Background In epidemiology studies, ambient measurements of PM 2.5 are often used as
surrogates for personal exposures. However, it is unclear the degree to which ambient PM …

Exposure measurement error is an important source of bias in epidemiological studies. We
assessed the validity of employing ambient (outdoor) measurements as proxies of personal …

Personal monitoring for fine particulate matter (PM 2.5) was conducted for adults (48
subjects, 18–63 years of age) in Hong Kong during the summer and winter of 2014–2015 …

Luoyang is a typical heavy industrial city in China, with a coal-dominated energy structure
and serious air pollution. Following the implementation of the clean air actions, the …

Direct evidence about associations between fine particles (PM 2.5) components and the
corresponding PM 2.5 bioreactivity at the individual level is limited. We conducted a panel …

This study estimates infiltration factors (F inf) and ambient personal exposure factors (F pex)
for fine particulate matter (PM 2.5) in two Chinese megacities, and constructs predictive …

Concurrent ambient and personal measurements of fine particulate matter (PM 2.5) were
conducted in eight districts of Guangzhou during the winter of 2011. Personal-to-ambient …

Personal exposure and ambient fine particles (PM 2.5) measurements for 13 adult subjects
(ages 19–57) were conducted in Hong Kong between April 2014 and June 2015. Six to 21 …

Due to high-speed and extensive economic development, increasing urbanization, and
booming industry in China, there is a growing public concern over PM 2.5 pollution. The …

Epidemiological studies provide evidence of the harmful effects of source-specific fine
particulate matter (PM 2.5) on human health. Studies regarding relative contributions of …
