Study on the Physical and Chemical Characteristics and Sources of Atmospheric Single Particles in Weifang During the 2022 Winter Olympic Games and the Winter Paralympic Games
Summary
Researchers analyzed atmospheric particulate matter in a Chinese city during the 2022 Winter Olympics to evaluate whether special air quality protection measures were effective. The study found that pollution control measures during the event reduced certain types of particles, demonstrating that targeted policy interventions can temporarily improve urban air quality.
In order to evaluate the effectiveness of air quality assurance measures during the 2022 Beijing Winter Olympic Games and the Winter Paralympic Games, samples of atmospheric particulates in Weifang City during the 2022 Winter Olympic Games and the Winter Paralympic Games were collected to analyze the level of air pollution during the Winter Olympic Games and the Winter Paralympic Games.The computer-controlled scanning electron microscopy and energy spectrum system (CCSEM-EDX) was used to analyze the morphology characteristics of particulates, the type and quantity proportion of particulates, and the quantity-particle size distribution of particulates.The results show that the air quality during the 2022 Winter Olympic Games and the Winter Paralympic Games is better than that in the same historical period of 2020 and 2021, the control measures are effective.

Compositions, Sources, and Aging Processes of Aerosol Particles during Winter Hazes in an Inland Megacity of NW China
Researchers characterized aerosol particles during winter haze events in Xi'an, China, identifying complex mixtures of organic compounds, heavy metals, and other pollutants. The unique local geography concentrates these airborne particles, contributing to the city's severe air quality problems.
Comparative study on physicochemical characteristics of atmospheric microplastics in winter in inland and coastal megacities: A case of Beijing and Shanghai, China
Researchers compared airborne microplastic pollution during winter in Beijing, an inland city, and Shanghai, a coastal city in China. They found notable differences in the shapes, sizes, and polymer types of microplastics between the two cities, reflecting their distinct urban and industrial environments. The study provides evidence that local geography and economic activity significantly influence the characteristics of atmospheric microplastic contamination.
Atmospheric microplastics in Handan, China: characteristics, seasonal variations, and human exposure risk
Researchers conducted a year-long monitoring campaign of deposited and suspended atmospheric microplastics in Handan, an industrial city in northern China. They found strong seasonal variations linked to wind patterns and industrial emissions, with human inhalation exposure posing a measurable health risk.
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.
Abundance of microplastics and nanoplastics in urban atmosphere
Scientists measured microplastics and nanoplastics in the air of two major Chinese cities and found concentrations reaching hundreds of thousands of particles per cubic meter. Road dust being kicked up by traffic and rainfall washing particles out of the sky were the two biggest drivers of atmospheric plastic pollution. These findings suggest that city residents are inhaling significant amounts of plastic particles every day, with potential implications for respiratory and overall health.
