“…This behavior could be due to possible masking of Ag signal due to the great quantity of PM adhered on the surface of fibers or leaching of NPs due to tendency to suffer transformations during the washing process or with contact with sweat ( Mohan et al, 2019 ). According to the physicochemical characteristics of NPs, and environmental conditions, they can interact with other pollutants generating synergic toxicological effects in microorganisms and animals ( Zhu et al, 2020 , Malakar et al, 2021 , Singh et al, 2021 ). Moreover, NPs can be adsorbed on cell walls or skin, inhaled, or consumed involuntarily by organisms thus generating possible toxicological effects ( Turan et al, 2019 ).…”

In the present contribution, two nationwide surveys of personal protective equipment (PPE) pollution were conducted in Peru and Argentina aiming to provide valuable information regarding the abundance and distribution of PPE in coastal sites. Additionally, PPE items were recovered from the environment and analyzed by Fourier transformed infrared (FTIR) spectroscopy, Scanning electron microscopy (SEM) with Energy dispersive X-ray (EDX), and X-ray diffraction (XRD), and compared to brand-new PPE in order to investigate the chemical and structural degradation of PPE in the environment. PPE density (PPE m −2 ) found in both countries were comparable to previous studies. FTIR analysis revealed multiple polymer types comprising common PPE, mainly polypropylene, polyamide, polyethylene terephthalate, and polyester. SEM micrographs showed clear weathering signs, such as cracks, cavities, and rough surfaces in face masks and gloves. EDX elemental mapping revealed the presence of elemental additives, such as Ca in gloves and face masks and AgNPs as an antimicrobial agent. Other metals found on the surface of PPE were Mo, P, Ti, and Zn. XRD patterns displayed a notorious decrease in the crystallinity of polypropylene face masks, which could alter its interaction with external contaminants and stability. The next steps in this line of research were discussed.

“…The prospects of engineered nanoparticles (ENPs) of different sizes, shapes, and material properties in a number of applications have progressed rapidly (Guinée et al, 2017;Martínez et al, 2020), although the market benefits brought about by ENPs have also created some concerns of their possible effects on human health and environmental safety (Savolainen et al, 2013;Baun et al, 2017;Deng et al, 2017). Many studies emphasized the challenging relationship between typical ENPs features such as shape, size, modifications and the abiotic factors of the environment such as pH, divalent cation ions, dissolved organic carbon (Lu et al, 2017;Liu et al, 2018;Yu et al, 2018;Singh et al, 2021). Understanding how ENPs interact with the environment can assist in predicting the fate and effect of ENPs and may provide a basis for their ecological risk assessment.…”

“…4b). The different zeta potentials with the treatment of different biological media can be also originated by the treatment pH, and lower zeta potentials obtained at lower treatment pH because of the solvation effect on the particles (Singh et al 2021). The pH of the Gamble's and saliva uids were nearly neutral whereas ALF was 4.5.…”

Micro(nano)plastics are considered an emerging threat to human health since they have potential to interact with biological systems and already been found in the human body, e.g., lungs. However, limited data is available for their behavior under biological conditions and impact on human cells, specifically alveolar epithelial cells. In this study, micro(nano)plastics weathered to various simulated biological fluids (saliva, artificial lysosomal fluids, Gamble’s solution) during 2 h to 80 h. Pristine and weathered plastic particles were characterized by their surface chemistry, zeta potentials, and elemental composition. After, various toxicological endpoints (mitochondrial membrane potential, lactate dehydrogenase, protein, and antioxidant levels) were examined through A549 lung carcinoma cells. The surface characteristics of micro(nano)plastics and the toxicological endpoints of A549 were influenced by the simulated biological weathering, specifically at high concentration of micro(nano)plastics and increasing exposure under biological conditions. The results also indicated that toxicological endpoints had strong linked with the chemistry of plastics and included the multiple processes to the response of the plastics, for instance, the cell membrane integrity and mitochondrial activity were declined with the micro(nano)plastics under saliva weathering, contrarily, their protein and antioxidant activities increased. However, different biological pathways were obtained under artificial lysosomal fluid and Gamble’s solution.
