Constraining the atmospheric limb of the plastic cycle

Proceedings of the National Academy of Sciences, Год журнала: 2021, Номер 118(16)

Опубликована: Апрель 12, 2021

Significance Microplastic particles and fibers generated from the breakdown of mismanaged waste are now so prevalent that they cycle through earth in a manner akin to global biogeochemical cycles. In modeling atmospheric limb plastic cycle, we show most plastics derived legacy production has continued build up environment. Roads dominated sources microplastics western United States, followed by marine, agriculture, dust emissions downwind population centers. At current rate increase (∼4% per year), understanding consequences atmosphere should be priority.

Plastic pollution in the Arctic

Nature Reviews Earth & Environment, Год журнала: 2022, Номер 3(5), С. 323 - 337

Опубликована: Апрель 5, 2022

Plastic pollution is now pervasive in the Arctic, even areas with no apparent human activity, such as deep seafloor. In this Review, we describe sources and impacts of Arctic plastic pollution, including debris microplastics, which have infiltrated terrestrial aquatic systems, cryosphere atmosphere. Although some from local — fisheries, landfills, wastewater offshore industrial activity distant regions are a substantial source, carried lower latitudes to by ocean currents, atmospheric transport rivers. Once accumulates certain affects ecosystems. Population-level information sparse, but interactions entanglements ingestion marine been recorded for mammals, seabirds, fish invertebrates. Early evidence also suggests between climate change pollution. Even if emissions halted today, fragmentation legacy will lead an increasing microplastic burden ecosystems, already under pressure anthropogenic warming. Mitigation urgently needed at both regional international levels decrease production utilization, achieve circularity optimize solid waste management treatment. microplastics ubiquitous Arctic. This Review describes sources, distribution consequences calls immediate action mitigate further ecosystem impact.

Global concentrations of microplastics in soils – a review

SOIL, Год журнала: 2020, Номер 6(2), С. 649 - 662

Опубликована: Дек. 17, 2020

Abstract. Worldwide, microplastics (MPs) have been commonly recognized as a threat to soil ecosystems. Terrestrial soils are widely contaminated by MPs due the application of sewage sludge and wastewater, plastic mulching, littering, input tire wear from roads atmospheric deposition. Within last decade, an increasing number individual studies focused on item counts masses in different global environments. We reviewed these achieve representative picture common degrees contamination. The majority prospected agricultural horticultural sites were exposed mulching film showed concentrations <13 000 items kg−1 dry 4.5 mg soil. Microplastic vicinity municipal areas thereby 10 times larger compared rural sites. measurement was generally underrepresented numbers, mass data often generated microscopic analyses using shape-to-mass models instead direct measurements. Extreme values, such industrial sites, exceed 2 4 orders magnitude, which might be attributed not only land use but also applied methods measurement. Campaigns that focus other entry pathways like composts, road dust runoff littering or uses grassland, forest, fallow wilderness well landfills nonexistent. Background loads, deposition, excluded measurements and, thus, overestimate contribution analyzed pathway total load. Other light density MP, e.g., films, therefore underestimated amount MP. Despite limitations, give impression spectrum MP good basis for experiments examining effects soils. Based collected data, we identified problems past recommend future experimentation take into account standardized extraction quantification, proper characterization sampling their history exploration yet uses.

The fundamental links between climate change and marine plastic pollution

The Science of The Total Environment, Год журнала: 2021, Номер 806, С. 150392 - 150392

Plastic pollution and climate change have commonly been treated as two separate issues sometimes are even seen competing. Here we present an alternative view that these fundamentally linked. Primarily, explore how plastic contributes to greenhouse gas (GHG) emissions from the beginning end of its life cycle. Secondly, show more extreme weather floods associated with change, will exacerbate spread in natural environment. Finally, both occur throughout marine environment, ecosystems species can be particularly vulnerable both, such coral reefs face disease through climate-driven increased global bleaching events. A Web Science search showed studies ocean often siloed, only 0.4% articles examining stressors simultaneously. We also identified a lack regional industry-specific cycle analysis data for comparisons relative GHG contributions by materials products. Overall, suggest rather than debate over importance or pollution, productive course would determine linking factors between identify solutions combat crises.

Microplastics in Honey, Beer, Milk and Refreshments in Ecuador as Emerging Contaminants

According to the latest research, marine products have greatest potential for microplastic (MPs) contamination. Therefore, their presence in terrestrial food has not managed attract much attention—despite fact that future they may represent a serious environmental risk. Research conducted Europe and US indicated of MPs tap water, bottled table salt, honey, beer snails human consumption. The yet been evaluated Latin America. This work focused on evaluating two widely consumed beverages: milk soft drinks. Furthermore, honey samples were analyzed compared findings literature. All sourced Ecuador. In order determine correlations with intensity anthropogenic activity, both industrially processed craft studied. For analysis, an improvement previous techniques used was applied. technique uses microfiltration followed by degradation organic matter hydrogen peroxide—and finally, continuous rinsing deionized water. Size ranges established between 0.8–200 mm. number microplastics found 10 100 MPs/L, average around 40 MPs/L. sizes particles study are range 13.45 6742.48 μm fibers, 2.48 247.54 fragments. From composition analysis carried out FTIR, we able confirm 12% microplastic. results generally showed greater those registered Europe, probably due processing methods rather than pollution. Regarding composition, main polyethylene, polypropylene polyacrylamide.
