PM2.5 into carcinogenic virus "downwind car" Beijing lung cancer incidence rate increased four times times 30

Beijing scenery, thousands of miles hazy, miles of dust floating, looking at the three rings inside and outside, thick fog, the bird's Nest up and down, the haze surging! A "Qinyuanchun Haze" is a "horror" of air pollution, and when you face the invisible particles in the eyes of the naked eye, do you realize that their "small stature" actually has "great harm"? 26th, the "Indoor environment and Health Appliances Seminar" held by Jingdong (JD.com) group was held in Beijing, He Huan, a professor of respiratory science at Peking University's People's Hospital, showed the public the three big strokes of PM2.5, The Invisible "killer", in his speech. PM2.5 is a particulate matter in the atmosphere that is less than or equal to 2.5 microns in diameter and is also known as a lung particulate matter. Its diameter is less than 1/20 of the weight of human hair, but through the body's respiratory system, PM2.5 can be stranded in the sensitive respiratory tract, causing local obstruction and inflammation. In addition, because of the uneven surface of the PM2.5, often become toxic ions, pathogenic virus "downwind", into the human body carcinogenic. Data show that the incidence of lung cancer in Beijing in the past 30 years increased by more than four times times, which is directly related to air pollution. At the same time, He Huan also pointed out that PM2.5 not only affect the lungs, through the exchange of blood, PM2.5 particles can also enter the blood vessels, induce cardio-cerebrovascular diseases. Professor Ho said that smoking and improper cooking is the main "production" of indoor PM2.5, therefore, residents in response to these invisible "killer", not only in the choice of healthy home appliances, "the right medicine", but also in the habit of living "clean". Coincidentally, in 2013, to air purifiers, humidifier, and so on the main Beijing-East health appliances sales also confirmed the professor He's point of view, Jingdong data show that 2013, the number of consumers to buy healthy home appliances reached 9 million, compared with 2012 growth of about 70%.
