The adverse effects of acidic ultrafine particles (AUFPs) have been widely recognized in
scientific communities. However, a handful of studies successfully acquired the …

Understanding the composition and sources of atmospheric ultrafine particles (UFPs) is
essential in evaluating their exposure risks. It requires long-term measurements with high …

Ultrafine particles (UFPs) dominate the particle number population in the urban atmosphere
and revealing their chemical composition is important. The thermal desorption chemical …

In this study, real time measurements of particle number size distribution in urban Gwangju,
coastal Taean, and industrial Yeosu in Korea were conducted in 2008 to understand the …

Developing countries, such as China, are facing serious air pollution issues due to fast
economic development. In this study, traffic related air pollutants, including number …

Ultrafine particle (UFP) pollution should be controlled to reduce its effects on health. The
design of control measures is limited owing to the uncertainty of source contributions in …

Ultrafine particles (< 100 nm in diameter, UFP) are known to be more toxic per unit mass
than larger particles and contribute to more than 90% in particle number concentrations in …

Ultrafine particles (UFPs or PM 0.1; aerodynamic diameter≤ 0.1 μm) were monitored at a
roadside site (RS) in a populated area of Hanoi, Vietnam. Meanwhile, UFPs and fine …

Ultrafine particles (UFPs) dominate the atmospheric particles in number concentration,
impacting human health and climate change. However, existing studies primarily rely on …

Ultra fine particles (UFP) cover the size range of both nucleation mode particles (NUC, D p<
25 nm) and Aitken mode particles (AIT, 25 nm< D p< 100 nm), and play important roles in …
