Background and aims A wide variety of adverse health effects on both fetuses and neonates have been ascribed to particulate matter (PM) air pollution. Recent evidence suggests that PM exposure results in increased oxidative and nitrosative stress. In the ENVIRONAGE birth cohort, we investigated the association of placental 3-nitrotyrosine (3-NT) with PM exposure during various time windows of p...

Currently residential wood combustion (RWC) is increasing in Europe because of rising fossil fuel prices but also due to climate change mitigation policies. However, especially in small-scale applications, RWC may cause high emissions of particulate matter (PM). Recently we have developed a new high-resolution (7×7 km) anthropogenic carbonaceous aerosol emission inventory for Europe. The invent...

The rate of consumption of dithiothreitol (DTT) is increasingly used to measure the oxidative potential of particulate matter (PM), which has been linked to the adverse health effects of PM. While several quinones are known to be very reactive in the DTT assay, it is unclear what other chemical species might contribute to the loss of DTT in PM extracts. To address this question, we quantify the...

The biological effects of acute particulate air pollution exposure in host innate immunity remain obscure and have relied largely on in vitro models. We hypothesized that single acute exposure to ambient or engineered particulate matter (PM) in the absence of other secondary stimuli would activate lung dendritic cells (DC) in vivo and provide information on the early immunological events of PM ...

Particulate matter derived from various sources of fuel combustion contains minor to trace amounts of Fe-oxides that can be detected by magnetic measurements. These magnetic particulates can be used as proxies for particulate pollution, since oxide contents are often larger in amounts and may have distinctive magnetic properties, compared to most types of natural dusts. Magnetic particulates ra...

Background & Aims of the Study: Particulate matters less than 10 microns can absorb into your lungs and reacting with the moisture and enter the circulatory system directly through the airways. The aim of this study is to assess Behavior PM 10 data in different seasons and Determination effects on human health in Ahvaz city during 2013. Materials & Methods: Data Particulate matters less than 10...

To investigate the levels of particulate pollution in residential built environments measurements of PM(10), PM(2.5), and PM(1) and concentrations were made between 2004 and 2008 in various residencies in a UK suburban location. Measurements were carried out in three different residential settings (Types I, II and III). In type I non-smoking living rooms, the highest 24-hour mean concentrations...

The purpose of the Enhanced Particulate Matter Surveillance Program was to provide scientifically founded information on the chemical and physical properties of dust collected over a period of approximately 1 year in Djibouti, Afghanistan (Bagram, Khowst), Qatar, United Arab Emirates, Iraq (Balad, Baghdad, Tallil, Tikrit, Taji, Al Asad), and Kuwait (northern, central, coastal, and southern regi...

The Chinese government has moved aggressively since 2005 to reduce emissions of a number of pollutants including primary particulate matter (PM) and sulfur dioxide (SO(2)), efforts inadvertently aided since late 2008 by economic recession. Satellite observations of aerosol optical depth (AOD) and column nitrogen dioxide (NO(2)) provide independent indicators of emission trends, clearly reflecti...
