Effects of particulate matter from air pollution on cardiovascular system of the body

Abstract

Air pollution is a mixture of particulate and gaseous components, which will have adverse effects on human health. Depending upon Cause of air pollution, composition varies, and studies from all over the world shown that air pollution has increased mortality. More than gaseous components, particulate matter has greater impact on health, which is proved by serval clinical studies. Particulate components have wide effect on human health especially cardiovascular system of the body. There is increased risk of death from both chronic and acute exposure to PM air pollution. Acute exposure had led to wide range of cardiovascular events like hospital admissions with angina, heart failure, myocardial infraction. Long term exposure led to risk of death from coronary heart disease. Particulate matter from air pollution has been also shown as important factor contributing to obesity and diabetes. An understanding of how PM causes toxic effects on human health is important to prevent and minimize the health effects. Public health problems and mortality rate because of air pollution are expected to double by 2050.In this paper we will review how PM exerts toxic effects on cardiovascular system, and discuss about major studies that established link between particulate matter (PM) air pollution and cardiovascular disease in the humans.
