“…Although we assume that nanoplastics at the Siberian site originate from terrestrial sources, we cannot rule out an oceanic source. Marine waters are capable of ejecting plastics through a process of bubble burst and wave action, with the ejected plastics then being available for wind transport [59,60]. Our site is just 150 km from the coast and the dispersion models show that particles do arrive at the site from above the ocean (figure 5), and so we acknowledge that this is also a viable route for plastics to enter these waterbodies.…”

It is now established that microplastics are a pervasive presence in aquatic and terrestrial ecosystems. The same is assumed to be true for nanoplastics but data are lacking due to technical difficulties associated with sample analysis. Here, we measured nanoplastics in waterbodies at two contrasting sites: remote Siberian Arctic tundra and a forest landscape in southern Sweden. Nanoplastics were detected in all sampled Swedish lakes (n = 7) and streams (n = 4) (mean concentration = 563 µg l-1) and four polymer types were identified (polyethylene, polyvinyl chloride, polypropylene, polyethylene terephthalate). In Siberia nanoplastics were detected in 7/12 sampled lakes, ponds and surface flooding, but only two polymer types were detected (polyvinyl chloride and polystyrene) and concentrations were lower (mean 51 µg l-1). Based on back-calculation of air mass trajectories and particle dispersion, we infer that nanoplastics arrive at both sites by aerial deposition from local and regional sources. Our results suggest that nanoplastics may be a near-ubiquitous presence even in remote ecosystems.

“…34,35 On a planetary scale, modeling the compositions of sea spray aerosol is essential since it dictates the radiant properties of the atmosphere, in addition to impacting atmospheric pollution, global climate, and ecological and material cycles, 2,27, [73][74][75] with nanoplastics and microplastics found in sea spray aerosols being of major concern in recent years. 20,21 By advancing the quantification of the particulate concentration in bubble bursting aerosols, our study may be incorporated into a global model for more accurate prediction of sea spray aerosol compositions.…”

“…[1][2][3][4] In natural water bodies, bubbles are typically smaller than a millimeter in diameter, [5][6][7][8] and mainly produce jet drops with a typical size of several to dozens of microns instead of film drops. [9][10][11][12][13] These small drops may remain suspended in the air, containing various compositions from the bulk water, 14 such as sea salts, 3,15 surfactants, 16,17 oil spills, 18,19 nanoplastic and microplastic particles, 20,21 and even nano/micro-sized organisms. [22][23][24] Therefore, bubble bursting jets play an important role in mediating mass transfer across the air-water interface in a wide range of industrial, geological, and biological phenomena, including the flavor release from sparkling beverages 25 , sea spray aerosol generation, 3,13,26 oceanic vegetative reproduction, 27 and airborne pathogen transmission.…”

Bubbles dispersed in liquids are widely present in many natural and industrial processes, and play a key role in mediating mass transfer during their lifetime from formation to rising to bursting. In particular, nano/micro-sized particulates and organisms, present in the bulk water can be highly enriched in the jet drops ejected during bubble bursting, impacting global climate and public health. However, the detailed mechanism of this enrichment remains obscure, with the enrichment factor being difficult to predict. Here, we experimentally investigate the enrichment of nano/microsized particles in bubble bursting jet drops and highlight the underlying hydrodynamic mechanism, combining the effects of bubble scavenge and bursting on the transport of particles. Scaling laws for the enrichment factor are subsequently proposed that de-1

“…The aging process caused by UV light could alter the surface charge density and even the Hamaker constant of plastics, thus affecting their aggregation behavior in the environment [ 71 ]. Previous studies demonstrated that NPs could be transferred from the marine environment to the atmosphere by the rupture of bubbles on the sea surface and that the mobility of UV-aged PP-NPs was higher than that of incipient PP-NPs [ 72 ]. The photoaged MPs have a stronger migration ability and a larger cumulative flux ratio in the soil profile.…”

Microplastics (MPs) are ubiquitous in environmental media, and their harmful effects on MPs on the ecosystem have attracted more and more attention. Once released into the environment, MPs can trigger oxidative degradation through ultraviolet (UV) to cause photoaging. Photoaging significantly affects the properties of MPs, which leads to changing their environmental behaviors and increasing environmental risks. In this review, the generation of MPs under UV irradiation and the influence of environmental factors on the photoaging of MPs were discussed. Photoaging of MPs is an important process affecting the migration, transformation and interaction of pollutants in water and soil. In order to fully predict the fate and environmental interaction of MPs, more researches are needed in the future to explore the photoaging behavior of different types of MPs under natural environmental conditions.
