China Interior Decoration Association Indoor Environment Monitoring Center research shows that the kitchen is the most serious air pollution space in the home, its pollution sources are mainly two: one is from coal, gas, liquefied petroleum gas and other cooking fire sources released from carbon monoxide, sulfur dioxide, carbon dioxide, nitrogen oxides and other harmful gases; the second is the cooking dishes generated when the smoke. So, what are the hazards of kitchen fumes in the end? First, kitchen fumes can be invaded with the air into the human respiratory tract, which can cause loss of appetite, heartburn, mental fatigue, drowsiness, fatigue and other symptoms, medically known as the fumes syndrome. Many housewives are busy in the kitchen for half a day, making many delicious dishes, family members eat while praising, but the “chef” but there is no “appetite” is this situation. Second, kitchen fumes can harm the human sensory organs. Studies have shown that when cooking oil is burned to 150 degrees Celsius, the glycerin in it will produce acrolein, the main component of fumes, which has a strong spicy taste, the nose, eyes, throat mucous membranes have a strong stimulus, can cause rhinitis, pharyngitis, bronchitis and other respiratory diseases. Third, kitchen fumes contain a carcinogen known as benzo(a)pyrene, which can cause chromosome damage in human cells and induce lung tissue carcinogenesis by long-term inhalation. A cancer research center in the United States recently pointed out that in a survey on the incidence of lung cancer, it was found that housewives who engage in long-term cooking and chefs who work in an environment with high concentration of kitchen fumes for a long time have a higher incidence of lung cancer. In addition, the harm of fumes on the intestinal tract and brain nerves is also more obvious.
