Comprehensive Understanding on the Aging Process and Mechanism of Microplastics in the Sediment–Water Interface: Untangling the Role of Photoaging and Biodegradation

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(36), P. 16164 - 16174

Published: Aug. 27, 2024

Microplastics (MPs) in coastal wetlands have been of great concern, but information on the aging behavior MPs sediment-water interface is still lacking. In this study, contribution a typical abiotic (photoaging) and biotic (biodegradation) process underlying pathway with different degradabilities (including polypropylene, polyethylene terephthalate, polylactic acid) were studied. With quantified relative importance photoaging (>55%) vs biodegradation, crucial MP was highlighted. This likely attributed to more generation reactive oxygen species (ROS) under sunlight irradiation conditions, containing O

Biofouling Promotes Higher Concentration of Heavy Metal on Disposable Face Masks than Microplastic Films and Particles in Seawater: Mechanisms and Potential Ecological Risks

ACS ES&T Water, Journal Year: 2024, Volume and Issue: 4(2), P. 377 - 387

Published: Jan. 8, 2024

The insufficient control of waste associated with personal protective equipment (PPE) resulted in a large influx disposable face masks (DFMs) marine environments. Herein, we investigated the biofilm colonization on three types polypropylene microplastics (MPs, i.e., DFMs, films, and particles) as well potential risks MP-associated heavy metals (HMs) seawater. Compared to conventional MP particles DFMs were conducive by microorganisms minerals, resulting formation typical spatial network structure. This triggered more HM adsorption biofilm-developed through surface complexation organic components biofilm. By BCR sequential extraction analysis, found that mineral comprised 70.2–85.6% 14.4–29.8% concentration respectively. In an vitro gastrointestinal tract model, had much higher desorption capacity for HMs than films. Moreover, ecological risk index was significantly films particles. Considering advocate reasonable recycling environmentally friendly treatment PPE pollutants should be considered bursting challenge sustainable coastal development.

An investigation into the effect of UV irradiation and biofilm colonization on adsorption and desorption behavior of polyurethane (PU) microplastics for bisphenol A (BPA)

Environmental Technology & Innovation, Journal Year: 2024, Volume and Issue: 35, P. 103662 - 103662

Published: May 8, 2024

Recent studies have demonstrated that microplastics (MPs) can act as a transport vector for pollutants in the environment. However, most focused on carbon-carbon backbone polymers, with little known about heteroatom polymers. In this study, polyurethane (PU) MPs were modified by UV irradiation and microorganism colonization to assess different aging treatments interaction behaviour (adsorption/desorption) between PU bisphenol A (BPA). The results of adsorption kinetics experiment illustrated process BPA could be described well pseudo-second order kinetic equation both fresh aged MPs. Although revealed highest saturated capacity, at low exposure concentrations (≤ 100 μg/L) capacities biofilm colonized very similar or even slightly higher than MPs, main mechanisms including H-bonding interactions π–π interactions. Fourier-transform infrared spectroscopy (FTIR) scanning electron microscopy (SEM) investigations suggested obvious physicochemical property changes (e.g., generation new functional groups, erosion, etc.) after colonization. This study also showed environments (ultrapure water, artificial seawater, simulated gastric fluid) affect adsorption/desorption via hydrophobic electrostatic surfaces. These further clarify undergone treatments, provides theoretical basis assessment environmental risks when coexist.
