Diesel exhaust inhalation elicits acute vasoconstriction in vivo

Traffic-related air pollution is consistently associated with cardiovascular morbidity and mortality. Recent human and animal studies suggest that exposure to air pollutants affects vascular function. Diesel exhaust (DE) is a major source of traffic-related air pollution. The goal of this particular study was to study the effects of short-term exposure to DE on vascular reactivity and on mediators of vascular tone.
