2065438+071October 27 17 The list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization was preliminarily sorted out for reference. Talcum powder containing asbestos or asbestos-like fibers is in the list of three carcinogens.
Extended data:
Talc is one of the minerals. It is buried underground with serpentine containing asbestos, so it often contains asbestos in its natural form. Neither the National Toxicology Project of the United States nor the Occupational Safety and Health Administration (OSHA) of the United States listed talc as a known or possible carcinogen, so there is no way to say that asbestos in talc is carcinogenic.
The American Association of Government Industrial Hygienists (ACGIH) also lists talcum powder as "a carcinogen that cannot be classified as human beings". Talc talcum powder is still used in America. According to the International Centre for Research on Cancer (IARC), "talc containing asbestos" is classified as a carcinogen.
Talcum powder is closely related to asbestos, which is a strong carcinogen. Talcum powder particles have been proved to be the cause of ovarian and lung tumors in cancer patients. In the past 30 years, scientists have been carefully examining talcum powder particles and found the danger similar to asbestos. 1973 In response to this evidence, the US Food and Drug Administration (FDA) drafted a resolution to limit the content of asbestos fiber in cosmetic grade talcum powder.
