With the increasing awareness of ecology, health and environmental protection in recent years, people have higher and higher requirements for the quality of the living environment. The food for the people is the day, and the safety and health of the kitchen has also begun to receive widespread attention from the masses of consumers. In addition to the safety performance of kitchen facilities such as cabinets is becoming a hot spot of concern, the smoke hazard of the kitchen itself should also attract the attention of consumers.
Kitchen fume has a high carcinogenic rate
Soot is the most well-known source of kitchen pollution. The harmful gases such as carbon monoxide released from the combustion of coal, gas, natural gas, etc., and the carcinogens that are decomposed by food at high temperatures will increase the prevalence of lung cancer by two to three times. Among the more than 300 harmful substances contained in kitchen fumes, the most important lung cancer carcinogen is DNP. DNPs that housewives inhale when preparing a meal in the kitchen can reach 188 times the amount of outdoor fresh air.
According to a survey conducted by the Cancer Research Institute of Tongji University in Shanghai, more than 60% of the risk factors for lung cancer among non-smoking women are exposed to kitchen fumes; 32% of females prefer to use high-temperature fried fried foods, while kitchen doors and windows Closed or poorly ventilated. Another study found that the incidence of lung cancer among kitchen workers who have been engaged in the catering industry for a long time is higher than that of the general occupation.
Cabinet material affects kitchen air quality
The size of the cabinet accounts for about 1/3 of the kitchen, so its environmental status has an important impact on the air quality of the kitchen. Song Guangsheng, director of the National Indoor Environment and Indoor Environmental Product Quality Supervision and Inspection Center, said that the materials of the cabinets are mainly artificial boards, and the surface is usually painted. Artificial boards will use a large amount of adhesive during the production process, which will release formaldehyde and other pollutants into the room for several decades. In addition, the kitchen often uses open flames, and the temperature is higher, which is more likely to accelerate the release of formaldehyde and other pollutants. In addition, paint on the surface of the board may also contain contaminants such as benzene.
Countertops are also a source of pollution
The countertop is another source of pollution in the kitchen. In recent years, natural stone and artificial stone have been welcomed by many consumers. However, Hu Yunlin, senior engineer of the Ceramics and Stone Testing Department of the National Building Materials Testing Center, said that any material from the stratum is radioactive, and artificial stone is the same, only the difference between high and low. There are two kinds of harms to the human body caused by the radioactivity of stone. One is the X-ray emitted by the stone. Long-term small doses will illuminate people, which will damage organs such as bone, thyroid and breast, and induce cancer, but the probability is very low. The other is release. The sputum may induce lung cancer.
In general, marble is less radioactive than granite, and qualified artificial stone is less radiative than natural stone. It should be noted that a large number of adhesives will be used in artificial stone, so be wary of harmful substances such as formaldehyde.
