The harm of fine particulate matter (PM2. 5) to public health is the focus of attention around
the world. The Global Burden of Disease (GBD) Study 2015 ranked PM2. 5 as the fifth …

Several epidemiologic and toxicological studies have commonly viewed ambient fine
particulate matter (PM2. 5), defined as particles having an aerodynamic diameter of less …

Recently, many researchers paid more attentions to the association between air pollution
and respiratory system disease. In the past few years, levels of smog have increased …

Epidemiological studies have associated high levels of airborne particulate matter (PM) with
increased respiratory diseases. In order to investigate the mechanisms of air pollution …

Air pollution is a very critical issue worldwide, particularly in developing countries.
Particulate matter (PM) is a type of air pollution that comprises a heterogeneous mixture of …

Abstract Atmospheric particulates, especially PM2. 5, not only damage the respiratory
system, but also play important roles in pulmonary immunity. China is influenced by …

Background Ambient particulate matter (PM) exposure has been associated with respiratory
function decline in epidemiological studies. We hypothesize that a possible underlying …

The association between airborne fine particulate matter (PM 2.5) concentration and the risk
of respiratory diseases has been well documented by epidemiological studies. However, the …

Respiratory diseases caused by ambient air pollution are a contributing factor to prolonged
bronchial inflammation leading eventually to hyper-activation of innate immune system …

Airborne fine particulate matter (PM 2.5) attracts more and more attention due to its
environmental effects. The immune system appears to be a most sensitive target organ for …
