ClearInsight into the size-resolved markers and eco-health significance of microplastics from typical sources in northwest China
Researchers characterized airborne microplastics and plasticizers emitted from five common sources in northwest China—plastic burning, fruit bag burning, road traffic, agricultural film, and livestock breeding—finding source-specific polymer and chemical profiles in PM2.5 and PM10 fractions.

Researchers characterized microplastic source profiles and plasticizer emissions (phthalates, benzothiazoles, bisphenol A) from five pollution sources (plastic burning, traffic, agricultural film, livestock) in PM2.5 and PM10 aerosols across the Guanzhong Plain in northern China, providing source-resolved atmospheric microplastic data.
Plastic burning: An important global source of atmospheric nanoplastic particles
Researchers conducted smoldering laboratory experiments with PVC, PP, LDPE, PET, and PS plastics and used aerosol mass spectrometry to characterise the physical and chemical properties of nanoplastic particles emitted, finding that plastic burning generates large quantities of nanoplastics and thermo-oxidation products that represent a significant but poorly quantified global source of atmospheric nano-sized plastic particles.

This study quantified suspended atmospheric microplastics across eight land use types in Lanzhou, northwest China, finding a mean abundance of 4.5 particles/m³ with peaks in industrial and residential areas. Land use type was the strongest predictor of MP concentration, highlighting urban and agricultural activities as key emission drivers.
Atmospheric Microplastics Emission Source Potentials and Deposition Patterns in Semi‐Arid Croplands of Northern China
Researchers measured atmospheric microplastic emissions from croplands in semi-arid northern China, where wind erosion events are common. They found that fiber-shaped particles dominated airborne microplastics and that concentrations increased significantly when air masses passed over cropland surfaces. The study reveals that agricultural land in dry regions may be an underrecognized source of airborne microplastic pollution.

Airborne Micro- and Nanoplastics: Source Implications from Particulate Matter Composition
Researchers simultaneously measured airborne micro- and nanoplastics (AMNPs) and particulate matter (PM) across three sites in Japan in different seasons, identifying shared and distinct sources. AMNPs co-occurred with combustion-related PM components, providing evidence that airborne plastics partly originate from the same sources as fine particulate air pollution.
Microplastic atmospheric dustfall pollution in urban environment: Evidence from the types, distribution, and probable sources in Beijing, China
Researchers collected atmospheric dustfall samples across urban Beijing and analyzed the types, distribution, and likely sources of airborne microplastics. They found that synthetic fibers from textiles and fragments from various plastic products were the dominant forms, with concentrations varying by location and proximity to pollution sources. The study provides evidence that urban atmospheric microplastic pollution is widespread and likely linked to daily human activities and industrial processes.
Supplementary material to "Insight into the size-resolved markers and eco-health significance of microplastics from typical sources in northwest China"
Researchers provided supplementary data on pyrolysis products used to identify and characterize microplastics by size from typical pollution sources in northwest China, supporting a larger study on the environmental and health significance of different microplastic size fractions. This type of chemical fingerprinting helps determine where microplastics come from and how they break down in the environment.
Spatiotemporal distribution and potential sources of atmospheric microplastic deposition in a semiarid urban environment of Northwest China
Atmospheric microplastic deposition in a semiarid urban environment in northwest China ranged from 79.5 to 810.0 particles per square meter per day, with peak deposition in summer, fibres and fragments dominating, and source analysis pointing to local plastic products and waste as primary contributors.

Atmospheric sampling at two sites in a Chinese coastal city found microplastics suspended in the air at both downtown and industrial locations, but with different dominant sources — lifestyle and consumer products in the city center versus industrial activity in the industrial zone. The finding that microplastics are transported through the atmosphere confirms that people in urban areas are inhaling plastic particles regardless of proximity to industrial facilities.
