Microplastics Derived from Food Packaging Waste—Their Origin and Health Risks

Materials, Journal Year: 2023, Volume and Issue: 16(2), P. 674 - 674

Published: Jan. 10, 2023

Plastics are commonly used for packaging in the food industry. The most popular thermoplastic materials that have found such applications polyethylene (PE), polypropylene (PP), poly(ethylene terephthalate) (PET), and polystyrene (PS). Unfortunately, plastic is disposable. As a consequence, significant amounts of waste generated, entering environment, undergoing degradation processes. They can occur under influence mechanical forces, temperature, light, chemical, biological factors. These factors present synergistic or antagonistic effects. result their action, microplastics formed, which undergo further fragmentation decomposition into small-molecule compounds. During process, various additives at plastics' processing stage also be released. Both negatively affect human animal health. Determination negative consequences on environment health not possible without knowing course processes products. In this article, we sources microplastics, causes places formation, transport particles, plastics often production storage, affecting said its

Recent Advances in MXenes Based Composites as Photocatalysts: Synthesis, Properties and Photocatalytic Removal of Organic Contaminants from Wastewater

ChemCatChem, Journal Year: 2023, Volume and Issue: 15(18)

Published: July 6, 2023

Abstract MXene has indeed gained significant attention in recent years as a promising photocatalyst for various applications, including photocatalytic degradation of pollutants. possesses several unique physical and chemical properties that make it suitable such its uniform planar structure, strong metal conductivity, effective functional groups, numerous derivatives. These contribute to the excellent photodegradation performance long‐term stability exhibited by MXene‐based photocatalysts compared other photocatalysts. composites, which are formed incorporating with materials, demonstrate even better activity due their abundant active sites porous structure. One crucial factor influencing is presence groups on surface MXene. play role process overall efficiency catalyst. To provide broader understanding photocatalysts, physicochemical briefly described this review. This includes structural characteristics, electrical groups. review also investigates synthesis routes preparing MXene, both natural state composites materials. methods essential tailoring meet specific requirements. Finally, discusses future work challenges photocatalysis. field holds great promise addressing environmental concerns improving organic compounds. However, further research needed optimize methods, enhance efficiency, explore practical applications

Quantification and characterization of microplastics in coastal environments: Insights from laser direct infrared imaging

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 912, P. 168835 - 168835

Published: Nov. 27, 2023

The study identified and quantified nine plastic polymers frequently detected in the environment by collecting sediment seawater samples from coastal areas Auckland, New Zealand. Polymer types, size distributions, number of microplastics (MPs) were analyzed using a laser direct infrared (LDIR) imaging technique. Compared to conventional spectroscopic or microscopic methods, LDIR enabled capturing quantifying MPs much lower ranges (20–5000 μm). results demonstrated widespread occurrence Auckland environment, with polyethylene terephthalate (PET) being most polymer. MP contamination levels ranged 13 83 particles per liter water 1200 3400 particles/kg dry sand beach sediments. Six additional locations investigated assess contribution stormwater drains environment. total count extracted sediments near reached maximum 18,000 sand, representing an order magnitude increase compared found at same location. In contrast prevalence PET polyamide observed waters, polyurethane emerged as predominant vicinity drain sediments, implying that variation could potentially stem distinct sources plastics. This significant disparity quality quantity underscored potential link between urban runoff pollution marine ecosystems.

Potential strategies for bioremediation of microplastic contaminated soil

Environmental Chemistry and Ecotoxicology, Journal Year: 2024, Volume and Issue: 6, P. 117 - 131

Published: Jan. 1, 2024

The escalating production and ubiquitous presence of plastics their degradation products, such as microplastics nanoplastics, pose a significant environmental threat. Microplastics enter the soil through various pathways, including agricultural practices, plastic degradation, wastewater disposal. Herein, we discussed harmful effects on physicochemical properties soil, plant growth, terrestrial fauna, microbial activity, potentially affecting stability nutrient cycle ecosystem. This review delves into recent advances in potential microplastic bioremediation approaches, phytoremediation strategies utilized by plants associated microbes to accumulate, immobilize, even degrade microplastics. Rhizosphere microorganisms play crucial role microplastics, utilizing them carbon source. Soil animals like earthworms, snails, mealworms can also contribute significantly ingesting degrading gut microbiota. Various microorganisms, bacteria fungi, different with help enzymes laccase, esterase, peroxidase, oxidoreductase, hydrolases depolymerise larger polymer chains smaller units that ultimately mineralize CO2, H2O, CH4. Genetic engineering synthetic biology are used create strains enhanced mineralization capabilities. It holds promise for efficient but requires further research real-world application scalable implementation. Overall, this comprehensively highlights approaches future recommendations tackling pollution. Further development enhancing biodegradation efficiency scaling up strategy protection.
