This document summarizes the progress made by the EPA Particulate Matter (PM) Centers during their first 6 years in identifying and understanding human exposures to PM air pollution since the mid-course report prepared in 2002 (Lippmann et al., 2003). When the PM Centers were designated in 1999, the primary body of evidence for personal and population-based exposures to ambient air PM consisted...

awma.org Copyright 2012 Air & Waste Management Association The organic fraction of fine particulate matter (PM2.5) can comprise a large fraction of total concentrations of PM across the United States.1 Typically, organic aerosol (OA) or organic particulate matter (OPM) has been viewed as primary and secondary in nature, referring to material that is directly emitted to the atmosphere or PM that...

conclusions in order to diminish the health impacts of particulate matter in khorramabad, health training for the public, especially for persons with chronic lung and heart diseases, the elderly, and children, should be conducted by health systems to encourage them to reduce their activities during dusty days. materials and methods the pm10 sampling was carried out with a high-volume sampler at...

Particulate matter (PM) in the atmosphere has diverse natural and anthropogenic sources, is a complex, heterogeneous mixture [...]

Domestic cooking is critical for release of particulate matter (PM) in indoor environments. This study tested low-cost sensors to assess PM from student studio flats different methods and establish the impact extractors.

BACKGROUND Although studies have documented the association between heart rate variability (HRV) and ambient particulate exposures, the association between HRV, especially at night, and metal-rich, occupational particulate exposures remains unclear. OBJECTIVE Our goal in this study was to investigate the association between long-duration HRV, including nighttime HRV, and occupational PM(2.5) ...

The development of gasoline direct injection (GDI) engines has provided a strong alternative to port fuel injection engines as they offer increased power output and better fuel economy and carbon dioxide emissions. However, particulate matter (PM) emission reduction from GDI still remains a challenge that needs to be addressed in order to fulfil the increasingly stricter environmental regulatio...

Both long-term and short-term exposure (one to two hours) to particulate matter are associated with morbidity and mortality caused by cardiovascular diseases. The underlying mechanisms leading to cardiovascular events are unclear, however, changes to blood coagulability upon exposure to ultrafine particulate matter (UFPM, the smallest of which can enter the circulation) is a plausible mechanism...

Automotive particulate matter (PM) causes deleterious effects on health and visibility. Physical and chemical properties of PM also influence climate change. Roadside remote sensing of automotive emissions is a valuable option for assessing the contribution of individual vehicles to the total PM burden. LiDAR represents a unique approach that allows measuring PM emissions from in-use vehicles w...
