One hour smoking cooking half an hour to smoke

China Interior Decoration Association indoor environmental monitoring center research shows that the kitchen is the hardest hit home air pollution.

Kitchen two main sources of pollution: gas, liquefied petroleum gas and other kitchen fire, burning may release carbon monoxide, nitrogen oxides and other harmful gases; cooking dishes produced fumes, and food at high temperature heating harmful substances.

In a poor ventilation system, the combustion efficiency is very low (gas is not fully burned) environment, the use of high temperature fried, roasted, fried and other ways to cook for one hour, the damage caused to the body, equivalent to smoking a half pack of cigarettes. At this point, if the kitchen environment PM2.5 test, its value will exceed 800.

Smoke in the kitchen, on the nose, eyes, throat mucosa has a strong irritant, can cause rhinitis, pharyngitis, bronchitis and other respiratory diseases, long-term inhalation of fumes, but also increase the risk of lung cancer.

According to the World Health Organization survey, this is an important reason that Chinese women do not smoke but are susceptible to lung cancer. Long-term exposure to fumes women, the risk of lung cancer increased by 2 to 3 times than normal, and the skin is more prone to aging, long spots. In non-smoking female lung cancer patients, more than 60% of the long-term exposure to kitchen fumes. Chef's incidence of lung cancer is also higher than the average occupational.

The key to reducing soot is controlling oil temperature. Edible oil heated to 150 degrees Celsius, will have a strong stimulating effect of acrolein, damage to the nose, eyes and throat mucosa; when the oil is heated to 200 degrees Celsius, the fumes produced more harmful substances; when the oil burned to 350 Celsius "spits fire" may cause "drunk oil" symptoms, long-term in such an environment, but also increase the risk of respiratory and digestive cancer. Traditional Chinese cooking methods such as frying, blasting, frying and oil temperature are all above 260 degrees Celsius, so it is unhealthy and should be minimized to be replaced by more cold, steaming, boiling, slimming and halogening
