Air Pollution Affecting the Health of People: Cardiovascular Diseases

Abstract

Air emissions, like nitrogen dioxide and ozone, consists of particulate matter (PM) and gaseous contaminants. PM is graded into coarse particles (PM10), fine particles (PM2.5) and ultrafine particles according to dimension. Epidemiological and laboratory trials investigating the physiological effects of ambient air emissions are planned to offer an original analysis of the empirical facts. Pooled epidemiological trials indicated that a rise of 10 μg/m3 in long-term PM2.5 exposure was correlated with an elevation in cardiovascular mortality of 11 percent. Increased coronary death was also attributed to exposures to nitrogen dioxide in the long term and short term.As demonstrated by premature aortic and coronary calcification, susceptibility to air pollution and road traffic has been linked with an expanded danger of arteriosclerosis. The higher risk of myocardial infarction, strokes and severe heart disease has been linked with short-term changes in air contamination. The risk rose even though the concentrations of toxins remained below European levels.
