An increasing global problem is the buildup of improperly handled plastic garbage in environment. One biggest environmental issues facing aquatic ecosystems today contamination from bulk plastics and detritus. Specifically, microplastics (MPs) nanoplastics, which are small-scale waste, now main causes pollution freshwater marine environments. On other hand, systems acknowledged as one major hazards our world. Currently, concerns have been raised regarding breakdown products into micro nanosized particles, because ineffective waste management. To prioritize regions for mitigation policy implementation, it critical to pinpoint precise MPs’ transport mechanisms locations where trash created. In order show historical contemporary circumstances well forecasts scenarios management until 2060, we used continent-level data on This study, finally, presents a potential future scenario estimates destiny, transport, occurrence habitats, highlighting different factors that trigger MPs water necessity rational waste.

Concerns regarding plastic pollution, especially microplastics, have increased, as they can be present in different environmental compartments, including estuarine areas and saltmarshes. Although saltmarshes are highly vulnerable to human activities pressures, the ability trap/retain contaminants their vegetated sediments. However, there is still little information role of microplastic retention. Thus, study aims investigate capability an saltmarsh trap microplastics by comparing concentrations (saltmarsh) non-vegetated Microplastic content from sediment (vegetated non-vegetated) samples collected at sampling sites Lima River estuary was estimated using previously optimised extraction protocols, observed particles were then characterised accordingly size, colour, shape, polymer (by FTIR). Water also analysed for complement MPs characterisation within area. Microplastics detected all samples, with fibres being most common type found, followed fragments/particles. Overall, sediments, those species Juncus maritimus, presented a higher number items. These results indicated that tend trapped supporting fact significant influence on transport, distribution, accumulation areas.

Microplastics (MPs) are emerging contaminants of increasing concern as they may cause adverse effects and carry other contaminants, which potentially compromise human health. Despite occurring in aquatic ecosystems worldwide, the knowledge about MP presence different aquaculture systems their potential impact on seafood products is still limited. This study aimed to determine levels MPs water, feed, European seabass (Dicentrarchus labrax) from three relevant estimate exposure metals through consumption.

While there numerous studies on transport of microplastics, is a limited summary influencing factors, particularly those related inherent characteristics microplastics. Therefore, we present comprehensive review entire journey from sources production transport, encompassing following aspects: (1) distribution microplastics atmosphere; (2) biotic abiotic atmosphere, along with factors during process.

Estuaries act as significant pathways for plastic waste entry into the oceans, with microplastics (MPs) being intricately influenced by river and coastal hydrodynamics. MPs become entrapped within estuaries during transport, particularly at river–sea interface, which impacted tidal fluctuations. However, few studies have examined role of impacts variations on microplastic abundance export flux interface across contrasting hydrological regimes (dry vs. wet seasons). In this study, we conducted observations to assess abundance, composition, in Suixi Estuary Zhanjiang Bay, China The results indicated an overall mean 91.1 ± 75.0 items/L, was linked variations, decreasing high tides increasing low tides. Transparent color, fibrous shape, a size range 100–330 μm were most prevalent characteristics water samples. diversity higher season compared dry season. addition, influx about 1.61 × 109 items/year from sea both seasons. Additionally, regimes, forces, human activities identified influence flux.

Whereas expanded is sensitive fragmentation, sedimentation particles primarily sedimentation. The are integrated into CFs using an existing exposure effect factor microplastics in aquatic environments.
