“…MNPs have been detected in various environmental compartments, including oceans (Eriksen et al, 2014), rivers (Blettler et al, 2017), lakes (Eriksen et al, 2013), soil (Liu et al, 2018), and air (Kirchsteiger et al, 2023), signifying their ubiquitous presence and potential impact on diverse ecosystems. These tiny plastic particles enter the oceans through various pathways, such as direct release from coastal and marine activities, runoff from land, and the breakdown of larger plastic debris (Alprol et al, 2021).…”

In recent decades, the ubiquity of micro and nanoplastics (MNPs) pollution has emerged as a global concern due to its potential risks to both ecological and human health. The detrimental effects of MNPs have resulted in significant changes in the physicochemical and biological properties of terrestrial soil and benthic sediment. These alterations have led to a disrupted nutrient cycle, potential future climate hazards, and further impacts on ecosystem services. This review aims to discuss the possible origins, composition, abundance, life cycle, and transport processes of MNPs in aquatic and terrestrial ecosystems. It seeks to understand the potential ecological and human health risks associated with MNPs pollution and explores their implications for biodiversity conservation and ecosystem services. Moreover, this review highlights the advanced analytical techniques used to detect and quantify MNPs. It further suggests policy frameworks to combat this pollution in natural environments. The findings of this review are intended to assist environmentalists, microbiologists, hydrologists, and policymakers in identifying scientific gaps and pragmatic solutions to reduce MNPs pollution. Future research should investigate the intake mechanism and impact of MNPs on plants in different ecosystems, as well as their effects on food chains and human health. This will ensure that the ecological and human health risks associated with MNPs pollution can be timely mitigated.

“…PAHs have been identied as a class of compound that can sorb to microplastic particles. 64 These are summarized in Table S1. † All of these compounds have been previously identied in prior studies, 34,37,38,55,65,66 but this is the rst time they have been systematically identied in both the S-and VE-based systems for the resin, composite, and waste.…”

“…In the intratracheal instillation, it was indicated that the potential for lung disorders by polypropylene may not be low. The amount of atmosphere microplastics in the real environment is reported to be 238 ng/m 3 at PM2.5 size [29]. The number concentration is affected by the measurement location, conditions, and analysis method, but it has been reported to range from a few to several thousand particles/m 3 [2,3,30].…”

Background Microplastics have been detected in the atmosphere as well as in the ocean, and there is concern about their biological effects in the lungs. We conducted a short-term inhalation exposure and intratracheal instillation using rats to evaluate lung disorders related to microplastics. We conducted an inhalation exposure of polypropylene fine powder at a low concentration of 2 mg/m3 and a high concentration of 10 mg/m3 on 8-week-old male Fischer 344 rats for 6 hours a day, 5 days a week for 4 weeks. We also conducted an intratracheal instillation of polypropylene at a low dose of 0.2 mg/rat and a high dose of 1.0 mg/rat on 12-week-old male Fischer 344 rats. Rats were dissected from 3 days to 6 months after both exposures, and bronchoalveolar lavage fluid (BALF) and lung tissue were collected to analyze lung inflammation and lung injury. Results Both exposures to polypropylene induced a persistent influx of inflammatory cells and expression of CINC-1, CINC-2, and MPO in BALF from 1 month after exposure. Genetic analysis showed a significant increase in inflammation-related factors for up to 6 months. The low concentration in the inhalation exposure of polypropylene also induced mild lung inflammation. Conclusion These findings suggest that inhaled polypropylene, which is a microplastic, induces persistent lung inflammation and has the potential for lung disorder. Exposure to 2 mg/m3 induced inflammatory changes and was thought to be the Lowest Observed Adverse Effect Level (LOAEL) for acute effects of polypropylene.
