Residential wood combustion is the main source of elevated concentrations of fine particulate matter (PM2.5) during winter in many towns of Tasmania, Australia. A commercially available firebox catalyst in Australia has previously been shown to reduce visible smoke emissions and the manufacturer reports reductions in particle emissions generated from individual wood heaters in laboratory settin...
High-temperature, controlled incineration and thermal treatment of contaminated soils, sediments, and wastes at Superfund sites are often preferred methods of remediation of contaminated sites under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 and related legislation. Although these methods may be executed safely, formation of toxic combustion or reaction by...
Epidemiological studies show a strong association between exposure to air pollution – and particularly particulate matter (PM) -, increased prevalence of Multiple Sclerosis (MS) higher rates hospital admissions for MS relapses. Besides having immunomodulatory effects sustaining systemic oxidative-inflammatory response, PM may participate in pathogenesis by targeting also Central Nervous System ...
BACKGROUND Blood pressure (BP) may be implicated in associations observed between ambient particulate matter and cardiovascular morbidity and mortality. This study examined cross-sectional associations between short-term ambient fine particles (particulate matter <or= 2.5 microm in aerodynamic diameter; PM(2.5)) and BP: systolic (SBP), diastolic (DBP), mean arterial (MAP), and pulse pressure (P...
A number of epidemiological studies have shown a strong association between exposure to ambient airborne particulate matter (PM 2.5, PM < 1.0) and lung or cardiovascular diseases characterised by high mortality and morbidity. However, much less is known about the role of air pollution in the pathogenesis of autoimmune diseases, which constitutes a significant problem in modern society. This pap...
RATIONALE Although substantial scientific evidence suggests that chronic exposure to ambient air pollution contributes to premature mortality, uncertainties exist in the size and consistency of this association. Uncertainty may arise from inaccurate exposure assessment. OBJECTIVES To assess the associations of three types of air pollutants (fine particulate matter, ozone [O3], and nitrogen di...
It is estimated that more than two-thirds of air pollution-related deaths are due to cardiovascular causes. Significant studies have now indicated exposure urban pollutants known be a source oxidative stress and inflammation causes disease. Nitrogen oxides, Particulate Matter (PM) such as coarse particle (PM10, PM <10μm), fine particles (PM2.5, <2.5μm) Ultra-Fine Particles (UFPs or PM0.1,...
