Abstract Insects damaging and penetrating plastic packaged materials has been reported since the 1950s. Radical innovation breakthroughs of biodegradation have initiated discovery plastics by Tenebrio molitor larvae in 2015 followed Galleria mellonella 2017. Here we review updated studies on insect-mediated plastics. Plastic insect larvae, mainly some species darkling beetles (Tenebrionidae) pyralid moths (Pyralidae) is currently a highly active potentially transformative area research. Over past eight years, publications increased explosively, including discoveries ability different to biodegrade plastics, performance, contribution host microbiomes, impacts polymer types their physic-chemical properties, responsible enzymes secreted gut microbes. To date, almost all major polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), terephthalate (PET), polyurethane (PUR), polystyrene (PS) can be biodegraded T. ten other representing Tenebrionidae Pyralidae families.

A critical review of the adsorption-desorption characteristics of antibiotics on microplastics and their combined toxic effects

Environmental Technology & Innovation, Journal Year: 2024, Volume and Issue: 35, P. 103729 - 103729

Published: June 26, 2024

The interaction between microplastics (MPs) and pollutants is crucial for assessing the environmental risk of MPs. It necessary to pay attention adsorption/desorption behavior antibiotics on MPs due their potential role in antibiotic resistance. When MPs-loaded are ingested by organisms, they enter gastrointestinal tract undergo desorption, leading corresponding toxic effects. Existing literature primarily focuses adsorption behavior, while there a lack systematic generalizations desorption or combined effects organisms. Therefore, this article provides review mechanisms, biological tract. Desorption suggests that characteristics (aging hydrophobicity) components fluid (digestive enzyme species pH) can also have effect desorption. Moreover, summarizes induced MPs-antibiotics, demonstrating either enhance reduce plants, microorganisms, aquatic animals. Since methodological uniformity relevance natural environment main shortcomings existing literature, future research should focus actual water given region studying at gene, protein, metabolic levels. This direction expected provide valuable references insights evaluating antibiotics.

Microplastics, microfibers and associated microbiota biofilm analysis in seawater, a case study from the Vesuvian Coast, southern Italy

Journal of Hazardous Materials, Journal Year: 2025, Volume and Issue: 488, P. 137468 - 137468

Published: Feb. 4, 2025

The growing concerns regarding pollution from microplastics (MPs) and microfibers (MFs) have driven the scientific community to develop new solutions for monitoring ecosystems. However, many of proposed technologies still include protocols treating environmental samples that may alter plastic materials, leading inaccurate results both in observation counting. For this reason, we are refining a protocol, based on optical microscopy without use pretreatments, applicable different matrices, which allows not only counting but also complete morphological characterization MPs MFs. Previously, protocol has successfully been tested marine sediments Vesuvian area Gulf Naples (Italy) with good results. In present study, MFs seawater collected same geographical provide comprehensive overview their distribution environments. enabled collection information colonies microorganisms microparticles. Next Generation Sequencing (NGS) metagenomic us characterize microbiota composition sampled MPs, so-called Plastisphere. analytical approach allowed several potentially pathogenic bacteria, represent potential threat environment human health. fact, they exploit ability form biofilms plastics proliferate

Insights into Plastic Degradation Processes in Marine Environment by X-ray Photoelectron Spectroscopy Study

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(10), P. 5060 - 5060

Published: May 7, 2024

The present study employs X-ray photoelectron spectroscopy (XPS) to analyze plastic samples subjected degradation processes with the aim gain insight on relevant chemical and disclose fragmentation mechanisms. Two model plastics, namely polystyrene (PS) polyethylene (PE), are selected analyzed before after artificial UV radiation-triggered weathering, under simulated environmental hydrodynamic conditions, in fresh marine water for different time intervals. object of is identify quantify groups possibly evidencing occurrence hydrolysis oxidation reactions, which basis environment, determining macroplastic fragmentation.

Published: Jan. 1, 2025

In this study, the degradation behavior of poly(lactic acid) nanocomposite films (PLA/Hec-g@PS) under extreme natural environments was investigated, and degraded PLA based were applied to adsorb Cu(II). During early midstages degradation, surface roughness crack propagation rate PLA/Hec-g@PS significantly lower than those films. This could be due fact that Hec-g@PS enhanced interaction forces between C-O-C + CH
