Epidemiological studies suggest that there may De adverse human health effects associated with exposure to ambient fine particles (PM). in a preliminary study, we examined the health Effects of. Air pollution is a major challenge to public health. Ambient fine particulate matter (PM) is the key component for air pollution, and associated with significant majority of the mortality following PM exposure is related to cardiovascular diseases. However, the mechanisms for the adverse effects of PM exposure on cardiovascular system remain largely unknown and under active Cited by: Health effects: During the past 10 years many new epidemiological and toxicological studies on health effects of particulate matter (PM) have been published. In summary, long-term exposure against PM for years or decades is associated with elevated total, cardiovascular Cited by: University at Albany, State University of New York, Albany, NY, United States Interests: effects of particulate matter on daily morbidity and mortality due to cardiovascular and pulmonary diseases in urban centers; chemical characteristics of fine particles responsible for the observed health effects; exposure and health impacts related to indoor and outdoor air pollution including studies of.
Abstract. There is a large body of community-level epidemiologic evidence showing positive associations between increases in morbidity and mortality from respiratory and cardiovascular causes, and increases in the mass of ambient particulate matter (PM) in air in the preceding 1–3 days (Dockery and Pope ; Schwartz and Morris ; Laden et al. ). However, to run a HIA for ambient air particles is extremely complex and has been suffering from a considerable lack of knowledge on the following: 1) particle composition; 2) mechanistic toxicological insight in particle components causally responsible for cardio-respiratory health effects; 3) airway deposition data for various particle size. Introduction. Air pollution, and especially traffic-derived particulate matter , is now established as a major cause of cardiorespiratory morbidity and mortality .Epidemiological studies have shown that chronic air pollution exposure is associated with the degree of atherosclerosis [5,6], and the risk of cardiovascular events .Acute exposure causes exacerbation of existing.

The cardiovascular effects of air pollution came to prominence in the early s. In , Dockery and colleagues examined the relationship between PM and hospital admissions/deaths from cardiovascular disease in six North American cities with broadly similar demographics .They found a strikingly linear relationship between levels of PM and cardiovascular . Alterations in Vascular Reactivity After Particulate Matter Exposure. The term particulate matter (PM) broadly refers to a heterogeneous mixture of airborne particles that are suspended in the air (Schlesinger ). PM arises from numerous sources and is a significant component of the national ambient air pollution burden (United States. Introduction. Air pollution is a major challenge to public health. Ambient particulate matter (PM) is the key component for air pollution. A recent Global Burden of Disease Study showed that PM exposure is responsible for million deaths per year and 76 million years of healthy life lost ulate matter exposure could be especially a major health problem in the developing countries .
