Over recent decades, marine microorganisms have increasingly adapted to plastic debris, forming distinct plastic-attached microbial communities. Despite this, the colonization and succession processes on surfaces in environments remain poorly understood. To address this knowledge gap, we conducted a microbiome experiment using four common polymers (PE, PP, PS, PET), as well glass wood, temperature-controlled seawater system over 2- 90-day period. We employed long-read 16S rRNA metabarcoding profile prokaryotic microbiome’s taxonomic composition at five time points throughout experiment. By applying Weighted Gene Co-expression Network Analysis (WGCNA) our data, identified unique signatures for 77 bacterial genera observed polymer-specific enrichment 39 genera. Our findings also revealed that most significant variations across occurred during initial stages, with potential intra-genus relationships are linked surface preferences. This research advances understanding of dynamics debris introduces robust statistical approach identifying specific taxa.

Plastic nurdles pose a significant environmental threat due to recurrent accidental spills into marine ecosystems. This report examines the nurdle pollution over 1498 km of Galician coastline (Spain) following spill 25 t Northwest Atlantic after loss six containers from Toconao vessel in December 2023. accident highlights urgent need for proactive, effective measures maritime transport prevent and mitigate such catastrophes. The complexity dispersion challenges evaluation their fate at sea, potential long-term consequences on ecosystem food web remain uncertain yet be investigated. also presents VIEIRA collaborative underscores critical role citizen-led initiatives responding disasters, advocates efficient policy reforms, involving cross-border collaboration. Furthermore, we call greater international cooperation underpin regulatory frameworks address growing hazard plastic worldwide.

Estuaries have been shown to be potential hotspots of microplastic accumulation, but the hydrodynamic conditions and particle properties that control this process need further investigation. We designed a series numerical particle-tracking experiments examine sensitivity retention in estuaries size, density varying tides freshwater flow. At end simulation, over 90 % sinking particles are retained estuary, rate is increased by high river runoff. In contrast, discharge increases number marginally-buoyant (i.e. close estuarine water) escape estuary. Larger size tends limit downstream transport can facilitate particles.

A set of laboratory experiments was conducted to assess the trapping efficiency buoyant plastic debris by estuarine vegetation Spartina maritima. Different hydrodynamic conditions typical salt marshes were simulated in a hydraulic flume. These included varying water levels between 40% and 90% stem height, wind speeds up 2 m/s, unidirectional current velocities 0.1 0.3 m/s. Moreover, three densities (small/medium/high) nine types shape (elongated/two-dimensional/three-dimensional) size (macro/meso) tested. The results indicate that maritima functions as natural trap. Specifically, study highlights lower surface velocities, higher densities, greater emergent heights, larger sizes significantly enhance efficiency. It also inferred for density comparable observed marshes, dominance velocity or effects on is primarily dependent shape. Consequently, has impact two-dimensional elements, whereas more significant three-dimensional elements. Finally, preliminary model developed integrate all aforementioned variables. This potential accuracy numerical predictions regarding transport fate using Lagrangian modeling, can be further refined incorporating additional data.

Investigating the impacts of plastics on our environment, and potential adverse effects fauna, has become increasingly important. While a number studies have shown that microplastic levels in sediments generally increase with proximity to urban regions, fewer investigated how vertebrate ingestion rates vary proximity. Here we explore influences plastic abundance by an intertidal fish (Forsterygion capito). Three sites around Dunedin City, New Zealand, were sampled. We demonstrate collected from areas located 2.5 10 km city centre ingested significantly more than at furthest site, 25 away city. Likewise, found least site tended contain microplastics. Despite this, little evidence suggest sediment microplastics can predict ingestion. Overall, this research provides further support deposition marine fauna.

The influence of algae presence in surface water on the settling velocities microplastics is unknown, and determining it challenging due to turbidity algal suspensions. Measuring velocity has traditionally relied either manual measurement techniques or 2D Particle Tracking Velocimetry (PTV). This study introduces a 3D-PTV method tailored determine effects (Synechoccocus sp.) microplastic speeds semi-large columns. We demonstrated that 3D PTV produces much more accurate results than particle tracking. Testing six experiments with varying concentrations revealed consistent across alignment some theoretical approximations. were concurrent calculated speeds. No density was found, which highly relevant for fate modeling eutrophic systems. highlight applicability accuracy tracking velocimetry further understanding behavior.
