New inventions always knocking us with new challenges even though such findings use to carry new hopes and learn make some useful tools. As all we are known the cost of pollution that world has to pay but reality is, pollution is not such products which piled apart from human. Moreover, we know among many sorts of pollution, air pollution is one most determinants directly to heart health. This has become more visible from recently published findings of new studies on air pollution and human heart. And have shown supporting gadget for heart attack or stroke by 5% to 34%. The study was conducted by Dr. Hazrije Mustafic and his team. Same studies which carried previously were not so conclusive regarding the heart related issues.
Major findings stated ahead, people those who gets exposed to higher levels of particulates and polluting gases, which include carbon monoxide, nitrogen dioxide and sulfur dioxide, were anywhere from 0.5% to 5% more likely to experience a heart attack on the day of that exposure or on the following day. The risk for healthy people may be relatively low but consider that unlike other factors that contribute to heart disease such as smoking, high blood pressure and high cholesterol almost everyone breathes polluted air unknowingly. To measure the link between air quality and stroke risk researchers looked at patients who were admitted with stroke at Beth Israel Deaconess Medical Center between 1999 and 2008 and then correlated their hospital admissions with fine particulate readings from the Harvard School of Public Health’s ambient air monitoring station, located near the hospital campus and within 13 miles of 90% of the stroke patients’ homes. According to the data, the risk of stroke was 34% higher after a 24-hour period of moderate air quality, in which concentrations of fine particulates measured 15-40 micrograms per cubic meter of air, compared with periods following a day of good air quality, in which the particulate concentration was less than 15 micrograms per cubic meter of air. Peak stroke risk occurred at about 12 hours after exposure to moderate quality air. Wellenius and his colleagues also found that the danger was greatest for those exposed to black carbon and nitrogen dioxide (NO2), both emitted from fuel-burning car engines. Previous studies have found that short-term exposure to NO2 can trigger respiratory problems, including inflammation in the airways, in healthy people, and that concentrations of NO2 are anywhere from 30% to 100% greater near roads than away from roadways.
The air pollution is also found major underlying cause behind cognitive impairment aged women. Such a conclusion drawn from data of more than 19000 U.S women age rank from 70 to 81and respondents were taken from variety of geographical information about pollution levels. The researcher mentioned that the first study to look at the effects of small as well as large particles in the ambient air and found that exposure to both small and large particulates was associated with sizable cognitive losses. On which basis , the study concluded that if their findings are borne out through further research, reducing particulate air pollution might emerge as a means of lessening the burden of cognitive impairment and dementia of old women.
Among many other burning issues related to human creature air pollution is on top. And growing industrial installation in developing countries, growing nuclear stations in developed countries as well as world wide deforestation are major causes of air pollution. Further more, people from least developing countries are suffering due to lack of proper awareness on the air pollution and tools to take precautions on it too.
