplastics in wastewater treatment plants. This study collected samples from different treatment stages to evaluate the efficiency of a municipal wastewater treatment plant in removing microplastics. Results showed that microplastic particles were present in all samples, with the highest concentration in influent and the lowest in effluent and sludge. The most common microplastics were polyethylene terephthalate (PET), polystyrene (PS), and polypropylene (PP). Long-term monitoring and quantification of microplastics are necessary to accurately assess their pollution in wastewater treatment plants.

Microplastic trapping in dam reservoirs driven by complex hydrosedimentary processes (Villerest Reservoir, Loire River, France)

N. N. Phuong et al.

Summary: This study investigates the distribution of microplastic pollution in sediments of the Villerest reservoir. The results show that the section with fine-grained sediments has significantly higher levels of microplastics compared to the section with coarse-grained sediments. The study also finds that the polymer diversity is higher in fine-grained sediments. This research contributes to a better understanding of the role of hydrosedimentary processes in microplastic distribution and provides valuable insights for sediment management operations.
