Background: Air pollution, especially the phenomenon of dust and particulate matter can cause mortality of many civilians, and causes various diseases including cardiovascular and respiratory diseases. One of the major pollutants in the air is particulate matter that concentration has increased over recent years. So, present study with aim of Quantification Health Endpoints Attributed to partic...
BACKGROUND Although air pollution's short-term effects are well understood to be marked and preventable, its acute neuropsychological effects have, to our knowledge, not yet been studied. We aim to examine the association between daily variation in traffic-related air pollution and attention. METHODS We conducted a follow-up study from January 2012 to March 2013 in 2,687 school children from ...
Fine particulate matter air pollution plus ozone impairs vascular function and raises diastolic blood pressure. We aimed to determine the mechanism and air pollutant responsible. The effects of pollution on heart rate variability, blood pressure, biomarkers, and brachial flow-mediated dilatation were determined in 2 randomized, double-blind, crossover studies. In Ann Arbor, 50 subjects were exp...
Clear association exists between ambient PM₁₀ concentrations and adverse health outcomes. However, determination of the strength of associations between exposure and illness is limited by low spatial-resolution of particulate concentration measurements. Conventional fixed monitoring stations provide high temporal-resolution data, but cannot capture fine-scale spatial variations. Here we examine...
Smoking Policies Tighten in Halls of Academe As the fall 2012 semester gets under way, at least 744 U.S. colleges and universities have made their campuses completely smoke free, indoors and out, and nearly threequarters of those have banned all forms of tobacco on campus. Ty Patterson, executive director of the National Center for Tobacco Policy, told the Christian Science Monitor that many co...
BACKGROUND Recent evidence suggests that long-term exposure to particulate air pollution contributes to pulmonary and systemic oxidative stress, inflammation, progression of atherosclerosis, and risk of ischemic heart disease and death. Short-term exposure may contribute to complications of atherosclerosis, such as plaque vulnerability, thrombosis, and acute ischemic events. These findings are ...
Types of available studies relevant to the quantification of air pollution health effects and their principal limitations are discussed. Assessments are provided based on review and re-analysis of previously reported data bases, synthesis of published findings, and original analysis of health data sets using new methods or recent size-specific particle mass measurements. Interim results from on...
BACKGROUND AND PURPOSE The aim of the study was to assessed the impact of short-term exposure to air pollution on ischemic stroke subtype, while focusing on stroke caused via cardioembolism. METHODS From a nationwide, multicenter, prospective, stroke registry database, 13 535 patients with acute ischemic stroke hospitalized to 12 participating centers were enrolled in this study. Data on the ...
BACKGROUND/AIMS Although indoor air pollution is a well-known risk factor for tuberculosis (TB), the possible link between outdoor air pollution and TB development has not been examined fully. We assessed the impact of outdoor air pollution on TB development in the Seoul metropolitan area, South Korea. METHODS The mean concentrations of ambient particulate matter (PM) with an aerodynamic diam...
