Prior studies reported excess rates (ERs) of cardiorespiratory events associated with short-
term increases in PM 2.5 concentrations, despite implementation of pollution-control …

Ultrafine particles (UFP, those with diameters≤ 100 nm), have been reported to potentially
penetrate deeply into the respiratory system, translocate through the alveoli, and affect …

There is a body of evidence that ultrafine particles (UFP, those with diameters≤ 100 nm)
might have significant impacts on health. Accordingly, identifying sources of UFP is essential …

During the past two decades, efforts have been made to further reduce particulate air
pollution across New York State through various Federal and State policy implementations …

This study assessed the effects of policy implementations and economic drivers on the
identified sources of particulate pollution and their contributions to the ambient PM 2.5 …

Abstract Since the Clean Air Act amendments of 1970, various efforts have been made in the
United States to control ambient particulate matter and improve air quality. Although …

Background The spatiotemporal and demographic disparities in exposure to ultrafine
particles (UFP; number concentrations of particulate matter (PM) with diameter≤ 0.1 μm), a …

Abstract The PM 2.5-bound visibility improvement remains challenging in China despite
vigorous control on anthropogenic emissions in recent years. One critical issue could exist in …

The study measured and analysed the particle number concentration of particles ranging
from 10 to 800 nm in urban and background sites. The aim of the study is to estimate the role …

In this paper, we applied the Dispersion Normalised Positive Matrix Factorisation (DN-PMF)
approach recently proposed in the literature to provide a more realistic picture of the relative …
