Guide: The "Carcinogen Report" released by the US Department of Health on the previous day listed eight chemicals in the list of cancers or possible cancers. Formaldehydedyde, which is commonly found in building materials and homes, proves to be carcinogenic, and a large amount of exposure increases the risk of nasopharyngeal cancer or blood cancer. Styrene, which is found in plastic products and cigarettes, may cause lymphoma. The "Carcinogen Report" issued by the US Department of Health on the previous day listed eight chemicals in the list of cancers or possible cancers. Formaldehydedyde, which is commonly found in building materials and homes, proves to be carcinogenic, and a large amount of exposure increases the risk of nasopharyngeal cancer or blood cancer. Styrene, which is found in plastic products and cigarettes, may cause lymphoma. This is the 12th report of the National Toxicology Research Program of the US Department of Health. The last report was published in 2005. There are currently 240 chemicals listed. Formaldehyde is a colorless gas with a pungent smell. It is widely used in construction materials, including paints and wood products, so the newly renovated house releases more formaldehyde. Formalin, a medical preservative, contains more than 30% formaldehyde. Using straight hair products, smoking will also inhale formaldehyde. In the second issue of the Carcinogen Report issued in 1981, formaldehyde has been classified as a "reasonable expectation of carcinogens". The latest research confirms that the amount of formaldehyde absorbed by the body is related to the risk of cancer, so it is upgraded to "confirm carcinogens." Cao Hongwei, a guest professor at the Department of Biochemistry of Zhongda University, said that many items contain formaldehyde, such as plastics. They may degrade under exposure to sunlight and large temperature, and formaldehyde is released. The public will inevitably absorb it. However, he believes that the amount of formaldehyde that the public is exposed to every day is slight and there is no need to panic.
