World Health Organization: haze is a carcinogen
October 17, World Health Organization under the IARC released a report, for the first time to identify the atmospheric pollution carcinogenic to humans, and sees it as widespread and major environmental carcinogens. However, although air pollution as a whole carcinogenic factors have been proposed, it may be the result of damage to the human body contains several major pollutants by simultaneously acting.
1, PM2.5 (diameter less than or equal to atmospheric particulate matter 2.5 microns) Carcinogenicity / toxicity index: 5 stars
In 2010, the outdoor air particulate pollution as the world's seventh leading cause of death, China's fourth largest cause of death, more than 300 million people worldwide die from the pollution caused by various diseases, which China has 1.23 million people died, more than 2400 people Life Lost. There are nearly two million premature deaths and other particles PM2.5 pollution annually. Even in the EU, due to exposure to PM2.5 produced by human activities, the average life expectancy is 8.6 months. Its human impact is greater than any other contaminants.
2, PM10 (atmospheric diameter less than or equal to 10 micron particles) Carcinogenicity / toxicity index: 4 stars
PM10 PM2.5 in addition to containing such fine particulate matter, further comprising particles having a diameter of between 2.5 microns and 10 microns, some of these particles deposited in the upper airway, or into deep portion of the respiratory tract, but can not enter the bronchioles and alveoli , it is less harmful levels of PM2.5, but still a major hazard to air pollution.
3, the ozone
Carcinogenicity / toxicity index: 3 stars
70 million people die each year worldwide due to respiratory diseases caused by ozone. Several European studies have reported that exposure to ozone for each additional 10μg / m3, the daily mortality rises by 0.3%, 0.4% increase in heart disease. Currently, it is one of Europe's most air pollutants of concern.
4, nitrogen dioxide
Carcinogenicity / toxicity index: 2 stars
Epidemiological studies have shown that symptoms of bronchitis in asthmatic children increase in association with long-term exposure to NO. Increase the current number of cities in Europe and North America reduced lung function is also linked to the current measured (or observed) related to the concentration of nitrogen dioxide.
5, sulfur dioxide
Carcinogenicity / toxicity index: 2 stars
Studies have shown that higher sulfur dioxide levels in the air of the day, go to the hospital because of heart disease who increased mortality rate increased. Sulfur dioxide to form sulfuric acid when combined with water; this is the main component of acid rain is caused trees to die for a reason.
I am responsible for serious self-protection measures haze days: 1. Go out as little as possible. 2. Such as going out with two surgical masks (with N95 masks for the best). 3. Drink sufficient water, steady style occasionally drink, and drink plus kumquat tea. 3. Eat more fruits and vegetables rich in vitamin C, and added 1000 ml Madikwe C tablets per day. 4. Add 50 micrograms of selenium supplements every day, you can choose the body Vitamin Tablets HLM selenium to complement its malt Selenium is an organic selenium, to help the body resist carcinogenic effect is most ideal. . 5. Such as place of residence often severe haze days, bite resistance PM2.5 can buy air purifiers.
