A Review of Biodegradable Plastics: Chemistry, Applications, Properties, and Future Research Needs

Chemical Reviews, Journal Year: 2023, Volume and Issue: 123(16), P. 9915 - 9939

Published: July 20, 2023

Environmental concerns over waste plastics' effect on the environment are leading to creation of biodegradable plastics. Biodegradable plastics may serve as a promising approach manage issue environmental accumulation plastic in ocean and soil. type polymers that can be degraded by microorganisms into small molecules (e.g., H2O, CO2, CH4). However, there misconceptions surrounding For example, term "biodegradable" product labeling misconstrued public imply will degrade under any conditions. Such misleading information leads consumer encouragement excessive consumption certain goods increased littering products labeled "biodegradable". This review not only provides comprehensive overview state-of-the-art but also clarifies definitions various terms associated with plastics, including oxo-degradable enzyme-mediated biodegradation agents. Analytical techniques standard test methods evaluate biodegradability polymeric materials alignment international standards summarized. The summarizes properties industrial applications previously developed then discusses how biomass-derived monomers create new types utilizing their unique chemical from oxygen-containing functional groups. terminology methodologies covered paper provide perspective directions for design possess advanced performance practical benefits.

The potential for a plastic recycling facility to release microplastic pollution and possible filtration remediation effectiveness

Journal of Hazardous Materials Advances, Journal Year: 2023, Volume and Issue: 10, P. 100309 - 100309

Published: May 1, 2023

With current plastic production and the growing problem of global pollution, an increase improvement in recycling is needed. There limited knowledge or assessment microplastic pollution from point sources such as facilities globally. This pilot study investigates a mixed plastics facility UK to advance quantitative understanding (MP) release receiving waters. Raw wash water were estimate contain counts between 5.97 106 – 1.12 × 108 MP m−3 (following fluorescence microscopy analysis). The mitigation (filtration installed) was found remove majority microplastics >5µm, with high removal efficiencies for >40µm. Microplastics <5µm generally not removed by filtration subsequently discharged, 59-1184 tonnes potentially discharged annually. It recommended that additional smaller prior discharge incorporated management. Evidence suggest it may be important integrate into quality regulations. Further studies should conducted processes.

A review on microplastics in major European rivers

Wiley Interdisciplinary Reviews Water, Journal Year: 2024, Volume and Issue: 11(3)

Published: Jan. 6, 2024

Abstract The topic of riverine microplastics is great interest to the general public, yet univocal scientific knowledge on this limited. This review investigated occurrence in 6 major European rivers and their tributaries based results from 29 studies. We examined reviewed studies regard data quality reproducibility assessed abundance different sections water column. Furthermore, we chemical composition potential origin reported microplastics. found that polystyrene, polypropylene, polyethylene were most abundant polymer types. majority primary arose industry sector as well personal care cleaning products, whereas secondary constituted fibers synthetic textiles fragments diverse origins. highlighted diversity experimental analytical approaches could lead high uncertainties measurements abundance. presence was vary spatially likely due point nonpoint pollution sources anthropogenic activities. Heterogenous environmental processes impacted fate characterized by various forms, sizes, densities, ways. impeded identification representative quantitative across time frames. advocate for development standardized protocols research community ensure higher sampling, processing, analysis aquatic environments. recommend long‐term site‐specific monitoring with comparability better inform policy making. article categorized under: Science Water > Quality Life Conservation, Management, Awareness

A review of the neurobehavioural, physiological, and reproductive toxicity of microplastics in fishes

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 282, P. 116712 - 116712

Published: July 15, 2024

Microplastics (MPs) have emerged as widespread environmental pollutants, causing significant threats to aquatic ecosystems and organisms.This review examines the toxic effects of MPs on fishes, with a focus neurobehavioural, physiological, reproductive impacts, well underlying mechanisms toxicity.Evidence indicates that induce range neurobehavioural abnormalities in affecting social interactions cognitive functions.Altered neurotransmitter levels are identified key mechanism driving behavioural alterations following MP exposure.Physiological fishes exposed also reported, including neurotoxicity, immunotoxicity, oxidative stress.These physiological disruptions can compromise individual health organisms.Furthermore, linked exposure discussed, particular emphasis endocrine signaling pathways.These impair success fish species, impacting population numbers.Here we explore critical role mediating after MPs, focusing primarily hypothalamic-pituitary-gonadal axis.Our highlights urgent need for interdisciplinary research efforts aimed at elucidating full extent toxicity its implications ecosystems.Lastly, identify knowledge gaps future research, investigations into transgenerational if any, quantifying synergetic/antagonistic other pollutants.This expanded regarding potential risks wildlife is expected aid policymakers developing mitigation strategies protect species.

Microplastics are often found in the greatest quantities terrestrial environments, addition to those along coasts and oceans. They may get into water bodies from a variety of different sources such as deposition atmosphere, runoff polluted land, effluent municipal treatment plants. The objective this study is conduct comprehensive evaluation existing scientific literature related microplastics wastewater. Specifically, focus on investigating possible impacts wastewater containing both aquatic biota. Additionally, attempts identify any gaps current research, with intention informing future research priorities field. A selection over 200 papers subject microplastic pollution, covering years 2000–2023, has been selected prominent database. These encompass wide range topics, including recent advancements wastewater, their origins, behaviour potential adverse various organisms animals, soil microbial communities, plants, finally humans. results showed that using for irrigation can lead presence ecosystems facilitate transmission contaminants by interacting pollutants. findings also indicate although there significant investigation marine microplastics, prevalence contamination freshwater environments comparatively limited requires greater attention better understanding fate, transport, consequences relation water, qualities, polymer composition, forms, types land use.
