Plastic pollution is ubiquitous in terrestrial and aquatic ecosystems. waste exposed to the environment creates problems of significant concern for all life forms. production accumulation natural are occurring at an unprecedented rate due indiscriminate use, inadequate recycling, deposits landfills. In 2019, global plastic was 370 million tons, with only 9% it being recycled, 12% incinerated, remaining left or The leakage wastes into ecosystems rate. management a challenging problem researchers, policymakers, citizens, other stakeholders. Therefore, here, we summarize current understanding concerns plastics (microplastics nanoplastics) on overall goal this review provide background assessment adverse effects ecosystems; interlink sustainable development goals; address policy initiatives under transdisciplinary approaches through cycle assessment, circular economy, sustainability; identify knowledge gaps; recommendations. community involvement socio-economic inputs different countries presented discussed. ban policies public awareness likely major mitigation interventions. need circularity assess potential environmental impacts resources used throughout product’s span emphasized. Innovations needed reduce, reuse, recycle, recover find eco-friendly replacements plastics.

Plastics in the Earth system

Science, Journal Year: 2021, Volume and Issue: 373(6550), P. 51 - 55

Published: July 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.

A review of the removal of microplastics in global wastewater treatment plants: Characteristics and mechanisms

Environment International, Journal Year: 2020, Volume and Issue: 146, P. 106277 - 106277

Published: Nov. 20, 2020

Wastewater treatment plants (WWTPs) are considered to be the main sources of microplastic contaminants in aquatic environment, and an in-depth understanding behavior microplastics among critical technologies WWTPs is urgently needed. In this paper, characteristics removal 38 11 countries worldwide were reviewed. The abundance influent, effluent, sludge was compared. Then, based on existing data, efficiency compared by quantitative analysis. Particularly, detailed mechanisms including primary settling with flocculation, bioreactor system, advanced oxidation membrane filtration discussed. Thereafter, load ecological hazard discharged from into soil environments summarized. influent ranged 0.28 particles L-1 3.14 × 104 L-1, while that effluent 0.01 2.97 102 L-1. within range 4.40 103-2.40 105 kg-1. addition, there still 5.00 105-1.39 1010 environment each day Moreover, technologies, analysis revealed filter-based exhibited best efficiency. Fibers large particle sizes (0.5-5 mm) easily separated settling. Polyethene small-particle size (<0.5 trapped bacteria activated system. negative impact wastewater plant worthy attention. unknown transformation products their corresponding toxicity need research.

Marine microplastics as vectors of major ocean pollutants and its hazards to the marine ecosystem and humans

Progress in Earth and Planetary Science, Journal Year: 2021, Volume and Issue: 8(1)

Published: Jan. 22, 2021

Abstract Microplastic pollutes water, land, air, and groundwater environments not only visually but also ecologically for plants, animals, humans. has been reported to act as vectors by sorbing pollutants contributing the bioaccumulation of pollutants, particularly in marine ecosystems, organisms, subsequently food webs. The inevitable exposure microplastic humans emphasises need review potential effects, pathways, toxicity toward human health. Therefore, this was aimed reveal risks pollutant sorption humans, well dominant types sorbed microplastic, that are bioaccumulated living organisms ecosystem. possible factors influencing ecosystems were reviewed. revealed prevailing abundance geographical distribution aquatic environment globally. literature characteristics, chemical interactions, water properties played a role microplastic. evidence posing direct medical threat is still lacking albeit substantial health hazards microplastic-associated monomers, additives, pollutants. This recommends future research on existing knowledge gaps research, which include
