In daily life, the kitchen, there may be a result of indoor decoration pollution, cooking fumes from the formation of harmful substances pollution, the use of toxic substances tableware induced infringement, it must guard against the toxic and harmful substances from the kitchen to human health hazards.
National Indoor Environment and Indoor Environmental Quality Supervision and Inspection Center Director Professor Song Guangsheng In an interview with newspaper reporters said that in recent years, our country has undergone a whole kitchen by the installation of indoor pollution incidents caused serious endless, we must rise to the residents of the high degree of vigilance. For example, after five Qingdao Fushan district, Ms. Qi buy a set of kitchen cabinets, the house was filled with the pungent odor began to feel tingling voice, his eyes could not open. The authority inspection showed that the concentration of formaldehyde per cubic meter up to 1.56 mg, more than the national standard by 14.6 times, p-xylene concentrations, exceeding two times the total concentration of volatile organic compounds exceeding nearly 5 times more. Again, Guangzhou, a consumer signed a contract to purchase household as a whole cabinet, has been expressly agreed to use environmentally-friendly material that can be installed by third-party professional organizations, after testing showed that formaldehyde concentration in the kitchen more than 4.7 times the national standard.
The same can not be ignored is that generally used in a variety of stone kitchen countertop itself may contain radioactive material, if you choose incorrectly, you may cause radioactive contamination. Some people felt that the choice of artificial stone will not cause pollution, in fact, the use of chemical materials and powder made of stone also contains a number of chemical substances, should pay attention to chemical pollution.
SONG Guang-sheng, China's population used to use a lot in the kitchen cooking oil will inevitably lead to serious smoke pollution. At the same time, the kitchen using natural gas, liquefied petroleum gas combustion, air pollution is also very serious. In many parts of the use of coal stoves for cooking, but also produce sulfide, nitrogen oxides, carbon monoxide, dust pollution. According to an authoritative body to investigate, in recent years, the incidence of lung cancer in Shanghai women increased rapidly, especially between 40 and 50-year-old middle-aged woman suffering from lung cancer, the number of close male ratio is 1:1, which is subjected to second-hand smoke pollution of women, female smokers the rate of rise and is closely related to air pollution from kitchen.
Tongji University Cancer Institute recently published an up to 5 years of lung cancer, epidemiological survey showed that middle-aged women, long-term exposure to high temperatures in the kitchen cooking fumes, will make it an increased risk of lung cancer 2 to 3 times. In non-smoking female lung cancer risk factors, more than 60% of female long-term exposure cooking fumes, cooking, often with eyes and throat to stimulate the sense of smoke; 32% of women prefer to use high-temperature cooking oil fried food, smoke emitted toxic fumes from cigarettes on the volume is a thousand times a day in this environment to absorb the toxic fumes than in 1 hour more than smoking two packs of cigarettes. "Whether it's metal, ceramic or plastic tableware, mostly safe, but ignored the use of the characteristics of a variety of tableware, the tableware can also cause health hazards of toxic substances." Song Guang-sheng analysts say, people buy plastic tableware, it is best do not choose a color pattern printed on the product. The surface of many plastic tableware has a beautiful color pattern, if the pattern of lead, cadmium and other metals content exceeded, it will harm the human body. Plastic products in general the surface layer of protective film, this layer of membrane devices once they are scratched hard, harmful substances will be released. Inferior surface of the plastic utensils are often not smooth, harmful substances can easily leak out.
Ceramic tableware is a most commonly used household utensils, one of the glaze on the ceramic surface, but it may become a killer. Glaze of lead, mercury, radium, cadmium, etc. are all harmful elements, radioactive elements radium would be anti-white blood cells, cadmium and lead can cause poisoning, liver or other internal organs, mercury can cause liver and kidney sclerosis. The use of substandard ceramic products, these harmful substances will be dissolved, with the food into the human body over time can cause chronic poisoning.
Song Guang-sheng said that now more and more patterns of chopsticks, many people favor in the surface paint on the chopsticks. In fact, more than paint containing lead, cadmium, benzene and other toxic substances, among which the most toxic benzene as a carcinogen. Some unscrupulous merchants preferred to use unqualified production of wood chopsticks, and then use paint to cover up the material defects. Low-grade timber can breed mold, bring more harm to human health. Even the qualified chopsticks, when in use must also pay attention to rinse and regular disinfection should promptly air-dried after washing to prevent the breeding of bacteria on the chopsticks. Chopsticks used a long time, the surface would fatally smooth, easy to keep to keep impurities, provides a breeding ground for breeding bacteria. Therefore, each member of the family is best to use a fixed chopsticks, the chopsticks should be separated from each wash, at least once every six months to replace chopsticks.
