The U.S. Department of Health and Human Services (HHS) released the latest 15th edition of the Report on Carcinogens on 12/21/2021. The Report on Carcinogens is a congressionally mandated, science-based, public **** health document of the United States that is highly valuable as a guide for medical prevention. In the latest edition of the Report on Carcinogens, eight additional carcinogens have been added, of which Helicobacter pylori is classified as a definite carcinogen, and antimony trioxide, six haloacetic acids that are byproducts of water disinfection are classified as reasonably suspected to be carcinogens, as detailed in the link to the official report web page of the National Toxicology Program U.S. National Toxicology Program, as follows
? So here's a brief overview of the eight new carcinogens:
? 1, Helicobacter pylori
? Helicobacter pylori has long been recognized by the public as being related to the development of gastric cancer, as early as October 2017, WHO included it in the list of class I carcinogens, but also the most common chronic bacterial infections in human beings, mainly through the mouth - mouth, mouth - fecal pathway infection, according to the relevant domestic scientific research, the rate of Helicobacter pylori infection in China is between 40% and 90%. According to the relevant domestic scientific survey, the infection rate of H. pylori in China is between 40% and 90%, which indirectly proves that "ten people nine stomach", but not necessarily all H. pylori infections, so it is necessary to do in time for early detection and early treatment and early prevention, and the latest U.S. report on carcinogens, which further confirms that H. pylori infections significantly increase the risk of gastric cancer, and therefore will be added to the list as a definitive human carcinogen.
?2, antimony trioxide
? Antimony trioxide common form of the substance is antimony trioxide, an inorganic compound that is widely used in plastics, textiles, and other chemical products as a flame retardant and other additives used. Workers in the production of antimony trioxide are at risk of cancer due to prolonged exposure, while the substance may also be released in poor-quality furniture, carpets, or rubber and plastic items, leading to a heightened risk of cancer. In fact, as early as October 2017, WHO has also been categorized into the list of carcinogenicity of category II, so the product manufacturers to improve the awareness of workers protection and safety means at the same time, strictly in accordance with the national standard to add the use of practical maintenance of the user's rights and interests, and the user should also buy the regular manufacturers of qualified environmental protection goods, do not jeopardize the physical and mental health because of small losses.
?3, water disinfection by-products haloacetic acid
Water disinfection by-products haloacetic acid in fact, life is common after the disinfection of tap water haloacetic acid by-products , because the tap water in the production process will be a large number of chlorine-containing disinfectants, may be some compounds in the water with the reaction of the generation of haloacetic acid, which has a high risk of cancer. And it is difficult to degrade, volatilization, increased drinking water quality unsafe factors. The six new haloacetic acids in this report are bromochloroacetic acid, bromodichloroacetic acid, dichloroacetic acid, chlorodibromoacetic acid, dibromoacetic acid, and tribromoacetic acid. Although the tap water disinfection by-products, but as a member of the general public should not be too worried, because with the tap water disinfection technology upgrades as well as the development of filtration and environmental protection technology, coupled with the improvement of national standards for domestic water and factory control, tap water quality and safety can still be guaranteed, but also believe that as a matter of concern to thousands of people's livelihood project, the state has the ability to have confidence in the protection of us.
