“…The number of AMPs in Bandung and Osaka decreased as the size of the physical diameter of AMPs increased. This is in accordance with AMPs research in Wenzhou, which shows that the number of AMPs decreases as the size of the physical diameter of AMPs increases with the majority of AMPs having a physical diameter < 30 μm [40] AMPs research in Beijing also shows that the number of AMPs decreases as the physical diameter of AMPs increases with the majority of AMPs having a physical diameter between 20 -100 μm [46].…”

Plastic is a material that is widely used in everyday life. It can be degraded into small-sized fragments (< 5 mm) called microplastics (MPs). Research on MPs has primarily focused on the aquatic environment, while studies on airborne MPs (AMPs) are still in their early stages. In this study, AMPs at two locations (Bandung (Indonesia) and Osaka (Japan)) were characterized by attenuated total imaging and micro-Fourier transform infrared spectroscopy, as a preliminary study. The concentrations of AMPs in total suspended particulates (TSP) in Bandung and Osaka ranged from 1.03 to 14.27 particles/m3 and from 0.63 to 3.29 particles/m3, respectively. AMPs in both locations were fragmented, with dominant Feret diameters ranging from 1 to 20 μm.

“…An LDIR (Agilent 8700) analyzer was used to detect MPs in soil samples (Liu et al, 2022). The 8700 LDIR laser infrared imaging system uses a quantum cascade laser as the light source; the energy is more than 10,000 times that of the traditional Fourier transform microinfrared/infrared imaging system.…”

The microplastics (MPs) formed by broken plastic film may migrate in the soil under drip irrigation. To investigate the migration distribution of MPs in desert farmland soil under drip irrigation conditions, our study was conducted on farmland in Xinjiang (China). A MP drip irrigation penetration migration testing device was set up in combination with Xinjiang farmland irrigation methods to conduct a migration simulation experiment. The results showed that the migration amount of MPs in soil was significantly positively correlated with the amount of drip irrigation, and significantly negatively correlated with the soil depth; in addition, the relationship between the migration amount of MPs in different types of soil was: clay < sandy loam < sandy soil. Under drip irrigation conditions, the migration rates of MPs were 30.51%, 19.41%, and 10.29% in sandy soil, sandy loam soil, and clay, respectively. The migration ability of these three particle sizes of polyethylene MPs in soil was ranked as follows: 25 to 147 μm > 0 to 25 μm > 147 to 250 μm. When the drip irrigation volume was 2.6 to 3.2 L, horizontal migration distances of MPs exceeded 5 cm, and vertical migration distances reached more than 30 cm. Our findings provide reference data for the study of soil MP migration. Environ Toxicol Chem 2024;00:1–10. © 2024 SETAC

“…Deposited particles are collected by rinsing the device with ultrapure water and filtering. Some studies collect the deposited dust over a clean glass Petri dish [51,53,65,75] or in specific areas using bristle brushes and metal dustpans [57,58,73] or a vacuum cleaner [93,94]. In addition, plant leaves [86] and spider nets [54] are also used as samplers for atmospheric MPs deposition studies.…”

“…The deposition area is essential in calculating the number of MPs atmospheric deposition per unit area [34,41]. For deposited dust, the MPs abundance is measured in units per gram of dust fall [36,57,58,73].…”

Micro- and nanoplastics (MNPs) are an important atmospheric aerosol constituent. However, there still needs to be a standard procedure for their sampling and size fractionation, which is an obstacle to the aggregation and critical analysis of results obtained by different research groups. This review focuses on the sampling and fractionation methodologies used for MNPs. Moreover, a streamlined, simplified methodology for sampling and fractionation is proposed.
