“…After screening various peaks as reference peaks, we selected the peak formed by the symmetric stretching vibration of the methylene (-CH 2 -) group, which exhibited little variation under all the different system treatments mentioned in this study, as the reference peak for PVC MPs. The CI was calculated as shown in Equation (7).…”

“…This rampant growth, however, has come with a cost: the fragmentation of discarded plastics in the environment results in the release of microplastics, varying in size from the nanometer scale up to 5 mm [2]. Microplastics are widely distributed and of various types detected in diverse environments, encompassing soil [3], oceans [4], rivers [5], bottled water [6], sediments [7], urban wastewater [8], and even the air we breathe [9]. Microplastics, which can adsorb harmful substances [10][11][12] and are toxic to organisms [13], have been found in various biological bodies [14][15][16], including humans [17].…”

The aging behavior of microplastics (MPs) in the environment has garnered significant attention, yet the exact aging process undergone by microplastics during advanced oxidation still remains unclear. This study emphasized elucidating the oxidation and dechlorination mechanisms of polyvinyl chloride microplastics (PVC MPs) within the UV-activated sodium percarbonate system (UV/SPC). After 35 h of UV/SPC (0.05 M) treatment, it exhibited effective dechlorination with a Cl− release of 100.62 ± 13.17 mg/L. And this treatment resulted in the fragmentation and release of fragments from the PVC MPs, thereby contributing to their further aging and dechlorination. In addition, an increase in oxygen-containing functional groups was identified. Quenching experiments confirm that ·OH and ·CO3− are the primary active species present in the system. In summary, the aging of PVC MPs results in a process of fragmentation, releasing fragments that are more fragile and susceptible to mineralization compared to the original PVC MPs. The release of chloride ions originates from the mineralization of these fragments released from PVC MPs by ·OH and ·CO3−. This study has provided valuable insights into the aging mechanisms of MPs in practical wastewater treatment.

“…Ineffective waste management systems lead to masks as a new source of microplastic pollution and a new threat to the environment (Fadare et al 2020 ; Dharmaraj et al 2021 ). Disposal of disposable masks has been found to be improper in cities (Akarsu et al 2021 ), oceans (Ardusso et al 2021 ), rivers (Cordova et al 2021 ), beaches (Flores-Cortés and Armstrong-Altrin 2022 ), and soils (Patrício Silva et al 2021 ).…”

A generation of microplastics caused by improper disposal of disposable masks has become a non-negligible environmental concern. In order to investigate the degradation mechanisms of masks and the release of microplastics under different environmental conditions, the masks are placed in 4 common environments. After 30 days of weathering, the total amount and release kinetics of microplastics released from different layers of the mask were studied. The chemical and mechanical properties of the mask were also discussed. The results showed that the mask released 25141±3543 particles/mask into the soil, which is much more than the sea and river water. The release kinetics of microplastics fit the Elovich model better. All samples correspond to the release rate of microplastics from fast to slow. Experiments show that the middle layer of the mask is released more than the other layers, and the amount of release was highest in the soil. And the tensile capacity of the mask is negatively correlated with its ability to release microplastics in the following order, which are soil > seawater > river > air > new masks. In addition, during the weathering process, the C-C/C-H bond of the mask was broken.
