Therefore, we must attach great importance to this matter. Whether it's newly decorated houses or new cars, we can smell a pungent smell, which is volatile gases in the decorating materials, such as formaldehyde, benzene, phenol, radon, ammonia, and an organic compound known as TVOC, and some of the rays in the marble will be directly harmful to the health of the people. The acceptance of these pollution can lead to a decline in the survival rate of male sperm, the increase of sperm abnormality, the decline of sperm motility, and the lack of menstruation in women, which directly leads to a decline in fertility. Some will have abortions and stop their development after pregnancy. When spermatozoa and eggs are damaged to varying degrees, they may cause genetic abnormalities to cause fetal malformations.
Radon is a radioactive inert gas, which is colorless and tasess. After the formation of radon in cement, sand and brick, part of it will be released into the air, which will form radiation after inhaling the human body and destroy cell structural molecules. The alpha ray of radon will cause cancer. Radon is one of the 19 carcinogenic factors identified by WHO, which is only inferior to smoking.
