Microplastics are of increasing interest as one the most important threats to natural environment and aquatic life. One main pathways microplastics entering terrestrial wastewater treatment plants. The aim this study was investigate occurrence removal MPs in both sludge from an MBR-based a WWTP. focus is on amount emitted into environment, efficiency plants how their operation design, could be improved reduce presence these pollutants effluent. results showed that influent (SI) had mean concentration 507 ± 70 L-1, reactor tank (SRS) increases 1.77 × 107 1.61 kg-1 (dw) permeate (SP) estimated decreased 1.58 1.08 L-1. This 99.69%, with respect average MPs. After clarifier (SC) sand filtration (SSF) 17.38 4.71 L-1 2.93 1.50 respectively were found, resulting 96.58% 99.42%, respectively, regarding inlet water plant. two predominant forms all samples (except for SCS) fragments fibers. In total 25 types polymers detected, only 5 resulted samples, detected polymer families Acrylates Polyethylenes.

Environmental pollution indices: a review on concentration of heavy metals in air, water, and soil near industrialization and urbanisation

Discover Environment, Год журнала: 2024, Номер 2(1)

Опубликована: Янв. 25, 2024

Abstract Current industrial operations pollute the world’s land, water, and air with heavy metals. Metals’ environmental behaviour geographical distribution near production. Heavy metal contamination potential was assessed using geoaccumulation index, enrichment factor, other criteria. concentrations have increased due to waste, geochemical shifts, agriculture, mining. Modifying cell structure, metals can harm cause cancer. We need develop conduct comprehensive monitoring determine if production mining is causing elevated levels nearby area in zone. This review shares contemporary on its nature, origin, extent.

Advances in microbial exoenzymes bioengineering for improvement of bioplastics degradation

Chemosphere, Год журнала: 2024, Номер 355, С. 141749 - 141749

Опубликована: Март 21, 2024

Plastic pollution has become a major global concern, posing numerous challenges for the environment and wildlife. Most conventional ways of plastics degradation are inefficient cause great damage to ecosystems. The development biodegradable offers promising solution waste management. These designed break down under various conditions, opening up new possibilities mitigate negative impact traditional plastics. Microbes, including bacteria fungi, play crucial role in bioplastics by producing secreting extracellular enzymes, such as cutinase, lipases, proteases. However, these microbial enzymes sensitive extreme environmental temperature acidity, affecting their functions stability. To address challenges, scientists have employed protein engineering immobilization techniques enhance enzyme stability predict structures. Strategies improving substrate interaction, increasing thermostability, reinforcing bonding between active site substrate, refining activity being utilized boost functionality. Recently, bioengineering through gene cloning expression potential microorganisms, revolutionized biodegradation bioplastics. This review aimed discuss most recent strategies modifying bioplastic-degrading terms functionality, thermostability enhancement, binding site, with other improvement surface action. Additionally, discovered exoenzymes metagenomics were emphasized.

Tandem microplastic degradation and hydrogen production by hierarchical carbon nitride-supported single-atom iron catalysts

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Окт. 10, 2024

Abstract Microplastic pollution, an emerging environmental issue, poses significant threats to aquatic ecosystems and human health. In tackling microplastic pollution advancing green hydrogen production, this study reveals a tandem catalytic degradation-hydrogen evolution reaction (MPD-HER) process using hierarchical porous carbon nitride-supported single-atom iron catalysts (FeSA-hCN). Through hydrothermal-assisted Fenton-like reactions, we accomplish near-total ultrahigh-molecular-weight-polyethylene degradation into C 3 -C 20 organics with 64% selectivity of carboxylic acid under neutral pH, leap beyond current capabilities in efficiency, selectivity, eco-friendliness, stability over six cycles. The system demonstrates versatility by degrading various daily-use plastics across different settings. mixture FeSA-hCN plastic products further achieves 42 μmol h ‒1 illumination, outperforming most existing photoreforming methods. This MPD-HER not only provides scalable economically feasible strategy combat but also contributes the economy, far-reaching implications for global sustainability initiatives.
