Characterization of respiratory exposure to and effects of cold-air hyperventilation in guinea pigs.

abstract：BACKGROUND:Increases in particulate matter less than 2.5 µm (PM(2.5)) in ambient air is linked to acute cardiovascular morbidity and mortality. Specific components and potential emission sources of PM(2.5) responsible for adverse health effects of cardiovascular function are unclear. METHODS:Spontaneously hypertensive...
