We have the feeling that the kitchen will be dirty every day when it is cleaned every day, and some pollutants are always unavoidable. If the pollutants accumulate, they will cause cancer. Therefore, we must understand the root causes of kitchen pollution so that cleaning can be targeted.
(1) Pollution from the building itself
The pollution of the building itself is the first source of indoor "toxic gas". There are mainly two types of concrete admixtures used in construction. One is to add concrete antifreeze to the concrete wall during winter construction, and the other is to increase the solidification rate of concrete by using high-alkali concrete expansion agent. And early strength agent. The use of concrete admixtures is conducive to improving the strength and construction speed of concrete. However, these additives contain a large amount of ammonia, which will be reduced to ammonia gas and slowly released from the wall with changes in environmental factors such as temperature and humidity. At the same time, if the radioactive substances contained in the stones and bricks used in the construction exceed the standard, it will cause radioactive pollution that is very harmful to the human body.
(2) Pollution from decoration materials
In the process of kitchen decoration and cabinet making, various plywoods, veneers, wooden boards, reinforced and synthetic floors, etc. are widely used. The harmful substance contained in the adhesive they used-free formaldehyde, will gradually be released after decoration and during use. According to data, the national health, construction, and environmental protection departments have conducted a random inspection of interior decoration materials and found that materials with toxic gas pollution accounted for 68%. When these materials enter the room, they can cause more than 30 diseases in various organs such as the respiratory tract, digestive tract, and nerves.
(3) Pollution from cabinets
At present, the cabinet materials on the market vary from good to bad, and some cabinets and their materials contain formaldehyde, benzene and other pollutants. Relevant materials from the Indoor Environment Testing Center of China Interior Decoration Association indicate that indoor air pollution from cabinets has become the third largest source of pollution after construction pollution and decoration pollution. Some experts believe that indoor decorative materials, such as plywood, blockboard, medium-density fiberboard and particleboard and other man-made panels, have considerable pollution to indoor air.
(4) Pollution from daily life
People also unknowingly "produce" a large amount of toxic gases in their daily lives. For example, the combustion of gas in the kitchen and bathroom, cooking oil fume, and shower heating all produce a large amount of CO2, NO2, SO2, inhalable particulate matter, halogenated hydrocarbons, polycyclic aromatic hydrocarbons and other toxic pollutants; mousse, hair spray and hairdressing products, air fresheners, cleaning Chemicals, pesticides, etc. sometimes produce toxic and harmful chemical gases.
