“…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.…”

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.

“…Most studies have shown that bers are the main shape of microplastics in regions, such as Dongwan, China (Cai, et al, 2017), Yantai, China (Zhou, et al, 2017), London, UK (DRIS, et al, 2017), and Paris, France (Wright, et al, 2020). However, the results of studies in Hamburg, Germany (Klein, et al, 2019), the Niulibis Mountains in France (Allen, et al, 2019), and Beijing, China (Liu, et al, 2022), showed that fragments is dominant. This difference may be due to the differences in microplastic products in different regions.…”

Atmospheric microplastics is a key contributor to environmental contamination in aquatic and terrestrial systems, posing potential ecological risks. However, studies on atmospheric microplastics are still limited in urban regions of the Tibetan Plateau, a sentinel region to climate and environmental change under the warming climate. Based on samples of suspended atmospheric microplastics (SAMPs) in Lhasa City collected during the Tibetan New Year in February 2023, the occurrence, potential ecological risk of atmospheric microplastics were investigated. The results showed that the average abundance of microplastics in the atmospheric environment of Lhasa was 7.15 ± 2.46 ietms·m− 3.The sizes of detected microplastic ranged from 20.34 µm to 297.18 µm, with approximately 87% smaller than 100 µm. Fragmented microplastics (95.76%) were the dominant format, followed by fibers (3.75%), and pellets (0.49%), respectively. The primary polymer chemical components identified were polyamide (PA,68.73%) and polystyrene (PS,16.61%), respectively. According to the analysis of meteorological data and backward trajectory model, the trajectory of the air mass in Lhasa is obviously westward, and the atmospheric microplastics mainly come from the long-distance transmission of the atmosphere. The results of potential ecological risk index (PERI) assessment indicated that the atmospheric microplastic pollution in Lhasa was at a low level. This study provides valuable insights and a scientific foundation for future research on the prevention and control of atmospheric microplastic pollution in Lhasa and other ecologically sensitive cities.
