Hormesis for fine particulate matter (PM 2.5).
The hypothesis of hormesis - that substances that harm health at high exposures can reduce risks below background at low exposures, e.g., if they activate defenses without overwhelming them - becomes important for practical policy making if it holds for regulated substances. Recently, the U.S. EPA concluded that reductions in ambient concentrations of fine particulate matter (PM2.5) in air caus...

متن کاملPM Exposure Assessment Research: Supplement to Accomplishments of the Particulate Matter (PM) Centers (1999-2005)
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...
متن کاملUrban particulate matter (PM) suppresses airway antibacterial defence
BACKGROUND Epidemiological studies have shown that urban particulate matter (PM) increases the risk of respiratory infection. However, the underlying mechanisms are poorly understood. PM has been postulated to suppress the activation of airway epithelial innate defence in response to infection. METHODS The effects of PM on antibacterial defence were studied using an in vitro infection model. ...
متن کاملChemical Speciation of Particulate Matter Pollution in Urban Dhaka City
Dhaka, the capital and largest city of Bangladesh, lacks a regular air pollution monitoring network to measure and assess ambient air pollution level. Several academic and research projects attempted to measure a limited number of air pollutants near roadways in the central business district. These studies revealed that ambient concentrations of lead, benzene, particulate matter, carbon monoxid...
