Background: Particulate matter pollution has become a growing health concern over the past few decades globally. The problem is especially evident in China, where particulate matter levels prior to 2013 are publically unavailable. We conducted a systematic review of scientific literature that reported fine particulate matter (PM2.5) concentrations in different regions of China from 2005 to 2016...

The eruption of Mount St. Helens in Washington State on May 18th, 1980 resulted in a massive and unanticipated particulate air pollution shock. I use the incidence of the ash cloud fallout across Washington as a natural experiment to estimate the effect of a particulate shock on birth outcomes and infant mortality. I find that while there is no statistical effect on infant mortality, there were...

REFEREE #1 General comments: This paper presents a study of different components of air pollution at London Heathrow Airport in two periods covering warm and cold environmental conditions. The authors report measurements of both particulate and gaseous pollutants and use k-means clustering and positive matrix factorisation in an attempt to apportion measured pollution to emissions sources and p...

Abstract: This study built a model with DVI, which is computed by near-infrared and red bands of SPOT-5 image, and observed concentration of PM10 (inhalable particulate matter) to retrieve concentration of PM10 in SPOT-5 image of Beijing urban acquired in 2007. Spatial distribution trends of PM10 are basically identical between retrieved result and observed data. In 2007, inhalable particulate ...

A simultaneous study on indoor and outdoor particulate matter concentrations was done in five elementary schools in central parts of Tehran, Iran. Three sizes of particles including PM10, PM2.5 and PM1.0 were measured in 13 classrooms within this schools during winter (January, February and March) 2009. A laserbased portable aerosol spectrometer Model Grimm-1.108, was used for the continuous me...

OBJECTIVES We conducted a case-control study of adulthood asthma and point-source respirable particulate air pollution with asthma-diagnosed case patients (n = 3717) and gastroenteritis-diagnosed control patients (n = 4129) to determine effects of particulate air pollution on public health. METHODS We used hospitalization data from Buffalo, NY, neighborhoods for a 5-year period (1996 through ...
