Reaching New Heights in Plastic Pollution—Preliminary Findings of Microplastics on Mount Everest

One Earth, Год журнала: 2020, Номер 3(5), С. 621 - 630

Опубликована: Ноя. 1, 2020

Mount Everest was once a pristine environment. However, due to increased tourism, waste is accumulating on the mountain, with large proportion being made of plastic. This research aimed identify and characterize microplastic (MP) pollution near top highest mountain Earth could illustrate implications for environment people living below. Stream water snow were collected from multiple locations leading up to, including, Balcony (8,440 m.a.s.l). MPs detected at an ~30 MP L−1 in ~1 stream water, majority fibrous. Therefore, deposition Mt. expected rise. At pivotal point exploration remote areas, environmental stewardship should focus technological other advances toward minimizing sources pollution.

Plastics in the Earth system

Science, Год журнала: 2021, Номер 373(6550), С. 51 - 55

Опубликована: Июль 1, 2021

Plastic contamination of the environment is a global problem whose magnitude justifies consideration plastics as emergent geomaterials with chemistries not previously seen in Earth's history. At elemental level, are predominantly carbon. The comparison plastic stocks and fluxes to those carbon reveals that quantities present some ecosystems rival quantity natural organic suggests geochemists should now consider their analyses. Acknowledging adopting geochemical insights methods can expedite our understanding Earth system. Plastics also be used global-scale tracers advance system science.

Microplastic effects on carbon cycling processes in soils

PLoS Biology, Год журнала: 2021, Номер 19(3), С. e3001130 - e3001130

Опубликована: Март 30, 2021

Microplastics (MPs), plastic particles <5 mm, are found in environments, including terrestrial ecosystems, planetwide. Most research so far has focused on ecotoxicology, examining effects performance of soil biota controlled settings. As pivots to a more ecosystem and global change perspective, questions about soil-borne biogeochemical cycles become important. MPs can affect the carbon cycle numerous ways, for example, by being themselves influencing microbial processes, plant growth, or litter decomposition. Great uncertainty surrounds nano-sized particles, an expected by-product further fragmentation MPs. A major concerted effort is required understand pervasive functioning soils ecosystems; importantly, such needs capture immense diversity these terms chemistry, aging, size, shape.

Microplastics in the soil environment: A critical review

Environmental Technology & Innovation, Год журнала: 2022, Номер 27, С. 102408 - 102408

Опубликована: Фев. 12, 2022

Environmental pollution of microplastics (MPs) is known to be anthropogenically mediated menace biosphere and becoming a debatable concern globally. Large quantities plastic fragments are left behind after crop cultivation. The leftover debris, gradually degrade into minute with diameter less than 5 mm, as MPs. MPs responsible for many changes in the soil physicochemical characteristics, including porosity, enzymatic activities, microbial plant growth, yield. Because their ubiquitous nature, high specific surface area strong hydrophobicity, play an important role transportation toxic chemicals such plasticisers, polycyclic aromatic hydrocarbons (PAHs), antibiotics, potentially elements (PTEs). may transported deep can pollute underground water. This review paper investigates deleterious effects on environment, microbes, flora, fauna production, highlights general concept contamination well its possible environmental consequences. also converses some key areas future research stakeholders concerned policymaking

Microplastics Increase Soil pH and Decrease Microbial Activities as a Function of Microplastic Shape, Polymer Type, and Exposure Time

Frontiers in Environmental Science, Год журнала: 2021, Номер 9

Опубликована: Июнь 23, 2021

Microplastic pollution is a topic of increasing concern, especially since this issue was first addressed in soils. Results have so far been variable terms effects, suggesting that there substantial context-dependency microplastic effects soil. To better define conditions may affect microplastic-related impacts, we here examined as function shape and polymer type, tested if on soil properties microbial activities change with incubation time. In our laboratory study, evaluated twelve different secondary microplastics representing four shapes: fibers, films, foams fragments; eight types: polyamide (PA), polycarbonate (PC), polyethylene (PE), polyester (PES), terephthalate (PET), polypropylene (PP), polystyrene (PS), polyurethane (PU). We mixed the sandy (0.4% w/w) incubated at 25°C for 31 days. Then, collected samples 3rd, 11th, 31st day, measured pH, respiration enzyme (soil enzymatic activities). Our results showed could depending were altered Soil pH increased fragments overall decreased days then increased.
