Unsustainable plastic production, use and mismanagement has resulted in increased global pollution subsequent degradation into micro(nano)plastics the environment threatening sustainability. Micro(nano)plastic is pervasive caused widespread ecological impacts globally, including greenhouse gas emissions, contributing to climate change. Although downstream strategies curb exist, they are ineffective face of current production waste generation which still outpacing existing regulations. Thus, international community recognized a more holistic approach required reduce micro(nano)plastic pollution. This critical review highlights studies showing that unsustainable increasing all environmental compartments, yet few have documented successful prevention or removal techniques. offers constructive criticism some help advance ambitious reduction targets for transition towards sustainable plastics future.

Assessment of Four Engineered PET Degrading Enzymes Considering Large-Scale Industrial Applications

ACS Catalysis, Год журнала: 2023, Номер 13(20), С. 13156 - 13166

In recent years, enzymatic recycling of the widely used polyester polyethylene terephthalate (PET) has become a complementary solution to current thermomechanical for colored, opaque, and mixed PET. A large set promising hydrolases that depolymerize PET have been found enhanced by worldwide initiatives using various methods protein engineering. Despite achievements made in these works, it remains difficult compare enzymes' performance their applicability large-scale reactions due lack homogeneity between experimental protocols used. Here, we pave way standardized hydrolysis protocol reaction conditions relevant larger scale apply parameters four recently reported (LCCICCG, FAST-PETase, HotPETase, PES-H1L92F/Q94Y). We show FAST-PETase HotPETase intrinsic limitations may not permit application on scales, mainly relatively low depolymerization rates. With 80% depolymerization, PES-H1L92F/Q94Y be suitable candidate industrial scales upon further rounds enzyme evolution. LCCICCG outperforms other enzymes, converting 98% into monomeric products terephthalic acid (TPA) ethylene glycol (EG) 24 h. addition, optimized toward economic viability, reducing required amount factor 3 temperature from 72 68 °C. anticipate our findings advance coherent assessment enzymes materialize feasibility at scales.

Microplastics in the urban atmosphere: Sources, occurrences, distribution, and potential health implications

Journal of Hazardous Materials Advances, Год журнала: 2023, Номер 12, С. 100346 - 100346

Опубликована: Июль 20, 2023

Urbanization itself is a major and furthermost imperative contributor to the release of microplastics into environments. As cities grow develop, more plastic products are consumed discarded, resulting in increased pollution levels. Although researches on airborne (AMPs) urban regions scare, recent findings have shown high concentration them air residential areas. Textiles main source indoor ambiance, while traffic-related particles, textiles agricultural marine appear be responsible for polluting cities' outdoor atmosphere. Local metrological situation, topography physical features particles control behavior, distribution fate microplastics. Inhalation primary exposure route may induce toxicity respiratory tract. Understanding these factors crucial developing effective strategies mitigate their impact human health environment. Current work reviews published literature settings aiming at characterizing parent's materials, potential sources both spaces, possible impacts along with some further suggestions.

Abstract Since their invention, plastics have driven a revolution in behavior all aspects of our lives, including agriculture. In-use and as waste material, degrade accumulate agricultural systems. Accumulation plastic pollution systems has negative impacts on human health productivity but little is known about concentrations microplastics soils. Here we used historical time series to examine changes microplastic soils over time. Microplastics were stained with Nile Red quantified using fluorescence microscopy. We demonstrate that increased at higher rates are amended either organic or inorganic fertiliser between 1966 2022, suggesting fertilisers an important contributor This study provides evidence receptors reservoirs pollution, legacy which growing

The triple exposure nexus of microplastic particles, plastic-associated chemicals, and environmental pollutants from a human health perspective

Environment International, Год журнала: 2024, Номер 188, С. 108736 - 108736

The presence of microplastics (MPs) is increasing at a dramatic rate globally, posing risks for exposure and subsequent potential adverse effects on human health. Apart from being physical objects, MP particles contain thousands plastic-associated chemicals (i.e., monomers, chemical additives, non-intentionally added substances) captured within the polymer matrix. These are often migrating MPs can be found in various environmental matrices food chains; health effects. In addition to attributes MPs, plastic surfaces effectively bind exogenous chemicals, including pollutants (e.g., heavy metals, persistent organic pollutants). Therefore, act as vectors pollution across air, drinking water, food, further amplifying posed by exposure. Critically, fragmentation plastics environment increases risk interactions with cells, available leach adsorb transfer pollutants. This review proposes so-called triple nexus approach comprehensively map existing knowledge interconnected particles, Based data, there large gap regard cumulative nexus. Each component known induce genotoxicity, inflammation, endocrine disruption, but about long-term inter-individual lacking. Furthermore, not readily excreted organisms after ingestion they have been accumulated blood, cardiac tissue, placenta, etc. Even though number studies MPs-associated impacts rapidly, this underscores that pressing necessity achieve an integrated assessment MPs' order address future gaps.
