Abstract There is strong evidence that the seafloor constitutes a final sink for plastics from land sources. also part of lying on shallow are washed up back to shoreline. However, little known natural trapping processes leading such landwards return. Here we investigate microplastics and larger plastic debris within beached seagrass remains including balls (aegagropilae) made aggregates vegetal fibers intertwined by seawater motion. We found 1470 items per kg plant material, which were mainly composed negatively buoyant polymer filaments fibers. Our findings show meadows promote aggregation with lignocellulosic fibers, then ejected escape coastal ocean. results how seagrasses, one key ecosystems Earth in terms provision goods services, counteract marine pollution. In view our findings, regression some regions acquires new dimension.

Although the study of microplastics in aquatic environment incorporates a diversity research fields, it is still its infancy many aspects while comparable topics have been studied other disciplines for decades. In particular, extensive sedimentology can provide valuable insights to guide future research. To advance our understanding comparability natural sediments with microplastics, we take an interdisciplinary look at existing literature describing particle properties, transport processes, sampling techniques and ecotoxicology. Based on analysis, define seven goals that are essential improve be tackled by learning from sediment research, identify relevant tasks achieve each goal. These address (1) description microplastic particles, (2) interaction environmental substances, (3) vertical distribution (4) erosion deposition behaviour (5) impact biota transport, (6) methods (7) toxicity. When should specifically draw knowledge sediments, example using shape factors or applying determining principal dimensions non-spherical particles.

Microplastics were recently found to aggregate in the blue carbon ecosystems (BCEs), which are known for their ability store by slowing down water flow. However, evidence is largely lacking on how accumulation of microplastics related sequestration BCEs and if this trap effect driven its biological characteristics. In study, was evaluated various seagrasses (Zostera japonica, Halophila ovalis, beccarii) mangroves (Aegiceras corniculatum Avicennia marina). Significant seagrass meadow dominated H. beccarii mangrove forest A. marina, with enriched 1.3 17.6 times compared corresponding unvegetated sites. The abundance varied greatly from 17.68 ± 8.10 611.75 81.52 particles per kg dry sediment, highest marina sediments. A strong positive correlation between particulate organic content at all study sites (Pearson, R = 0.86, p < 0.01). Higher diversity microplastic colors size meadow, higher shapes forest. Our results added new insights understanding mechanism trapping coupled behavior sediment.

How plastic debris and associated chemicals impact the marine food web: A review

Опубликована: Янв. 26, 2023

Contamination from plastic debris is omnipresent in marine environments, posing a substantial risk to organisms, food webs and the ecosystem. The overlap between size range of pollution with prey means that plastics are readily available for consumption by organisms at all trophic levels. Large can directly result death larger through entanglement, strangulation, choking starvation false sense satiation. Whereas smaller debris, such as micro- nano-plastics have adverse impact due their large surface area volume ratio ability translocate within an organism.

Southeast Asia is considered to have some of the highest levels marine plastic pollution in world. It therefore vitally important increase our understanding impacts and risks ecosystems essential services they provide support development mitigation measures region. An interdisciplinary, international network experts (Australia, Indonesia, Ireland, Malaysia, Philippines, Singapore, Thailand, United Kingdom, Vietnam) set a research agenda for region, synthesizing current knowledge highlighting areas further Asia. Using an inductive method, 21 questions emerged under five non-predefined key themes, grouping them according which: (1) characterise Asia; (2) explore its movement fate across region; (3) describe biological chemical modifications undergoes; (4) detail environmental, social, economic impacts; and, finally, (5) target regional policies possible solutions. Questions relating these priority highlight importance better pollution, degradation, it can generate communities different ecosystem services. Knowledge aspects will help actions which currently suffer from transboundary problems, lack responsibility, inaction tackle issue point source Being profoundly affected by Asian countries opportunity test effectiveness innovative socially inclusive changes governance, as well both high low-tech solutions, offer insights actionable models rest
