Despite the relatively rich literature on omnipresence of microplastics in marine environments, current status and ecological impacts global Marine Protected Areas (MPAs) are still unknown. Their ubiquitous occurrence, increasing volume, ecotoxicological effects have made microplastic an emerging pollutant. Given critical conservation roles MPAs that aim to protect vulnerable species, biodiversity, resources, it is essential a comprehensive overview abundance, distribution, characteristics including their buffer zones. Here, extensive data were collected screened based 1565 peer-reviewed from 2017 2020, GIS-based approach was applied improve outcomes by considering boundary limits. Microplastics seawater samples verified within boundaries 52 MPAs; after zones, 1/3 more (68 MPAs) identified as contaminated microplastics. A large range levels summarized water volume (0-809,000 items/m3) or surface area (21.3-1,650,000,000 items/km2), which likely due discrepancy sampling analytical methods. Fragment most frequently observed shape fiber abundant shape. PE PP common also polymer types. Overall, 2/3 available reported higher than 12,429 items/km2, indicating alone cannot against pollution. The limitations future directions discussed toward post-2020 Global Biodiversity Framework goals.

Public summary•The plastisphere selectively assembles a microbiome distinct from that of natural habitats.•New microbial coexistence patterns are yielded in the plastisphere.•Altered functions threaten ecosystem functioning.•Enrichment pathogens poses critical challenge to "One Health".AbstractPlastic offers new niche for microorganisms, plastisphere. The ever-increasing emission plastic waste makes it understand ecology and associated effects. Here, we present global fingerprint plastisphere, analyzing samples collected freshwater, seawater, terrestrial ecosystems. community has clearly higher heterogeneity more deterministically dominated assembly compared habitats. New patterns—loose fragile networks with mostly specialist linkages among microorganisms rarely found habitats—are seen Plastisphere microbiomes generally have great potential metabolize organic compounds, which could accelerate carbon turnover. Microorganisms involved nitrogen cycle also altered especially freshwater plastispheres, where high abundance denitrifiers may increase release nitrite (aquatic toxicant) nitrous oxide (greenhouse gas). Enrichment animal, plant, human means become an increasingly mobile reservoir harmful microorganisms. Our findings highlight if trajectory emissions is not reversed, expanding pose planetary health challenges.Graphical abstract

The “Microplastome” – A Holistic Perspective to Capture the Real-World Ecology of Microplastics

Environmental Science & Technology, Год журнала: 2024, Номер unknown

Опубликована: Фев. 8, 2024

Microplastic pollution, an emerging pollution issue, has become a significant environmental concern globally due to its ubiquitous, persistent, complex, toxic, and ever-increasing nature. As multifaceted diverse suite of small plastic particles with different physicochemical properties associated matters such as absorbed chemicals microbes, future research on microplastics will need comprehensively consider their multidimensional attributes. Here, we introduce novel, conceptual framework the "microplastome", defined entirety various (<5 mm), found within sample overall toxicological impacts. novel concept, this paper aims emphasize call for collective quantification characterization more holistic understanding regarding differences, connections, effects in biotic abiotic ecosystem compartments. Deriving from lens, present our insights prospective trajectories characterization, risk assessment, source apportionment microplastics. We hope new paradigm can guide propel microplastic toward era contribute informed strategy combating important issue.

Microplastic (MPs) pollution has become a subject of environmental concern due to its wide ubiquity in the environment. Microplastics are possible sources other hazardous chemicals aquatic organisms their composition and sorption properties. In this study, MPs occurrence water sediment samples Plankenburg River, Western Cape, South Africa was investigated. The physicochemical characterization river done onsite. 30 L were collected filtered 10 triplicates through 250 μm mesh onsite using metal bucket. An additional 12 sample 4 20 laboratory. extraction from laboratory by density separation. Sediment also at selected sites, oven-dried microplastics Sampling conducted over four seasons - spring, summer, autumn, winter. classified visual observation Fourier Transform Infrared Spectroscopy (FTIR-ATR). seasonal distribution surface varied across all sites. However, spring had highest (5.13 ± 6.62 MP/L) least, autumn (1.52 2.54 MP/L). observed (1587.50 599.32 MP/kg). Fibres most dominant microplastic particle type (shape), with size range 500-1000 different infrared spectroscopic analysis confirmed polymer be polyethylene. This study provides an understanding River system gives baseline for future monitoring assessment African freshwater systems.
