The harm of natural marble is mainly manifested in radioactive substance-radon, which is a colorless, odorless and imperceptible inert gas. Building materials such as cement, brick brakes, marble and ceramic tiles are the main sources of radon.
There are two main radioactive hazards of natural stone, namely internal radiation and external radiation. In vivo radiation is mainly the radiation of radionuclides entering the human body as a radiation source, which further damages the system function of the human body. This radioactive nuclide decayed in the air enters the human body with the air, or adheres to the tracheal mucosa and lung surface, or dissolves in body fluids and enters the cell tissue, forming internal irradiation, which induces lung cancer, leukemia and respiratory diseases. In addition, radon has a high affinity for human fat. Long-term exposure will affect people's nervous system and make people feel depressed and sleepy. External radiation mainly refers to a biological effect produced by the radiator in natural stone directly irradiating human body, which will cause damage to hematopoietic organs, nervous system, reproductive system and digestive system in human body.
Harm of artificial marble
The harm of artificial marble is mainly manifested in the pollution caused by inferior materials. Because artificial marble is artificial, there are many uncontrollable factors. In order to reduce costs, some manufacturers use inferior materials in the manufacturing process. The raw material of artificial marble is the derivative of petroleum, which contains harmful substances such as formaldehyde and benzene. Some even directly add organic solvents and use inferior materials of heavy metals to produce a large number of "toxic marbles" with questionable quality.
Generally, this kind of board has the same characteristics, with pungent chemical smell and unnatural color. Formaldehyde and benzene will volatilize for a long time in the future, and then enter the human body, causing great harm to the human body. For example, formaldehyde is a chronic poisoning drug, which can cause nasopharyngeal carcinoma, nasal cancer, sinus cancer and leukemia. At the same time, inferior artificial marble is not only harmful to the body, but also has relative deviation in its own characteristics, such as low hardness, fear of scratching and coloring. This makes the maintenance of furniture even worse.
In nature, natural radioactivity exists objectively. Similarly, radioactivity also exists in natural stone products. The key is to see if it exceeds the national standard. Therefore, in the process of choosing natural marble, don't be greedy and cheap. Choosing good marble is the greatest guarantee for your health. The quality of artificial marble can only be guaranteed if the manufacturer issues relevant test reports when purchasing artificial marble.
