TOXICOLOGICAL HIGHLIGHT Cardiovascular Toxicity of Inhaled Ambient Particulate Matter
The key unanswered question in the particulate matter (PM)related health concern is the biological plausibility of the association between PM and the observed adverse cardiopulmonary health effects. These adverse health outcomes have been demonstrated by both cross-sectional and time-series epidemiological studies. Key to the validity of the biological plausibility is the need to identify the c...
متن کاملHormesis 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 کاملEffects of metals within ambient air particulate matter (PM) on human health.
We review literature providing insights on health-related effects caused by inhalation of ambient air particulate matter (PM) containing metals, emphasizing effects associated with in vivo exposures at or near contemporary atmospheric concentrations. Inhalation of much higher concentrations, and high-level exposures via intratracheal (IT) instillation that inform mechanistic processes, are also...
متن کاملBioassay of extracts of ambient particulate matter.
Organic extracts from airborne particles collected at various sites in Scandinavia have been tested for mutagenicity in the Ames Salmonella/microsome assay. Extracts from particles in the respirable size fraction (diameter less than 3 microns) were mutagenic with and without metabolic activation. The mutagenic activity varied from day to day, mainly due to variations in meteorological parameter...
متن کاملEvaluation of the Pulmonary Toxicity of Ambient Particulate Matter From Camp Victory, Iraq.
Anecdotal reports in the press and epidemiological studies suggest that deployment to Iraq and Afghanistan may be associated with respiratory diseases and symptoms in U.S. military personnel and veterans. Exposures during military operations were complex, but virtually all service members were exposed to high levels of respirable, geogenic dust. Inhalation of other dusts has been shown to be as...
